excuse me whizbang but i don't think anyone said anything negative about ryans adventure in scraping but actually commented about the spindle runout. it has been pointed out though that what you get for your money isn't that terrible considering you bought the very lowest priced version of these machines. from reading here there seem to be much more expensive models that aren't so popular that you could have purchased instead where there is likely more attention paid to tolerances and uniformity. these bargain mills are cranked out asap to supply demand so inconsistencies from one machine to the next are to be expected. your situation seems to bear this out. ryans may be off .003 but yours could be .001 or .005 at the same measuring point. you can try to scrape it but following someone that is learning as they go might just turn out to be a story of what not to do, no offense.
