My spring pole lathe using a bungy (inner tube) instead of a springy pole. This shows all the parts so you could make one yourself.

That's looking fantastic for your second bowl. You might fix your string wear problem by dropping it down between the ways, or by moving your treadle a bit forward to pull the string away from the ways. Love your little bucket size rocket stove!

I really like this. It captures the simplicity of the machine, and is really fun to watch. Compared to other power tools, there's really nothing stopping someone from building this. You could probably build one in the woods with handmade tools... but using an actual pole rather than a bicycle tire :)

+Rab Beverly Absolutely, this one was built with hand tools. You can build them from a log as well which is how you would do it if you are in the woods or if you have a log and no lumber. It is really easy to build so go for it. I need to update this as I have changed my setup some. I now use an actual springy stick.

Nice video thanks for sharing and explaining so well! You could put a clothesline pulley where the rope rubs so it goes over the wheel instead of rubbing and fraying on the wood.

I ended up putting a dowel back there on centers just like the lathe itself which works great as the string can be anywhere on the lathe and roll. Also, I have since moved my lathe outside and have a longer treadle which also takes away the rubbing and allows a longer stroke.

Rollers are a good idea though i guess . Better to just attach the string threw the middle if possible . if it does not hit the tredle high up enough then you can drill a hole in the tredle and pass it threw then attach to another hole on the end and make the end of the rope into a triangle configuration . ps . im thinking to make a tube lathe so im not a expert .

Hi Glen . thanks for the vid . how about passing the string threw the two pieces that make up the lathe bed ? just attach it to the treadle as you normally would .
@gingram81510 жыл бұрын
Passing the string between the ways still had rubbing problems. I installed the roller mechanism which is just a dowel that is on centers just like the spring pole lathe works. I have had no problems with this and have not had to replace a string since.

I was speculating that if the cord were first rubbed with paraffin or candle wax, then it would be protected from chafing against the wood;
@gingram8158 жыл бұрын
+Thomas Loo I imagine that would help, but you are still going to go through cords if it is rubbing. I installed a wooden dowel that rolls as the string goes by. That worked great as it took out all the friction. I have since moved my lathe outside where I have plenty of room so the cord doesn't rub anymore.

@rickschuman29268 жыл бұрын
You treadle should be 42 inches long so you get a proper stroke and plenty of leverage. This generally gives enough height to clear the ways. My lathe has a single way and the poppets straddle.
@gingram8158 жыл бұрын
I agree but there was no room in the shop for that. I have since moved it outside with a longer treadle and it works much better.

Interesting design, how do you find the tool rest works? Every pole lathe I have seen/used for bowl turning has a bar type tool rest on a perpendicular bracket...
@gingram8159 жыл бұрын
Andy Collier I have since switched to the bar type for two reasons: the bar is longer and super easy to adjust. There is less time moving the tool rest. I do think the more conventional rest in this video is a little better for spindle turning depending on what you are doing.

Do you use the specialized pole lathe bowl tools? Have you ever attempted to use a standard bowl gouge like would be used with power tools to hollow a bowl? Seems like they'd be easier to find, but I wonder if they'd even work?
@gingram8157 жыл бұрын
I haven't tried a modern bowl gouge using the traditional hook tools instead. I think a modern gouge would be difficult to use because of the mandrel (drive shaft) in the way).

Very good job! But the cord come in wrong way belonwn the work area. I saw that it rubs against the wood of the base and makes friction. I suggest to modify this. Greetings
@gingram8156 жыл бұрын
Yes, in that setup, there was no way to correct that. I ended up installing a bar behind the ways that rolled which eliminated the friction issue. I ended up moving this outside and used a longer treadle which fixed it completely along with giving me more power and more rotations per push which was great.

@gingram8158 жыл бұрын
+Thomas Loo No, the lag screws do not move. I grind the threads off of the ends of the lag screws, polish is smooth, and put a dab of oil on the screws to reduce friction. Then the wood spins freely on the screws.

it's now 2017, are you still using this lathe, have you altered it at all, and have you made a lot of bowls? I have not checked your channel yet.
@gingram8157 жыл бұрын
I am still using this lathe though I am in the process of building another one right now. I'm improving a few things: the most important is I'm making it longer so I can turn longer spindles. I moved the lathe into a shed since this video so I have more room. I also want feet with more splay so it is more stable. I'm also making this one with more room under the center so I can turn a wider bowl if I want. I can put up a video of the new one when it is done. I have not turned that many bowls, a few dozen.

thank you for the reply. have you looked into live centers? I'm about a week away from building one and I'm stuck between live and dead centers
@gingram8157 жыл бұрын
You may get a little less friction, but you are not going to be reaching turning speeds like those of an electric lathe. My understanding of live centers is that they are mainly helpful for high speeds. I have not tried it so can't tell you for sure though. I will say that there is so little friction on the lubricated dead centers on my lathe and they are so easy to install, that I can't imagine there will be a significant advantage to a live center. I'd recommend spending your time/energy/money figuring out the optimal spring, treadle, and tool rest setup as those are much more important, in my opinion.

Was watching this and wondering two things. Could you not just put your rubber band under the table?? If this would work then you could do this in a space like mine with no overhead space or attachment point. Also could you not run the "power" stick through your mobile bit and then attach the wood to that? Turner rope on one side, project on the other? Thus freeing yourself to work the face of the boll?
@gingram81510 жыл бұрын
I don't think putting the rubber band under the lathe will work. You need to have the rubber band pulling the treadle back up and simultaneously reversing the spin of the work. I don't see how you can do both of those with the band going down. There is a more complex model that may satisfy you needs that Roy Underhill teaches at his school. It is apparently a French (though someone else said German) design. Here is a link to a picture www.handtoolschool.net/wp-content/uploads/2013/07/PoleLathe_adj.jpg. I'm not following your second paragraph. You'll have to explain that a bit more.
@DouglasEKnappMSAOM10 жыл бұрын
Glenn Ingram, ND YA, I thought the second part would be hard. I will draw it. imagebin.org/319552 It does not matter where the rubber band pull comes from because it is turned into rotational force. Just try pulling on the rope with your arm from under instead of up (just a test without rebuilding it. Might need a friend there to do it with you.). It will turn.

Douglas E Knapp I was thinking last night about those sewing machines that you run with your foot. I bet you could take one and use the foot part with a flywheel to run a lathe!
@gingram81510 жыл бұрын
Douglas E Knapp I see what you mean. That could work but you would have to configure the treadle so the 2 don't interfere with each other. Flywheel lathes have been done and are awesome, but they are much more difficult to make because you need to install bearings and such to tight tolerances. I gave it a shot once and it didn't work at all. I probably needed better bearings and something was probably a bit crooked. You really can't mess up with the spring pole lathe and the price is right. On your design for faceplate turning, you can certainly do that. In fact, I tried that very thing but you get into bearings and tight engineering tolerances again. My home-made version would not handle the torque required to turn a bowl. I use it to power a sanding disc.

Glenn Ingram, ND I make bows and I can see how it me what you made looks so easy but the reality is that it takes skill and a lot of failing to get it right, not even talking good. Bows are like that too. You can just forget your first two because you WILL break them. Part of the learning curve. Thanks for sharing your failures. It opened my eyes to the possibility of the failures. I had not even suspected yet that you could fail at making these things.
