about the casting in the surface plate that's a no-go, 1st I don't own a surface plate, 2nd even I did I wouldn't risk casting epoxy on that thing! and I want to see my friend giant (to me) machines tackling my parts, I'll have the chance of playing in the Pro League XD
about the spindle, yes I should be ok with the servo 3.7kw 12kRPM, 17.6NM from 0-6000rpm, at 12Krpm I should get 3.5Nm from the curve they sent me, and that will be plenty for my needs...
I abandoned the metal way covers for the time being, got in touch with a chinese company that makes way covers and those guys make the Accordion Bellows type covers for all axis to my spec for 350usd... that's 5 covers including one armored one (nylon fabric accordion with steel angle sheet protecting the fabric) for the Z axis... shipping included... they look pretty good and all people that buys it are very happy with those... I won't even bother the the metal ones lol... at least for now...
so I'm gathering the funds to buy all the linear stuff should make the order by the end of the month, meanwhile I'm searching for some good epoxy... I got in touch with a couple of dealers let's see what solutions will they have to me... also need to study some aggregates, need to source many grades of rock and sand... next week I should have some news on this camp... need to find granite sand...
