I,m pleased you like your chassis kit
, sounds like you haven,t wasted any time getting cracking on it too
With regard the welding of the SB1.s ...yes that sounds fine with the stitch welding, put the parts in a vice to avoid them moving whilst welding tho.
If you can,t get your own welder sorted, I have a spare Mig ( clarke 151te turbo) that you are welcome to borrow until you get your own sorted , just shout if you need it
we,ll soon see some progress pics eh , we like piccies lol.
cheers
Andy
