Accurate Strong Gantry

[vargai]

The general arrangement is really good. Back to back AC's and floating end bearing to allow for thermal growth. Are you making this or buying?

My friend is renting a small shop and generally I got him to machine the part,and I will put them together.
There are a Bridgeport VMC, a Colchester CNC turn and a Hungarian CNC turn. I used to work here but recently after the daily office job I prefer to have a little brake. That is way I would like to have some machines at home where I can work any time that fits to me.
The bearing is 15 mm bore -for an entry level spindle is Ok but any design comes in handy, thanks.

PS: I have adjusted my setting so the vid is already visible at my previous post to you
