David - Thank you for your input. The suggestion of building a sled that covers the slider as well as part of the cast iron table (with layers of the foil tape on the bottom side) seems like the perfect solution. The only part that is not yet clear to me is how you deal with the ring inserts that?usually provide support right by the cutterhead. Depending on which size head I use, I would have to mount the entire sled further away from the fence which?may make the support of the workpiece problematic? Also, I suppose you do not clamp above the cast iron with this sled when using the slider since it would flex too much and bind with the cast iron? Would you still recommend I get the Felder tenoning plate for its stiffness and rigid build when I make narrow tenons??

Lastly, when you say my sliding table could use some alignment attention, you mean because?I get binding or because?0.2mm is too much of a height?difference in your opinion? The machine originally shipped with 0.6mm (right) and 0.3mm (left), but I have since corrected this to be 0.2mm on both sides. As you say, the last 10+% on either side are a different story.

Imran - yes, PF for jointer is something else I have been reading up on in the FOG archives. Haven't?come to a conclusion yet. Someone pointed to the fact that a feeder might press a bow out of a board that will be there again once out of the constraints of the feeder? I work a lot with very thick and bulky hardwoods (tropical 50-65 mm thick and 160-200mm wide) so I can't shave several mm off in a single pass. Feeding by hand, I usually go max 1mm in each pass. Another problem is that my AD741 does not come with a place to mount a feeder, so I would need to have a very solid independent place to bolt the feeder where it won't flex away from the jointer, yet can swing away when I need to open the unit to use the thicknesser. Really don't understand why Felder has mounting options for the bigger units, but not for the AD741?

Many thanks to you both for your very helpful feedback!
