I'm setting up my new-to-me FB 640 and am quite frustrated, honestly. So many poor fit and poor casting issues, as I'll explain in the other thread on this machine. For now...anyone can help out with the guides? I'm not as familiar with euro guides.
Lower guides
The lower guides didn't fit well in the frame, which explains why the previous owner didn't set them up well. The fit is too tight so the adjusting lock nuts on the side rollers jam on the frame. Any ideas? As they came on the machine, I can lower them only if I grind away at the silver aluminum body of the guides.
So I've flipped some of the brackets around, and it seems to work, but is still a bit odd. Is this normal?

Upper guides
is it to be expected to readjust the guides each time raising/lowering the guide post? At the top for full height cut, the guides are further to the front of the machine. So I have to adjust the assembly backwards. Also, it wants to twist, so I have to grab the whole guide post and hold it in the correct rotation while tightening the lock. Normal?

general shot, I've got the guides about 1mm off the blade. I use a tensionmeter for the blade so blade wander isn't too often.

Both guides, I cleaned up, the previous owner had probably used some lube with gummed, stuck the wheels, and wore into them. I smoothed them out a bit and they spin ok, not as slick or stictionless as a bearing, but smooth.
