Lug and fillet brazing on the frame tubes. Fillet brazing is far more challenging. All engine mounts and brackets are tig welded as bronze is more susceptible to vibration cracking. You probably should double up your base piece of unistrut as it will have to control the twisting forces of the entire frame. Also, never force a frame into a jig. It needs to be carefully fitted without loading up any of the tubes, otherwise when you pull it out of the jig it can distorte. Building frames is actually easier than building gas tanks. Good luck.
