Spent an hour or so filling up a length of pipe 
With water and dribbling play sand into about a meter and a half
Of 40mm copper pipe, having sealed one end with strong duct
Tape. Kept going till no more
Water and bubbles rose to the top.

Sealed that end with more duct tape.

Borrowed Peter’s pipe bender today and marked up the
Pipe using the old pipe( too low) and some alloy wire
to give a guide to the bottom profile of this pipe 
which has to negotiate past an angle iron “hoop” which is
a feature of GE Cups.

The bender’s shaped fixtures are set up for
Larger diameter pipes so packed the outside of the pipe 
with cut up car magazines.

So far so good!

I’d made the pipe deliberately long in case the bender
Needed some extra leverage.

But this meant I couldn’t easily offer it up to check if
It was fitting OK.

So bit the bullet and cut the pipe roughly to length.
The sand inside the pipe was packed as hard as concrete!

But 5 minutes with the garden hose and it was all flushed out.

It looks as if I’m heading in the right direction but
Some of the curves need to be a tad sharper so
Will have to refill with sand again!! 

Off to vote to keep us in Europe so work suspended
till tomorrow or the weekend.
