Thankyou peeps

it's all been rust proofed Chris

it's all been drilled now Panky

and Trev, you're not wrong there mate[^]
Been out there again today and got some more done. Firstly, i took advantage of Tim's little idea here and made a couple of slits in the Cill, gave it a tug and welded some fillets in....This makes getting the wheel on and off easier
I then set out to make the floor section. Some fettling and swearing, a few cuts and abrasions later, it welded in

i'm so pleased to have a new floor in Pia, i thought i would never achieve such things after gawping at a gaping hole for so long

i ran out of gas so the welding was pretty spitty but it tidied up with a flap disk
And this was just gratuitous but i just couldn't resist it...It's not glued in yet but it looks sooooo good, i'm having a few jars tonight as i'm really chuffed that it feels like things are moving forward
Thanks for all the encouragement folks, it really helps when all you feel is jaded by the whole thing HAHAHAHA!
Saw this Dic@head the other day, Pis@ed out of his face!!!
