Thread: Tighten bulleye hinge pin

I have a nice koorat razor and the hinge pin is a little loose. I tried tapping with my hammer and didn't feel like it helped. Is a bull eyes rivot different?

Sure doesn't look like brass. I'm not sure but if it's nickle that would be harder so then take more tapping. Just a guess on my part. Beautiful razor

I do not know how they pin their razors specifically, but a standard bullseye is just a different collar or washer on the surface, the pins are all the same, so it should tighten with tappingjust like any other. Do not hit harder, just hit it more. Essentially you are tapping down the edge. The end of the pin forms over like a mushroom and you tap slightly off centre all the way around.

Hum really slightly off center, I always tried to hit dead center, maybe that's my problem.

In actual practice, you're going to be making taps randomly all over the surface. But if you use a proper rounded jeweler's hammer, you can try to concentrate your taps around the edges and watch the dome mushroom over if you're doing it right. I don't know it it's "correct" technique-wise, but I have gradually stumbled on a hammering technique that works for me. Holding the hammer head pretty close to the razor, I start sort of speed-tapping in a real rat-a-tat-tat motion as I slowly tilt the razor around on the back side of the pin resting on my mini-anvil to get it doming over evenly all the way around on both sides. I also keep changing the blade position to make sure it's tight at all positions, especially in the 90 and 180 degree shaving and stropping positions. Flip over and repeat until tight all over. I hope this helps.

Nice razor-don't beat it too hard!

If it is off center to correct that tap in the direction you want the blade to move to. If it's off to the left tap on the right. Tap is key, 1000 taps rather than 100 hits.

I've tightened the same pins on my Korrat, they are pretty straight forward only one slight problem you will encounter the head of the pin will slightly mushroom more than it did originally, so after you've completed this fix my advice would be is to punch a hole in a strip of masking tape slightly larger than your pin head cover the washers leaving your pinhead exposed, now using 400 grit then 1000 grit and finally a little metal polish clean the head of your pin up.
