    Big problem with pouring is that I already have holes drilled and tapped. PVC hose on screw, greased and threaded in keeps threads safe but disturbs surface.
    My mistake, taken machine shop word for flatness and drilled before checking.
    Today chiselled off all poxy epoxy and made map of unevenness.
    Two opposite corners are 0.1 and 0.35 mm high.
    Remaining 700mm and 600mm of each rail are within 0.02mm, easy to scrape in.
    Good news is I got my money back for machining.

    Plan for big deviance is to use dremel with carbide burr to speed things up, one cross pass takes 0.05 off. Take it to within 0.05 with burr then continue by hand proper way. 20-30h should be enough.

    Base cleaned up and ready for scraping:
