You need to go vertical my friend.? This will solve all your problems and give you room to spare.

Building vertical gives great benifits in space saving with little to no disadvantages. In fact there are really no disadvantages other than you can't use the bed has junk table.!

But there are many advantages over conventional horizontal setup.

Huge space saving.
Better chip clearing due to falling away with gravity resulting in better finish.
Noticeable Longer tool life due to less chip recutting because of better clearing.
Cleaner area around machine again due to gravity and chips falling to floor rather than being slung around workshop.
Cleaner table due to chips and mess falling meaning less cleanup between jobs.
Easier access for material loading, fastening and work area.
Easy to build cabinet around it keeping all mess inside (Think Large wardrobe)

I upturned my old machine years ago to see how it would perform vertical and it worked so good it never came down until day it was ready for a Refurb.
I was Given an unfinished project which suited me to Finish and use my self so the Old machine could be refurbed.(Which I've since sold)
The new machine was horizontal and I used it like this for a few months but soon got tired of clearing the mess off table and hot chips smacking me in the face all the time or coolant being slung or running all over the place, not to mention the bloody room it took up.
So couple of months ago I tipped it up made a few hacks to frame along with small counter balance for heavy gantry and it's now on the wall in vertical position working like a charm.

I wouldn't have a horizontal machine again even if I had the space, which I do, so this should give you some idea to how good I rate Vertical machine.
