I gave up hoping the weather would improve , too soft to do the exhaust @ freezing temps .
So spent the morning watching grandsons footy match , designed a brake pipe straightener for the 3d printer , and finding out why my old pipe flaring kit was a bit naff .
A but of fiddling and filing a bit off and its now doing a good job, only taken me 25 years to sort out
hopfully a bit warmer tomorrow
