I had some difficulties to get the wade screw ready properly. I tried the tap-method but was not successful so I decided to try the teeth version. This "thing" will show a method to get a desired amount of teeth into the bolt and how to divide the surface of this screw into exactly same sized teeth.
You will find all about the wade extruder here:
...and here on Thingiverse:
Can actually also be used on other similar extruder designs.
- Print the PDF file for 16 divisions (this number works fine for me...)
- Glue onto thick piece of cardboard
- Cut disc out and make centric hole with Ã˜ 8mm
Wade Screw (M8 screw or piece of threaded rod can be used):
- Take your screw and mark the position where theets are desired on the screw
- Screw the disc you made on one end and secure with nut
- Mount into your drill press
- 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.
- Fix a wire on the drill press to point to one of the divisions on your disc (pay attention that it is not loose!)
- 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
- After first cut, push table off the screw and turn (by hand) the drill chuck until it lines up with the next division
- 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.
