    On the manual lathe, the most common turning carbide insert tool I use is a Kennematal NKLCL-0805V (left) & NKLCR-0805V (right) with uncoated NPL 51 K68 inserts (trapezoidal with two cutting edges)....

    Yep, and if you don't line that collar up JUST right, and/or anything has a tiny burr, it will get stuck either on the spindle or the key, and if you force it, it will get really stuck. That collar...

    Had a co-worker, a chemist, many years ago that worked at one of the nuclear facilities (in the middle of nowhere, can't remember which one). He described the machine-shops where they machined...

    Years ago when I did some shipping and account with Fedex, they would routinely change the package weight to MUCH higher than shipped (e.g. small packages in envelopes, weighed and noted on the form,...

    No inert expert here, the highly positive rake inserts reduce cutting forces (good for limited horsepower and rigidity in a wimpy R-8 BP type spindle), the uncoated polished inserts are also very...

    ***ISCAR F45-ST face mill***, 3" max dia. (I use a 2.5", 4-inserts, 4" is way too big), polished uncoated positive rake inserts (e.g. SEHT 43 AFN-P). Have used that for years exclusively on the BP...

    I dont have a humongous drillpress, but I like the old palmgren vises machined or ground on all faces (you can still find the older palmgrens on ebay). I have two 3" and 5". Nice thing about those is...

    In a previous life, I designed a machine for putting different shaped tiny divots into acrylic for light-guides. We had specially-ground and polished carbide indentors in different shapes (cones,...

    This fix works great, the micrometer heads are working fine. The soft touch button is much easier to use (and of course it works). Even if I could purchase a new keypad part, I'd rather have the...

    Laser engravers do a great job of engraving acrylic (don't know how big your parts are). I've made all sorts of light-guides and diffusors with one. You haven't indicated what the properties of the...

    Have two of the 164-162 2" micrometer heads on a toolmakers' scope. One zero switch wouldn't work at all (even when pressing the mangled silicone button with a probe), the other intermittently. I...

    You might check closely (as with a magnifier or microscope) that what you're seeing is indeed related to "line weight" (or penetration depth), it might actually be some type of microscopic burr, or...

    Just a wild guess, but I'd look at the engraver sliding parts, assuming it has a low enough spring-rate where minor variations in the height wouldn't theoretically make a difference, perhaps the...

    Their website wins all sorts of industry awards, it is absolutely unequaled. Sure, they're not a bulk raw-material provider, but it takes overhead to stock a very good selection of materials in all...

    Since I'm lazy and don't like to reinvent the wheel, if I were trying to build a "dot matrix wood-burner tip", I'd seriously look at stock or modified Metcal/Oki soldering tips and power-supplies. ...

    Thank, yea I both sizes of those on albrecht arbors. They're great for drilling tiny holes on the bridgeport, after spotting with a carbide drill. I also tweaked the springs on them such that it...

    Thanks everyone for your time and input, I appreciate it.
    Ok, here's the saga (CAUTION-a bit long-winded):

    The project required this #55 drill to do a step in a dental lab process. The labs all...

    Thanks for the info Conrad. Those Gaertner scopes and equipment are incredibly made, like the pre 80's Leitz and Zeiss stuff. I noticed that scope has micrometers that look like for tilt of the...
