It still needs some minor work, but it works as is. Total cost without the lap discs is under $10

It has a small motor that was laying around. It is 10" across and 8" high, built with scrap 5/8" plywood. It has the bottom of a plastic bucket for a splash guard. It is a direct drive unit. I need to secure the splashguard yet, so I can use it vertically as well as horizontal. I also need to supply airflow to avaiod overheating of the motor.

It's good to be Canadian.

Looks like it would be easy to put a computer cooling fan on Brent. They almost always have those at princess auto for a couple of bucks.

Nice job Brent.On the one I just made the arbor sticks up thru a pvc plumbing fitting,it is threaded on the bottom and I used an electrical locknut to secure it,then seal it and the drain fitting with silicone.The water flies off the wheel and drips down thru the drain hole and back into the water tank to be recirculated.There is no seal on the arbor shaft but so far after a couple hours of use there is no water at all going down the shaft hole.Mounting a fan on yours should be real easy,a "muffin" fan used in computers would be a cheap way out.

rocknrob: There was a shop in Portland, don't know if it's still there called Kenny and Zukes who made the absolute best pastrami sandwiches I have ever had. The problem is every restaurant thinks their sandwich is worth $20 now and seldom makes the grade. Nov 12, 2024 9:53:31 GMT -5

rocknrob: So, to end my thread on sandwiches. If you find your sandwich worthy of that price by all means keep going to that restaurant (chewie)
