Thread: Hinge pin hole

first post whats the best way to fix this eeg shaped hinge pin hole

This one one way http://straightrazorpalace.com/works...zed-pivot.html . Do a forum search "fix pivot hole" and you get a many more.

I usually sleeve them, but I have seen people fill the hole with JB Weld and redrill the hole.

I use a Dremel grinding bit or tungsten bit to drill the hole round then use brass tubes to fill the hole to suit
i also spread the tube with a centre punch to lock the tubes in place

Ok guys never thought of sleeving ...I was going to try ultrasonic welding since i have access to one .but I think sleeving I could do at home.thanks alot

I am not a welder but be very careful with creating too much heat in a blade as it ruins the temper of the blade. Anything the builds heat in a blade is potentially harmful to it.

Sleeve it, peen with brass rod and drill or JB weld. They all work, peened brass rod and drill is best, JB the easiest. JB holds up well, there really is no pressure on the pin and hole, rust is the enemy.

You could JB weld in a brass sleeve using a 1/16 drill in a drill press to keep 90 degree to the tang, while it hardens.

Haven’t tried this… next time.

Many holes are twice the size of the pin. I just miked up a few Torreys I am working on, one is .095 and another in .125. I have no intention of sleeving either. I don't think you'll notice it once it's pinned up. Just make sure the wedge is not too close to the blade when closed so if it slips a little south it will not hit the wedge. Pictures can be deceiving but your tang hole looks OK. My vote is leave it as is.
Good luck and enjoy your project.

I have to agree

We basically have created the issue of the Point hitting the Wedge as restorers by closing the tolerance gap between the two in our builds.. This isn't a bad thing, but keep it in mind when trying to get tighter tolerances one sometimes creates different issues

I have never drilled a pivot hole out, I have a few different sizes of brass tubing on the bench they all fit inside each other, if the smallest tube 1/16 ID 1/8 OD doesn't fit inside the hole, then it really doesn't need a sleeve JMHO and a few restored razors..

Leaving just a tiny bit of slop in the pivot many times has been a very helpful thing in a build,,,

That sounds like good news to me ...the pin that was in it was bent and only pinged on one side our pulled threw so to speak..ill leave it alone and concentrate on polishing
