"How-to" for 58mm modding - Pic Heavy
« on: February 22, 2013, 04:12:31 AM »
I've got a couple of 58mm mods under my belt now and for tonight's mod, I took some pictures along the way to work up a "how-to" on the subject.

First up is required reading: go and read Gareth's thread on basic SAK modding if you haven't done so already. It covers a lot of the basics of modding that applies to any size SAK. Go ahead...I'll wait. http://forum.multitool.org/index.php/topic,9808.0.html

You're back? Good, let's get started. Here's what you'll need: a small ball peen hammer (I use 4oz, for this size I wouldn't go any bigger), an anvil of some sort (bench block, jewelers' anvil, sledge hammer head), 1/16" pin punch, drill and bits, 1/16" brass rod. An assembly board is useful and a parts dish is even more useful.

The knife being created today is a Vagabond, two layers with cellidor scales and six tools in total plus tweezers and pen. I'll start with my assembly board. It's a plastic cutting board with two set of holes drilled. One side for punching out the pins and the other set for assembly. The larger side (drilled through to 5/64" and halfway to 7/64") are for punching the pins out and catching the bushings at the same time. The smaller side is drilled through to 5/64" to easily accommodate the pin stock.

Disassembly of a 58mm donor knife:


Parts ready for reassembly:


The 'required reading' thread covered the majority of the drilling and disassembly process. Basically, during disassembly, make sure that you make a good center punch mark in the pins before drilling. During drilling, you don't have to go too far. I've found that when the bushing starts to spin with the bit, you're good to go. I'm getting better at saving the bushings nowadays, so hopefully you'll have good luck with it too. If not, grab a job lot of 58mm parts knives and go to town!

As shown above, I have the parts laid out for a Vagabond. The first layer:


Pins have been cut to length, filed to a point and the first liner set in place for assembly as shown above. If you're doing an alox knife, no liner is required here, simply set the scale in place.

Now, the first springs in place:


The springs on the 58mm (74mm as well) are unique to the rest of the line in that they're floating type springs. When setting them, remember: belly in. Easy for me to remember because that's what I think when I go to the beach. When placing the springs, I like to install the one furthest first, then the closest. That way, I can preset them by simply pressing down on the spring center and pulling slightly back toward me. It sounds more complicated than it really is.

Now, to install the tools. Have an idea of how you want to lay out your tools before you get started and the process goes so much smoother. There are two varieties of tools: single spring and double spring. Double springs are tools like scissors and the combo tools (ie, they require two springs instead of one). Most other tools only require one. For example, if you put scissors in a layer, you'll need two single spring tools (blade/nail file) or another double spring tool (combo tool) to accompany it. The spring set and tension against one another, so it's essential to keep this in mind when laying out your tool loadout.

When installing the spring, set the pivot end on the opposite pin of where you want the tool to live.


Set the tool onto the pin opposite the spring pivot end. When doing a double spring tool, I start with single springs on each side and build up from there. It'll hold temporarily with just one spring, don't worry. As shown below, here's a nifty way to tension the spring and set the tool.


Grab the ends of the spring with a pair of pliers (shown here with SAK pliers) and pull them together. When you've got them pulled together enough (it doesn't take much), the tool should set into place automatically. If not, give it a gentle nudge. Do the same for the opposing end and move up to the next spring layer.

On the next spring layer, work continues much the same way. One note: if you're setting a two spring tool, you set the spring the same way, but you'll need to push slightly down on the spring to set it in with the tool. Be gentle and it shouldn't pop loose on you. No worries if it does pop, just set it again.



When you're done with a layer, install a liner and continue on:


If you're doing a USB knife, always install a liner before and after the USB layer. That'll keep the springs from popping off. The USB is easy to install (not pictured though). It's three brass bushings and the plastic tab with keyring. Decide where you want the keyring, install it there and put bushings on the other three pins.

Setting the scissors:


Assembly of the second layer mirrors the first. Again, having a good idea of your tool layout makes the assembly process so much smoother. In this case, I used a pic of a Vagabond as a reference.

Last liner and the peening process ready to begin. Again, if you're doing an alox knife, the outer liners are not required; the scales themselves serve as liners also.

Bushings installed and cutting the pin to length using a liner as a gauge (I read about this technique here, not sure who to give credit though...whoever you are, thanks!).


I couldn't get a good pic of the bushings to show their orientation, so remember: the lip of the bushing should be at the top. While the knife is on the assembly board, you can cut the pins to proper length and file/peen the ends enough to fill the bushing, then finish peening on the opposing side. You'll waste a little bit of pin stock using this method, but it's a good tradeoff in ease of assembly.

Finished peening:


On the subject of peening, a little is a lot. After you cut the pin to length and file it down good and flat, make sure that you only have at most 1mm standing up from the bushing. Too much and you'll end up cracking/bending the pin before it's peened. I use a dime as a gauge (a dime is 1.3mm thick) and eyeball it from there. I shoot for .8 to 1mm to start peening.

As shown above, a proper anvil surface is essential (I use a bench block, heavy block of steel). You can literally see the pin forming into a rivet head with each hit of the hammer. Use relatively gentle hammer blows; the weight of the tool will do most of the work for you. Let it.

Your goal here is twofold: fill the bushing and eliminate side play in the tool served by that pin. Once the side play is good and gone, you're done. I like to start with 4-6 blows on the center of the pin followed by finishing up with mushrooming the head by hitting around the edges. I've found that getting most of the play out at first in all four pins, then fine tuning it from there is quite effective. Don't overpeen or you'll have lazy, binding tools (ask me how I know :P).

And now...the money shot!



Red scales installed with tweezers and a pen scale on the back side. Hope you guys enjoyed this (or I at least cured your insomnia) as much as I enjoyed building it!  :climber:

Hey thanks for taking the time to post up all the pics.  :tu:  I love to see how other folks work on SAKs.

So far Ive only tore down one 58 rambler, but I have an obscene amount of donor 58s coming in, and Im excited to build my mini monster.  Still scratching my head on how to include the T&T on an alox version, but I think maybe making an inner layer that takes them is the only way to go.

I think the idea on the monster 58 build page would work just fine.

Perhaps a "Lord of the Stickies", One sticky to rule them all?  Just one with a "How-to" label and links to the appropriate knife types.  Problem is that it would have to be able to be edited after the editing cutoff has passed, and a mod (or two) may have to babysit it to add new links.

If not, then stick it because the info is very useful, and I've found that searches can be frustrating due to the nature of overlapping topics.

(BTW, Nice job on the mod! :tu:)

If you can't fix it with duct tape, a hammer, a screwdriver, bailing wire, zipties, or a Swiss Army Knife, it's broken and irreparable.

That might be faster... hmm.  I started prototyping one from polycarbonate to see how I like the idea though. I just have to cut the channels for the T&T.  I couldnt decide it it should clear or solid.  I'll make one with the polycarb and if I dont like it, I'll probably do polished Ti as I have some scrap the right size.  Luckily 1/8 material works perfect and since this is for a monster extra width isnt a big deal.  :D

Both tools actually fit nicely horizontally, but its not possible to actually remove them once you have liners on, so that method pictured is the only decent way to do it that I can think of.  Its just a matter of leaving the tiniest lip exposed to get them out.

I'm not familiar with the specs of the knife you are making, but would a pen/stylus fit too?

Not to hard. The harder part is getting the rivets to look good.
