Any work your doing with a hack saw will certainly be better cut with a portable bandaw for a very low price.
With my main limitation being floor space as well, I found a way to make use of currently allocated floor space by converting my HF portable band saw to mount to my little used shop press
This was such a simple conversion that i thought someone might find it useful.
Basically remove the handle, move them to an new work box, then use current mounting holes (and a little scrap) to mount to the press:
I was clamping it in the vise for a while, but I feel tools, especially the band saw, needs to be ready to go.
Speaking of utilizing space, I have a 18" brake mounted on top of the press, and Im going to mount my 1x30 to the other side next.
Then the whole thing is on locking swivel casters and easily moved if need be.
No replacement for a vertical but adequate for my needs as soon as i finish the table top with miter slot.
