Richard,
I came across the thread last evening, but it was matter of
life or death if i took time to reply. I was to take THE BOSS out to dinner. As everybody knows, I am only 39. She is a little less, but as of yesterday, we have been married for 48 short years. The years were short, you see, as we are both a lot younger than we have been hitched. You now know which part of the opening choice I opted for. :

Any how, it is too cold for me to do the work I have to do today, so i have time for discussion for another hour or so before it warms up.
I have not had time to watch your vid, but I cannot tell from the pics if the stubs on the stop dogs are long enough for my application. I am using 1/2" sacrificial strips on my MFT between the table and the materials I am working with. As I look at the pics, I am sure that if they are not, one could still use them by keeping the T-Trac in between the sac. strips and set a stop block to the top of the T-trac. My extension dogs (my head is a bit hazy this AM, so don't recall the terminology. Hey, I'm only 39, the memory will come back eventually.) are just barely long enough to catch the rail clips when cutting 3/4" thickness with the strips under the wood. I am sure there are others who also use sac. strips under their wood who run into the same problem.
Perhaps some bushings can be made to fit such situations. Any how, I would like a set of the new stops. I can see how they could be better in some situations. I am not unhappy with the rip dogs, clips, parallel dogs and all that i have already gotten. It seems i never have enough dogs as long as I don't run into problems feeding them all. Atleast they don't bark when hungry. They just gather a little bit of dust when not in use.
