I picked this deal up today for $30. Montgomery Wards cast iron grinder setup with a 1/2 hp Century motor. I see many possibilities here. It came with 2 grinding wheels 1" wide. I`ll have to buy good wheels though. These are aluminum oxide. Will they work at all? Attachments:

This motor is about a 10" diameter, 50 lb. power horse. I have no idea how old it is but check out the serial #. Y1. I will be able to run a saw off of this motor quite easy I think. Attachments:

I`m gonna have to expand my work bench I think. Vibe in picture started out as a Chicago Electric vibe. I changed cord, switch and motor plus added a 4 blade cooling fan. The base frame unit and springs are all that was original. It now sports a Dayton motor and fan. I`ll call it a Spencer Electric Vibe how`s that? Attachments:

It is likely "series Y1". Capacitor start will be a big plus for starting a saw. One problem I found with my dad's old home made equipment was none of the motors were thermally protected. Instead of overloading and shutting off all smoked and died eventually. Your motor doesn't say so I would advise not letting it run unattended.

I just gave one of those Wards arbors to a friend. It should have sealed ball bearings, which will make it a good candidate for a 2 wheel setup. The only drawback is having to remove the shaft to replace a belt. I'd find a newer motor to use. As John said, that one isn't thermally protected. If you have a collection of antiques, clean that motor up, and add it to the collection. Don

I wouldn`t walk away from it either since it`s probably as old as I am! lol If I do use that motor it may be just for temporary use of the grinder until I get another one better suited for the job. It may however get some use as a saw motor since a saw is on my list of builds coming up. As I gather parts from different sources I will be building my own. I can do it a helluva lot cheaper than buying them. And being retired I have lots of time. And whiile going after the grinder I stopped at a nearby spot and found all kinds of nice flints and a couple of fossils. It was easy enough to change the belt. It had been garage kept so it had no rust. Do you think I`d be better off using a drip system or building a coolant tray for the bottom of the grinding wheel?

Either way,drip or under wheel spray, you'll want to build hoods and trays. Otherwise you and the area you use the grinder in are going to get a shower of rock snot. You'll want to run a drain line from the trays if you use drip. An easy alternative is to put water in the trays and shove sponges between the tray and wheel. The wet sponge will supply enough water to the wheels, and cut down on the amount of spray coming off of the wheels. Ain't retirement great ? I've been retired for 7 years. Don

Thanks for the input Don. The sponge design is sounding like a good idea to me. A tray is easy enough to build out of fiberglass. And I really don`t need a continuous duty motor for a grinder or saw and wouldn`t walk away from the tools either. Who does that? I`m a simple hobbyist so I really don`t need to build tools Cadillac style. I`m keeping my eyes peeled for parts and motors constantly as well as being equiped with a Grainger catalog. I buy what I cannot find otherwise from there. My rotary and vibe both have Dayton motors from there. Large scale tumblers may be in the near future beween Darstcreek and myself. We have been tossing around ideas on them.

The sponge in the pan has been used for many years by do it yourself type rockhounds. Don't hear it mentioned often. I think that's because the equipment manufacturers want to sell you their overhead and spray watering systems. My first grinder was built from an old yard sale bench grinder. I made my pans and hoods out of scrap ABS plastic from the trash bin at work. My watering system was 2 old glass IV bottles hanging above my bench, but I used sponges to control some of the spray.

Frantom Combo units came with a grout sponge for wetting the sanding drum on end. My dad's motors all burned up while using on grinders and sanding drums. Something always goes wrong (rock slips and jambs under wheel, etc.). Before I could unplug, smoking motors.
