Experimenting
The gas-pipe frame I found last year is not exactly a paragon of craftsmanship. For example, all of the (stamped) lugs were tacked onto the tubes with huge blobs of steel (and were fairly crudely welded together in the first place) which, even for a junker frame that I’m going to throw random parts onto as an experiment, are a little bit beyond the pale even for me.
So I spent half an hour this afternoon cleaning a couple of the more hideous welds so they only look awful:
I don’t know if I’ll end up with a ridable frame, but in the worst case it will end up being a less-hideous practice frame.
