Remember we had a pretty direct discussion about the frame connections through bolts and the open design in your thread.
Did it worked out for you, would like to know if you had any problems with chatter etc.
Have to say the endresult sure looks nice, wish i was at that stage with my machine.
It is just like all the VMC concepts, just like arie`s Beagle and Justin and yours VMC.
Only difference is that this machine is a lot smaller, table is only 230 x 135 mm. The outer dimensions off the machine are 500 x 500 x 500 mm,
( so 20 x 20 x 20 Inch ). The L-frame is only 200 mm wide ( 8 Inch )
Spindle diameter is 30 mm with a max. endmill off 6 mm.
Complete machine is made off Epoxy Granite, also the connection between y and x axes.
Allready have 3 Kuroda GP1002 c3 preloaded spindles, 12 THK HSR12P wagons and 6 rails and the NSK NR3060S main spindle with Maxon 250watt motor, all new through ebay.
Think this will be the final design, only have to do some face milling and tapping some holes for the rails etc. I dont have any machine over here so i have to pay all the machining and that costs a LOT!
Had bought a China spindle but i`m not happy with it, same for machined parts from China for another design i made. (price for the parts was great, paid and then they told me the extra cost for shipping, Man that was a lot, happy they refunded me the initial money)
Kind regards,

I'm good. The Mini VMC is pumping out parts like a champ. There are a few things I'd like to revise when I have time. Mainly the spindle.
I don't really have any chatter issues. I still want to make up some polyurethane mounts to sit it on. I still have a long ways to go before I can call it a VMC.
I'm back and fourth on ATC designs, I still need to make an enclosure, which I changed my mind on about 5 times so far.
My big thing right now is making a new spindle. Keep your eye out for a new thread appearing soon on my spindle build.
