big abrasive saw, initial report
I've been posting a barrage of questions related to a 16" abrasive saw which I
believe is the same saw as an Everett 16" dry cutoff saw made today. I bought this saw yesterday from a guy who bought a warehouse and contents at a bankruptcy sale. (Today I found out the guy who went bankrupt was once a friend of mine, sad story.) It wasn't running, and was priced accordingly - pretty cheap. I hauled it home today, put it on the bench and started monkeying with it. The first thing I did was rewire the motor from 440 to 220, put a plug on it and fire it up. My phase converter starts it fine, don't know if it will run it full blast or not until I get a little farther. (The motor is 7.5hp 3 phase and I'm running it off a phase converter with a 7.5hp idler.) The motor is incredibly noisy. The bearings are probably shot, most likely 6205 and 6206. I may replace them but it would be a lot of work. As far as I can tell the spindle bearings aren't very noisy, but until I rebuild the motor or replace it with a quieter one, I won't be able to tell. The vise is both cool and unfortunate. It's a nice cam-action vise which works quickly. The bad thing about it is it only works at 90° and 45°, can't cut any angle I want. I may think of a way to cobble but for now I'll go with it. The machine has been hit sometime in the past. The stand (a sheet metal affair) is pretty bent, and the fiberglass belt guard is broken, and the motor's electrical connection box, an aluminum cast box, is broken out around the power wiring, which comes in via flex conduit. The switch is old but works fine. There was a simply incredible amount of grinding swarf caught up under this machine. Big chunks that must have weighed 25 pounds were falling off. What's left seems to be very tightly bound. I may take a crack at trying to fix the fiberglass belt guard, because this machine, already dangerous, would be about five times as dangerous with 3 V-belts running fast (the motor runs at 3450 rpm) driven by a 7.5hp motor, were the belts to be exposed. The main wheel guard is a solid aluminum casting, in fine shape. The main castings of the saw are heavy aluminum, and they are in good shape. The upper casting, the one that swings up and down, had been fitted with a long handle but the handle broke out and is gone. This is the biggest issue with this saw. I'll probably just weld a 3/4" pipe socket at a 25° angle to a little steel plate and bolt it over the broken out hole in the casting, and use a piece of 3/4" pipe for a handle. No showstoppers so far. This saw certainly *looks* like it could cut steel very seriously indeed. GWE |
