Thread: Proper Sized Hole ??

I purchased a very inexpensive razor (delivered for $15 from SRP) so that I could experiment with 'Cleaning up' a blade and trying my hand at making scales and pinning them.

After removing the pins, I found that the hole through the blade appeared to be elongated. However, by looking through the opening, it appeared to be a circle. However, a 5/64th drill bit wobbles in the opening. More from toe to heal, then from spine to edge. so it is elongated.

I've checked out a the information about how to 're-build' the hole using several different options.

My question is this: If the pin is 1/16th of an inch, when I re-drill the opening, what size drill bit should I use?

Sleeving an oversized pivot - Straight Razor Place Wiki

I drill my pivot hole out to the outside diameter of my sleeve, which has an inside diameter of 1/16". It is probably not necessary to fill in the hole and redrill it.

edit: Also, when I measure the sleeve I lay the razor flat on the table, put the sleeve in the pivot hole, and mark the tube with a pencil flat against the tang. I use a razor saw with a miter-jig to cut the tubing for the sleeve. It gives a nice straight cut. You can find them at any hobby shop, especially at ones with train stuff.

Roy, if it's only slightly oversized there's not a lot of need to mess around with trying to drill it.
Just pin it, and it will be fine.

Thanks Eric!

You have always been so extremely helpful to me! I truly appreciate all that you've done to 'guide' me during my very first experiences with SRShaving and you still take the time to help me as I progress! Thank you my Friend!

I might be being 'anal' but I guess I got it from father who's proudest accomplishment was becoming a Machinist! He was 'Always' a stickler about clearances!

With that said, I do find the hole 'excessive' and I will be using J-B Weld to seal it and then re-drill.

Going back to the 'anal' thing, if the pin is exactly 1/16' and the hole is exactly 1'16" then something has to give! I would imagine that the drill bit would 'probably' flex enough that the hole would be somewhat larger. With that said, if by chance the specifications were exactly the same, I know how to make the two be able to join. However, they would then be seized. There has to be some kind of 'Clearance!'

The 5/64" in drill bit is the only one that I have on hand that is slightly larger than 1/16". I do have access to 'Letter' and 'Number' drill bits. I 'Think' that the 5/64" would be OK, but I'm not sure!

Glen said something in the Wiki about how the razors had been pivoting on a 1/16" pin for 100 years and anything closer would probably last another 100 years. I would just like to know how much clearance to start the next 100 years off with!

Eric! Again; Thank you!

Definitely use the 5/64. If you make scales use it for those too. There needs to be a little bit of clearance there. I cracked several sets of scales because I was drilling them to 1/16. One day while whining about it in the chat, Glen informed me that I was drilling the holes too small. I haven't had a problem since.

Good luck!

Thanks Eric!

That's the ('second opinion') that I was looking for! I was pretty sure that the 5/64 would be OK for the Blade, but I'm glad that you mentioned the same size for the Scales! I would have used 1/16!

A very dear friend of mine does some nice wood working and has some Black Walnut that he's going to use to make the scales for me. I designed the scales (I hope it works)! My friend is going to use Oak for the spacer. It should look nice!

As you can see it's a Joint Project with neither of us having done either before! So far, it's been a very interesting project!

Thanks again!
