I've done a quick schematic to show the various parts of the lathe. I've omitted the Cross-slide detail to keep it clear. It is to scale at the size of the Osaki 300.
The Head-stock bore is the hole that goes through the head-stock to enable longer lengths of material to be held - usually for making batches of small parts.
I would recommend supporting the free end of your tube with a chamferred bung which is also supported by a revolving centre. These are not supplied as standard so you need to buy the revolving (or 'LIVE') centre and make a support bung - from alum/steel/delrin/wood - it doesn't really matter what material you use, it just needs to fit on the open end of the tube and have a centre-drilled hole in the tail-stock side.
Naturally, in use, the tail-stock/Live Centre will be pushed up to the Alum tube - I've separated them so you can see what I mean.
You might also consider the Warco WM 150 which has a more powerful 450W motor though a smaller bore (11mm) and is currently £30 cheaper than the Osaki. I do have first hand knowledge of Warco - I have one of their milling machines - and can recommend.
