Yup. Very well. I like to use a “thick” formulation for the method suggested. It is very handy to use an accelerator spray to instantly set the blob of cyano as you hold the stick. This is the exact brand I use and like. https://www.amazon.com/FastCap-2P-1...t=&hvlocphy=9033356&hvtargid=pla-569503655709 Denis
The draft is usually expressed as an angle. I like 2 degrees or even 4 degrees. More is better. For something 5 mm thick that translates to 1/3 mm offset for 4 deg. So it doesn’t take much. It is all taken off of one side. You could scribe a line 1/2 mm from the edge and file to it.
