I was having a hard time to get consistent width and parallel rip cuts from boards that were narrower than 6”, so I would have 5.5” boards to be ripped in 1.5” strips and I could not make the cuts consistently with my festool tracksaw. So I browsed the web, and not wanting to invest $300 in the Festool parallel system, and I found something that even I could make. Here is the original
I made some modifications (added a ruler) and in stead of the bent metal to keep the track in place that the original had, I put some 1” x 1/4” hex bolts and a wingnut to clamp it to the base. I also added a stop at the right side of the base so that the wood would have something to stop it from sliding when moving the saw. Since the track is bolted to the base, it may not rest solidly on the wood, so there was a chance of movement.
It works perfectly, for the cost of about $15. The beauty of this system is that the track does not move and that the strip you’re cutting is underneath the track, so you basically just push the new length of wood to be cut under the track until it butts and rip away.
I also made some spacers from hard maple to accurately get the most common widths. Just put them in between the movable part and the back of the track and there you have it.
Fool proof, even for me. Although I should say, checking if your vac that’s hooked up the saw is maybe full to the extent of exploding helps with accuracy. Sawdust was accumulating under the track because the vac couldn’t hold anymore, this led to 1/32 to 1/16” deviations in width. Once it was sucking properly there was no problem with getting exact cuts.
Next thing I want to do is to make this more height adjustable so that it is not limited to 3/4” stock. The other thought that occurred to me was that you could also use threaded rods with 16 tpi to make this thing super accurate and easy to adjust. Still wrapping my head around how you might do that but I have some ideas to incorporate both the vertical and the horizontal adjustability.
