Mm,
Thanks for the excellent advice. If I find a CL deal I'll definitely jump on it. Are most of the ones you see 3 phase? I need one large enough to insert an entire 4x4 axle so about 80 inches tall. If I come across a good deal on a smaller one do you see any issues with welding in some panels to make it taller? The only other thing I would need to do is extend the sprayers correct?
Most of the ones I see are 3 phase, its going to be hard to find one the size you are after that's not 3 phase. I don't have the large shop I used to have and I also don't have the 3 phase either. I run several of my machines which are 3 phase from a Rotary Phase Converter. You can find plans all over online on how to build them, its very easy and not that expensive, especially if you keep it basic like mine. Really all you need is a 3 phase motor that is at least the size of whatever is on your machine. My jet wash cabinet has a 7.5 hp motor for the pump.
The one I have is big enough to put that axle in and I see them that size just not as often as the smaller ones. You could I would think easily make the cabinet taller by simply welding a box of sorts to the side of the machine.
The top of the machine usually has the motor and drive for the turn table. If you added a box to the upper side so a axle would fit, lengthen the fluid supply pipe and drill and tap in a couple more jets, it would work. Or just add the box to the cabinet, run it for 20 minutes, flip it over, run it again for another 20 minutes to clean the other end. That way you would not have to mess around with the jets and sprayer.
Finding a big one like mine would be ideal, and I've seen them for around 1k on CL, if you find a smaller one for a deal you could with a little creativity I would think make it happen.
Another thing that a lot of guys don't know about phase converters. You only need the converter to start the machine, not to keep it running. Start up your phase converter, start up your jet washer, turn off the converter. Doesn't use near as much power that way.
I'll keep watching this thread to see what you end up doing.
