Not having one of those, but a more traditional style of 6x10.
My ones (an old axi) doesn't have as good a design for the belt,
and uses a slightly delicate cogged belt rather than a v belt on some I've seen like this one...
Delicate as in if you grind some primary bevels on your tool steel,
whilst using it for all sorts, may have a tendency to start a fire.
My belt got a bit damaged from this,
and the thing was not easy atall to dismantle, I had to cut big gaping holes into the plastic to get access,
It's not been bolted to the base since.
Another thing is the table is small on the one you've pictured, maybe the smaller belt is sized for it, but I assume its a hungry beast.
I wouldn't want to be profiling the end of something long and heavy with that.
There's a flimbsy bit of sheet metal on mine, which I've thought of
sorting, so it's probably why I might be keen on the idea.
The other tables seem about right for the disc, as you can only use so much of it, or it will fling the timber.
The only problem is the abrasive doesn't last long for these discs and are prone to burning,
(a bit tight me for that changing adhesive discs malarkey)
The biggest issue with mine is, you have to keep flipping the piece
so you end up with a crowned profile.
Maybe that design may be better on your machine.
I suggest looking into getting a standard one, and making an edge sander out of it instead, as using the edge of the drum would be a lot less jumpy
for concave profiles, you'd have a faster, easier and more accurate
machine all round.
No need to rush making it in the meanwhile, but a nice project if the job
is large and calls for a table of some sorts.
Maybe I'm wrong on my assumption that it wouldn't be as suitable for the job?
