I was working on my box yesterday and ran into a couple of things I need help with.

First, I had to do a rip cut to square up my boards. I had trouble staying on the line and need to figure out how to fix that. Also, I had trouble with the rip trying to pull the saw out of my hand even with I narrowed up the angle of attack. I stopped with I start to feel my palm getting warm so I would get a blister - what am I doing wrong?

Second, my left hand is very week from my injury. I had trouble holding my try square and straight edge steady and so my lines were all over the place. Any tips?

TIA,
Tony
