Anyone have a suggestion for quality, straight-leg, lathe dogs in small sizes (under four inches)? Ebay yields nothing.

I make My own on the rare occasion that I need one. Large hex nuts drilled and tapped on three flats and a drive pin welded on one of the remaining flats and some set screws and ya got a dog.

Type in "2511" for the search.

Simple. Done. Most less than $10.

Thank you. However, unless I missed them, those are all bent leg dogs--I need straight legs.

Whoops. I completely overlooked that point in your OP. My apologies :o

To be honest, the only place I've seen them is in the Schaublin catalogs for their 102 lathes: http://tinyurl.com/n6n4ep Click the downloadable .pdf and look at the bottom of page 13. They list 6.5, 8, 10, 12.5, 16, 20, 25 and 30mm diameter straight-leg dogs.

I don't know about quality, but they are below 4" and straight-legged :)

Cheap or quality they all work the same. Bent tail dogs can be heated and straightened with a little blacksmith work. Home made dogs work well too. A friend of mine made a et that looked dandy. The oxy cut them from teel plate scrap and fettled them into a pleasing shape. The only thng holdng you back from a set og lathe dogs is either a misplaced notion that "quality" is somehow important in lathe dogs or lack of determination to make a set. Which is it.

That said, I bought a cheap set of bent tail lathe dogs some time ago. Once in a great while I use them and they work great. Much as I run my mouth you'd think I woulda made my own. Nope. Mr Hypocrit here.

The right angle drive dog is optional - you can also use a long all-thread in place of a bolt to create a straight legged dog. Drive it thusly:
