Title: The Mega84
Post by: AimlessWanderer on August 30, 2015, 05:49:09 PM
..... has begun  :ahhh :ahhh :ahhh

There's a couple of SAK mods I've been considering for quite a while, and after a lot of patient searching and spending, I finally got the parts together that I needed about 12-18 months ago. Since then those donor knives have just sat in a drawer, untouched (though occasionally carried/used)  ::)

I've spoken about doing SAK mods, bought donors, sold pin stock, and even advised on doing SAK mods, but never actually completed anything more than a scale swap  :facepalm: Time for that to change, and the whole point of me making this opening post is to make it significantly more difficult for me to bail out of the uncompleted project  :rofl:

Obviously, the advice given is to start small and do a simple cheap mod which doesn't matter if you wreck it, and obviously I've completely ignored that and gone for the most expensive and ambitious project first :dwts: Two of the five (yes five) donors are broken down, the first ambitious part of the project has revealed that it's not as straight forward as I'd hoped (needs some thought and careful grinding), and my right thumb has failed a N_N_R style impromptu skin durability test  :whistle:

More to follow later, once I've overcome the first obstacle....

Beer number one finished

So....

Problem two is bigger than problem one

I may be able to fix problem two. Unconventional, but could work

I have enough tools for three attempts at solving problem two, but there is a risk of causing backspring issues, and I only have one spare backspring.

If problem two is not solved, this might mean I have to address problem one in a different way

I need to get problem one fixed first time, as there are no spare tools

Therefore, solution for problem two needs a test build to prove the concept.

Once the tools are modified and concept proven, they can be reused in the finished build and I'm all clear to regrind to other tool to fix problem one

..... I think  :think:

Beer number two opened

Well I've been doing my 84mm mod for the last 3 years and it's still in parts. :doh:

And my 85mm Urban will probably be taken apart and redone in a different configuration soon. For the 4th time. Or is it 5th. :facepalm:

So yes, I understand your pain. ;)

Whether or not this works well enough, influences what goes up for sale next. I kind of need to do the awkward one to know if the easier ones are worth doing. The ironic part though is that to build this awkward one, I'm actually breaking down a few knives that are hard to come by.

If I can get this one to work, it's more likely to see frequent pocket duty than the other two mods I have planned. It won't work as I originally imagined it, but I just need to decide which feature to sacrifice in order to retain the others

Title: Re: The Mega84
Post by: AimlessWanderer on August 30, 2015, 09:59:16 PM
Ok, here goes.... this was the original plan:


93mm Awl                     Plain Blade
(corkscrew with mini driver)

Scissors

Saw

Nail file                            Serrated Blade
(round can key Phillips mounted backwards)

Bottle Opener                    Can Opener
(awl slot vacant to allow space for reversed Phillips)


Problem 1:
93mm awl sits way too high. IF the awl remains in this position, a modified kick should allow it to drop low enough to have the point below scale height.

Problem 2:
The tang on the Phillips is not symmetrical like I thought, which means it can't be reversed


Option one:
Bring serrated blade layer forwards to allow Phillips to be kept in same orientation. This moves the can opener back a layer, plus one extra spacer (needed as awl backspring isn't quite thick enough to provide a big enough void). This means the can opener might work on some smaller diameter cans, but not on larger ones.

Option two:
As option one, but grind can opener into a technicians driver

Option three:
Shorten tang on Phillips and re-drill at the other side. This allows a slightly shorter Phillips to be inversely mounted. Liners would need modifying, and this is VERY risky, with no second chances

Option four:
Shorten tang on CORKSCREW and reduce the other end by half a turn to put the point "safe" when mounted backwards. Mount Phillips "correctly" in outer slot.

Option five:
As option two, but ditch the awl and use combo tool to recover can opening ability

I reversed a phillips on a Ti 91mm mod and boy what a pain!  I filled the hole with brass, then drilled a new hole, AND had to change the angled part of the part that mates with the back scale.

Thanks Robert  :tu:

Personally I considered filling the hole, but using brass could lead to galling (brass on brass) and I'd have to use a drill press with a core drill to avoid push off between the two metals and stop it favouring the brass.

I'm using a cordless drill on my kitchen table  :facepalm:

Only other option for me would be to go and have a work with an old mate to see if he could TIG weld it up for me, then grind flush, then drill. Risks there are thermal distortion, and if the weld chills I'm back to needing a drill press

EDIT: gorgeous looking mod BTW  :salute:

Oh for the 93mm awl, you have to relocate the pivot hole on that one as well and regrind the pivot to be the same shape as the other 84mm tools.  It works as is on a 91, but not on an 84.

Post by: AimlessWanderer on August 30, 2015, 10:57:02 PM
Oh, I was just going to regrind the kick so it closed further. Will that not work? I realised the arse end will be stuck up a bit, but didn't think it was a full tang rework. Was it just to get it to sit parallel, or is there something else I've missed (so I know what to watch for when I'm doing it)
Title: Re: The Mega84
Post by: AimlessWanderer on August 30, 2015, 11:28:23 PM
I think tomorrow I'm going to try option 2 as described above and see how it works out. All I'm sacrificing is one can opener, and there'll be a couple of spares from the other donors if I change my mind later.... in fact I might as well build it up in tact first (option 1), and see what cans it might work on.

I know the awl will sit dangerously high at this stage, but it'll give me an overall feel of the knife and guide me as to subsequent changes.

Thanks mate  :cheers: That makes more sense now. I'll do the test build tomorrow and see how sensible everything looks. I'd rather not go to that extent on the tangs if I can help it, and I need to see if I can make it work (for me) a different / easier way. I don't have the time or facilities for anything too elaborate. Grinding a little off here or there is one thing, but reforming and redrilling entire tangs is not what I had in mind  :D
Title: Re: The Mega84
Post by: AimlessWanderer on August 31, 2015, 03:10:09 PM
All knives are now apart, and the micrometer and vernier calipers have come out to play. Due to the assorted ages of the knives, the main blades vary from 2.0mm to 2.4mm. This actually does me a favour though, as the tang on the 93mm awl is thicker than a standard 84mm nail file, small blade, or combo tool.

Awl plus segmented spacer = 2.8mm, so I need the thicker spring. However, the thicker spring only measures 2.3mm. I also need to use selective assembly on the liners too. They have differing offsets where they have been stamped, giving different effective thickesses at different points, and I also need to carefully choose another layer for modification. Due to the configuration of the knife, I need three liners with the corkscrew/phillips cutout, but out of these five donors I only have two (from the Salesman and Sportsman).

Once I've matched everything up as good as possible, modified the liners and tangs as necessary, I still need to make a couple more decisions; firstly whether any additional washers are needed to get smooth function but also let the scales sit flat, and secondly whether to use any of the stock scales or something different  :whistle:

Cutting up the b/s awl to make a tapered backspring support with no vice a cordless drill and a few handtools is f-f-f-frustrating to say the least

Yes, I think I'm pretty happy with that!

Still needs a little bit of tweaking and adjusting, but conceptually at least, it does seem to work. Awl sits low enough to be safe, Phillips tucks away nicely, but can still be accessed, and whilst access to the cap lifter and nail file is a little fiddly, it can be done.

I need to accept a little bit of compromise on a first ever build with bloody awkward layout I suppose  :D

Post by: AimlessWanderer on August 31, 2015, 11:46:41 PM
It's not got the rights segmental spacers on the awl and nail file yet, and the liners down the centre of the Phillips need opening up a little so you can access the driver easier from the end. Other than that, it seems pretty functional which is the main thing.

I think with this being my first build, and somewhat of a mismatch of parts, I might be safer peening it up with the bushes I've salvaged, popping on some nylon scales, and giving it some carry time. That way any problems have got chance to identify themselves before I start thinking about making scales for it
Title: Re: The Mega84
Post by: AimlessWanderer on August 31, 2015, 11:51:47 PM
It doesn't feel to unwieldy a pocket knife either. It's quite a weighty affair, but with that amount of function it's unavoidable really.

My main aims were to build an scissor laden 84mm with both phillips and corkscrew, and both serrated and plain blades, but without losing the awl. The saw was a bit of a "why not" rather than "must have", and the nail file seemed logical with already having full size plain and serrated blades.

I say use the small blade instead of the nail file :poke: It works better for some tasks. But does a 91mm one fit the 84s frame? I kind of hate the 84mm small blade.

The wood saw adds heft, I'm not sure a metal file wouldn't be preferable. I know this means more modding and perhaps getting a file too but for this size that would be my pick.

I thought you didn't like nylon scales? :popcorn: anyway...


Oh, and inline awl  :drool: That one's lovely, yeah!

It's MUCH harder trying to find an 84mm file than any other tool in the 84mm range, and one thing I never got hold of. It was available a couple of times, but at a price I wasn't prepared to pay, particularly not for just breaking it down for parts. I could have cheated and used a Wenger file, but I reckon I can make do with the nail file.

As to the small blade, I don't like having two plain blades on the same knife if I can help it. That's one of the reasons I liked the Traveller over the Climber. The pruner blade that's left over from the Rancher I stole the awl from, will be destined to go in a CT41 with a serrated blade from a Weekender. Two distinctly different blades again, and which takes inspiration from the Original Outdoorsman which is another favourite of mine. I'd imagine a 91mm small blade would be different to an 84, so that would take work too. Besides, I have to have two full blade layers to get the Phillips and Corkscrew in, so adding a third blade instead of a different function just seems a bit of a waste  :think:

Nylon scales? I like the ones on the Voyager, and don't mind the ones on the 84s. They are a bit more durable than the celidor, and they do have better grip when wet, but I do still prefer the feel of celidor on the whole. I much prefer the nylon to the feel of alox too  ;)

Ya very nice! 

Its funny I am tackling the same issue right now on a 91mm job that needs both backside phillips and corkscrew.  The problem is I have less space to fit the phillips, so I milled it flat on each side, (kind of looks like a flat leatherman phillips now) but it should fit in space I have for it now. Im using 2x saw backsprings with backtool cutouts to house the phillips.  It should work but it hasnt gone together yet.

Cheers Bob  :cheers: I was originally hoping to get away with not having to add that second liner, but as it happens they were needed anyway for access to the nail nicks on the cap lifter and nail file. They're still tight, but doable with my nails, and would have been impossible with one liner. The awl worked out well too with just a sliver ground off the kick :tu:

Are you using an inline Phillips for that mod, or have you milled it offset? I wouldn't imagine you could afford to lose much off the tang side of a backspring Phillips  :think:

Hmmm.... the lack of a vice is hampering my abilities to get one end of the pin peened before building it up  :think:

I tried just standing the pins on end on my mini anvil, but that just bent the pins. I then tried using a G cramp on the garden fence, but that didn't work either - not secure enough. I think I'm going to have to try NOT pre-peening, having excess on both sides, and then cropping/filing/peening both sides together. That'll be interesting....

That actually works BETTER than a vice. Drill tucked under left arm, turning chuck with left hand, and rapidly hitting with hammer in right hand whilst slowly turning the chuck. It's like a mini GFM forge  :D Perfect!

I really can't believe how well that works. They've actually slightly "over peened" and don't quite seat in the bushings, so I'm just tickling them up with a file. It actually gives a nice domed and burnished finish.

Alox modders take note!

:rofl: BRILLIANT!!!!!!

Grip pin in chuck, set to hammer, and "drill" the side of an axe head at a slight angle! Just enough pressure to get the hammer action to kick in, but not enough to bend the pin. A perfectly pre-peened pin in seconds  :D

WE DEMAND A VIDEO! :ahhh

:D

Hear, hear!  :whistle:

-----------------------

I was referring to a 91mm metal saw earlier; I know 84mm ones are hard to find. Besides, newer ones are better ;)

I'm probably too late for this but what if you turned the pruner balde to a wharncliffe, a sheepsfoot or a bevel point? More function then.  >:D  :)

It was your preference of cellidor that I recalled, then.

Now you've got me thinking about a mod I had in mind... Will you be modding a Wenger next by any chance?  :ahhh

No vids, sorry.

I was tempted to use the MFV blade for turning into a wharncliffe actually. Unfortunately, it's only 2.0mm tang thickness and I need the 2.4 due to the awl tang thickness.

Yes, Wenger may well be next, but that's (hopefully) a MUCH simpler project  :)

Awl spring is protruding a little, which means the Phillips is sitting high. I've marked it up with a sharpie marker to see if it can be reprofiled without compromising the spring under the cap lifter

I so envy you folks that have the skill to mod these SAKs. As SAKs are one of my favorite things, I like them even more for the fact they can be customized with so many different parts/implements as I like to call them. I've pondered over what would make my perfect SAK and it changes almost daily. Currently, I am quite content with the Swisschamp, but would actually like to add a pruner blade and electrician blade to it, along with possibly some other implements.

I think the SAK I really want is the XLT (correct me if I'm wrong), the one the adds the pruner, elec. blade, and cyber tool.  ???

Anyhow, whenever I see a mod like this it gets the gears turning in my head and if I could afford the overhead, I might even get into modding myself!  ::)

Its hard to think of what else you'd be able to add.  Pliers would be kind of impossible to add on an 84, so the only other thing you could go for would probably be a metal file/saw.  It would work on the wood saw backspring, but youd have to shorten it to fit.

I stopped working on 84s as it was much more difficult than any other size to work on.  I still get alot of requests though for cadets with scissors, so someday I'll get back to working on that size.

So far as this goes, I certainly wouldn't call myself skilled. I just winged it  :D and it was all done at my kitchen table (apart from the peening - table wasn't up to it, so I used the concrete step outside the back door) without any special tooling. The right size nail could be used for a punch. A large hammer as an anvil.

As to the XLT wishes, my next Vic mod will be a Cyber-Outdoorsman. Take a CT41, ditch the pliers, and switch the large and small blades for large serrated and pruner. However, I've not completely abandoned the idea of also breaking up a Voyager Lite, including the Phillips and torch layer, switching the hooks over for the nail file on the back, and of course having the alarm clock scales.

In the meantime I have one more mod to look at. A simple (hopefully) Wenger upgrade  :)

Yeah, I think the best thing for pliers on an 84 would be to start from scratch, and conjure up something like they have on the Rangers with the triple backspring. Not a job for at the kitchen table though  :D It would have been nice to have the metal saw in there too, but that might have been one tool too many. At the minute it's a very good size and weight, and isn't too unwieldy or obtrusive.

Well, I'm very pleasantly surprised!

Despite the can opener's compromised positioning, upon offering the tool up to a range of different sized cans, it seems the can opener should work fine on cans of up to 85mm diameter (standard cans being around 75mm diameter). So standard cans will be fine, but larger cans may be a problem. I can live with that.

Very clever with the Phillips   :tu:

Thanks Tommy  :cheers: It took a while to figure out how to make it work, but it took a lot longer to get the right donors together  :D

Ya very nice! 

Its funny I am tackling the same issue right now on a 91mm job that needs both backside phillips and corkscrew.  The problem is I have less space to fit the phillips, so I milled it flat on each side, (kind of looks like a flat leatherman phillips now) but it should fit in space I have for it now. Im using 2x saw backsprings with backtool cutouts to house the phillips.  It should work but it hasnt gone together yet.

Cheers Bob  :cheers: I was originally hoping to get away with not having to add that second liner, but as it happens they were needed anyway for access to the nail nicks on the cap lifter and nail file. They're still tight, but doable with my nails, and would have been impossible with one liner. The awl worked out well too with just a sliver ground off the kick :tu:

Are you using an inline Phillips for that mod, or have you milled it offset? I wouldn't imagine you could afford to lose much off the tang side of a backspring Phillips  :think:

I got my version done, here's what it ended up looking like.

(http://i1117.photobucket.com/albums/k587/Syph007/Custom450Plus/Custom459/IMG_8996.jpg)

I only shaved off 0.020" from the pivot side, and more from the other side.  It technically less strong than before, but a compromise to fit it in the space I had.  :D
Title: Re: The Mega84
Post by: AimlessWanderer on September 02, 2015, 09:02:57 PM
 :salute:

I figured you'd have to offset machine it  ;) It's ended up a little like the Phillips on the Bucktool  :D It won't cause your customer any issues though, even the reduced thickness tang should still take more torque than a normal peened assembly would allow anyway  :tu:
Title: Re: The Mega84
Post by: AimlessWanderer on September 03, 2015, 01:38:01 AM
After a couple of days carry, there's a bit of side to side play in the main blades, and there's certainly more daylight between the springs. I think the pre peened heads done with the hammer drill, have "settled" in their respective bushings. I had a suspicion that might happen when I was peening it up.

As regards the overall concept, version 1 has certainly proved itself though, and the knife was not meant to be considered finished at this stage anyway. I'm still not happy about the nail nick access on the bottle opener either. Yes, I can dig it out with the tweezers if necessary, but that's still a bit sloppy of me to accept that.

Looking at where the nail nick sits on the serrated blade in front of it, this could afford to drop a couple of millimetres, as it's not got to sit over the cap lifter or scissors like on other knives. This means I could adjust the kick on that blade slightly so it sits lower, although I would also have to shave some off the segmental spacer next to the nail file to give it the clearance it needs without fouling the blade
Title: Re: The Mega84
Post by: firiki on September 04, 2015, 11:15:31 PM
:think: Could you post a pic of the nailnicks, showing the SAK diagonally from the pivots? I can't visualise the thing in my head.

One thing I now, that 84mm mod is probably just a bit thicker than a 91mm Ranger!

Title: Re: The Mega84
Post by: AimlessWanderer on September 05, 2015, 12:05:00 AM
Ok, here goes..... four pictures

Pic 1
From the end you can see the additional liner has improved access a little bit, but even so your thumbnail is a little too vertical from the bottle opener nail nick going up over the spine of the serrated blade in front

Pic 2
With the serrated blade open, the bottle opener nail nick is perfectly accessible over the top of the nail file. Not shown is that the fail file's nail nick falls exactly where the slight "dip" is at the meeting of the bottle opener and can opener, and I can dig this out with my index finger just fine.

Pic 3
With the serrated blade closed, too much of the bottle opener's nail nick is obscured. At the moment the easiest thing to do is either open the serrated blade first, or use the tweezers to dig the tool out

Pic 4
If the serrated blade could be lowered slightly into the knife, it's nail nick would still be accessible, but access to the bottle opener would be improved
Title: Re: The Mega84

Sorry it took me so many days to reply  :-[ That life thing gets in the way  :ahhh


I don't have a real solution, just wondering if moving the openers layer next to the other knife blade could work.

Otherwise, I'd be tempted to just drop something like a mini-sewing kit under the bottle opener to make it stand a little higher, in case that improved nailnick accessibility. Lame, I know  :facepalm:
Title: Re: The Mega84
Post by: AimlessWanderer on September 10, 2015, 02:06:35 PM
No problem at all  :cheers:

The opener layer needs to be in that position. The backspring has the cut out for the standard awl which I've used to accommodate the extra thickness of the backspring Phillips.

Next time this knife comes apart, I will be looking at lowering the height of the knife in front, and I have had an idea for making the bottle opener sit slightly higher by reworking the tang slightly, but I haven't proven the concept yet.

I know what you mean about life getting in the way, that's why there's been no more changes to this yet  :D

<snip>


The Mega84 has been taken out of service  :-\

Yesterday I developed a bit of a creak which sounded like a liner moving on a pin, and at that point I decided to put it aside until I do V2 of this knife.

I had only ever intended this version to be proof of concept, which it has passed with flying colours. However, there's obviously been some movement of the pins, either due to incorrect peening, or the peened heads pulling into the bushings. The original plan for V2 was for brass liners and nylon scales again, but I'll probably end up moving straight to the final version with homemade scales I reckon.

Won't be anytime soon, as there's too much other stuff I have to do first. I'm quite happy that I managed to get some good use out of this before it started developing issues though  :)

I read the whole thread but didn't see anything about where you got the serrated blade. (Maybe it's there but I didnt find it) I know a weekender has the serrated blade...that fits on 84mm? Or is there an 84mm model with serrated blade? Or did you just serrate your own? Looks like a factory serration.

I'm not doing as crazy of stuff with the back tools, just wanted to put serrated blade/nailfile on a backspring I have from a Lumberjack. (No back tools.)

I have all the other donor knives descaled, using Golfer, Sportsman and Lumberjack.  Considering reshaping  91mm metal saw if I can get another 84mm WS backspring.

I have done some serrations by hand but I'd really like a factory look, maybe I can build some kind of a jig for spacing....maybe do a run of serrated blades? I dream too big.

I'm not sure where Fiddy got his serrated blade, but there is/was a serrated Recruit: http://www.sakwiki.com/tiki-index.php?page=Recruit

Sorry, only just noticed this  :oops: the serrated blade did indeed come from a serrated recruit, which I got from the trade forums here ages ago

The Mega 84 is awesome.  Great mix of tools.  This would effectively replace the need for me to carry a 58mm for finger nail duty,  and would cover food prep too. I want one.  Too bad I don't have mad modfing skills and a bunch of parts.

Thanks Mizedog.  :cheers: it took me a while to accumulate the right donors for it, but as for modding skills, it is one of only two knives that I have built from parts. I am still very much a newbie in that respect.
