Hart scales

[kmlavoy]

Is there any reason that you couldn't use Hart replacement scales on a vintage blade, assuming the size is pretty similar? I like the hex nut assembly for cleaning around the pin. I'm just kind of curious if they have a proprietary hole size that might not work with vintage blades.

Follow up question: does anyone know how long a Hart blade is?

You could use it on a vintage razor, the hole size for the Hart scales are bigger to accommodate the hex nut. Many older blades have larger holes.

I don't know the actual size of the Hart blade.

I looked into getting folding knife pivots for some Gold Dollars, but wasn't sure how easy it is to drill into hardened steel.

Larger holes on a vintage razor are usually oblong from wear. You will need to drill it out round to the proper size. Too large and you can use a brass tube to fill the hole in the razors tang.

The razors steel is usually very hard. It dulled the bits I used. I counted it a small price to pay for a properly restored vintage razor that closes firmly.

P.S.
I usually make my own scales. It takes longer, but is cheaper and more satisfying. Actually polished bone looks great!

Actually, a lot of them pre-1900 were hot-punched, not drilled. Hence the range of sizes depending on the tool used to do the punching.

+1. The wear on tempered steel against a brass pin I don't believe would happen since a file won't touch tempered steel.

The Hart Hole size is 3/16". On a lot of old razors the tang would be too narrow. You would also, most likely, need a carbide bit to get through it as well.

The origional spec. on a Hart Blade is 3.6" from the center of the hole to the end of the blade.

I hope this helps.

Maybe you are right and they were hot punched. Most of the oblong ones WERE pre 1900 and the holes were wider on one side and narrower on the other.
