I have been asked to make some wine stoppers and the person has asked for them to be made out of the acrylic that Woodcraft sells - https://www.woodcraft.com/products/a...-2-x-1-1-2-x-6

I will be using Ruth Niles stainless stoppers.

Do you guys just tap the acrylic? If so, do you just use the niles mandrel for the tapping or do you use a regular tap?
Do you use brass inserts? If so, which one?

Thanks
Ricc
