Working on a sewing cabinet project and thought I'd show off my TPG. The project required two sheets of ply cut into 12 pieces. I was going to make my rip cuts first and thought I'd see how accurate of a cut I could get with only using a RHS t-track and TSO square.
Don't know if I was lucky but I was shocked to find I was only off by 1/32" ove 8'. I measured from the back side of the rail to the edge of the board - so probably not the best way to check but I'm still impressed:
Even though this looked to be acceptable accuracy I added my LHS TPG for my cuts:
I've been working with another track saw systems for many years but this was not only quicker but more accurate than my previous method of breaking down sheet goods. I still had to measure every piece vertical/horizontal/diagonal but my confidence is growing.
Some comments on the system:
1) When I put the various length t-tracks on I held them toward the rail when tightening. Seems like the stop plunger is in the correct position for all tracks w/o need for calibration but I need to verify this with test cuts.
(Edited: test cut with all 6 t-tracks and found the 20” & 30” LHS/RHS are almost spot on to each other but both 50” cut 1/16” oversized. Have to think how to correct for this as I don’t want to calibrate for every setup.)
2) On size of the tracks. A 50" was added from requests but my project had a couple cuts just over that. I just marked them and cut. So maybe no need for the 50" track? This is my second project with the TPG but finding the 30" may be all you need for most of the work.
3) Wish the LHS t-track didn't depend on a square that attaches to the underside of the rail. On setup it's one more thing that takes time to make sure the tracks are centered - i.e. the sheet needs to be trapped between the squares. Maybe a rail connector similar to WP and Seneca PEG's?
4) Holding settings. I saw complaints about the WP system with so many connectors losing setting with common bumping of the stops. I actually found the same on the TPG! This occurred at both the flipstop to t-track and flipstop plunger. I found you really need to tighten everything very tight.
