Thread: Just to see what others think.

When you have a 3 pin razor and when opening it it is tight at the hinge pin. then when you close it it get's loose just before you close and you have to guide it back in the scales. I believe this is caused by the second pin the spacer in between the scales being to wide. What do ya'll think.

Or the wedge is too thin

I'm not sure how it could be tight when opening but loose when closing. That should be the same position, but going the opposite way. Makes me think maybe the hinge pin is bent or the pivot hole is enlarged; something about the positioning when opening vs closing must be different. Or I'm misreading the OP.

I may have not explained it correctly. when you open it it's a little loose but when it's at a 90 degree it tightens up but when you close you need to guide it to keep it from hitting the scales.

Look at the scales

That small amount that is past the pivot pin..

If they are curved inward, and touch the tang during rotation this will cause uneven tension

This spot




actually just looking through that gap will tell you quite a bit about contact points, simp[ly hold the razor up and observe the rotation from the top and bottom of the razor with a bright light behind the pivot and look for contact points

I think Glen and Outback Mike are both on the thoughts I was having. The size and taper of the wedge in relationship to the taper on the tang of the razor is what makes the sales flex and move to give fluid tension on the pivot of the razor as it moves through it's rotation. Glen's point that if the part of the scales sticking past the pivot not being straight also having an effect on the tension.
Short answer. If you look at the end and everything looks ok check the wedge. The length of the spacer at the third pin should be the same as the fat end of the wedge or the thick part of the tang.
