I have an older Performax 22-44 that I had to fabricate a motor mount bracket. When I put everything back together, now I can’t adjust the table up. Notice both of the aluminum brackets on both side of the table bracket have set screws (see pic). Both of the these brackets freely slide up and down the threaded rod.. The thing is, if I turn the threaded rod to raise the table, the lower bracket seems to have some “slop” in how it fits on the large tube and it binds a bit. Also, since it is only supported on one side by the threaded rod, I’m worried that it’s going to bend or break on that side. For the record, nothing is siezed up and is lubricated and everything does move (just not up),so I’m not sure what I’m doing wrong here. Any ideas on how to fix this?
