looking for ideas to build 5 axis mill turn machine

[JAZZCNC]

Personally, my plan is an epoxy granite base, linear rails, gang/live tools, and a spindle cartridge.
I'm still trying to decide between a flat or a slant bed. Slant is far better for chip management, but it means I'll need to find/make a couple big precision wedges for machining the base.

Think that would be my approach as well but using a mixture of precision granite surface plates for the surfaces fastened to aluminum structure for positioning/angles etc then cast around these with epoxy granite to give the vibration mass and finished structure.? Think it will be easier this way than trying to cast precision surfaces at the correct angles etc. What ya think.?

Jazz, it's a small horizontal mill column, which would normally have a gearbox in the 'window'.

Thanks, I've since found a pic.

My plan would be to cast the base, then do the finish machining off the rails once cured.
The other option would be to machine everything prior to casting, then have an internal metal structure to hold everything in alignment, but I'm guessing over a 3-4 foot bed length, there is always going to be some level of movement as things cure.

Suppose it's all down to what machines you have to help with the machining.?

A mill with a 40"x10" table, with ~27"x~15" travel, provided I actually get it working.
I just need two more servos and drives, and I think I've got all the major bits needed to get it functional, but I've got a few other projects I want to get finished first.

Ye I'm in a similar position I've got the Semco with 1100mm x 450mm travel, the beds about 1250 x 400 I think. Also Fadal VMC with 500 x 400 travel with bed around 650 x 400.
Fadal is closest to working just sat waiting for motors and controller but the Semco only needs rebuilding and electronics. But with the current state of things and not being able to work then both will be on the back boiler for a good while.!
