For what it¡¯s worth, I had that little fence on my K915 and I don¡¯t have it on my Kappa 400 and I don¡¯t miss it a bit. I¡¯ve never said ¡°I wish I had that fence¡±. With Macs clamps and Brian¡¯s parallel fence I¡¯ve never even thought about putting the wood in front of the fence. So for those ordering a new saw I would suggest to save the money. Maybe for those who have it already, just set it aside and see what happens. My two cents?

The only accurate reference surfaces on the X-Roll sliding table are the two chamfered surfaces on the top of the P-channel. ? Otherwise, the sliding table is an aluminum extrusion made by squirting molten aluminum through a die in a manner similar to how Macroni is made, with features that vary as much as ¡À1mm. ?Have a look at the following post from earlier that discusses this aspect. ?

The outrigger table aligns via this angled and machined surface with two saddles that mesh with the angled profile, and is the mechanism by which the outrigger table (and fence that attaches to it) go off and on the machine yet consistently register square to the travel of the sliding table.
Machines with a longer sliding table are typically delivered as a ¡°kit¡± with the sliding table and overhead saw guards removed for transport, and thus require precise calibration and alignment during installation. ?You can see what¡¯s involved in aligning the sliding table by watching?, and for a $1,500 fee, Felder will send a technician to your shop to commission the machine and do the necessary calibrations and alignments, although not to the same level of accuracy as the method I document. ?If you do plan to install and commission the machine yourself, you will need some specialized tools to do the job -??is my curated list of ideal tools for this purpose. ???will show you the quickest and most accurate method of squaring a crosscut fence on the sliding table (the fence on the outrigger, or the shorter alternatives). ?Lots of ?other Felder-related resources on my??and?.

Indeed there is a design flaw with the Felder short (1100mm) crosscut fence for the X-Roll sliding tables. ?Full analysis is covered in a series of videos at the following link:

David,
?
those links are very informative, thanks.? As someone who doesn't currently own a Felder slider, but is just thinking of buying one, looking at what you had to do fills me with a certain amount of anxiety.? The implication is that Felder isn't overly concerned about how accurately the saw parts are machined, and that each saw purchased may have an unpredictable set of problems.? More generously, perhaps they just don't view the t-slot on the slider as needing to be accurate, and the rest of the machining gets more attention.? But I'd imagine that most people would hope for the t-slot to be something they could use for attaching accurate jigs.
?
I wonder if anyone has established with Felder which parts of the slider are intended to be accurately machined and can be referenced off of, and which are not?
