Im about to try and make one. Love you videos. What length and shape blade do you recommend one the 2 1/2 hub with 3 blades?

@gwheyduke 7 ай бұрын

Three blades, each about 4 1/2 - inches long would work fine. You can make the blades 2 inches wide. Longer blades usually begin turning sooner in lighter winds but rotate more slowly. I've made them 6 or even 8 inches long. Good luck with making your whirligig.

Is there an issue or risk I should say with the sawblade hitting the metal hinge? Great video! Thank you

@gwheyduke 29 күн бұрын

If the fixture is set up correctly, hitting the hinge is unlikely.

What thickness of wood are the blades ? Do you cut them to the desired thickness on the table saw ? When cutting the grooves in the hub, how do you get a wider cut than 1/8" ? My table saw has a 1/8" kerf. Love these videos ! Thanks !

@gwheyduke 11 ай бұрын

Thanks for your comments. Yes I use a table saw. The blades are about 3/16-inch thick. Originally just used to run the hub through multiple passes to open up the slot. Then found a "cheap-o" wobble dado blade for $20 bucks, it's thinnest setting is 3/16-inch. Works pretty good. Some guys are making their own dado stack by putting two thin cutting (.040) blades together sandwiched with 2 pieces of card stock to come up with the desired thickness.

I'm still trying to hone in on my settings. I obviously wasn't center as mine looked like the one you showed that didn't have a through cut on the rear. Another issue I'm having is, I'm using 1/8 for my whirlygig blades. With one saw blade the slot it too small with 2 the slot is too big. How are you getting such a good fit? Thanks in advance. Love your video

@gwheyduke 9 күн бұрын

Getting the hub slots the exact size can be difficult. You can try different saw blades. Some are thicker than others. Some builders stack two blades together to form a specific thickness dado cut. Another trick is to simply run the hub through the saw blade multiple times to open it up.

@timhicks2866 Жыл бұрын

Is there an advantage, other than less material for blades, to having 3 blades over 4?

@gwheyduke Жыл бұрын

For simple whirligigs the answer is no. For airplane propellers or Wind turbines the optimum number of blades is determined by the aerospace engineers for each particular application. 4 blades are probably used most often with whirligigs because it's easy to cut a square hub with the individual blade slots while keeping them exactly 90 degrees. Also with four blades they seem to balance out easily. 👈 hope this answers your question.

Can I buy a bunch of 120 and 90 hubs? Don’t have a set up.

@gwheyduke 28 күн бұрын

What size hubs do you need, and how many? I have a just a few left. You would need to make your own blades; the slots are approximately 3/16-inch width.

@matthewyoder2085 9 ай бұрын

How did you determine the height of the table saw blade? Thanks for the great info!

@gwheyduke 9 ай бұрын

Usually just hold the blank hub close to the blade and move it up until it is slightly below the center hole. Maybe about 1/8-inch to 3/16 or so on this size hub. Leave enough wood to give it some strength.

These hubs are used to make Whirligig propellers with three blades. You can use them to make wind spinners and various types of whirligigs such as a windmill or airplane. 🙂

Please can you help a useless female 😂... Is this possible to do using say a mitre blick and hand saw... I am desperate to make a small scale whirligig but do not own any power tools, apart from basic hand drill etc thank you... Super info vids

@gwheyduke 9 күн бұрын

You can make a propeller hub using a hand saw and a miter box it will work. The slots for your blades don't have to be a perfect angle, it will still work ok. Starting with Square hubs make it easier to cut the slots by hand.
