Over the last month or so my 18 year old 20 gallon shop vac has been starting to have some whine in it's shutdown. Figured the bearings were going out, but the other it just wouldn't start up. After some disassemble and checking the switch and power cord, both checked out. However upon one last power on check it started up again, but noticed an electrical burning smell. So either the brushes have gone or the bearings are letting the armature rub on the windings.
Having seen good reviews both here and on google for the Rigid vacs, I decided to go with one of them. Well, actually I came home with two, the 16 gallon and the 14 gallon vacs. I need one for work around the house and cleanup in the shop. The 14 gallon will be mostly dedicated to the cnc as the duct I ran from the central system is a bit too far of a run and doesn't have enough cfm to support it.
After assembly, I'm not real impressed with the design of either unit. At least the 14 gallon one has a tool tray, though the 16 gallon one has a bag for tool storage, it's not optimal, and hose storage is difficult as the top slopes off. I think we'll see a upcoming cnc project to remedy the tool tray situation, as well as an added hook for hose storage.
Here are both units
I was hoping to find a new motor for the old shop-vac. Anyone know if the "univeral" motor is consistent across other shop vacs? Or know of where I might be able to find the motor itself. I've checked all the tool part places and all show it as unavailable, surely the guts of the motor can be bought and retrofitted into the old housing.
