Excellent video, look forward to that next video. If you would, Will you show a diagram of how the differential screw works on the inside of that hub ? I would very much appreciate that , just a little drawing on the white board. Thanks
They could be, or should be, but on my lathe I can't cut metric threads (yet). So IIRC I cut them to 3/4" x 20tpi. Which is pretty much 19 x 2.0. Good question. Thanks for watching.
On mine they are M18 by 1.5 mm. I bought lockable precision nuts from China instead of making them, just made 12 similar arbors. The nuts are 5$ each very nicely made. The lockable nuts makes it possible to run the grinding disks in reverse without the wheel coming loose. I intend to modify my D-bit grinder with a reversible VFD. Stefan Gotteswinter did this differently by putting in a key slot. Considered this but it seemed easier to just buy the nuts.
Lock nuts that you bought from china are they K-type or R-type? K-type are double price? There is also F-types for sale! R-type and F-type looks similar! @@erikisberg3886
I will. Promise! Been a little crazy around here for a while. In the meantime, I would suggest checking out Joe Piezynski's ru-vid.com/show-UCpp6lgdc_XO_FZYJppaFa5w page for some excellent tips on single point threading.
