belt grinder build

Recommended Posts

Posted (edited)

2x72 3hp belt grinder

if my calculations are correct, it delivers about 6500 sfm at high speed.

Dayton 3 horse 1740 rpm single phase with pulley speed shift. 

3" & 6" contact wheels on the flat platen/slack swivel attachment - the platen is tube, so far the radius helps me to not gouge at the belt edge.

imported 14" contact wheel that works great imo.

 

throws down a spark shower, as i'd hoped

This looks great. Do you have better pictures of the platen so I can better understand it?

instead of angle iron etc 

i used a 2" square tube -

so the actual flat of the platen is just about 1-1/2" wide, and there's about 1/4" of radius on both sides where the belt can give a little

finish-welded the stand, painted & hard-wired a 2 pole 3hp rated switch.

and corrected an ugly weld on the front foot :{}

Sweet build! Lol, I'm hoping this fall I'll get a work study in the metal shop at college, if I do I plan on building a new grinder with their tools!!
