    Default Foot Powered Lathe (Spring Pole Type)

    Yeah, I know. I wanted another one, though.

    3D40C140-A8A2-43C3-96B9-5D9A67027137.jpg
    So I took a spike and cut it into two pieces which I ground to fine points on one end, and rounded over the other.

    46C16D3F-8F1B-4D45-A5BC-50CEFCAFCEEE.jpg
    Then I stuck one in a snug hole in one of the stocks. This is to be the fixed stock which will be at the left end of my lathe because of you put the fixed end on the right, the lathe will burst into flames and explode.

    Meanwhile, the sliding stock got its pin. It’s pretty important they match up, so I usd the fixed stock pin to mark the spot for the sliding stock. It worked pretty well, eh?

    118C8EDA-23E5-4363-8E0B-3AD447DA59F0.jpg
    The sliding stock needs a wedge to hold it steady. It helps if it’s tapered. Wait, isn’t that what a wedge is? Silly. Hehe.

    Add a cord, some blocks to lead it, an old bow for a spring, and a pvc foot stirrup.

    If you zoom in a bit, you can see it works fine, even with a goofy tool rest. The stirrup rather than a pedal allows the cord to move a bit, as do the blocks. It also allows you to switch feet. I’ll refine the tool rest, make something better and more adjustable, then relearn how to turn.

    And find my lathe tools. Ooh! And make some!

    Peace,
    Robert

    Did you drill for the points with a drill press?

    Did you shape the points by putting them in a drill press and holding a file against them?

    The points were made by putting them in a hand drill and spinning them against the bench grinder. Then I hit them with some diamond stones, still spun in the drill.

    I drilled the holes by hand, with a guide. Well, two squares and my eyeballs. I figure theyíre close enough for a precision machine like this.

    I'd be interested in seeing how you get on with the stirrup rather than a treadle.

    Where is the springy pole?

    I once tried to o use a bungee in place of the pole, not too well.

    How many lathes burst into flames and exploded before you switched the fixed stock to the right hand side? Was anybody injured in the explosions?

    I actually prefer it to the treadle style. The treadle is fixed, and the best place to stand is fixed, too. A treadle rarely works as good with both feet, at least any Iíve made.

    I had a foot powered sharpener at the old place, too, and it was where I developed the stirrup approach.

    1/2Ē Schedule 40 pvc makes good stirrups and bucket handles. Pop the bail off a 5 gallon bucket and slip a length of pipe over. A nice handle that lasts...

    Up in the rafters of the shed. Sorry. Iíll snap a picture today. It is an old, cheap bow I had, made from pvc pipe and fiberglass rods.

    If this goves up the ghost, I have a bunch of sticks and saplings to try. My last one had a laminated spring made from layers of ash glued up. Maybe Iíll do another like that?

    Iíll probably lave the pipe.

    I have seen three burst into flames. Iíve never seen an explosion personally, but I have seen a guy with a permanently messed up hairline from a piece of lathe shrapnel what scratched a wicked a crooked line down his part.

    Thatís what he says happened...

    I don't think that it has to be fixed.

    Wanna know the real reason I didnít use a drill press?

    I recently got a honking big Rockwell drill press, a gnarly floor model, so my bench top drill press is apart now. I thought to myself, ďSelf, you could change that chuck...Ē Then I made this little ball bearing supported center for the other end, and I started cutting up an old bed frame for the bed rails. Hehehe.

    Soon I shall be knee deep in the chips of erstwhile not round things! Wait, what?

    Oh, believe me, your brain will be thoroughly examined when it comes time to figure out which end of a metal lathe Iím supposed to feed my necktie into.

    Hehe.

    Iíve turned a bunch of wood, with electric and burrito power, but the metal lathe remains an accordion or violin, to me.
    I have to say, this pattern lathing is something Iíve never done, either.
    Thank you!

    I love the stirrup. That hadnít occurred to me. Might try it. My treadle roves around a lot. Either that or build something more substantial.
    I built a pole lathe over the summer. Lots of fun.

    One way to stop the treadle moving is to hinge it to the front edge of a board, then you stand on the board as you treadle.

    Promise youíll never ever come over and look at my lathe, okay?

    I must say, though, we used the same number of power tools.

    Pole lathers always walk around in circles, so watch for that...

    Okay, even with VERY dull tools (the skew chisel had a bit of, ahem, heavy orange dust, ahem, on it) anda ridiculous tool rest, the silly thing works. The wonkiness is due to pilot error, not lathe error.

    7957B3B6-7A92-4D3F-99B8-9C43B8A1AD92.jpg
    Upstairs is the spring pole. In this case, the pole is a recycled pvc pipe bow. The bow is reinforced inside with a progressively size stack of fiberglass rods. They are fairly common and simple to make, and shoot hard. 40-45 pound at about 28 inches draw.

    I don’t shoot it anymore, so it’s a lathe spring, now.

    The stirrup allows for switchstance pole lathing.

    Iím scorned by some traditionalists, but Iím all about the progression, Brother. If weíre not moving forward, weíre not moving forward.

    That was my second solution but it moves the treadling foot under the lathe and gives a very short stroke. To get a long pull on the cord it has to go out some way infront of the lathe. Works though. My next iteration will have a triangle of boards with one apex behind me and the treadle hinged there. Then Iíll be able to stand in a more normal position with a longer stroke.

    Well, being as I want to use my lathe to turn a nifty breech plug for the duck punt “gun”, I need to make a drive adapter deal to run the cord on, similar to what I’ve seen the bowl turners use.

    So, I went to work modifying the fixed stock’s pin on my custom metal lathe.
    26179C8F-BDF8-4070-A740-1A195DE5D48E.jpg

    The idea is to be able to run a bronze tophat bushing in the end of a fat dowel, and have it run against a washer on the stock. The other end of the dowel will have three pins to index into and drive the piece to be turned.
    55B7FF9E-F15C-4B8E-A918-B8952ECBD839.jpg

    So, now I just need to drill the dowel, countersink a bit for the bushing, screw a “bash plate” (washer) on around the edge, so I can tap it into what is to be driven, and set the pins (sharpened nails) on the other end. I aim to use turkshead knots either end to reinforce the dowel and keep the drive cord aboard.

    Peace,
    Robert

    P.S. I also eliminated the blocks. I wasn’t sure the routing would work without, but the stirrup allows a direct line from the bow nock.

    Feller I knew in Sth Australia had one base on an old foot powered dentists drill with a big cone belt drive to vary the speed. Pole lathes are fun.

    Okay.

    Much has been learned. Truthfully, this was always intended as a sort of beta test, anyway. It works way better than I thought.

    So. I aim to make a new bed and stocks, this time with taller stocks. Iím going to use bolts threaded through the stocks as centers, both for adjustability, and to keep them firmly in place.
    Also so I can spin a nut and washer onto the bolt and have a bearing ride on it to carry the mandrel. Iím also thinking to have the drive cord run around a permanent mandrel affixed outside the headstock...

    Basically, Iím just going to make a larger, more robust version.

    Then Iím going to make some tools. Lots of old sawzall blades and speedbor bits around...

    Peace,
    Robert
