You can tell a lot about a person by the company they keep, and you can tell a lot about a craftsman by the tools and jigs he or she builds. Whether for one-off jobs or long-term use, these ad hoc tools, like this tubing rotator for a welding shop, help deliver results beyond the ordinary.
What we appreciate about [Delrin]’s tool is not how complex it is — with just a motor from an old satellite dish and a couple of scooter wheels, it’s anything but complicated. What we like is that to fabricate some steering links, each of which required three passes of TIG welding to attach a threaded bung to the end of a rod, [Delrin] took the time to build just the tool for the job. The tools slowly rotates the rod, letting the welder keep the torch in one position as the workpiece moves under it. The grounding method is also simple but clever — just a wide strap of braid draped over the rod. The result is some of the prettiest and most consistent welds we’ve seen in a while, and with an order for 28 steering links, it ought to be a huge time saver.
It may be time for a little more TIG welding love around here. Sure, we’ve covered the basics of oxy-acetylene welding, and even talked about brazing aluminum. Perhaps your humble Hackaday writer will take the plunge into a new TIG welder and report from a newbie’s perspective. You know, for science.
