andym Posted June 26, 2012 Share Posted June 26, 2012 Can anyone recommend a firm that can make up pieces of metal pipework? The Abbot has a coiled steel expansion pipe between the water pipe and radiator that should look like item 29 on this drawing: Unfortunately mine looks like this because someone obviously forgot to undo it before removing the radiator! I could do with someone to salvage the ends and make me up a new piece of pipe. Any suggestions gratefully received! Andy Quote Link to comment Share on other sites More sharing options...

Andy Andy, Why not make it out of copper pipe, anneal it then form around a suitable sized round object. Quote Link to comment Share on other sites More sharing options...
Tony B Posted June 26, 2012 Share Posted June 26, 2012 Cupro nickel pipe is very mallable. What size is the pipe? Quote Link to comment Share on other sites More sharing options...
scruffyHerrbert Posted June 26, 2012 Share Posted June 26, 2012 Pipecraft on the Lancing Ind.Est. have some useful machinery in their workshop not cheap for what I wanted but perhaps a continuous coil could be less labour intensive? ended up having a play with a friends vice-mounted pipe bender and using some stainless 12mm x 1mm tube from Pipecraft, successfully made up the compressor to sensing tank pipe (amongst others) I was missing during brake conversion - I started with copper but was concerned about metal fatigue given the compressor is engine mounted and the sensing tank chassis-mounted (although with a rubber hose also fitted in line helping to absorb some vibration, perhaps I didn't need to worry) - was pleasantly suprised to find the stainless tube worked easier than the copper - the extra hardness helping to hold it's shape around tight (for example 140degree) bends - the restrictions were getting really tight bends in opposite directions immediately following each other due to the way the tool grips the pipe but I copied a steel original (it snakes around to aid cooling of the compressed air) borrowed from a fellow Dodger and was happy with the end result - not sure if the continuous coil in that diagram could be achieved with the tool I used but good luck with your search Quote Link to comment Share on other sites More sharing options...
andym Posted June 27, 2012 Author Share Posted June 27, 2012 Thanks all -. I need to measure the pipe but it's about 4mm od from memory. I wonder if something other than steel is the answer, perhaps I could bend it myself round something of suitable diameter and then get someone to do the ends?

Tony B Posted June 27, 2012 Share Posted June 27, 2012 Silly question, but does it have to be coiled? Quote Link to comment Share on other sites More sharing options...
Austin Posted June 27, 2012 Share Posted June 27, 2012 The coil will help cool as already mentioned and also to act as a shock absorber, as on BSA Bantam D1 fuel lines! :-) Quote Link to comment Share on other sites More sharing options...
Tony B Posted June 27, 2012 Share Posted June 27, 2012 My Dodges, both Ex Norwegian have cupro nickel brake pipes. The pipe from the master is coilded, I suppose for same reason. The pipe is very easy to shape around a former. Though squashing can be a problem. http://www.frost.co.uk/automotive-brakes-tools/brake-pipe-and-tube-bender.html could be a worth while investment.
