This time 10 RPM, one (1) RPM, so I needed to build a 1:10 ratio reduction, the wheel is 255 mm in d., and 25.4 mm is an inch, a 1 inch, drive that 10 wheel, rubber 1" wheel, a 1" faucet washer, exactly 1" with an 1/8" hole, a 6mm I.D., a 12 mm face, a 3mm screw centered in the 1/8" hole, looked about right.

Just looking at it I thought the same thing. Oh Jim did you carry the 1 and divide by the square root of 9?

Happy to hear the wheel turning was a breeze.

Jim,

Would a groove in the rubber washer keep the wheel centered? Not getting a picture in my mind as to how you are applying poer to the wheel.

Bernd,

Here's an awkward shot. The drive wheel is 1/8" thick. The width of the 'big wheel' is 3 mm. It varies about 1 mm through the rotation. It's very tight as the drive wheel is in constant contact with the big wheel. I couldn't go with a wider drive wheel as it would interfere with the seats travel. You might see that I had to cut down outer centering washer due to that interference.

Jim,

Ah I see the dilemma now. Sure is a tight squeeze.

Hi Jim, I'm late to the party to post, however, I have been checking in on this project.
My 2 cents worth would be, could you replace the otter washer with a metal flat one, and use a flathead countersunk screw to give you more rubber wheel width, and less outer washer thickness. I hope I'm making since here.

Thanks Bernd and Lou,

Lou, I did end up swapping out that outer washer on Saturday night with thinner smaller diameter washer that I made out of ABS. I also mounted the power unit on the skew plate. Pulled apart a couple ballpoint pens, and used the springs to push back the plate for the cobbled adjusting method. The big wheel turned for 7 hours overnight and I finally got tired of checking for drift. I think it'll do.

I'm glad you found a suitable idea.

After a month and a half of waiting on LP to show up to ride, it's almost time to put a fork in this one. The tuning plate to grip the 'big wheel' worked out very well. I had to add the 'red' bearing caps to give the chairs free movement as the wheel transitions through it's path. Here is the power unit installed without the utility shed.



I constructed the shed using the lapboard technique that I came up with on the RR clubhouse in an earlier scratchbuild. The roof is built as a single piece with the center 'shelled out'.

Here's a shot from the rear with the support struts added.

The blue barrier wall is actually scrap plastic that is printed as 'support' for another project. It also makes a good barrier for junkyards and sea walls. The overhead LED lighting really made this blue look wild!

One of the first riders was 'Little Rocketman'

The 'fleet' was in town, and the guys were happy to ride along.



The postal clerk hopped on the ride to lessen the stress of pigeonholing mail.

The forum is acting a little wonky so I'll stop loading pictures, but didn't want to slight our new operator.

I think the last step will be to add the safety straps from keeping these folks from dropping to the ground.
The holes are predrilled in the chairs, but the LP's needed to get on the wheel before I could lock them in.

That looks great. When does production begin? I bet you would sell more then the units on the Walther’s sight. What is next for your carnival?
