You will find all about the wade extruder here:
...and here on Thingiverse:
Can actually also be used on other similar extruder designs.

That depends on your extruder. You have to measure the needed lenght for your kind of extruder aswell as the exact position for the teeth to be cut at... you might want to check also my newer design of making hobbed bolts here: http://www.thingiverse.com/thi...

1. Print the PDF file for 16 divisions (this number works fine for me...)
2. Glue onto thick piece of cardboard
3. Cut disc out and make centric hole with Ã˜ 8mm
Wade Screw (M8 screw or piece of threaded rod can be used):
1. Take your screw and mark the position where theets are desired on the screw
2. Screw the disc you made on one end and secure with nut
3. Mount into your drill press
4. Fix your dremel onto the table of the drill press
this is a bit tricky.. I did it by clamping it to some support jigs. I leave the table of the drill press lose (not screwed in position) hanging on lowest level. like this I can centre the dremel once on my wade-screw and each time I pull the table to the screw it will hit the same position.
5. Fix a wire on the drill press to point to one of the divisions on your disc (pay attention that it is not loose!)
6. Start the dremel and pull table to the screw. Move drill chuck up and down a bit to get the teeth all over the desired area
7. After first cut, push table off the screw and turn (by hand) the drill chuck until it lines up with the next division
8. Repeat step 6 & 7 until you have cut all teeth.
Please mind: This screw design need well tightened nuts because it tries to unscrew itself out of the extruder. Use two nuts or a locknut to fix it in your extruder.
