Motorized Grain Mill shaft support

[cpatel479]

Hey guys. I'm having an issue with motorizing my grain mill. I am using a 12" pulley and a 1.5" pulley. I have to use a shaft extension because the 12' pulley pushes against the hopper without it. The issue I am having is that because of the length of the shaft extension and the weight of the 12" pulley, the roller connected to the shaft wobbles. How can I support the shaft near the 12" pulley? here is a picture of what I have so far.

Replace the "wood" base with something longer, then install a bearing block out near the big wheel. Mcmaster-Carr sells lots of different ones...

I extended the shaft on mine as well. As day_trippr pointed out, you will need to modify the base. Here is a link to my build, hope it helps.

That sound expensive. Why not change up your hopper? Or slightly smaller sheave? I have a similar setup I’m currently building. I used a 10” sheave - this was enough for the clearance required.

Damnit - sorry for grave digging...
