This is my own design of a berd air bending and drilling jig, I have included several pictures to show how it is used, The holes in the tube are at 45 degrees the reason for this was because I found the normal straight drilled tubes didn't cool fine points to well and the nozzle heat would spoil the finish, The aluminium tube used was K & S 8101 Round Aluminium Tube (Pack of 3) 3/32" Dia x0.014" Wall and can be found here, I used a 1mm drill bit in a pin vice / chuck
NOTE: You may need to use a little wet and dry to sand the bender centre pin to a nice fit or ream the hole, Use a 3mm x 10mm cap head screw to hold the roller on The holes on the 45 degree jig come out at the opposite side off the jig due to the angle.
28-04-19 Added two new stl files a new 45 degree drilling jig with a slight error correction from the first one and, A straight drilling jig for those who would prefer the holes straight, Also added a little notch to the side of the jigs inline with one of the holes to help line it up
