Interesting practice material. Where did you find octagonal bar stock?
Thanks. I saw some hexagon, but not octogon. I have found that square does well to practice narrow runs where you did not intend to have the work follow over to another side. I was hoping to find some octagon stock that would be appropriate to work on designs intended to move over onto another side of an octagon barrel. I don't know why hexagons would not work just as well for that purpose. I have been using metalsonline.com. Glad to have another good source.Allen...........Speedy metals have all the metals you will ever need, except gold and sliver, I just ordered 6" dia. round for lap dics. 1/2" long. I have seen octo, square etc on the site.
