Oil leads to porosity. I only use acetone on oily stuff, a wire wheel is good enough for most anything else, heavy rust gets a hard wheel. Flame cut stuff gets a wire wheel, and that's on xray pipe. Certain pipe jobs get very weird about grinding marks outside of an area that will be covered...

Yup, the transformer style are very robust, and will last pretty much forever. With a large enough power supply to the shop, and potentially a rotary phase converter, you can use industrial ones as well, which can be found quite cheaply and will have a near 100 percent duty cycle, and much...

:lol: I would definitely shy away from inverters, a blown board will cost as much as a new machine. I'm a union steamfitter and pipeliner, and have burned up several over the years, most of them repeatedly. If you want to spend money, buy all means do so, but that's not where i would spend it.

Yup, I'm sure the horse is dead, but I'll keep beating it anyways: welding is a pretty simple skill that will change your life. If i can do it, so can anyone. Unlike woodworking or other similar hand skills, welding will allow you to build things that actually can make you money, far cheaper and...

:lol: i hardly ever flattop them, but then again i usually don't need to for what they are when I'm using them (hangers e.t.c). I do usually round the corners tho, and back bevel so the weld is on the inside, the outside welds just slick it up.

Properly coped angle iron too! Nicely done!
