When I first read the post i assumed that the 44 was a miss print & you meant 440mm not 44. Hence my reply was not relevant. Apologies

Sam look atthe likes of the Proxxon table saw, sort of thing ship modelers and dolls house makers use with small blades. This is why I also mentioned about pully size on the main spindle.

Izack for that small as saw I would forget about a rise and fall worked by a handwheel , simply have the table on a couple of slotted legs and adjust the height that way. Same with the table make that tilt as its far easier than the trunions needed to tilt the motor/ spindle assembly like on on full size saw. Sam may be aware of the old Kity Combi machine that work like this but that had a 200mm blade.

But apart from the reduced friction side would it be possible to run a toothed belt inside out. That is with the smooth side contacting the pulley?

.

Before that specific question gets lost ... Yes, the small toothed belts [MXL for example] seem to work fine inside out, as a flat belt. I use them on my little 'Jason' lathe [running on pulleys designed for flat belts].

The smaller the pulley diameter the greater the slip with a smooth flat belt, which is of course why toothed belts are used by Proxxon.
