mach1soldier Posted March 12, 2015 Share Posted March 12, 2015 So here is the deal. I have a case pro 100, and two big electric motors. I have a bunch of pulleys and pillow blocks. Even some metal for the shafts. The motors are 1125 rpm. One is 1/4 horsepower 110v and the other is 1/8 horsepowder at 1150 rpm, also 110v. My idea is to put a 1.5 inch pulley on the motor, run it to a intermediate shaft with a 10 inch pulley. Then another small 1.5 inch pulley with a belt running to a 10 inch pulley on a shaft. At the end of the shaft I will put the arm to push the case pro back and forth. Anyone ever done something like this? I looked into the air method and buying a different motor but I have 90% of the things I need already. Possible concerns: Belt slip from case pro needing to much force. Guessing I need around 20 RPM on the pulley running the case pro. Does this seem right? I think that's the same the ponsen warren autodrive runs. I can go slower if it would work better but the pulley size starts getting a little crazy for mounting purposes after 12 inches. Thoughts? Link to comment Share on other sites More sharing options...
jmorris Posted March 12, 2015 Share Posted March 12, 2015 (edited) I was in the same boat when I bult my 100 lb wet tumbler. I had all the pullys and pillow blocks as well but wound up "winning" a gear motor off of eBay for $35, not free but cheap enough, much faster build, more compact and less to go wrong.

mach1soldier Posted March 12, 2015 Author Share Posted March 12, 2015 If you don't mind me asking, what are the specs on the motor you bought? I wouldn't mind spending 100 bucks or less on one. Link to comment Share on other sites More sharing options...
Rob Tompkins Posted March 12, 2015 Share Posted March 12, 2015 On the face of it, the belts could possibly act as a "clutch" so that a jam in the CasePro would not break anything. I could see the need for frequent tension adjustments as the belts wear / streach and the weather changes 9het and humidity). If you have parts and want to expeirement, go for it.

Mine was used but free, try eBay. Info is in this thread. http://www.brianenos.com/forums/index.php?showtopic=99460&hl=%2Bcasepro+%2Bmotor#entry1137058 Link to comment Share on other sites More sharing options...
BeerBaron Posted March 16, 2015 Share Posted March 16, 2015 It might be worth considering a tensioner setup for the belts. Just need a back plate with an idler pulley on one side of the belt and the tensioner on the other. Link to comment Share on other sites More sharing options...
