OriginalPancake Posted April 14, 2021 Share Posted April 14, 2021 About 3 years ago I decided to start my 2x72 build. Life got in the way and several tracking issues with a treadmill motor I have up. Recently I said heck it and got the origin blade maker 3/4 Hp motor and vfd. Before I drill holes I want to make sure I'm doing it right.. I assume I want all the wheels aligned/ level with the drive wheel? And back from the grinder frame to establish good tension so the belt won't fall off? Thanks in advance Link to comment Share on other sites More sharing options...
Steve Sells Posted April 14, 2021 Share Posted April 14, 2021 3/4 Hp is very small, double that is recommended minimum Link to comment Share on other sites More sharing options...
ThomasPowers Posted April 14, 2021 Share Posted April 14, 2021 Most 2x72 grinders I have seen/used don't tension with the motor but with a spring loaded tension wheel. ++ on the larger motor. Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted April 14, 2021 Share Posted April 14, 2021 If you are talking about the V-belt tension, yes the pulley's must be aligned. Our KMG three speed grinder uses a 1 1/2 HP motor, I'm afraid a 3/4 HP motor will be way under powered like Steve said. Maybe a picture or two of your build will help clarify.

ThomasPowers Posted April 14, 2021 Share Posted April 14, 2021 Ah yes and the spring loaded belt tensioner is also shown in those pictures; thanks IronDragon FCW! Link to comment Share on other sites More sharing options...
