OK so its been awhile scene i posted on here and well i need a little help.
so here goes.. after grinding my last 3 batches by hand. i figured that i need to motorize my ugly corona mill.. so i found an old vacuum motor. 12 amp 10,000 rpm ( from what i read on the dyson dc14 motor).. its a little to fast. so i messed around with a pulley calculator and figured that i need 2 sets of pulleys 2- 2.25 inch vbelt and 2 12 inch vbelt both 1/2 inch bore. by doing that i can get it down to about 324 rpm.
my question is would that be enough? or should i go for an even greater reduction. and if that is enough where is a good place to get the big pulleys? as ive found the smaller ones on amazon for 4 bucks
thanks for any help
