Thread: what size pin holes in acrylic ?

Hi guy's, I want to make some scales out of acrylic. I looked around the forum for the info I want, but didn't quite find what I was looking for.

I don't have my rod for making the pins yet, but I'm thinking of using 1/16 rod, something silver looking.

I'm wondering if I should make 1/16 holes, or something a tad bigger just to make sure that the expansion of the rod in the hole when peening won't make the scales crack. I don't know how important or negligible this expansion is when peeining, since it will be my first time doing it.

Thanks in advance for the info.

Glenn.

If you go for 1/16 rod then you need a pin hole that is slightly larger as the rod's diameter might vary slightly, and you need to have some slack for the scales to adjust when pining.

Personally I use a 5/64 on all my scales

Awesome guys, that answers my question perfectly.

Same here. Perfect size.

As we're being slowly overtaken by the EU I couldn't find imperial bits in the UK, but 2mm works great as well.
