English is not my Mother tongue so bare with me . 
So I wanted to share my home made flat lap. I drew inspiration from many of your awesome threads . The Flywheel is 13" ,made it out 3/4" steel plate which I machined down to 6/8" .The axis is 2" and its attached to a 5 inch pulley .The motor powering this is a 1/4 hp Leeson single phase 1750 rpm,it's some what under powered but it should get the job down .I'm still hunting for a controller board for the motor.The motor has a 3 inch pulley to reduce some rpm's and get the flywheel down to 1000 rpm .The Flywheel has some screw holes to attach a 1/2" fastening ring that am hoping on experimenting later on with wet/dry sanding paper.
I ordered 12" diamond discs,grits 140/220/325 ,from Hisglassworks with magnetic backing .I made the wheel with a 1/2 arbor as I see a lot of 8" discs cheap on ebay and other sites. So hopefully in a time of need they might be a temporary substitute if I can't get the 12" ones in time, as they have a 2-3 week lead time.
I couldn't find locally a Coolant Hose so I made it out of some fish tank air hose and 17 feet of 10 gauge copper wire.Fastened it to the tip of a silicone cone then to the 5/8 hose that leads to the 2000 lph (520 gph) pump .
Well if you have any question please ask I'll answer them to the best of my abilities and up load more pictures . Further down are the pictures and link to a video ,Video is shaky sorry, of the machine.
