Alright guys after much dreaming I've started my grinder (HAWGER) project and will post pics when it's finished. However, being me I'm approaching it in a very unorthodox manner. A KMG or other name brand was not in the budget so I'm going to build one similar to the one featured on PurgatoryIronWorks youtube video. My intentions is to glue the belt around a 2" x 22.91" flywheel made by stacking, laminating and fastening mechanically 4 - 1/2" x 23.25" hardwood plywood circles. then attaching it to a bearinged shaft via flange, (possibly a 6 lug chevy truck axle) and running it at 200 rpm netting me 1200 sfpm (low, but safe) I'll run it in to the proper diameter by useing a wood lathe gouge to remove what is not needed while it is running.
so my question is this how consistent is the 2x72 belts in being actually 72 linear inches every time?
72" linear = 22.91" circumference
1725 rpm 1" pully to 8.625" pully = 200 shaft rpm
200rpm x 22.91 Dia x pi / 12 = 1200SFPM
