So me and a friend of mine got a idea for a nice back purge plug set up.Were both welders and he also runs a CnC machine,we were both sick of the old methods for back purging tape,tinfoil etc.We wanted to come up with something simple,nice,and reusable.Once we made a set and tried them out with good results some other local welders we knew wanted sets also.So we started making them on a small basis.There made of 6061 Aluminum this set fits 1.25 and 1.50 Sch10 and sch40.It also fits various tubing sizes.Sometimes after being used they were getting stuck and were a real pain to get out,so we made up this wrench that pretty much works like a bottle opener to unwedge it.We also recently came up with a little tray to hold them so there not rolling around and getting lost.What do you guys think?
