You need to make it mind numbingly easy to clamp your stock, we literally have to flip a switch to clamp our stock, the kids like how easy it is. But really, clamp it, Period. Holding it by hand is asking to have it catch a part. Also hold the blade down as long as it spins, Period. If you don't do those 2 things you will have it catch a part and do 2 or 3 things. 1 ruin your part, 2 ruin your blade, 3 send the part flying possibly into someone's face.

No, I mark the part and set up my work stop(shown in the pic) which is a 1/2-20 bolt. I take a slightly oversize cut and measure with calipers how long it actually made it. Then I use the fact that my 1/2-20 it 0.050" per revolution to fine tune the final size. This is one of the reasons I need that second clamping piston, to hold things on my work stop side of the saw. After that, cut and done, cut and done.

If there is a way to get 5 thou on a first cut though, especially on lengths exceeding my cheaper 8" calipers, I'd be all ears :0

First "cut", no. First piece, yes. You should get a bigger caliper, will not regret. But I suppose you could edge find it in a mill to measure it then trim it to final and cut the rest of the pieces.
I may have a slight obsession with my collection of calipers.
