Looks good, it is one of the few home built grinders that I have seen with bearings at the ends of the shaft. At least in my eyes, a much better engineering solution than relying entirely on the concentricity and rigidity of the shaft to keep everything running true. In fairness, it does make changing wheels a bit more difficult, but I see that as a fair trade.

Yes I agree, I built mine with central bearings, it was quite tricky to balance all the expanding drums up.

Tell us about the plastic hoods and trays ... What is the material and how are the joints bonded together?

leviathan21 Looks like a simple, yet functional machine! I would suggest eliminating much of the space in the middle by moving the inner bearings closer together. You may even be able to eliminate one of the inner bearings. Then you can move the splash trays & hoods closer together so that the outer bearings are outside the wet zone. This will also give you more space between wheels (you'd have to resize the spacers between wheels). This may require narrower bearing riser blocks. Lynn
