Leeway:
Thanks Guys. Good stuff.
I did get to quasi finish the initial design. These images may help to clear up what I am shooting for.

This will have provisions for a top to be locked down on it. It will also have wheels on one side with handles to move around a bit easier. Think hand truck.

You can see the arbor that I intend to use. I will initially set the top plate that spins in the skate bearings at about 3/8" offset. The way this motor and arbor mounting channel mounts to the frame, it will be easy to add extra offset. That part will be adjustable by swinging one end of the channel.

The best part about this machine and it's design is that I have just about all the parts on hand already. Left overs from other projects. It does a heart good to get rid of some stock that has been taking up space. :thumbup:

I only drew one row of bearings, but will use them doubled up in case of vertical movement of the barrel when jumping around. Also the pulley ratio is off as drawn. There will be a larger pulley on the arbor. Likely 3 to 1 to pull the RPMs down below 600. This too may need tweaking. I only drew 1/2" shafting and pillow blocks because that is what I have on hand. I may need to bump those up to at least 3/4". 1/2" has a tendency to flex a bit.

Any thoughts now guys?
Thanks.

Leeway:
I already made a different drive design. Instead of the way I had originally planned, I will just use a flange bearing under the barrel. Not cam or skate bearings. Instead, I will do like most other machines and use offset weights.
I have some 1 3/8" square steel stock that should provide a good offset. The plan is to make them 3" long to start with.

I am also switching the shafting to 3/4" now. This will mean buying more bearings, but better safe than have to swap out later.
The pulleys can also be swapped out later for different effects. The weights can be rotated on the shaft closer to each other for another effect. The support springs will be able to be tightened or loosened to also vary the shake.

I don't see much of an issue finding the right shake with this type setup.

I will also use one of those water heater pans made of galvanized. This is what I will actually mount to the machine. It will then hold the tub in place with possibly a strap clamp. This way I don't need to install any drains in the barrel and when it wears out, put a new one on.
I can get the barrels at no cost.

I intend to use 4 or 6" PVC pipe in the center of the drum with a threaded rod to attach the lid or cover.

Anyway, here are the new images.

That's looking good Lee, wish I could draw like that !!

:clap:
