Test punch | Page 2 | Power Hammers and Presses | Forum

Steve: I have a pipe level left over from my pipe welding days in Kodiak. It has two feet that sit on the pipe, a rotating level ,and a center punch in it. Find top dead center and center punch it. Rotate level 180 degrees and center punch the other side. Very accurate AND inexpensive tool. You can also use a pipe wrap,center punch a spot and go half the circumference around the pipe and center punch the other side. The pipe level, though,is dead on. Am I being too simple here and not getting your question??

Lay the round on a smooth surface. clamp or hold secure. run a square up to the side of the round. scribe a mark exactly where the verticle leg of the square touches the round.repeat this on the oposite side. you have just marked both sides. rotate 90 degrees.voila..... top bottom. this is an acurate method of layout when you only have a square and is well within the acuracy of a hot punched round stock hammer blank. we dont always have a wraparond handy. another methed. two squares.. lay oposite over round with two legs parrelell.scribe the demension where the other legs touch the round.
