Ed, I have them indexed with 4 dowels, and then I have them bolted to T-track I have mounted below the spoil board (there are little 3/8" slots cut into my spoilboard above the T-track). This set-up of t-track with slots cut into the spoilboard (the slots don't go all the way to the edges of the spoilboard) allow me to still use my vacuum for sheet goods.

Thanks Russell

"I have them bolted to T-track I have mounted below the spoil board (there are little 3/8" slots cut into my spoilboard above the T-track)"

If I follow correctly, the t-track is embedded in the "black" plenum under the sacrificial spoilboard?

I have been struggling on how to easily mount high pressure low cfm vacuum fixtures without interfering with the high cfm vacuum for sheet goods.

For those times when I want to use a vacuum fixture and not my spoilboard.

I have this 1/3 sheet of 3/4 mdf I just screw down to the spoilboard and hook whatever I want to that.

You could add T tracks to to something like that to set on your spoilboard when cutting small things. Or use screws and tabs or make a vacuum fixture out of mdf and paint it.

Yes, I have the T-track embedded into the black plenum. I cut my own plenum though, that left open spots for the t-track so that I could glue the spoilboard around the track and reduce the air leakage. Then I glue a whole spoilboard down, and cut little 3/8" slots down the centre of the T-track with a 3/8" compression bit, with a little wider spot in the centre of each track so I can get a T-bolt down into the track. Works great. I can still hold down full sheets with vacuum, and surface the spoilboard like normal, but I can also bolt down my jigs with the T-track.
