ive got a 35ml one you can borrow...... its brand new never used & ive got a 8ml one that i was given for free to practice with. just go to a glass place and ask for a couple of scrap bits of glass and do a few practice runs to get use to drilling glass...... your most welcome to borrow them... and if you want to pay the $5 bucks courier fees each way i can loan you a drill as well......
