Hi Mark,
pipe if the way to go in many areas.
I just went to the local metal land and scoured their offcut bins.
Precut gussets from thick plate were handy finds, and well as matching sized thick wall tubes that nested properly.
Then it was more lets say 'organic' in the design, started from the bottom, worked up, that bit looks ok there etc...
Pipe is more flexible (!) in the design than square tube as it lets you pick up angles easier, ie weld a tab on to tube and its sort of universal, rather than onto a then to a rectangle. Dont forget i'm an officeworker not a boillie, so apologies if thats std knowledge to everyone. You need a decent bit of stock trough the front panel 'gills' if you go that way, its not very wide.
my Mark II would probably have a height adjuster via threaded bar to make it easier to get it on off the rotisserie,but higher than my pay grade for now. Just check Marties one for the you beaut version complete with disks and cup holders.
And Marty, sold to that man there.
It might take me a while though, I don't go at your speed but they have your name on them.
Plus my eldest has just bought her first batchelor pad, and I'm doing the dad thing painting, helping with the reno, new kitchen, carpets, floating floor, downlights etc,etc, etc,etc,etc, etcetc,etc, etcetc,etc, etc
poor escort still hangs suspended in the shed with its guts hanging out waiting to be welded back in.... :(
