Welding is easier than you may think. And you can hire the kit and gas quite cheaply too.
thats not my issue, I can weld, mill and lathe, OK...ish, but getting all the kit you need is a bit of a trick, renting it is not cheap, there are things call "make spaces" which might be an option, but I've got nowhere to keep such a beast any road.

I'm not sure that getting someone else to make one is the same as making one yourself, you could just go and buy one form India for 1500-2000k (apparently), and would Norbs just give you the CAD's he's a generous chap, but that's a bit much, maybe?!
I have a design in mind, but I'm not sure it would work, and if you were building one yourself you would need to work out any issues as you went along - if you've not done much fabrication before it might become a bit intimidating!!!!
do you have any ideas in your head johners?
