One liners

This style of electrical grounding clamps make good lathe dogs. All you need to do is add a short driver rod to fit against the chuck jaw.

One of those small adjustable Dremel chucks fitted to a length of tube with a spinner makes a neat little pin vise.

A small magnifying lens mounted to your prick punch will make marking out a bit easier. Use a bit of heavy copper wire as the mount to allow for fine tuning the focus.

A sawed-off toothbrush head held to the carriage with a magnet will keep the lead screw free of swarf.

A tea ball makes a great constrainer for cleaning small parts in solvent.

Fitting your fishtail gage with a tiny V-block will make holding it square to the workpiece much easier.

Liquid electrical "tape" applied to tweezer ends will make them tacky and prevent small parts going "sproing".

Soft, self-adhesive foam weather stripping applied at the edge of the workbench will make a forearm-friendly fence to prevent small parts rolling off.

great ideas here

Pictures don't do the ideas enough justice. Thanks Marv!

If you would like me to expound on anything, just indicate which ideas and what further explanation you would like. I'll try to answer your questions.

I think I understand them all well enough. The drive dog I had to think about a little. Are you holding a centre in the chuck and then clamping the ground clamp onto the object you wish to drive?

Yes, exactly. With the work held between centers, there are a number of ways to drive the work. Most "dogs" consist of something that clamps to the work; drive force can come from a pin projecting from a face plate mounted behind the center. Sometimes the pin is integral to the dog and fits into a slot in the face plate.

When I need to work between centers I like to have the 3jaw mounted. A piece of steel clamped in the chuck is turned to a 60 degree point. This approach guarantees that the center is perfectly aligned with the rotation axis of the lathe spindle. If the stock I'm turning permits, the chuck end of the stock is drilled to accept a Loctited pin that is driven by the chuck jaws. With no projecting dog bits spinning about this approach is much safer than the conventional dog. Of course, if that technique isn't possible, I use the dog shown in the picture.

Pretty cool, Marv. This suggests a number of different approaches to making a whole set of lathe dogs that solve the age old problem of 3 jaw chuck runout. A given set would be custom for just that chuck and it's custome worn scroll.. But it's really just an afternoon's work of relatively simple machining. You color code each set for one specific chuck. When the price of a new Bison chuck makes that approach out of the question this approach comes to the rescue. Ed Weldon

I guess I'm not understanding your "set for each chuck".

Since you turn a new point on the center each time you mount it in the chuck, only one is really needed. The dogs only transmit rotation to the workpiece so they can be used with any chuck.

Perhaps a photo of the lathe dogs mounted would help clear it up for those of us with less imagination... Otherwise, I think you have some humdingers there!

Perhaps you can puzzle it out from this photo of a more conventional lathe dog in use...
