Hi John.

The slider is 9'. I don't have parallel guides yet but this would be a good excuse to buy some from Brian.

The slabs are reasonably flat. And assuming I can fit them through the planer, I'm not super worried about thicknessing. But jointing is another thing altogether. For example, how should I maneuver the pieces across the cutterhead to ensure that I am actually flattening? I have a power feeder on the saw that I could extend to the jointer; if I simply position the wheels over the outfeed bed, should I run the board crown up, or crown down? If the latter I assume I have to shim but am not clear how to do that.?Does the plan change if the board is twisted?

I guess another option would be to build a torsion box that is 15-1/2" x 108" and run the boards on top of that through the planer. The planer feed beds seem kind of short for that, however.

Thanks for your help!
