/diy/ - Do It Yourself

>>1548323

said fuck it and built a belt grinder for free

i had 2 old 1/2 hp 1750 rpm electric psc motors, i combined the parts into one fully working unit with drive pulley. i hammered the armature off the unused shaft, ground the fins off, and key-wayed it to the end of the shaft of the new fully operational motor, as the drive pulley.

then i took 2 pieces of flatbar, and essentially made a pair of scissors with one idler pulley being on the same shaft as the pivot.

i mounted the third and final pulley, on the end of the top flat bar.

i drilled and tapped the bottom flat bar through and to the case of the motor

i put a stronk spring over some ready rod and used the "handles end" of the flat bar/pulley scissor contraption to make the tensioner adjustment

i made an adjustable platen for it as well

the 2 idler pulleys i got out of a 95 gmc 2500 parts truck i got out back, metal pulleys with bearings and spacer bushings

oh and i stretched a dirt bike innertube over all the pulleys so they got some rubber on em

things a fucking beaut when i fix my camera/get a new phone ill take pics, pic related for now
