Hi flatline you can get 25mm steel tube a metre long from b+q about 7 quid ,might have some at our workshops I'll look tommorrow Thursday could be stainless not sure,I'll ring you if It's the right size.cheerz buddy ady f.
It's only.4 of a mm out, so will it really show?
That's only .2 either side. A bit of light grinding will profile that in with no visible difference.
I take it that the section won't be structural, otherwise you need to consider wall thickness.
I think it will look better with that section in, tbh.
Oh and as regards the spraybooth. I was going to make something similar last year with some shuttering, a bit bigger, so you could do fairing panels.
I intended to provide heat via a paint stripper gun coupled with a thermostat mounted in a baffled section at the base, so that the hot jet of air would be dispersed evenly, but temp controlled....
Should work ok, but make sure you don't have the hot air aimed at unprotected wood, a metal plate or heat resistant foil should keep it form burning or catching fire.
It's not falling off, it's an upgrade opportunity.
