automaxx & seneca woodworking mod MFT table REVISED! parts list & instructions

egsp,
I too have to add my praise for this mod. As one who often wanders down the aisle of my adult toy stores (no I meant hardware stores) looking for items that could be repurposed in the workshop I have to bow to a master. Anyone who has developed a dog of one sort or another for the MFT should be looking closely at this. It makes all kinds of sense.
Thanks for sharing.

Great idea, thanks for sharing
Very nice solution, indeed. Now, if you want closer to be Festool green you could consider using a Prevost high flow coupler, at least that one has a green button for the quick release. If you use air tools the Prevost couplers are very nice and worth a look.
OK here goes:
Parts list;
1. 1 -- M8X1.25 x 40 stainless socket cap screw/ bolt
2. about 3 x 5/16” stainless washers (optional)
3. 1 x fourney pressure wash coupler (male and female)- I would suggest a few extra male probes to experiment
4. Seneca woodworking clamp dog
5. solder or epoxy- I used Loctite Marine grade
female coupler: from Amazon/MidAtlantic Merchant
Forney 75129 Pressure Washer Accessories, Quick Coupler Female Socket, 3/8-Inch Female NPT, 4,200 PSI,( the female ones I ordered from Amazon/ Industrial Supplies and Parts were not identical to the ones sold by MidAtlantic and did not fit as well)
Male coupler: Forney 75136 Pressure Washer Accessories, Quick Coupler Plug, 3/8-Inch Male NPT, 4,200 PSI Sold by Industrial Supplies and Parts
tools:
hacksaw
vise
file and/or dremel
2 or 3 choice curse words (if it doesn’t fit)
6mm hex wrench-

Goal: Cut the male probe so you get a section that is 0.50"
1. cut the tip off the probe –I cut a piece 00.3" off the end--keep the tip!
2. cut the probe off as close as you can to the hex fitting/base- so that you get the longest probe possible
3. insert your probe fitting onto the M8x1.25 hex bolt, reversing the fitting so that the end that was the tip of the probe is now going to be the closest to the dog
4. epoxy (or solder) the probe fitting to the cap end of the screw
5. screw it onto the bench dog,, but back it off a few turns and then try to attach the female coupler (not on the table yet)
.
6. If that goes well, pat yourself on the back, pull the coupling apart and then try attaching it to the MFT. Ideally, you want the snuggest fit possible, and this involves pushing the female coupler up into the table, while pushing down on the dog. After it engages, twist tighten the last few turns (twist the female coupler) until snug. Congratulate yourself on your superb mechanical skills.

look-no spacers!

6. If you don’t get it right, you can just cut yourself another probe (easier) or fine tune if needed. You will be adjusting 2 parameters- “A” the depth to which the probe is inserted into the female, and “B” the distance from the dog to the female coupler-- which is how snug the coupler is going to attach to the table,. You may have to cut a few thin rings off the probe to get “A” right (or even add one back on--hence the curse words). A file or dremel will get you the last 1/100” clearance. You may even end up reversing the probe section. "B" should take care of itself by tightening the coupler.
A- The male probe should seat as far in as possible, just allowing enough clearance for the male and female connectors to snap together. This is key to the coupler working properly—otherwise you get too much play after the fitting is attached. This is another reason to use this particular fitting . Having a long narrow fitting helps prevent wobbling.
I tried various garden hose fittings, none of which worked as well. The simple brass fittings will work-sort of—but there is more play and the coupling mechanisms are not very robust.
Happy coupling!

Seriously cool idea! Thanks for sharing

OK, I modded my mod and made the changes to the instructions, which results in greatly increased stability as well as makes it easier to make and use.
The "twist mod" involves attaching the probe fitting to the cap end of the bolt with epoxy or solder. You then leave a few turns slack when screwing the bolt onto the dog. After attaching the coupler onto the probe on the table, then tighten the last few turns using the female coupler. The friction in the coupler is enough to grab the bolt.
