The guzzi's then new stainless front exhaust pipes were not bent quite enough on the lower bend, the rear end drooped and looked awful.
I filled them with dry sand and plugged them. I made a wooden jig to test for the correct angle. Plenty of heat and it was surprisingly easy with two of us.
I have used the bending springs Bernard mentions, when installing the central heating in my 3 story house of the time. They are buggers, get it even slightly wrong and they jam in and you can easily end up scrapping the piece you're working on. Even bending copper is heavy work, I can't see anyone using them successfully on steel. Better off getting the plumbers pipe bender.
The racks mentioned earlier were bent using a small bending m/c. Similar to the plumbers type but quite a bit sturdier. I think 1/2" or 5/8" was its max size. I was able to make the side frames which the Krausers hang on very easily.
The tricky bit was sourcing material without buying a lorry load. Fortunately the 1/2" stuff was kicking about at work, but quite a bit was from my scrap bin. Cummins pushrods, ERF cab tilt pump handles, made of T45 that! A few bits of child's pushchair got in there too.
Plus some 3/8" kunifer brake pipe for the little rack to bungee the tent to. I used a brake pipe bender for that. Works really well, not as fragile as I thought it would be.
All knocked up in tea breaks.
The real tip is ... never throw anything away!
