So I got the tumbler last week (I think that was it). Brand new tumbler, not just the motor. Wow. I took it downstairs, hooked it up, and started cleaning. works great. I then took the motor out of my older Midway tumbler (the style with a column in the center) and put that in the body of the other Frankford Arsenal. Exactly the same mounting holes, and it took about 15 minutes to do. Now I've got two of the better designed bowls humming away down there. The older Midway tumbler had holes in both the bowls I had for it, around that center column, and leaked dust all the time. These new bowls won't do that.
Very impressed with F.A.s service. will happily buy from them again.
