Mark, thanks for the detailed response!
I have a couple of questions: In #11 you mention using the 22" end of a 96" piece to reference the entire length against the crosscut fence. I have a hard time thinking I'm going to maintain <1mm error at the infeed end using that approach. Any variation at all against the crosscut fence would yield an error at the other end. Do I understand correctly that is that you are recommending? I think the solution here is the parallel rip guide extension to the table, but that's going to take a while to order and is an expensive option.
Yes, you understand correctly. There might be other methods but this is the way I was taught and have cut at least a 1000 full sheets if not more of material in my lifetime, it should stay put even without clamps. in my business and the three shops i worked I never saw one clamp or parallel guide in a shop and one of those shops had 4 sliders, I didn¡¯t even know parallel guides existed until a few years ago when I bought my first Felder saw.
- There is nothing wrong with using a parallel guide or clamping if that works for you, i have spent a lot of time behind a slider and am very comfortable with it?
And I see in #13 and #14 you also recommend changing references from the rip fence as bump stop to cross cut stop. Assuming both are calibrated that shouldn't be an issue but it seems odd to have to change references while performing repetitive operations. That's an opportunity for error to creep in.
This is standard workflow on a slider as I know and have seen in professional shops. Remember the goal (imho) is to use the left side as much as possible and not reach over the blade which is why the last piece is referenced off the xcut fence stop otherwise would need to change the fence extrusion to the forward position then use the saw like a cabinet saw.?
Yes, your saw has to be calibrated and the xcut stops must agree with the rip fence stop, add in the parallel stop and that will need to agree as well
Imran, thanks for the warning about clamping and using the rip fence. I noticed that the sheet walked away from the rip fence by about a mm as it traveled. The blade seemed ok with it. I'll make sure not to do that in the future. I guess I will try to get the U arm installed with the table in place. However, it may very well be easier to take the table off. Now that I have the leveling nuts set it shouldn't be too hard to put it back in the right position. Or I'll practice using my third arm with the two wrists and extra flexible fingers. I am greatly amused that the Felder manual suggests having "two reliable friends" assist in the process. Thanks for the videos, Bruce. I will see how much I can absorb from them.

11. Pull outrigger back, rotate piece right so the 22¡±+ is against xcut, flip the flipstop over ,the one you set to 22¡± earlier.
12. Push piece against the stop and make a rip.
13. Now take your 22¡± wide strip with the 8¡¯ edge against the xcut and slide over and bump against you rip fence set at 22¡± and make a cut then repeat 2 times
14. The last piece left on the outrigger gets cut by using the flip stop on the xfence.
