glass joint taper?

Anyone know what the angle, either total or from center line, is on 14mm and 18mm joints? I want to see if i can find some stones to regrind some i have that rock. Or I'll make some if i can't find any, maybe there's a market. I've worked in shops where i ground glass, so i know it's not overly difficult to do.

You might have better luck asking this question on an actual glassblowers section. I am not sure if they have dedicated a section to that on this forum yet, but there are some great sections on glassblowing information on Tokecity.com forums where you could possibly get some really good answers to this.

Thanks man I'll check it out. Kinda figured there would be one or two glass blowers in here..

Ya you would think so, there probably is but they are not as active on this site. You could also check out boromarkets forums, that may help you out as well. Good luck!
