I just completed a new 2x72 grinder. I used the plans from Dan Comeau and found that the machine works quite well. The following material was used:
2x2x.250 square tubing
1.750x1.750x.250 square tubing
.500 alum. for the platen holder
Set of 4 roller from Oregon Blade Maker
8x14x .250 steel plate for base
2hp 3450 motor single phase
Assorted nut and bolts
It was built as per plans but I would suggest using fine thread for the top roller adjuster, as the adjustment is very sensitive with a course thread. The machine runs very smoothly and has no sign of vibration. In comparison to my friends grinder it quit a bit quieter. Most of the cost was taken up by the motor and rollers, I have a little less than $300.00 for the total job.
