    Don't drag me into this! I'm studiously NOT picking on Jerry. My ex, maybe, but not Jerry.

    This MUST be the Bi-Weekly LET's pick on Jerry day!

    I do enjoy this banter, especially when it stays on track and doesn't descend into name calling.

    Yeah, true. But the statement ended in ellipsis, which by definition means that something that should/could have followed was not stated. There was likely to be a third.

    I had an ex wife who was quite proud of her extreme stubbornness. She was the only one who thought it was positive.

    And have the incessant need to always get in the last word.

    The reality is MOST power feeds do not convey the rate at all, and stuff still gets made.
    Sigh.......

    No doubt that is so, no doubt that is so.... Your opinion is, of course, not binding on the rest of us. I find it reasonably good to have some general clue about the feed, which in my case is easy enough with a clock and a crank at 0.1" per rev, whenever I consider it appropriate.

    If I provide myself with a power feed, I trust it will not excessively discommode you if I also provide myself a table of approximate feeds corresponding to various settings. I admit I will lose no sleep over any internal discomfort that table may cause you or others, however.

    I had mentioned, as examples, that many manufacturers of serious industrial mills, for instance, provided built-in feeds of known and settable rates.... and that the feed rate in IPM at different settings is commonly listed in a table for lathes as well, to assist in deciding what rate will be good with the tool you are using.

    You may feel free to ignore those, it is your right. You may cover those heathen idols up, or even go and rant at the graves of the designers who foolishly thought that providing tables of feed rate was useful.

    If you do that it's best integrated with some form of motor braking. Easy to do.

    I had exactly that on my prior lathe which has a separate electromagnetic brake. Not only did it work well, it saved my ass a few times With care makes for really nice threading stops very close to a shoulder, closer that you can get without significant pucker.

    OK, yeah, I was thinking about post #8 which suggested exactly that. I'd do that in a heartbeat.
