My own personal take on the matter, is that I'm not really in a position to do things any differently..
i.e the goal of having a no overheads workshop, (without real heavy duty stuff like a PT or whatever)
and one which could be moved and made functional somewhere else without too much bother, with no guarantee of space, needs be made compact, and also somewhat adaptable to whatever floor it may be on, what's turned out to be of importance,
as the floor is soft and crumbling in spots, which is on the list of workshop things.
I've done much the same thing as yourself with the angle iron, and threaded some studs into the top.
Didn't plan on getting a 24" bandsaw, it was just the cheapest route for a capable machine,
would've ended up with a tablesaw anyway, so hey ho.
All my stuff being aimed for some kinda productivity, (bar the second TS, which was kinda, only worth the hundred quid)
though I can certainly see why many might get the impression of anything otherwise.
The belt sander is needing a "makeover", so perhaps it might be a case of 6 of one...
Pretty much all I've been doing is working on saving space in some form or another,
and being in a damp moldy workshop, sheet goods not an option.
Plenty of metalworking to do in order to make things functional, but thankfully getting a bit closer
and not planning on getting another machine, well apart from a dust extraction system,
(which motor I was wishing to pilfer from said tablesaw)
Pretty much everything I'll be doing for the next while will involve wheels.
Sorry for possibly derailing the thread, as I guess someone considering a combo vs separate machine outlay,
likely doesn't have quite the same criteria as what I see fit as a necessity.
All the best
Tom
