Large pinhole

Yesterday I disassembled a 5/8 wedge with busted scales.
I already have the wood for the new scales, and Joe has sent me some pins and washers, but the pinhole is rather wide.

If I were Lou my description would probably involve an elephant :roflmao, but I'm not so I will give you the exact size: 3 mm.
It is a bit un-even too, so If I'd have to drill it out I'd have a hole of 4 mm diameter.

I think the best thing to do is to drill it out, and insert something to fill it up, with a small pin-sized hole in the middle.

But before I am going to search for such a thing, I'd have to know what you'd call it in english.
Anyone?

Dumbo just called, and he's NOT happy. If I were you, I'd head for higher ground, cause he's coming over to your house, and he's gonna' kick your sorry butt!


If you could drill it out to 4.5mm, something like this might work.

As long as it is only a butt kicking I'm not too worried :D .
4.5 mm should not be a problem. I'll check it out.

Thanks Lou.

I'm here to serve.

I recommend a small bronze bushing, tube or piece of rod. Drill the hole out to just smaller than the OD of the bronze, then press in (a vice will work in a pinch) or tap in with a hammer. Then drill the hole in the center if needed. In lieu of bronze, use copper or even a hard plastic. On last thought is an epoxy. Fill the hole, let it set and drill the 1/16 over the pin OD in the epoxy. good luck - John

The last time I was in Thailand, a buddy and I jumped on an elephant and went into town to get a beer - as I was coming out of the bar, I noticed my buddy standing behind the elephant, intently staring up underneath the tail.
"What the Hell are you doing??", I asked...and he answered:

"As we were riding into town, when we passed those two farmers, one of them said 'Look at the two a$$holes on that elephant!'



I'm here to serve...carry on!

-whatever

BTW: That's NOT an elephant joke!

I vote for John's initial suggestion. You may need to shave some metal off the 3/32 bronze tubing to make it fit, but once you get it in and get the pin through it, you get a very tight and stable setup.

Tubing?

Isn't it usual for the tube walls to be thin, compared to the width of the center hole?

If I understand correctly, I would need a tube with an outer diameter of ~4 mm and an inner diameter of ~1 mm?

How does that correlate to the size: 3/32" ?
Of what is that the measurement?
Sorry for the confusion, but I am not used to working with empirical units in a mechanical environment. I don't know what 3/32 means.

3 32dnths of an inch

so... it would be (25.4mm/32)*3= 2.38125mm

I was going to recommend brass tubing as well (through both scales and razor), for a 1/16" brass rod for the pining. I have some pins with rivit like collars. The rivit/collars would pass through the scales and fill the hole, leaving a brass collar on the outside of the scales. The pin could be peened over like any brass rod. I'll try to scan it, and post it here, when I get home, but if you are interested, PM or email me (taztu at hotmail) and I can send you a few. I've never used them myself since I have not had the problem you are facing, but I have a feeling they are just what is needed to fix the problem.....

Since the hole is irregular, chances are some parts of it will be narrower than the tubing. I had a couple of choppers like that. So I needed to grind a bit of metal off the outside before cutting the end and gently tapping it in there with the hammer. Once the pin went through, I ended up with a tight, smooth-operating setup.

OK, here is the image of what I was talking about earlier with the 'rivet collar' pin set up...

This might help, or something like it for that oversized hole problem.

Let me know if you want me to send you a few....

Thanks for the offer Chris. I am assuming using these would entail getting my hands on a rivet gun?

Nope. Not at all! (Unless you want to use them as an excuse because you have always wanted a rivet gun) ;)

You'd just peen over one end of the rod (I think one might already be done), and use the rivet-collars in the holes, what sticks through the other side (inside of the scales) you can file/sand flush with the inside of the scales. Then repeat on the otherside, and pin the scales as if you had a 'regular' set up. The 'rivet collars' would work in the same manner as the small washer or regular collar, only these have a little tube attached to fill that oversized hole.

Sounds a bit complicated but I'd like to give'em a shot anyways. You still keeping that envelope with my addy around? :D

P.S. Thanks :tu

Um, er, well...no.

I'm bad at keeping address and numbers, so I'll need that again. PM me the details again, and I'll send a few your way. How many do you need (2, 3...)?

Just let us know how they work!

C utz

2 would be fine, enough to pin one razor as an experiment. The PM is about to be sent. I hope that everyone sees what a nice bunch of gentlemen we cultivate here :tu

Yesterday I received Joe's pins.

They are of course a lot thinner than the hole I am trying to fill.
I was thinking about drilling out the hole and then plugging it with a 4 mm wide brass rod.

I could then drill a small hole in the brass insert to use as a pin hole.

The only problem is that I only have metric drills, so the pin hole would be 2 mm whereas the pins would be 1.6 mm.

How much of a gap is there usually?
if .4mm is too much i'll buy a 1/16" drill.

First off, you don't need to. It worked before, it'll work now. Most of the holes in old razors (particularly Sheffield razors) are uneven and way too big. They were hot-punched during the forging, and not drilled. If you must clean it up, the above suggestions will probably work. You can also fill the pivot hole with J-B Weld, let it dry, sand it flat and even with the shank, then drill a new pivot hole the size you want. The scales will cover this area.

I just wanted to let you gentlemen know that mine arrived today. Thank you for being much more timely than me Chris :tu

Wow, that was faster than I expected it to get there....
So? What do you think, will it work?

Let us know, and if you do use them, post pictures.... I've never used those myself.

Sorry Chris, I should have posted something immediately. I believe that these will work with razors that do have large pin holes. Some may need to be trimmed a bit, but all in all, I'm highly optimistic. Feeling kind of sorry that all of my project pieces have nice and tight 1/16 virgin holes that would be too small. I'll look into the bin and see if I have a larger Sheffield piece lying around.
As for speed. I made a poor fella wait for more than a week before I could ship out the Cr2O3. :w
