a question of technique?

[uppercanada]

When tightening loose pivot pins ( I tried it on a not great razor first) I had a problem of knocking the blade off center. Should one use multiple small wedges to establish the position of the blade or once removed is the blade then going to... or have the potential to drift off to one side? Is it all in the technique of hammering the pin. what am I missing?
I am using a small hammer from my mitutoyo gauge repair set with next to nothing other than the weight of the hammer as far as force. tiny little taps.

any advice?

You might still be hitting too hard. Use a Ball Pein hammer and tap so lightly that if you tapped your fingernail on a sensitive area it would not hurt.

I use a 4 oz ball peen hammer and it works great.
as far as how hard you tap, I find that lifting the hammer ~.5" above the pin and using its own weight to do the job works fine.
It take more than a few taps to get the job done so be patient.

Aside from adhering to the above, also continually alternate peening on opposite sides of the scales to keep it balanced. Do 10-15 taps on one side and then go to the other side.

Thanks, I'll give all those things a try this weekend.

I tend to make one rivit head in the vise. Then after I assemble the different bits and pieces, I set the unfinished head very lightly. Then like Utopian, I tend to alternate sides to snug the pin up.

good luck, and let us know how it works for you!
cheers!

Tap, tap, tappity tap. Lots and lots of little taps.
If you hit too hard you can bend the pin.

That's why I like micro fasteners but when I do pin I use a 2oz ball pien hammer and something like a million taps....lol....Did I mention I lke the micro fasteners.

+1 to the above, small taps and check often.
