I spotted this useful item on Ebay (need tube with curved ends to replicate part of a coolant crosspipe for my Jag V12) www.ebay.co.uk/itm/330645254032?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649In the description the seller gives the centre line radius as 76mm Anyone know how I would establish the centre line radius of the ends of mine?  might be possible to repair/replicate corroded end of coolant pipe with Ebay item above how to work out centre line radius? draw a circle inside curve and measure from middle of circle to middle of pipe? |

draw round the outside and inside, then measure and mark out the centre of the two (it will vary a bit as that bend looks a little crushed)
you've just drawn the centre line radius, to check what it is; either find something that matches it, such as a roll of masking tape, dinner plate, can of beans etc.
when you've found something close measure the diameter of the item, in reality you'll only have a choice of CLR's so pick the closest you can

Hi again Good Scrap. I took your advice and just happened to have a saucer almost exactly same radius. I emailed the vendor my details which is 57mm CLR and asked if he could put 2 ends on a piece of pipe. He relied to say that the tightest he can do is 63mm, which is probably ok, but the price has jumped to £22.50 plus £7.50 p&p  I was expecting 2 x £4 plus a little for the straight section (the original listing is £4 a bend). If I can't find any other options that will need to do I suppose. |
