The Illustrated Guide to Sleeving an Oversized Pivot...

I needed to sleeve this W&B before pinning the scales so I tried to get some pics done... I apologize for the final pic I even took two and they both sucked...

When you have an over-sized pivot hole you need to fill that space, you have some options here, some people fill the entire hole with epoxy and then re-drill the hole, some use a combination of a sleeve and the epoxy... Myself I just sleeve it as close as I can get it .... My theory is that these razors have been riding around on 1/16 rods for about 100 years so any thing tighter will probably last another 100 years.... I have a few different sizes of brass tubing in the shop starting with this stuff with a 1/16 ID hole, all of them slip into one another, so I can increase the size of the OD without any trouble (I use the same principle for making brass center pins)
Once the razor is ready to pin I chose the closest sized tubing to the hole, sometime like this razor, I only have to use one sleeve, sometimes two..

I cut the tubing to approximate size so it will fit inside the tang without rubbing...

Attachment 20811

I fit it, then smooth up the edges

Attachment 20813

The easiest way I have figured out to do this is to put the sleeve over the pin first (note the bearing washer under the sleeve)...

Attachment 20814

Put the razor on, then another bearing washer, then scale and pin as usual....

This is a fast simple solution to over-sized pivot holes, you can probably do without this but as the razor moves and loosens in the scales you can run into problems with the edge hitting the scales and/or wedge it is just way easier to just throw a fast sleeve in there and eliminate any of these problems before they arrise...

You have my razor that I am going to have to do this with. So thanks cause I was gonna ask sooner or later.:rock:

I know this is an old thread, but: I'm new to working with tubing this small and soft. Brake tubing is about as small as I work with and that's many times bigger and harder than small brass tubing. What did you use to cut the brass tube without making it out of round? I need to fix a worn out pivot hole in a razor and was directed to this thread as an option for fixing it.

Thanks!

I use a hack saw 24tpi and almost no pressure,,, then file it smooth

Thanks.

Wasn't sure if a 24tpi hack saw would be too aggressive for that tubing. I'm not familiar with how soft it is.

Jim I look for this display in the Hardware store and get everything from it :)

it is from K&S metals an found in many stores

hmm can't get the website to come up will try later

I use a utility knife/box cutter to cut the tubing. Just kinda roll tubing over flat surface, similar how a tubing cuter would work if a small enough one could be found.

For tubing and rod sizes, (copy paste from other post I did)

Here are some part numbers if you want to try online like Amazon or someplace.

If need brass tube for ovaled out pivot hole the following:
What I have still with labels:

part number 8126 3 pack sku 14121 18126 1/16 ID, 3/32 OD - it will slide into
part number 127 Single item sku 14121 10127 it will slide into
part number 128 Single item sku 14121 10128

Stock# 8125 3 pack 1/16 OUTSIDE Diameter if a need for that small

For brass rod
part number 8162 brass rod 3pack 12" long
part number 1162 5pack 36" long
I think 162 would be for a single 12", but I have never used/found it.

I would guess 3 pack part numbers have the '8' at the front of part number, and single item is 3 digit PN? So would suspect 129 would slide over 128 if you had that as a need.

By same logic, if they do single rod 1/16 rod, probably part number 162?

I found a tube from a cotton ear bud to be a perfect size for most over large pivot holes, i've used it works very well also being hard nylon wear dosen't seem to be an issue, fits snugly and easy to cut with a stanley knife.

Jamie.

I learned a trick to cut steel pins and small parts from an old master gunsmith. Lay/stick a piece of scotchtape on the bottom side of the pin and use a dremel cutoff wheel to cut the pin. If you go easy toward the end of the cut it ends just hanging on the tape. If you go too far it falls on the tool bench or floor stuck to the tape and is easy to find. I've had a chance to sleeve 1 restore so far following this guide in the stickies and used this method to cut the tube. Worked slick.
Hope this helps,
Karl

Old thread...worth bumping!
