Well, I broke the bone scale of my Peaso at the pivot pin. I'd like to try to repair it, but thought it would be wise to run the tentative plan by the voices of experience:
Glue the broken scale
Reinforce the inner sides of the scales by gluing on shim brass or large bearing washers
Sleeve the pin holes for more strength
Add a third pin just because
Any constructive criticisms?
And is there anyone out there who will sell me a small quantity of pins, washers and shim stock?
Once its cracked at the pivot hole I think its pretty much a goner, and it looks like there multiple cracks coming away from that hole too.
A brass liner is probably your best bet, but I wouldnt be too confident that it will last.

I sent you a PM about the pins.
One thing you could do is hollow out the inside of the scale and fill it with epoxy. This would also fill the back side of the crack and the pin hole. After it dries re drill the pin hole and re pin it. Ive done it before. Some hold and some dont.
Looking at how it's spider webbing around the pin I'd say it's probably a done deal :( What do the entire scales look like? Are they fancy and worth the effort or would you be better off replacing them? :gl:
Thanks for the PM, Simpleman, that's exactly what I need. And shipping is only a stamp.
Was thinking to try epoxy and brass liners and sleeved pins. But the consensus seems to be that it's a goner. Well, I'll figure out what to replace them with.
Catrentshaving, they're just plain bone, but I liked them.
No Problem.
I look at it like this. Try to fix it and youll be out a few bucks and some time. If it works cool if not you dont loose much.
Whoa,,,, Bone can sometimes be fixed it allows way better adhesion with Epoxy and Glues then the Celluloid, and Bakelite compounds do...
It is worth trying, you upped you chances of success quite a bit now :)
Edit: are you sure it's bone??? that looks more Celluloid in the pic then Bone, but pics can deceive us quite easily...
My apologies...I should read and maybe reread...lol. The pics look as though they're plastic or celluloid and that's what made me woder if worth saving them. As others have said, you've really got nothing to lose in trying. As Glen said try an epoxy...I've tried it with horn and it did work.
I've looked at it with a magnifying glass and compared it to some bone-handled cutlery and figured that's what it was, but I wouldn't be my life on it.
Kicking myself because I shot three deer this past season, and with each one I thought about saving a leg bone, but didn't.
Is any particular brand of epoxy better than others for this?
Hi, in my experience most of the epoxies work the same. However, I'd go for the replacement since there are some fine replacement scales out there in classicshaving.com that are inexpensive (DOVO) and they already have the drilled holes in the pivot section and come with silver pins. Should be a 30 minute work altogether!!!! (done that a couple of times and worked like a charm: one bone and one plastic)
That seemed like a great idea until I tried to order them. Every one is "unavailable for ordering at this time". You guys must be breaking a lot of razors. ;)
Probably a good thing as they don't fit every razor...

With any pre-made scales you'll generally do well with 4/8-6/8 hollow ground razors; especially your run of the mill round point like an off-the-shelf dovo. When you start looking at anything with a heavy grind, a bit natural smile, or a larger blade, they frequently won't work.
Edit #1 - Oh, and if you do go with the pre-made replacement scales, I can't recommend the pins that come with them. The preformed side just doesn't look right. The cost of a brass rod and some washers is nothing, and the results are usually FAR superior.
Edit #2 - Those really don't look like bone. I'd bet almost anything they're just bone colored plastic. In fact, the pin on there looks just like the pins I was talking about that come with Dovo replacement scales.
Put a hot pin to the inside and you'll know if it's bone or plastic.
And there's always the next hunting season, or you can grab a bone from the pet shop. Though everybody says it's really stinky to work with.

You do not want to glue the scales to the steel but glue

I once fixed a Kirby Vacuum with layers of aluminum foil
and epoxy. Kids slurped up a bag of marbles and the
housing was cracked. Being poor I repaired it well
enough to get another ten years out of it. You might be able to
do the same thing. Multiple, very thin layers of foil and epoxy building it
up on the outside bit by bit. If done with care it might look
like it belongs.
Replacement scales might be in order. Scan the sponsors
web sites. I have seen scales of various quality
levels including fancy wood, bone and horn. The
inexpensive plastic ones are very serviceable.
The distance between pins is indeed longer than on my other razor, a Dovo Bismarck, so I scrounged a piece of purple heart to rip into 1/8" slabs, and ordered pins and washers. I like the idea of brass liners and sleeved pins for some reason, so I'll see if I can find shim stock and tubing as well. If I'm not embarrassed by the results I'll post a pic. And perhaps try again with bone.
Interesting aside: As I was typing this, a mink ran through the snow past my window with a red squirrel in its mouth.
The problem seems to have been that the original pivot pin was too tight. As the razor is opened, I can see the scales spreading and tightening, and something had to give.
Thanks for all the advice and sources. Hope this doesn't turn into a new hobby, that's all I need.

Nope, that is the way they work,,, The tang is at an angle hence the wedge being a wedge and not a spacer...
Over-tightening the pins can crack the scales by tightening the solid head that we see in your pic...These pins (What VeeDub pointed out) tighten form the back side only most Vintage pins tighten from both sides...
The scales do "Flex" and should flex otherwise you built a knife :)
Be very careful when using Liners as most people will unbalance the razor..
There is a ton of info about how to build them in the Workshop Sticky...
I think I've read almost all the workshop stickies. The one about wedges alone probably saved the skin on my fingertips.
Anyone got a source for just a few micro-fasteners? I'd like to use them for fitting, but the only places I can find online sell them in big lots.
