,

John auctioned one set of them a few months ago and I was the winner of that auction.

I also have a couple of sets of Festool clamping elements, a half dozen Workmate dogs and about a half dozen yellow dogs from a Craftsman table.

I use all of these things in different situations, but these dogs get used more than all the others combined. I bought some of the extruded aluminum rails from 8020 that he mentions in the auction. They attach perfectly to the dogs and bring a lot of options to the table. I picked up 4 4' rails for $54 shipped, not too bad.

I have a couple of MFT/3's and I haven't touched the angle unit since I picked up these dogs and the rails. I also haven't bothered with the brackets that attach the guide to the table.

I measued the holes in my table with a caliper and John machined them so they slip in perfectly, no wiggle and they don't have to be forced at all.

I do have one pic of them in action in my thread on the Oak Wenge spiral staircase. Kind of distant, but you'll get the idea.

If anybodies interested, i can take a few pictures of some setups I've used.

Among others I have tried, these work particularly well (and are much less expensive than some).

Peter, do you have a part number?

Anyone see or use the Qwas rail dogs yet? They are longer then the qwas dogs and bolt into the bottom channel of the guide rail and you them simply drop them down in the holes in the MTF table.

To you guys who bought bench dogs from John on Ebay, is there something better than the stock Festool fence that still allows use of the guide rail.  All of the extrusions I saw from 8020 that seemed to accommodate the bench dogs were too tall to use with the guide rail.  I just got a set of John's bench dogs, but I realized too late that the holes in them were at a height to match the fence on the MFT/3, whose T-track is twice as high off the table as the MFT1080's fence.  I'll probably just send two dogs back to him to lengthen the holes, but before doing that I thought I'd see if someone had a better solution.

The McMaster shoulder bolts (20 mm diameter shoulder) work very well and are far less expensive than the alternatives.  The 20 mm shoulder bolts are available in a range of lengths -- the least costly is 50 mm (2 inches) with a 30 mm round head.  In another posting someone mentioned using the round head of a 20 mm plug (like the one on the shoulder bolt) to align the guide rail and fence rail with 1-2-3 blocks.  The person mentioned using sound to align the complete system of guide rail, fence rail and bench holes.  I first place a pair of rectangular blocks flat on the table with the 3" side (not 2" side) of the 1-2-3's against the fence rail and use an accurate 90-degree square to align the fence rail with respect to the bolt heads located in the table hole pattern.  If the fence rail is not quite in alignment with the holes, you will hear a "rattle" of the 1-2-3's as you test their mating against the fence rail.  The fence can be brought into good alignment with the holes by loosening the fence rail retaining knobs beneath the table and then nudging the rail tight against the 1-2-3's until neither block rattles against the fence.  Repeat this procedure with the fence and smooth side of the guide rail extrusion.  I find it best to always place the reference "sounding" blocks against the fence rail.  It proves very convenient to have the holes and rails in square alignment.

Check out the track option at http://www.woodpeck.com/supertrack.html - While I don't own it, their super track looks to be a robust option with a lot of flexibility.

I have John's dogs and use them with 8020 rails as well as with a 3' piece of T-track and it works well.  I'm finding the T-track is really quite adequate and a lot cheaper (and lighter weight) than the 8020 rails.  No reason you could not use them with a much longer piece of T-track.  I use two pieces of it at a right-angle for a corner clamping brace with great success.

As an FYI, the toilet bolts that John shipped with the dogs have to be ground down slightly to accomodate the T-track since those are 3/8" bolts and most T-track is designed for 1/4" bolts. 

I saw a lot of discussions in one of the threads about cutting square panels.  With John's dogs and using the holes in the MFT, I have no issues at all with square panels.
