Question on Hafco Sliding Table Panel Saw

[david.elliott]

I recently bought one of these barely used second hand...a 12" one.
It came to me semi disassembled and the Q I have is with the locking thread for the ali rail that is on the sliding portion of the table from underneath. The one you move to make change to cutting angle.
When the rail is at 90 degrees the welded frame does not let the washer between the plastic knob and the steel frame sit flat so the rail moves, unless I use undue force to lock it.
Has anyone one of these set up and can share a pic, so I can compare? The book is not helpful at all...

Can you post a pic showing the problem?
