Found out my old foreman's trick for cutting down tube sheets with a plasma torch actually saves me about 20 minutes per job

I was skeptical when he told me to run a soapstone line and hit it at a 45 degree angle instead of straight on, but after trying it on a 3/4 inch sheet in Detroit last week, I cut my grinding time in half, anyone else got a weird tip from an old timer that actually works?

Respect the hell out of that old timer for sharing that one. 45 degree angle sounds counterintuitive but plasma torch likes cutting at an angle more than straight down, makes sense it leaves less slag. I've been using the same trick on 1/2 inch plate and it saves me from having to spend an extra 15 minutes with a flap wheel every time. Funny how the guys who have been doing this for 30 years just know little things like that. I still remember my foreman showing me to let the torch rest on the work piece instead of floating it, I was fighting porosity for months before that.

Noticing those little tricks old guys pass down is just like discovering a faster route through town that everyone else somehow missed for years.
