wishbone tubes

[peter2482]

im gonna be cutting my wishbone tubes next week when the tube turns up, i was wondering the best way to cut them, by that i mean did you guys profile the tubes to fit around the tube it was welding to. if so how did, coz when i cut them on the saw they will have flat ends. does that make sense?

A good start might be to use a tube mitre program such as:

You input all of the tube details and it creates a pattern, which you print off, wrap around your tube and you then have a rough shape to work with.

thanks for the link, do you just use the template to mark the tube and then cut it out using a grinder etc

The tube mitre programs really help.

Even so, you will be grinding, fettling, grinding, fettling........

even with the tube mitre program its just a case of using the grinder and a file combined with a lot of mucking about. if i were to build another roadster i would definatly buy the pre done tubes from 3ge and just weld them up myself. brings the fabrication time down to hours rather than days

I am just profiling mine at the moment using my lathe,made up a rotory cutter mounted in the chuck,same diameter as the bush tube, made a jig to hold the arm tube and mounted to the cross slide, works a treat.Cheers Brendan.
