    Instead of any plastic I use a washer (thrust bearing washer) instead. I believe they are ground to .005, good enough for me.
    For the chuck to get stuck the washer would have to "stick" to the headstock and also to the chuck. I'v never had a problem but do apply a light oil to each side.

    Be careful when you mill the slots. Be sure you don't mill off metal from the critical seating surface. I don't know what your direct thread chuck looks like, all mine have adapters. From what I see, there's not a lot of metal to mill.
    Just my $0.02.

    I think Iím going to pass on milling flat spots on the chuck, there just isnít enough metal. Clamping a board between the jaws is easy enough.

    I am disappointed that the chucks arenít designed to have flat spots for a wrench.

    What about using an oil filter wrench? They come in all sizes.

    There are times that you don’t want to remove the piece from the chuck and put something else on the lathe. I still think using a spanner wrench is the best option. I did the board clamping until I figured out a better option.
    When working I had more money than time. In retirement I have more time than money. Love the time, miss the money.

    William, where did you get your spanner wrench?

    There are a couple of adjustable hook spanner wrenches on Amazon that look like they would work, one at $20, another at $50. Not sure I want to spend that much on a specialized tool, but I do cringe every time I put a board (or, true confessions, my knock out bar) between the jaws to remove my direct threaded SN2's.

    I don’t remember where/when I got this wrench. My guess it was in a lot of auction tools from many years ago. It is an adjustable Armstrong 4 1/2 - 6 1/4 spanner. My chuck is 4 1/2 diameter and fits perfect. I don’t know the diameter of the Nova chuck. I know these can be pricy and I would look at eBay for one. It would need to be the size for the Nova chuck body diameter. The other John Jordan (as JKJ would say) did a demo at our club and one of the things he stressed was never to spin the chuck on. Bring it to the spindle face and then tighten moderately with a wrench. He also used WD40 on the spindle threads before installing the chuck. I have been doing that (except I put some never seize on my spindle threads about once every couple of weeks) and have not had any of my chucks “stuck” since over 1 1/2 years.

    Everyone has an opinion. What was the reason given?

    I suspect spinning it too hard by big green Incredible Hulk hands could create a problem.

    John said that the chuck would never require more to remove it than to install it. I have been tightening my chuck by hand for the last year and half and it works. I have not had any chuck get “stuck” and zero problems doing it that way. Before I use to spin it on and occasionally the chuck would get stuck, sometimes worse that other times. No more.

    Logic says it would "probably work" work but the RP wrench uses a hole in the RP adapter that is not on the direct threaded SN2. I have Teknatool and RP chucks and the wrench.

    Or maybe a strap clamp?

    Home Depot Strap Wrench out of the plumbing department solves the problem with not having wrench flats. Cheap no damage solution.

    If it is just the chuck, I put a piece of scrap wood, may half inch thick, perpendicular to the chuck, tighten down the jaws and lever it loose.
