Just used to use tank tape /gaffer tape and draw 2 opr 3 lines with a marker over joins so you can see alignment . then you can just tack one bit on to another [ if youved got a good fit up with no gaps et ] Then clean off with solvent before welding - let the solvent evaporate thouroughly...
Just thought it would be cost effective as well . I would be a bit worried about constant vibration on welded alu pipes especially with the xtra weight of the throttle bodys hanging off them. Best of luck anyway.
Really nice stuff excellent , but one thing , would it not be better to have the pipe going into the exhaust flange almost to the cylinder head face and [ 2-3 mm ] away then tig welding it before flushing it off ? Then the exhaust gas wouldnt hit a big step in its flow . Just a suggestion , but...
Get hold of a standard inlet and cut it down as a starter , much easier than trying to draw it from scratch. If the bodys are going to be held on with sillicon tube all you need is a small stubb of alu tube welded on . It will be cheaper and less likely to break as well .
Dont know if it helps but i used to use 1mm strips off 1.2mm sheet cut on guillotine for welding titanium exhausts Cheap and was made from the the material as the tube i was welding .:laughing:
Yes , but its where they would get the original dimensions from isnt it . As for cost you cant really say that would cost a fortune as they might have a cheaper method of doing it that you are unaware of .
Also , metal shrinks on cooling , well i never , who ever would have thought of that...
That looks like a really good job you've done . Just a suggestion , but maybe it would be a good idea to take it to a foundry now its back to the correct shape etc and get a quote to make another or batch for others as well in case the repairs dont last .
Those are fantastic sculptures . Chunko , you might do as well to appreciate that a lot of work has probably gone into that sculpture even if its not to your tastes .
Hi , your best and most straightforward way might be to contact your local welding place and speak to there repairs guy .Hewould be best to have a look and might tell you if its worth converting/spending money on bits and pieces . He may even have 2nd hand cheap bits or be able to knock a kit...
Hi , To find out angles of bends just buy a digital protracter/angle measurer . You can get a good one of a ebay for about £35 - the big chunky looking old fashioned ones .
I used to make exhausts for F1 and we just used to draw around sections of tube on sheets of paper and measure the...
