I have been making some progress on my new machine, I'll post some photos when I finish the base and bolt on the mast. I have machined lots of holes in my very expensive piece of aluminum cast tool plate and chamfered the edges on my mill. Had a bit of a problem when I snapped a M3 tap, completely buried in 12.7mm plate. Had to dig it out from the underneath  ::)
 I am just wondering what diameter to make the platen and should I machine groves in it.

I am thinking grooves(maybe U shaped and not too deep, so easy to wipe muck out of) and somewhere between 120-140mm diameter.

I know your platen is 75mm on the Facetron RC, does it have grooves? I think I remember it does. Can you let me know the rough groove spacing if it has grooves.  I'd be very interested in the diameter of the platen on other machines aswell. I have a Gemmaster and the platen is 160mm and flat.

CheersMB

Hi MB,
I'm in Zeehan at the moment, will check the dimensions when I get back. This existing Gallery photo shows my Facetron platten, along with a pile of ground quartz detritus in my splashbowl:

Just looking at your machine RC, you could mod the bowl. Lift it a bit with a spacer to close the gap to the platen and maybe even trim the center lip a bit lower aswell.
