    From Jim Wilkins@21:1/5 to All on Sat Sep 30 10:34:29 2023
    At the second hand store another customer was buying lathe equipment so I
    asked him about trouble I'd had parting and he told me to set the blade
    about 0.020" below center instead of trying to exactly center it to clean
    off the tit before drilling as I had been doing. I just tried and it worked much better. The partee didn't fall off but was easily broken free.

    There was a discussion of that subject over on the Logan lathe list a
    while back . They were advocating a spring tool holder for cutoff so
    that it wouldn't dig in . I do the same as you , set my cutter just
    below center and it works just fine . They were all aghast that a simple adjustment will do the same thing as their spendy tool holder . Even got
    a few "That can't possibly work or I wouldn't have spent all that money
    on my tool." exactly as I expected .

    I've seen the below center cutting position suggested on various boards
    and groups. Winky's Workshop did some videos on parting including
    making a spring loaded tool some time back. I just skimmed the videos,
    but among them turning below center was also mentioned.

    I've always done it , just seemed intuitive to me . Now that I've
    stepped into the modern world with a qctp and a much more rigid cutoff toolholder I'm partin' shit off just for the fun of it .
    Please pardon my 'tude , I'm drinking to excess this evening in
    preparation for a drive to Memphis tomorrow . Twofold trip , doing
    repairs to a pottery kiln for a long time (35+ years) client and
    picking up our oldest g-daughter up for a stay with Grammy and Grandpa .
    We'll swap her for her brother in about 3 weeks . He wants to be here
    for Beanfest .

    They make a compound just for that . I'm not sure what's in it but it doesn't shrink as it cures/dries . I can get the info from the potter
    for you this afternoon if you'd like .

    No rush, it's for an old electric tube furnace I occasionally use for controlled heat treating. https://www.lindbergmph.com/light-industrial/1500-deg-c-heavy-duty-tube-furnace

    There are other refractory coatings.

    You know I have a kiln taking up space on my shop floor. It was free.
    I've goto to stop accepting free stuff... The plan is to steal the
    elements and and stainless shell make a small heat treat oven. I've
    been debating a either an combustible gas type or a positive pressure
    type. I hate sanding. For now I either heat treat with a torch or in
    the gas forge. Did I say I hate sanding?

    I think Sairset is the one my potter client used for some repairs .
