AT-300 lathe-mill-drill - improving the top of the bed (scraping)

Me again.. :) Long time since I posted, but I haven't been idle, the progress on the modifications for this machine has been documented on some FB pages etc., but it was time to post here on YT also, starting with the scraping of the top of the bed. I will also post some other changes I have made, which includes lengthening the tailstock barrel, filling in the bed cavity with epoxy granite, moving the milling head and more.
Anyway, here we go:
Not really needed, but as I was curious how hard the bed was as the machine is advertised with a hardened bed and also found it to be a little "off", I scraped it. The guidance surfaces, i.e. "dovetails", were not very hard. The top, on the other hand, was harder, but not by much, so it was possible to scrape it. The use of the term "hardened" on such cheap machines can certainly cover a lot.. (probably no Brinell test has been done here no..). In any case, this was actually an advantage as restoration of the geometry/surface quality on these surfaces were then easily managed. I started with the BIAX, then used a regular hand scraper for most of this job. It didn't take that long before the bed was fine ie. within the same specs that the Myford benches are tested against and also similar to the "Schlezinger" test (which as far as I can see is quite similar to the now adopted DIN industry standards for accuracy on standard quality machine tools), i.e. within 1-2/100 mm "overall" (for the length of the bed). Actually 1/100 mm "fatter" in the middle. Initially it was not more than 3/100 mm or so sway (down in the middle), probably not from wear, rather just as it comes from grinding which is within the specs as documented to which it is made.
