I think the festool hose fits the ridgid vac perfectly if I'm not mistaken. Sorry I don't have my ridged vac at home to verify.
And no I wasn't joking Woodie. I needed a rail for many applications in what I do. Screwing it to walls to cut cedar shakes to install standing seam, cuting odd angles you can't rip freehand on a table saw. Believe it or not cutting siding freehand is not easy to make straight lines, and when you're installing a $50,000 standing seam roof, it better look straight. I used to always use my joiner anyway, like most people still do. How much do table saws cost? So maybe You wouldn't buy it, but I still would need it. Now there's other track saws around, before, what else were you gonna buy? Honestly, I considered the amazing edge it leaves as a bonus. I was always going from table saw to joiner. If I initially bought it as a hobbiest, it wouldn't be as attractive of course, but I am a professional and you need the right tool for the job. $600, cheap.
