This is just perfection.!
Couple of questions, what does "then CA glue it to the backer " mean exactly??
What is the final size of your acrylic plug? thickness = 4.4mm OD=?
Are your plugs tapered? They appear to have a taper in the pics.
looks like an extremely tight fit, how did you seal it exactly? Around the OD?
Sorry to bombard you with all the questions, but I am obviously trying to do this, and I want it perfect just as yours is!!
Thank you in advance!
