Treadle Lathe – Puppet / Tailstock

In yesteryear they called it a “puppet.” Today, we call it a tailstock. Same purpose, different names.

Earlier I mentioned that I’m aiming for a more modern interpretation. It is in jest that I forgo the old world costumes, and in practicality that I seek a smooth running contrivance.

a short digression … There was a time that I imagined having the “village blacksmith” fashion some parts for this lathe. A strange thing happened on the way to see the smith. I discovered he left long ago. The quaint little village I live in is intentionally quaint. I came here over 30 years ago as a convenient place to live while I pursued employment in the corporate, private, free-enterprise world. I didn’t move here because it is a quaint little village. Yet, about that time a town council was elected with the purpose of keeping the place little and quaint. There is no development here. No new people arrive (or are welcome) to help share a constantly increasing tax burden. Long story short, the smithie was one of the first to recognize the peril of perpetually increasing taxes and he left. Word has it he’s in Cody Wyoming where there’s plenty of smithing to be done and people who actually appreciate industrious private enterprise.

Many replicas of old time lathes want to use a large screw with a sharpened point as the tail center. I wanted a bit less drag and smoke! Live centers all seem to be attached to tapered fixtures. How would I support one of those? Some time ago, “TrialAndError” briefly mentioned using a “morse taper socket” in the lathe he built. It wasn’t until a photo of drilling the puppetweek or so ago that I searched for such a thing on eBay and discovered they really exist.

(drop back one post to see a list of parts)

The morse taper socket I bought is simply a 1″ diameter chunk of stainless steel machined with a #2 morse taper hole, and then hardened. It is 4 inches long and includes a closed slot machined crosswise near one end. I assume this slot is used in applications where the socket moves within a quill. ¬†Beware when buying this piece. photo of completed puppetYou can find them in the $30-$50 range on eBay, or for $9.70 at Amazon. Shop around.

Drilling the 1″ hole through my puppet was a task best done on a saw bench. It is low enough to allow the right ergonomics of a very long auger in a hand brace. The short swing of the hand brace made for slow boring, but also made it easy to check constantly for accuracy.

The result is a very tight fit, requiring a block of wood and rubber faced mallet to drive the socket into the puppet. If, I find it moves under turning pressure, I’ll add a pin through that slot.

    Bob, That slot is for a drift to knock out the center when it becomes stuck in the taper.

    Norm, You can tell I haven’t used this sort of device. Makes sense. Thanks for the explanation!

    Great stuff Bob. I remember that post on Trial and Error and I too have found these sockets. Honestly the hardest part was knowing what to call it to even search for it in the first place. I really like this method as it is a simple and clean install though I am seriously considering pirating a full spindle assembly from a modern lathe so I can have one part that functions as my pulley for the belt too. I think I’m just going to have to plunk down some cash and experiment with that idea to either accept or refute it.
