Table Base materials and T-track

[jTr]

Though I've found plenty of discussion on table materials and t-track, wondering which layer to fasten it to. Simply put, here's my plan:

1> Plywood Base bolted to frame
2> Glue down Medex MDF
3> 8020 brand 1.5x.75 t-track fastened to layers 1 and 2, framing MDF plenum vac-zones.

From previous threads/photos, looks like some have bolted T-track to 1st layer of ply... am I going overboard, or is 3 layers better?

Mine has 3 layers of 18mm MDF with the track being set into the top layer.

That is how I did mine, but T & G a piece of Maple around the border of the Maple ply. It works well keeps most of the chips on the table and is a place to bolt a fence to

Alan,

"That is how I did mine, but T & G a piece of Maple around the border of the Maple ply. It works well keeps most of the chips on the table and is a place to bolt a fence to "

Did you mean more or less a gap filler in that 6 3/4" between base sheet and the aluminum rails? I like the idea of chip containment and was wondering about attaching squaring blocks/fence as well - sounds like that covers both subjects...

3 layers 3/4 mdf, bottom/base layer bolted to frame with t-track fastened to the bottom/base layer. Seond layer cut as squares and screwed and glued to bottom layer. Third layer same as second except no screws, just glue. Top layer is the 'spoilboard' layer. After many clean up dressings I just cut new top squares and re-glue. Special note I put just a little bit of silicone seal on the bottom of my t-track in addition to the screws to hold it in place. Russ

I also have two tracks down the sides to hold full sheets etc,.

I just used slatwall.

Yes Jeff, it does fill the gap to the side rails. In Russ's pictures he has them on the sides. I did mine on all four. I think the maple adds some strength to the maple plywood.

I'm the guy who takes a month to get his new machine running - Some would say I research excessively, but your input is invaluable in my efforts to avoid reworking the setup!

Thanks to all!
