    I would have thought that you'd want the cutting force directed down into the bed, rather than up into the toolpost screws... I'm also not understanding how parting upside down is less stressful on the machine, could you explain?

    But so am I.
    The eccentric Parting tool is installed in the toolpost upside down (in the front of the lathe) and the lathe is run in reverse.
    Not that its important--apologies for being pedantic
    warm regards

    Hey don't apologise ! I didn't realise that the Eccentric parting tool was intended to be used in the front tool holder.

    My thoughts were "screw on chuck, blade jamming", particularly after having seen someone having a parting blade jam and the chuck unscrewing and the amount of damage that it did.

    In their blurb they state to use it in the normal way if using a threaded spindle.

    With all this talk of various tools holding methods, in regard to shims for packing, an old style (can type) car coil is a good source of small, thin steel shims. Great for small tool holders or tool posts.
    Something else that no one has mentioned either is never throw away your broken centre drill stubs. They are great for making small, special tools. Its a lot easier to make a round hole than a square one.

    Hi Guys,

    Its surprising what good use bits of broken HSS can be put to ! I've collected a fair bit over the years. The most useful use has been in the fly cutter that I made. It is my go to milling tool, very handy for using those bits that would otherwise get thrown in the scrap bin.

    Just thought I'd fill you in on what I decided.
    From LPRtools I bought a straight holder and a couple of 1/4" HSS blanks. I was encouraged by the support in this thread and did my first grind today.
    I ended up buying an 8 inch bench grinder and a white aluminium oxide wheel. My goodness! What a difference it made to grinding! I could never work out why I did such a crap job in my attempts at sharpening drills. Now I know.

    Ironically, the multiple nylon bushes that comes with the grinding wheel are loose enought to make the wheel wobble. So I used the wheel to grind the HSS tool so I could turn a single bush to stabilise the wheel. I can see how the hobby of machining creates its own needs to perpetuate itself.

    Cheers.

    Good to hear its going well, and thanks for reporting back with the progress.

    If you haven't already noticed, while the white wheels are great they are also really soft (which is why they work so well) so its easy to wear a groove in them. If you haven't already got one pick up a cheap wheel dresser to use when you really need a flat wheel. One of the single point diamond ones from the land of COVID works fine for me but there are other options such as abrasive sticks or the Tee shaped ones covered with lots of smaller diamonds. Generally I find I can keep the wheel flat enough for most things just by working the different parts of the wheel as you grind so that it wears evenly.

    Thanks for that, I should have added that I did buy a diamond wheel dresser as well. Got a decent one from Carbatec. 'Tee shaped ones covered with lots of smaller diamonds.'
