Thanks Guys
The end caps are pot holed
and as that is the bit everyone can see its is best to start with facing those. Mounted in the three jaw and held by outside jaws the first cut was made. You can see that the casting was slightly thicker on one side than the other on the first cut. It took two more cuts to get rid of the pot hole but it still has plenty of meat left
I repeated with the other end.
Before turning the other sides I need a gauge that is going to be the tube, which of course has not been cut square
Holding this in a three jaw is not a good idea as it will distort the tube and as soon as you show it the tool the flexing of the tube against the tool pressure will let it move
So best knock up some bungs, in this case I have found a couple of bits of plastic from the come-in-handies shelves and turned them to be a tight fit into the bore. One on either end and these can be used to hold the tube while it is squared up.
Did I mention the piece of tube is not the 60 mm long as ordered
I have been in contact with the very nice Lady at Polly Wobbles and she is sending me two pairs of small roller clutches for £13.90 a pair, they only charge £2.50 P&P and I have been promised they will be here tomorrow
