    Advice: Re-scraping a diamond bedded surface plate

    That's actually my next project. I started building one a few weeks ago. Right now I have it partly roughed in on a optical "rail" as a proof of concept. Bunch of glass and a moncromatic source projecting. I have all the glass, lenses, screens, beam splitters on hand. Still need to order some...

    Advice: Re-scraping a diamond bedded surface plate

    That all make sense and is good insight. Truthfully I do believe I'm sharpening these blades adequately.

    A Scraping Newbie Has The First Of Many Questions

    Thank you, I'm in the same boat - my tins just came in and my curiosity now has me looking like I murdered a company of Smurfs. I bought the tins for their cool-factor, but now I see the fool-factor. I'm hoping that the Stuarts will show up with a bit better contrast. I've been stuck with...

    Mahr Millimess - Indicator disassembly, inspect, clean, reassemble

    Thank you for this post. The first few photos and details gave me the guidance and confidence to open mine up and adjust the main spring so that the gauge will read without lifting my surface gauge off the plate. Dont know if all the vintage examples had that much force, but a gentle flex of the...
