I finished my first lugged frame recently and did the alignment with no jig. I used "C" clamps and boards, old hubs, etc. It was a bit awkward and I will probably build only a handful of frames in the future, but really need more precision. I am looking at Chop Source (
https://www.chopsource.com/bicycle-frame-jigs.html) who makes a kit that you provide the square tubing for, and clamp on their fixtures. The basic kit is $370. It looks like it would make a very solid jig. I was wondering what the communities impressions are and if anyone has had experience with these.
Thanks in advance,
