First off, based on what I have read here, I got myself a Workforce saw today. Yes, it is a great tool at a great price! Thanks to those who recommended it. My workshop-- under construction Now, for my questions. I have an old squirrel cage fan that I think is a good candidate for a polisher. I say that because it is only a 1075 rpm motor. Based on what I have read, this might not be fast enough to make a good grinder/lap machine. Am I correct on this? If so, then I have a small problem I could use a suggestion or two on. I have had this fan for 25 years, and it was old when I got it. Still runs good. But, the fan is rust welded to the shaft! lol Been soaking it with PB Blaster all day, and banging on it, etc. Might there be a pulley removal tool that would help? Hope to get started on a flat lap soon. As well as building some extra bench space! Thanks; Mike

Mike, you might try a steering wheel puller.
Yeah Kev, I use my WF outside...

So far, the water pretty much goes all over me. :lol Yea, you make a good point, I will either make some type of backsplash or just move it to the yard on a table to do my sawing. The portability of the saw is a big plus!

Nice start. The motor isn't too slow, and even better for a flat lap. You can always use an arbor and belt/pulley system to vary speed too. If it gets warm in the "shop" you may want to reconsider tearing the fan apart and look for a motor elsewhere A gear/pulley puller www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=8832 is what you may need. Be careful beating on the end of the shaft as it will mushroom and you'll have to grind it back down before you can get the pulley off. Use a piece of 2'4 wood on the shaft and don't forget to prop up the fan so the motor is hanging free when you strike it. Best to get a puller...got any mechanic friends? A 6 pack can go a long way in these cases . And get yourself a quartz-halogen light for inspecting your stones, as it shows the color better. Dr Joe .

Quart-halogen, eh? Never would have thought of that, thanks! Yea, those 3 jaw pullers look like the way to go. I have a two jaw, but it just won't fit on there well enough. It may be too large also. I'll go by the auto parts store this evening, see what I can find. Yea, I hear ya on the fan issue!! Thanks Dr Joe

If you can get between the blower and motor clean the shaft on that side. Using a socket or similar over the shaft tap blower towards motor. Clean the shaft surface with sand paper strip. Carefully pry blower away from motor. I'm assuming you removed blower set screw. Also you can try using crescent wrench to hold shaft and try turning the blower. WD 40 or Liquid Wrench would be helpful.
