Wave pocket clip on a Rebar (proof of concept)
on: September 30, 2018, 04:01:45 PM
In between challenges I occasionally have time to ponder... let me explain today's train of thought.
-The Wave challenge showed me how useful a pocket clip can be.
-Rebars have no OTS pocket clip option.
-Kick pocket clips are rarer than hens' teeth.
-Rebars have an identical pivot/lock indent layout to those of the Wave and Charge.

The musings have led to the concept shown below. It is not ready yet, the clip is wobbly as hell. Also, you need a Fuse pivot which I was lucky enough to still have.

So, how do I fashion a good connection between the clip and the handle that gets rid of the wobble and still allows inserting the pivot or its screw??  :think: :think: :think: Any ideas?

Why did you need a Fuse pivot?
In which direction/s is the wiggle?

I may have an idea, but just want to understand these two before sharing it

Thanks for thinking along 50ft-trad. The Wave pocket clip's end slips under the side lug of the handle in the pic, so I needed a bit (ca 1 mm) of extra space on the pivot's length for that. The wiggle is around the pivot's axis... I have briefly thought of welding, until I realised that I wouldn't be able to extract or insert pivots or their screws.

Edit: ... unless I made a hole the size of a pivot head in the clip. Kind of defeats the purpose.

It's a while since I handled or dismantled a Rebar, so that's not really helping me. I'll offer my idea forwards anyway, and even if it doesn't 100% solve it, it might give you enough food for thought to fix it.

Gimme a few minutes to sketch it up, and write an explanation...  :salute:

Ok, here goes... before I get into the "how to", I'm going to make a couple of assumptions. If these are wrong, let me know...

Assumptions:

a) The Rebar pivot is a flanged spindle with screw (pic 1), rather than a barrel threaded at both ends and two screws. If the pivot is the double ended barrel, you will need to Loctite/superglue one of the pins in to make it like my sketch.
b) The "tang" of the clip takes up the space of one of the tools, but is thinner than a tool tang. If that is the case, stack the tools that you want to put in that handle, including the washers, and measure the height. Also measure the thickness of the clip tang, and determine what washers are needed to build this up to the correct tool stack height for proper tensioning. You need to do this first, as with the method I'm going to offer, the clip is the last thing to be fitted.
c) As removing the clip would leave the remaining inner tools sloppy, the clip will need to be left on permanently.

Method:

1) Strip the handle down, and drill a small hole which intersects the radius at which the spindle flange would sit (pic 2)

2) Peen a small piece of brass rod into this hole, just as you would peed a Swiss knife mod, but ensure that the dome head is prominent on both internal and external faces.

3) Prior to assembly, grind and file a small notch on spindle flange and clip to coincide with the peened button (pic 3). This will act as a key to prevent rotation of both spindle and clip. Make sure the clip is a very close fit, to eliminate and side to side wiggle. The flange notch isn't as critical.

4) Insert the spindle into the handle, and load the tool stack and all the washers. Locate to spindle notch onto the key, and locate the end of the spindle into the hub on the opposite handle. Insert the screw, and tighten it just enough to hold the end of the spindle in the hub. Slide the clip into position, and nip up the screw. You might need to insert a small flat screwdriver under the clip, just to hold the flange on the key.

How does that sound?

NOTE: this uses the original Rebar pivot.

That is a very well thought out method, thanks 50ft :cheers: It would certainly work well :tu:

During my late afternoon stroll I have had an idea or two myself. Somewhat different to yours, and a tad less solid, but it would allow removing the clip without trace if I tire of it.
I'll illustrate it at the hand of a 9mm / 5mm washer but I'll need to source or fashion one with 4.8 mm inner dia. to fit exactly over the pivot with as little play as possible.

1. I'd thin the washer to about half thickness over an area corresponding to the blue shaded area in the pic, so that the remaining thicker portion fits exactly in the opening in the clip.

2. Then I'd bend the two ends of the clip up so as to radially constrain the washer when the latter is mounted on top of the clip.

3. The washer comes in after the last tool with the thicker remaining portion pointing outwards, then I pre-assemble the handle tools and pivot without tightening and without clip as yet.

4. Then I slip the clip in, which fits over the remaining thicker portion of the washer and catches it when the pivot is tightened.

That's the theory, at least...

Another option that u can explore is using the little washer found on the TTI at the lanyard pivot. This way you can insert and remove as required. Regarding the wobble, hmm.. I am thinking maybe filing either the clip or the frame a little might allow the feet of the clip to sit into the frame... Never try never know... :pok:

That is a nice thought Sam... do you happen to have precise measurements of that washer? Failing that I'm more than prepared to fashion my own...

Sam, is that the washer at the retractable lanyard ring? If yes, it should be standard on Waves too. One wonders if they've maybe coincidentally have made that the same width as the slot in the pocket clip...?

DT, yes that part is found at the lanyard ring but it's only available on the TTI/TI. Not on wave or even AL. Its a bushing to prevent the scales from collapsing the slot for the pocket clip. Wave uses a end cap. Charge AL uses something very different. Sorry I do not have a digital caliper to measure that.. According to my very wildly inaccurate eyeball gauge, its probably about 0.5mm thick..  :salute:

Thanks Sam. I'll have a peek at how the Wave solves this sometimes this week. Stay tuned...

Wave end cap with integrated spacer for the pocket clip slot, seen in combination with the clip. The blue arrow points at a small tab integrated in the end cap as well. That tab also holds the clip's longer of the two ends. That, together with the lock notch and the slot, is what keeps the clip centered. All of that will need to be reproduced somehow... :think:

Tested this out a while back and concluded that a dab of JB would be the go.

Some old pics over here. https://forum.multitool.org/index.php/topic,54488.msg948856.html#msg948856

Back then I also had a vague idea about milling a recess into the side of the large bit driver to hold the clip.
Down sides are not everyone has a large bit driver in their Rebar and having to remove the clip to use the driver.

Nice breakfast read.

Ordered some JB Weld. Considering to use brass for a collar ring bridging the gap between the pivot and clip slot... thin flange to separate the clip cavity from the file... Time to set up the lathe (hot-bunks workspace slot with 3D printer - not enough space  ::) :-\)

I have a bit driver but not in that spot, that's where my Wave file resides.

Made some progress today.

I have made a better version of the collar ring you see in pic 1 - on that one I botched the inner bore, but you get the idea. Pic 2 shows where the better one sits on the pivot. Pics 3 and 4 show how the clip sits on and off the Rebar VX - yes, it's still removable in case I sheath carry.

However, I am not entirely happy - unfortunately there is quite some residual wobble around the pivot axis... see pics below for the extent :facepalm:

 I fear that even making a small tab on the handle will not reduce this to zero as the tool lock is quite a bit narrower than the slot for it in the clip. I'll see whether I can live with this. After the Spirit challenge, of course :angel:

What if you drill a hole on the Rebar handle, press fit/ Loctite a pin in, which also fit into the Wave clip slot?
