FOG members mention that Festool knobs can be used to secure Veritas Parf Dogs and other devices to an MFT top. These use an M8 metric thread. I need a few knobs, but don't have Festool hold down devices with knobs. I cobbled several together and then came up with another homemade solution.
I bought M8-30mm threaded bolts, a pack of 5/16 x 1-1/2" diameter fender washers, and found a handle bolt kit with two knobs in the lawnmower department at Home Depot. Punching out the standard nut in the kit, I used J-B Weld epoxy on the M8 bolt head and slipped it right into the lawnmower handle knobs. Two knobs for about $5.50. I can mount the long Parf dogs or small dogs, to the 3/4" MDF table by slipping a fender washer over the knob and slide it up through the dog hold into the Parfs.
While working on the first solution, I spotted a couple of of orange juice, heavy plastic screw-on tops that I use for risers when painting shelves. Bingo. I cut a small square out of plywood, (a round hole saw cut out would also do), to fit the inside circle. Then, I drilled a hole to fit the M8-30mm bolt and counter sunk it so that the hex head would wedge into the square. Some J-B Weld and I had much cheaper, extremely sturdy, OJ Parf knobs. ;D
