Treadle Lathe Articles

March 6, 2016 by Bob Easton Leave a Comment

A lot of people come here interested in the treadle lathe I built.  To make information finding a bit easier, here is an index / table of contents for the lathe articles.

Video overview

  • Show-n-Tell 1
  • Show-n-Tell 2

Design Thoughts – Plans – Construction

  • You’re Gonna Build a What? – first thoughts
  • Plans and Lams – source of plans and laminating lumber
  • Parts – mostly metal parts that you’ll want to order, not things you’ll find at the “home center”
  • Parts Update – Stephen Shepard is now selling a set of metal parts that match his design
  • Wheel
  • Makin’ Parts – cutting curves and scratching beads
  • Wordless Wednesday – cutting curves with my very lightweight “turning saw”
  • Feet – for the book-matched foot fetishist
  • Gams – Mortises and tenons for the legs
  • Resume – after a break for other projects, come back and work on the tailstock
  • Mount the Wheel
  • Bearing Blocks – purchased parts and scraps of Walnut
  • Puppet / Tailstock – fitting the spinning metal parts
  • Head End – bearings and shafts for the great wheel & the headstock
  • Treadle and First Turning – making the wheel sort of round 🙂
  • Spindle – completing the headstock (almost)
  • Drivin’ It – the belt
  • Tool Rest (#1) – and a new drive pulley
  • Adjustable Tool Rest – improving on the original
  • Machined Crank Details – THANK YOU Roger Davis! Roger made this wonderful crank.
  • Compilation – Josh Delmonico compiled all of these posts into a single Word document.
  • Tailstock improvement – a simple knock out bar
  • New Banjo and Tool rest
  • Sanding Station

In use

  • Carving on a Turned Object – the first of many turned objects

Treadle Lathe – Machined Crank Details

January 30, 2014 by Bob Easton 7 Comments

Lathe builders in 1805 didn’t know Roger Davis. They’d just have a blacksmith make them a simple crank and be done with it. I didn’t know Roger either when I built my lathe. He saw the blog entry showing the (pathetic) wooden crank I made, in the absence of a blacksmith, and suggested it wouldn’t last long. It didn’t. He then made me one that will never fail. It is solid!

Roger Davis is a fellow Hoosier with the good sense not to move to New York, a frequent visitor to the Sawmill Creek forums, owner of “a very complete machine shop” and self-proclaimed “lack of good sense,” an aerospace engineer by education (Yay Purdue!), former high school teacher (physics, cemistry, algebra), a builder of scientific instrumentation (start to finish) as his paying job, a builder and user of muzzleloaders as one of his hobbies, and variously proficient in gunsmithing, blacksmithing, woodworking hand tools, A&C furniture, cooperage and who knows what else. Bottom line: a generously good guy.

So, why am I telling you all of this? Josh, from the previous post, wanted more information about the machined crank, as did Matt in the comments on the post about Stephen Shepherd’s kit of parts.

Photos and a drawing tell most of what you need to know to make one. If you have the metal working equipment to cut a block of steel, cut a slot in it, drill accurately, and tap some screw holes, you can make one similar. For what it’s worth, the distance between pivots was simply an estimate (a little more than a tenth the diameter of the flywheel) and has worked very well. Roger didn’t specify the size of the cap screws, but they look to be 1/4 by 20 by 1 inch long. The only other thing not shown on the drawing, that’s very visible in the photos, is a dowel pin that retains the crank pin. The retaining pin is probably not needed on this particular crank since Roger built it to such close tolerances that the crank pin probably took several tons of pressure to seat as a “press fit.”

When installing on the flywheel axle, be sure to go back and forth between the two screws, as they each affect the other’s tightness until they are really tight.

This crank has been very solid. I’ve got hours and hours of use on the lathe and ZERO, Nada, NO slippage from the crank. It simply works! Thanks again, Roger.

Treadle Lathe – Compilation

January 28, 2014 by Bob Easton Leave a Comment

One of this blog’s followers, Josh Delmonico, compiled a Word document that includes many of the posts for the Treadle Lathe category. The result is a single document that describes building this lathe.

I browsed through it quickly, and found that it covers all of the construction related posts. There are a few posts not included, such as ones published after construction that are related to some of the things made on the lathe. Omitting those is logical for someone wanting to build a lathe. The focus is on the build.

The included web links work too! Josh captured the photos at sizes that fit comfortably. You can see larger versions of most of the photos by clicking through to the actual blog pages and then clicking on the images.

For someone wanting to build a similar lathe, this is a GREAT compilation that gets all the construction related material in one place. Highly recommended.

THANKS JOSH!

Download >>>—> Treadle Lathe DOCX (about 8MB)

Update (1/31/2014): Josh updated the document to include the recent post about the machined crank. All build details are now fully up to date.

PS: For those (like me) who don’t have Word or abstain from the MS suite, you can find a variety of DOCX readers with your friend, Google.
