Reverse Boss Bevel Gears and Differential Meccano compatable

thingiverse

Frame is easier to use than trying to get Meccano metal strips to form a square. Shrug. No support required. Bevel gear grub screws are at a 30 degree angle. Used my portable drill to wear it in quickly. Suggestion, first run the grub screws in and check that all loose materials are removed to avoid splitting, then push the gear on to an axle and run the axle back and forth to loosen the fit if tight. The Tri-axle version requires 3 gears and 1 regular. It is louder and not as smooth as the round axle versions in my opinion. Put the nuts into the four interior corners with a little persuasion before assembling the differential. Send money, lots of it. https://youtu.be/5mlez7Cs_mE
