Hi Rick,
I'm always a little skeptical of You Tube videos where they show you how but this time they were 100% correct. Dad used to say when something went wrong that the "Operation was a success, too bad the patient died." The bend on the tubing looks exactly as if it had been bent in a high end tubing bender,
Mother on the other hand after I said it wouldn't work would ask how I knew since I hadn't tried it. When it didn't work it was because I hadn't tried the correct method. Try it again. In the end I always seemed to get it done properly.
As much as I'd like to short cut a lot of things, everyone has been with me on this ride and some for years and they deserve the very best. It's up to me to provide it.
I was thrilled to see the sprockets when I was looking for a way out of the corner I was in. As the old fella that owned the service station where I worked when I was a kid would have said "A cornered rat will take any available way out." This was usually when he'd found a way out of a problem.
Steve.
