Grinder V 4.30 B

Grinder V 4.30. B

This is V 4.30 with bearings added.
One problem I noticed with long term use (2 years) of the original grinder V 2.0 from rmcht was that even though the rubbing surfaces were kept lubed with lithium grease, was that it was wearing where the gears rubbed on the body creating more slack and backlash. Using bearings would only leave the teeth on the gears to wear out meaning it would last much much longer.
The bearings used are 608Z and 606ZZ bearings, two of each.
The gears, axle shafts and burr wheels are modified for this version only.
It uses the same drawer and lid as V 4.30

A revised Large Burr wheel is included. I found that the triangle shaped teeth on the original did not grab the "material" very well so redesigned it to be more efficient. This burr is only for the bearing model.

Opps. Darn. I replaced the shafts with the proper length. They need to be 63mm long.
