What bearing do we need, you have any pictures of how the acme rod assembly all attaches to the frame?

Its pretty intuitive….I bought everything for mine from Mcmaster carr inc the nested pipe sections. I went with a threaded rod vs a screw jack which I regret.

Will that work with the screw version of the threaded rod? Really could use a picture of it dissembled! I'm sure you need to weld something in this assembly.

It’s for 5/8” threaded rod. The movable end of the press has a plate in the end of the tube with a 5/8” nut welded to it.

Why do you wish you went with the screw jack? I assume it would be faster opening closing? Where did you get the wheel?

 

[BBob]

The cheapest wheel I found at the time was from Grizzly Industrial. It was a blank, it had to be drilled and tapped. I did mine in the lathe.

I'm not sure how this bearing works. Is there a locking nut on the shaft on the other side of the plate?

The nut on the left is welded to a plate at the end of the sliding arm of the press. The bearing has a flange which is held to the plate by the two cap-screws (as seen in the picture posted above) so it is fixed but removable from the plate.

Thanks you that makes allot more sense now. You mentioned You wish you had gone with a screw jack instead of a threaded rod. From your drawing it would look easier to use nuts, Not sure how you would do that with a screw jack unless they makes nuts for those as well.

I used a threaded rod with standard threads. Its slow and stiff.

I wish I would have used this HERE

Precision Acme Lead Screws and Nuts​

In fact, its on my list to tear mine down and change it but I really haven’t even been shooting my compound so it’s not high on my priority list.

I didn't state the jack thing, someone else did. Threaded rod, the flanged bearing, nuts all are readily available, pretty simple and cheap..

What Diameter tube are you using on both ends? And are you using extruded square tube?
