A LITTLE UPDATE
Had the disk grinder out again after fillet welding in all the corners of the welded side sections. Managed to keep all fingers and thumbs this time
I went with Jim's idea. More gas, more power for more heat, less wire feed. Put the wire size up from 0.8mm to 1mm too.
Worked really well if you could move fast enough. I got close to a professional looking weld, well, now and again. The increased gas flow certainly seemed to help although I'm down to a quarter bottle now.
Stich welding the faces then grinding the weld flat seemed like a good idea.
It was if you remember to fillet weld the internal corners before doing load testing. I load tested the cab over double bed
I now have 2 single beds to put together.
Had another forage in the metal skip at work and managed to retrieve a 10 drawer toolbox with a couple of dodgy draws. Had that away and with 1/2 an hours maintenance and repair I now have another work table and somewhere to keep my tools and clamps outside in the dry. Well it will be when I cut a piece of an old tarp for a cover.
Haven't received them yet, but on the answerless window question, I have purchased the 2 main side windows from ebay. Not Seitz but something
http://www.ebay.co.uk/itm/Shield-S4-Cas ... 1438.l2649very similar and 1/3 cheaper.
I should be able to pick them up on Monday
They came today and they are great
Also managed to finally unroll the 2mm fibreglass sheet that is destined to be the sides. Its been laying in the garden for about 9 months rolled up!!!!
Not my best idea although in my defence, It is 2500mm wide 6000mm long. The work bench(lawn) is not big enough to lay it flat in any direction. Not unless I cut down the apple tree
Any way, I lay the side section on the sheet and cut around it. Then lay the other side on and cut around that. The fibereglass has a high gloss side that has an adhesive film on it for protection. Sitting here writing this I an hoping I have cut a left and right not 2 the same
The roll turned out to be quite resilient and did not want to lay flat. A bit like a very large clock spring

.
The 2 sides are now clamped inbetween the 2 side frames, and I am hoping for a bit of warm weather to help flatten out the sheets
