According to another poster the saw in this sale has double turnion. It has xroll as can be seen in pics.

I agree, the double trunnion and X-roll are definitely better.

It¡¯s not a strength thing, it¡¯s an adjustment thing. If the trunnion is out of adjustment, it¡¯s a pretty complicated process to get it right. Felder themselves went to the double trunnion because the single trunnion was more of a maintenance issue and not easy adjusted in the field without tricky jigs or hit and miss type efforts.

The older machines have some short comings, first, if they are as old as mine, you don¡¯t have the X-roll slider, which was a pretty significant upgrade in these machines. Next major design change was the double trunnion. That¡¯s not to say a single trunnion machine can¡¯t be used, but if I had my choices, any new purchase for me would have to have the X-roll and double trunnion, those two things are going to make for longevity and accuracy compared to those machines without.

It¡¯s up to the user/purchaser¡¯s level of competence in doing complicated setting up of the machine as to wether they feel comfortable delving into the single trunnion machine design.

Brian,

I know that but I was wondering what Mike thought.
?
I ran 40 pound cutters on the year 2000 F700z I had with single trunnion and it worked. ?Hansjorg Felder told me the single trunnion was strong enough when I toured the Felder factory. ?
?
That said I would not recommend running 40 pound cutters for production but a hobby user running 6 or even 8¡± cutters on a single trunnion will be fine.
?
I think price is the limiting factor for this lot but I would not worry about the trunnions.?

The older machines have a single trunnion affair and it supports the whole spindle and motor system on one end of the assembly. This brings into account an adjustment nightmare dealing with ¡°angle of the dangle¡± as well as toe-in and toe-out in the other direction. Failure to get the angle correct creates all sorts of issues when tilting the saw/shaper aggregate.
?
All that said, my old machine is of this design and once set, it¡¯s pretty stable. If I was looking for a machine though, it would be the double trunnion machine¡ more easily adjusted and has better longevity of settings, and with the polymer materials used in the trunnion the smoothness and easiness of tilting is considerably better.

For a lot of reasons and assistance from some amazing people on FOG, I have backed out of this deal. ?The accessories and tooling are great, but the high price, age and trunnion issues make this offering good from afar, but far from good. ?Unfortunately, the seller will not part out the tooling and/or accessories and prefers to sell as a package deal. ?
Back on the search and contemplating buying new.
Thanks to everyone for their thoughts!
