Solderless lugs…

I thought you’d be interested in this photograph. It is the lower lug on the bottom of the front downtube of what I believe to be the remnants of an Ixion frame (see magneto support lug). I’m using this and other lugs from other totally cut-up frames to repair a machine with an early 269cc Mk.I Villiers engine.

To recover the lug, I started by cutting the tube with the desired lug from the frame remnant, then started to bore out the rest of the tube from the lug I needed to save. While merrily boring, using the lathe, with this lug secured in my four-jaw chuck, the remnants of the tube suddenly started spinning. First, I wondered what was going on, but on withdrawing the boring bar, there was the remainder of the tube with no evidence of braze to either the tube or its mating lug, so it was relying only on the pressed in brazing pins to hold it to the frame.
