Thread: 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 , 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 .
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!

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.....
