Conversions seem to be my new hobby and I am in my element when I am in the middle of one. This conversion was a lot of fun and got my brain juices flowing.
Anyway, my saw motor threw a shoe and since I am not a machinist I chose to replace instead of trying to repair. At some point in time the off pulley end bearing had seized and spun on the shaft and the person that repaired it did not do anything to repair the shaft so it was just flopping around inside the bearing. Worked for a while but eventually the shaft wore down enough so the armature was hitting the thingie (stator ?) on the inside of the case making it not go round and round.
I went to Habitat for Humanities and missed two motors by five minutes. Another man was there getting ready to load a compressor and pump that he had paid $25 for. Long story short there was a tread mill there that I opened up and saw a one horse motor just sitting there waiting to electrocute me. I bought it for ten bucks
The motor turned the wrong way but I figured that if it wouldn't reverse I would just rig it up different. My luck was running true to form and it would not reverse so I did this. Since my shop is now immense size was not a factor. I can tighten or loosen the belt by swinging the motor. The long shaft under the motor is held in place with plumbers tape bolted to the deck which allows it all to pivot.
The board, bolts and hardware all came from the tread mill so I did not have to buy a thing to get up and running
I cut a bucket for a cover and used two little brackets from the tread mill to hold it down. All I have to do is squeeze the bucket in a little bit and it will come right off
Probably the best ten bucks I have ever spent. I also saved the variable pulley so when I build a polisher I can set it up with an infinite speed adjuster by changing the distance between the drive and driven pulleys.
I have cut a 3" by 6" hunk of jasper three times and it cut smooth as ever.
