Yesterdays after hours project, an idea thats been rattling around my empty head for a while now.
Step 2 is to add a motor and worm drive gearbox to the top. Already have that, its a small DC motor off a metering auger, so slow, infinitely adjustable and precise. One of the perks of farming, you always have junk and parts like this lying around. Maybe thats why we dont make any money!

Looks good! Will the urethane wheels melt?

[JayWal]

If you weld too close, maybe. But theyre more hard plastic, the yellow is a hard rubber and theres a steel bearing inside. Theyre actually for a potato digger and they can carry a pretty serious load, they run in dirt all the time so theyre not designed for hobby stuff. If they do melt i can get all steel ones too. But i dont have spare steel ones kicking around since the bearings themselves are replaceable on the steel ones. The wheel itself lasts forever.
