I have just acquired a SM2502 (slightly elderly s/h and not expensive) but feels tight enough. I will only know when I start to use it, of course. There is a locking handle (three of the same and with the same number for all three axes of the machine) The one which clamps the table is loose on the screw and I need to use a screwdriver to lock or unlock.
There is a list of spare parts on the Sealey website and I have identified the part (SM2502 030) but it costs £9++ so I was hoping to mend it. However, there seems to be something complicated about the handle because it can only operate over a limited range of angles and there is some sort of 'dog'(?) arrangement so it looks like I can't just tack weld the handle to the screw.
The handle doesn't seem to want to come apart. I imagine it's a part for many different units so it shouldn/t be all that (£10's worth of) special but there's this apparent restricted movement problem.
I'd bet someone here has had and sorted this same problem.
