    But to clarify, I am setting up to grind out of round and bell mouthed bore in the dead hard spool without the benefit of flood coolant. The vac attach effort is an attempt to both cool process and have some control over the mess - which does not need to be all over Jig Bore.

    The bore incidentally fits on the large central journal of the new input shaft - which was made oversize for the purpose

    Default Getting there on Jig Grind set-up

    Thought I'd better show this before covering it up with my wheel dressing rig

    Losing the camera for a week - stay tuned

    Some progress on dressing set up for jig grinding attachment. Looks great but did not get to use it as Precise died and I bored and honed this spool

    I see some typos in captioning - pretend they are not there

    Default Grinding Thin Woodruff Cutter Thinner Without Turning Blue

    Flood coolant helped.

    Spin index up on blocks, going to town on B&S #4 Universal

    Part of the milling on the Superior Hone mandrel is a thin slot that engages a tab on the mounted stone - I suppose to limit stone's ability to twist and bind up in mandrel.

    Looks great. Not familiar with this type of hone.
    Does it float a bit?

    Not that you would notice. I suppose the part was intended to float a bit. Have to admit I have never been around a Superior Hone in use until today, so have no idea of how they were applied

    John, why do you have to hone it after Jig grinding it?

    John, it took me a couple of readings to realize that you were line boring the steady rest (jaws), not demonstrating the use of a steady rest in line boring. I think?

    Yep - instead of wondering where they (the arms/jaws) were 40" out from chuck, just make them perfect by line boring (same bar used in the mill to fix the apron years ago)

    I spent several hours absorbing as much of this thread as I could last night. You work shows the ability to approach each problem with a jig or tool if needed to do the job. It's becoming a rare talent due to CNC. Building a jig usually uses a lot more time than the machining does on the part but your time spent is rewarded with the finish product. Today's labor cost don't usually allow work like your doing but I know why you do it. You are now being rewarded for all those years of the grind by now being able to work on your terms. I don't know , you may have always had that option. A good setup is time well spent. My gramps taught me that in working with him as a kid. I hope you are enjoying the lathe. You earned it because it's evident it's something you live for. My old Cincy has the middle leg damaged like that. I think somtimes that happens when they miss a mounting bolt or the grout hangs on when lifting it. Mine still had some concrete grout hanging on it. Or a drop damage. Sorry: My paragraphs and spacing are jamming all together when I post. Don't know what's going on.

    Thanks for kind comments. The doing is enjoyable, but the thinking / planning is what keeps the 78 year old gray matter percolating

    I spent a couple of weeks reading this thread off and on. (Mostly because I wanted to savor the skill and craftsmanship detailed here.) I must say: great work, John! Your ability to build jigs for every situation and the amount of thought you put into the efforts displayed is enjoyable to view. Any updates lately?

    Age (80 come the new year) and heat (first cool days of "fall" finally dragging in now) slows things down to a crawl, but still getting a little OD grinding done on tooling to support head stock during initial rework. Summer inactivity just turns one into a weakling as far as handling things like 80 LB shafts

    Thanks for kind comments

    Head stock "mandrel" in place - its about 40" long and the largest diameter is 3.125"

    B&S grinder did good

    Idea is to support this mandrel near the ends on the Jig Bore table so I can work from some fairly decent area (the pair of bores far from all the weld repair distortion) to reestablish the vee way by tilting the head stock at 45 degrees

    "Internal Cat Head" with its four "jaw" screws steadies up that end with the off center 6 1/8" bore (cap not installed here)
