    Opps! . . . I was thinking of the Nikon, Pentax, etc., bayonet lens mounts requiring a twisting motion. Totally forgot the term applied to the lathe tapered mounts I used years ago. Age and cross-culture technology. . . sometimes an unfortunate mix! LOL

    I’m very interested in converting my screw thread Sheldon lathe so will be watching with interest. Many thanks for the dimensions.

    It does require a twisting motion, not the chuck but a holding ring (the bayonet??)

    If you can't make it precise make it adjustable.

    There is a reason why pond scoops were invented.

    Takes a little longer but you never even have to get your machine in the mud, for that matter a pond scoop can be used in standing water.

    I'm talking about this...Precision Grinding a Hardened Shaft with an Improvised Toolpost Grinder-pond-scoop.jpg

    Not a 3-point hitch rear scoop.

    I guess that works on a drag line.

    I think in the case above access is the big issue since it's in an established neighborhood and an excavator on mats was the only way to get equipment in there that would do the job without tearing everything up. Then again they said it was a rental so it might be that a track hoe was the only thing that the property manager knew about.

    I've seen a video of that same recovery operator cleaning a bigger pond which was worse and he didn't get stuck so skill is a big factor in success.

    It is a drag line, it can also be pulled by a horse or mule, or a tractor running on higher ground. the side tubes take handles like a wheelbarrow which are used to control depth and to steer it to some degree.

    I have a pond that is silted in on one end, and a vehicle will bury itself within 50 feet of the bank most of the year. I have seriously thought of using a pond scoop to dredge the shallow end.

    The fish stocked in the pond have tied for state records in the past so I really don't want to risk a kill off by lowering the level just to dredge one end.

    I have considered suction dredging, that's a story for another day....
