    Genx optical comparator

    You've probably already been to the GenX website, they've been around for a long time, I'd think they could get you a PDF manual. https://www.genxcomparators.com/page6.html

    OT: home backup power generators

    When I lived way off the beaten path, 15kw Kohler with 1000 gallon buried propane tank. It ran the house, including the heat pump, well pump, and cistern pump, no problem. Saved my bacon more than once, wildfire or ice storm.

    Possible to account for gage runout?

    I'll keep a long story short, lol. I tried the spin indexer system and was happy with the results, more or less. I figured I had about 0.001" runout baked in the cake. Since I had all the parts and pieces anyway, I repeated with a simpler V-block system; much better. It does require some...

    Possible to account for gage runout?

    Thank you for the suggestions, I'm considering all of them. Only because it's a cheap shot, I found a 5C lathe chuck mount which matches the registration recess and bolt pattern of a small 4-jaw independent chuck I have in the parts bin, if I can get the tapered holder to <=0.0005" that'll be...

    Possible to account for gage runout?

    The gage in this case is a 5C spin indexer, I'm using this to quantify the TIR of a sample of finished parts. The specimen holder is an internally tapered piece with a 1" OD which is held by the 1" 5C collet. The materialized TIR of the indexer, 5C collet and holder is 0.001", as measured with a...

    Mitutoyo digital indicator error question

    I have reset the origin after replacing the battery. I opened the back of the unit to see if there's anything to clean; it's way above my pay grade in there.

    Mitutoyo digital indicator error question

    I've got a Mitutoyo 543-472B 0.5"-0", 0.0001" indicator that's acting up, it's a long shot but, figured I'd see if anyone here has encountered this. What happens is the least significant digit will blink "E" occasionally, and the 2nd digit will jump to a "1" even if the gage is measuring in the...

    How to exit a dead end cut without moving the cross-slide?

    Sounds as if the cross-slide is the way to go, I'm good with that, thanks for the help.

    How to exit a dead end cut without moving the cross-slide?

    Yes, I could use the cross-slide, I'm trying to avoid that in order to save positioning time.

    How to exit a dead end cut without moving the cross-slide?

    I'm turning the end of a piece of finished round material to a reduced diameter. Once I reach the length of the reduced diameter feature, the work is done. The problem is how to get the cutter off the workpiece with out scarring it, and without moving the cross-slide, there are more than a few...

    Just had way too close of call on the DP

    My first real job was running a printing press, rule #1: no neckties, no long sleeves. Glad you are OK, and thanks for the DP heads up.

    What is a tear-free surface?

    This makes sense to me. I have to note though, microscopic, or any images, are more challenging to extract from inside a hole than they are on an exposed surface. Even with a borescope, it's hard to get angular views showing the landscape, so to speak. I could run the cutter on the outside...
