Re: Saw stand wheels, on floor or off the floor?

 

Lots of good information in this thread.

On motors and wiring, I continue to be surprised that nobody seems to be advising the use of motor overload protection ("motor starters") with these saws.? Given the ease with which a saw of this sort can jam, and the temptation to go off and do something else while the saw is working, overload protection seems (to me) an obvious need.? Either the NEMA type, using selected "heaters" or the IEC bimetallic type will work.? NEMA motor starters have gotten very expensive new but are easily scrounged, at least around here (US).? Typically heaters are selected from tables based on the motor current or horsepower, but you don't have to use the full capacity of the motor.? There is no reason not to use a lower rated heater or setting to cause an "early" trip to protect the blade or whatever.

Safety note:? Many motors have internal automatic resetting thermal protection (fan motors, etc).? It's unsafe to use this sort of motor, as is, on tools as it may restart without any warning if you forget to turn the control switch off after an overload trip.? No reason not to use the motor, but the thermal protector should be bypassed or replaced with a manual reset type (the sort with the red button).? Or of course, IMO, use an external motor starter.

Sorry I'm late to this discussion.
The Files section of this site has a doc I wrote on changing motors (Replacing 4x6 bandsaw motors v3.pdf).? At the back of the doc is a section addressing stability issues from putting on heavier motors with photos of the setup.? Basically using steel strap bolted to the sheet metal legs.? The wheels are spaced wider and are further back, with the weight taken by the wheels. Though not sold as resistant to flat-spotting like Guy Lautard's one, they've never developed any flats.
Although its cheap, the saw is heavier to move (due to wheels further back) and awkward (by comparison with cart mounted ones like Dave Sieter's). I wouldn't do it that way again.
I've got a 2-drawer filing cabinet, that I'm going to castor-mount on an angle iron frame.? That will give me a flat surface to mount a tray under the whole saw to catch coolant and swarf. Will be a bit wider and higher than std, but much more stable and have storage for blades and fixtures underneath and be easy to move - jv
