I modified one of my extra lot-o tumblers last year just to see how the new cement style motors would work. I have a few lot-o's so I was able to take before and after videos that documented the noise level and action of the rocks for an original and the newly modified. It has now been about a year and zero issues with that one and my end results never suffered. Two days ago I bought a fairly new double barrel model that came with two extra barrels for $40 because it had a bad motor. I remembered seeing a post on Facebook awhile ago where somebody mentioned making a solid adapter plate so I took this opportunity to design and fabricate a plate for mounting the new motor so that the original lot-o frame is untouched. This allows either style of motor to be put on in the future. It should be robust enough to not dissipate any of the vibration frequency. I Painted the new plate and motor black as well. I think it looks like it belongs now.
No fancy tools needed. I cut the 3/8" aluminum plate with a hand jigsaw and drilled and tapped all the holes with a cordless drill. I threw it together quickly with bolts I had on hand but I will be replacing those and adding thread locker and lock washers after a trip to the hardware store.
I did switch things up and decided to tap the motor mount holes so instead of thru holes those ended up being 1/4-20 tapped holes.
This is the original way that many people have used to convert them. This involves cutting pieces off the frame and involves drilling 4 holes in the frame.
This is the video comparison I made of the original motor to the new style motors
