Hi. Was cutting up some melamine sheets with parallel guides (ripdogs) that use incra tracks. In the past I noticed sometimes when I put saw on track sitting on material the incra tracks would lift a little where the stops are up against the sheet...so for some time now I was using a couple of ratchet type spring clamps (see pic) to hold the track down just in front of stops. I noticed if I was not careful it would actually pull the stop away from edge of sheet goods just a little bit.....then yesterday I noticed the bottom track of incra guides......yeeesh....I've seen the thread on this site on which t track fits festool clamps....heck even participated in the thread as lee valley track works.....new method works really well, melamine is slippery and I find the rail can move if you are reaching a long ways (bad technique on my part...) and rail has moved on me..so I was clamping rail, and clamping track....using festool clamp on t track works no more need to clamp rail!!
