i have tried and cut 3 blocks now, 8cm by 4 cm by 1/4" thick (srry for using imperial and metric side by side but what the hey..) and i have failed miserably. im using normal wood drillbits that can cut the copper, and they slip slide around.... the template im using is perfect, and i start off by glueing it on, punching the marks on, then when i get to drilling the first divets onto the copper it doesnt go on exactly perfect, then with the 5.5 ~ 6 millimetre bit it slides around and sometimes is off by a whole mm. do all drill presses do this and its my bad handywork, or is there a *special method* ?
even flaming me with an idea would be good
thnx
