Resolving a Cracked Scale Issue

Ok, so I've been restoring this Plum Worcester razor.

Attachment 130162 Attachment 130161

I'd cracked the scales at the pivot when I unpinned them but I glued it using wood glue and left it in a clamp until I was ready to polish them up anyway. It worked fine, except that they split again while I was re-pinning—not due to carelessness but from the pressure of the tightening pin.

Attachment 130159 Attachment 130160

In my mind I have several option and, really, I'm just trying to ascertain which is the best route to go down:

1. Unpin again, glue again (perhaps differently) re-pin again (still with the risk of them splitting open)

2. Attempt to glue them while pinned (somehow...?)

3. Find something to reinforce the inside of the scales with and glue it all together (any suggestions for the best way to go about this?)

4. Buy new scales

5. Use razor in current condition—yeah, the scales are still rather loose but they're wide enough that they're held in position by my fingers while I shave and done flop about dangerously...they're not tight, and technically they're still broken but...does it matter??

What do you guys think? I'd like the razor to be fixed up properly but perhaps it's a trivial matter that I shouldn't worry about.

If it were me I would rescale them due to the length of the crack. However that is just me. To answer your question if you really wanted to keep the scales epoxy resin. If you reinforced them with epoxy resin after they have been glued together, they more than likely will not crack. I have only done this once to an old wade and butcher buffalo horn set. They were original, but you could tell they had resin on them. Glue them together and dip them in an epoxy resin. Let dry for a day or two and sand away. Good luck.

I think I know someone who might have some epoxy resin lying about...

I'll give that a go and think about a re-scale if it doesn't work.

If you want to go historical, there were a lot of creative repairs that were done in the period. Some things I've seen are wrapping a band of brass around the crack or cutting the end off the scales, making a new tip out of horn, and pinning them together with a brass liner.

Do not think that can be repaired at this point,JMO good luck.

That's a pretty cool idea. Maybe I'll think of something similar.

Here's the band type I was talking about: Attachment 130410

And here's a splice repair: Attachment 130411

That is a great old splice repair. Nicely shaved piece of brass just underneath, pins all over the place. Gives that razor a frankenstein look to it. Great pic's scienceGuy.

I have also had this problem.Here is my solution:
Go to any hobby or hardware store (Hobby lobby is a good choice).
buy some brass tubing in 1/16 Id..it is 3/32 od.
drill the pin hole out to 3/32
cut the tubing down using a dremmel cut off and
glue the tubing in the hole using super glue
also glue a thin washer to the inside of the scale and you have it...
I also use this method on Ivory from the start before pinning it, this allows you to pin it tight without stressing the scale material.
This method is a lot of trouble but it does solve the problem.
(The only problem is you must use a washer under the pin on the outside to hide the tubing. Not usual on a ivory scale.)

I have a single celluloid scale though I don't know if it's the same side. It's not very exciting though, it it.

I like the brass banding, though that might not work because the crack's at the pivot. Unless I found some really thin brass and balanced the other side of the tang with washers...

Brass tubing is a good idea for future rescaling of delicate scales, too.

So I was going to glue the crack, buy some thin brass strips and bond them to the inside of the scales, then I had an idea. I remembered that I had a whole load of waxed cotton from wrapping my kamisori so I did this on the off chance that it might keep the crack closed:

Attachment 132946

The glue seemed to hold this time, anyway...

Attachment 132947

...I used three washers on each side to balance the scales; it took quite a bit of hammering but I'm pretty happy with the tightness now.

Tomorrow I'll try and hone it up, at last!

I was able to save a cracked scale by re-pinning but I glued the really clean scale with slow setting CA. To reduce the chance of splitting after, I used a slight 30 degree Dremel tool point to make a countersink in the renewed scale before pinning. that allowed some fattening of the pin without cracking the scale. I used 100 proof alcohol to clean the crack and pin hole. It can cause a problem with some materials. So a very strong degreasing cleaner and good water rinses after would do.
