Mitch: I think I have a few hubs sets left and I could make up a set of bird wings for you. Contact my [email protected] address and let me know what you need.

So glad you enjoyed the video. Thanks for the comment. Cheers!

I don't but you can find a similar plan on Cherry Tree Toys website. cherrytreetoys.com/goose-whirligig-plan/

Yes - It really is amazing!

Thanks for the memories, it's great to have some history here!

Hmmm difficult to hear

In all my experience I've never had a nail, the size that I use (6 penny) bend in the wind. Although I suppose that if you had a rather large propeller and a small nail it could conceivably happen.

Yes, that's a good idea, then you have an accurate center point.

Thanks for the comments. You can make a replacement piston; I think those were aluminum with 1 ring. Some were made with no rings. You would need an accurate drill press or mill to drill the wrist pin hole. I set mine up on the mill and use a Palmgren vice on the table to hold the piston on its side, with a V block in the jaws to center the piston. When you machine the piston blank in the lathe, it will leave a tiny "pip" in the center. You can use this mark to center the drill bit over the piston, then just move the piston under the drill bit with the X axis hand wheel to the desired position of your hole. Use a center drill first, then an under sized drill bit (-.005) then ream to final size. Probably around 3/16" or 4.5mm

PS. There's a new Enya SS.40 cylinder/piston set on eBay right now for $44.50

@gwheyduke Thanks. There is a mail strike in Canada at the moment, so I can't order anything from Ebay.

Glad you enjoyed ! Thanks for the kind comments.

Well that's an excellent question. Bigger is usually better, also the further back the tail fin is from the center of the pivot point the more force it will have to turn the whirligig into the wind.

Thanks 👍

Make sure the bottom of the boiler is clean, it might be burning something in there!

@@gwheyduke already did that, i cleaned it top to bottom so idk, i might just convert it to run on fuel tablets or something

Best of luck with your whirligig propellers! 👍

The 2 to 1 gear ratio is between the crankshaft and the cam shaft. You can see them in this video of the engine running. kzbin.info/www/bejne/eGLZdoZ_atCJoaM The brass gears are actually located behind the flywheel.

Yes absolutely, this has been done.

Yes, well the water leak wasn't a real problem as I had simply shorted out the intake and outflow of the cooling jacket. I put oil in the case before starting. Working on setting up a true water-cooling system with a pump.

Thanks for the comment. Best of luck with your whirligigs.

Yes that’s certainly an option. Of course it would then require the purchase or making of some threaded rod to fit the nut. On the whirligig these were made for wire cut from discarded yard signs was used.

@@gwheyduke Threaded rods are available at most hardware stores. And if you don't want part of it to be threaded, you can slide a brass tube over that section.

👍 good idea, I had thought of gluing some rubber cut from on old inner tube to the mating surfaces of the discs.

The demonstration was intended to explain all of the possible angle and blade configurations available in order to animate any given kinetic wind driven mechanism as well as the mathematical geometry required to determine blade spacing relative to hub disc size.

That's great. Thanks for the comments.👍

@@gwheydukeLove your channel & looking forward to seeing more, dude 😊🤙

It's made in my shop. Threaded a piece of brass rod to fit the pressure release valve opening, drilled a 1/8-inch hole through it and then soldered a short length of 1/8-inch K&S brass tube to accept some model airplane fuel line.
