Bending exhaust pipes for my AJS

[olderdan]

A bit of a saga this one, I sent patterns to a leading exhaust pipe manufacturer (Armours) who said they could make them. Three months later after many excuses from them I cancelled.
Bought a budget hydraulic bender and some 304 stainless pipe for less than their quote.

Made a few tools to assist the process and did it myself. A 32 tooth blade in my hacksaw machine cut the pipe square and clean.

I packed the tube with sand (wood bungs) and bent it cold, turned out ok. A flaring jig was made from a steel block and two domed punches followed by a ball pein hammer worked out well.


So in the spirit of HMT if you want something done do it yourself.

Nice work and looks great.

Alan,

That is a nice bend from a pipe bender, I bet that you packed the sand very tight.

Hi Tony, yes packed very tight, tamped in increments with fine beach sand, we only live 100 yards from the beach so plenty to be had.
