that means it can make 10 pointed patterns you can’t do with the deluxe set.

In reply to Don Carroll. No, they aren't compatible at all. The Spirograph teeth are much smaller. Different manufacturing technologies.

That’s how I feel. I can still have fun with the others! I remember how magical it felt as a kid when a spirograph pattern came to a perfect completion. Very satisfying!

BTW, do the regularly spirograph gear teeth mesh with the ones from Wild Gears? A video on the WG website says they have a different shape.

In reply to Don Carroll. Good heavens! Well, if you buy the hoop set and sacrifice one hoop, you can still use the other pieces to draw with! Have fun.

Thanks for the helpful reply. What’s most important to me is the diameter. What I’m looking for is a gear (teeth on the outside) with a diameter of about 5 inches (125mm). The Wild Gears “hoops” set seems to have what I need since it includes a gear with a 131mm diameter. (Close enough!)

I wouldn’t actually be using this for drawing at all (though I did love the Spirograph growing up). Instead, and this might seem strange, I’d be using just 1/4 of the 131mm hoop as a part for a 1/5 scale replica of a WWII German Flak gun as used on U-Boots. The gun had a partial gear that elevated the barrel.

In reply to Don Carroll. Do you mean diameter in inches or centimetres, or number of teeth? The larger number of the ring size is the number of teeth on the outside of the ring. So Ring 150/105 has 150 teeth on the outside and 105 teeth on the inside. Ring 144/96 has 144 teeth on the outside and 96 on the inside. Those are the two rings commonly included in official Spirograph sets, and they are about 3-3/4" and 3-1/2" (10 cm and 9.2 cm) in diameter respectively. Using a regular sheet of 8-1/2 x 11" or A4 paper, you can generally run any of the standard wheels around the outside of the ring with the #1 hole and stay on the paper. That was probably the consideration when the set was first designed. The new Fun Shapes Set which I haven't tried out yet has some different rings. I don't know the sizes. Wild Gears has much greater variety of ring sizes.

Can anyone tell me the outside diameter of the Spirograph ring? Is there more than one size?
