I have seen 3/4” ply, 3/4” MDF and even 3/4” particle board with melamine on both sides. I know festool opted for the MDF, obviously not because it is lighter than 3/4” ply, but perhaps because it is less expensive too. The particle board with melamine gets a really, really slick top and would be excellent in glue up (clean ups) but seems it would have a tendency to chip out as well as the plywood. Thoughts or observations? Remember will be drilling plenty of 20 mm PARF holes and have a semblance to the Paulk support underneath it.

If you can find it, I’d opt for garnica. It’s a high end ply from Spain.

Extremely flat and smooth.

They use MDF for a reason—it’s dead flat and stable. Even the best ply isn’t. The issue with melamine—as you said—is friction. You want to be able to keep pieces in place. You’re also on the money regarding glue, but you can avoid that using some waxed paper under the joints.

I do have to ask why you’re adding dog holes to an outfeed table. Do you intend to use it for glue-ups as well?

I guess I’m missing the MFT reference. The Festool MFT is part of a system. At its most basic, you can use the Parf dog setup and tracks to do some very accurate cuts (assuming your dog hole spacing is dead-on).

Are you planning to buy Peter’s guide system? Without it, you’re just drilling holes.

I made an assembly/outfeed table using an old desktop (it’s one of my early project posts). You can often find them free or for less than the sheet goods. I am not sure exactly what type of plastic it has on the surface but the underlying material is particle board. It does make a great assembly table because you don’t have to worry about gluing your work piece to the top and drips just pop off with a putty knife.

When you talk about chip out are you talking about while cutting to size?

I am not fond of the melaine stuff. I use MDF, doubled up to 1 1/2 inches thick, edge banded and then Formica on the sides first then the top. Holds up, oh forever unless you cut it with the saw, OOPS.
