I've recently purchased the cordless Makita track saw and I'm really liking it (thanks to a discussion on this forum)!
However, I'm struggling some with a quick efficient way to square the rail to the panel. I can get it square using my squares and such.
I looked up what was available and it looks like there are a couple of track rail squares that cost around $160-$180 (TRS GRS-16 & Insta-RailSquare).
I'm curious what others use to quickly square the track.
