Description
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.

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
