Decided by the end of today I wanted to have both my wing extensions welded in place ready for the next stage (which is building the front section under the lights)
Had a little bit of a practice doing butt and lap joints firstly and based on the results and the descriptions in the book I felt I was ready for the big one!
I'd worked out how far the metal would go before I blew holes in it and recognised the "bacon frying in a pan" sound - I'd also got used to looking through the welding mask and could understand how the weld pool was going.
So armed with my new skill (cough I use the term lightly cough) I set about my wings as follows -
Started with the drivers side and began by cleaning off any paint and then after marking up the location on the wing I secured the extension in place with my new "C" clamps -

A bit p1ssed off initially as I'd bought 2 bottles of argon/co2 gas for use on the wings (I'd been practising with the co2 supplied bottle) but after I'd set up the welder and gas and was about to start I noticed no gas was coming out of the nozzle. Did a thorough check and it turns out BOTH bottles I'd bought are empty! Now hoe the HELL am I supposed tpo prove that I didnt use them!!!
Luckily I had enough gas in my co2 bottle to use that instead - but what a p1sser!
I started by tacking up the extension to the wing -

Managed not to blow any holes but had to go easy as the metal at the edge was a little thinner after I'd sanded off the paint (I used a 120 grit flap disc on a grinder!)
Once this was cool I knocked the extension in place with a hammer to get it as close as I could and then went for it!
Heres the result after the 2nd run (the 1st had already been ground back)

Where the 2nd run joins is actually in a dip created by the curve of the wing so it'll all be hidden by a skim of filler. Also it had penetrated in most places (which according to the book it doesnt need to do with a lap weld?!?)
I ground off the excess to get is reasonably smooth - at least flush with the edge of the extension anyway. There was a slight raised edge of weld at the "back" however it's not higher than the top of the wing so wont be visible when skimmed -
