Is the spread on your paddles still 60 degrees. If so do you see a problem with going to 30 degrees spread. If I'm thinking correctly this should give a 1 thru 6 on first half revolution. Then start back to 1 thru 6 on second half of revolution.  This should allow you to keep both paddles. In my mind it would look like two half spirals. But I'm not sure how this will effect the stroke on your lever arms. You may have to lengthen the levers and cut down the length of your paddles to allow for the shorter stroke. Not sure.

It would also allow you to place your weight further out on end of levers because of the gain in mechanical advantage on your shorter paddles.

Hi, interesting suggestions, thanks, nice to have options. Before I do anymore changes I should test it under load. Thanks again

Conservation of energy maybe a reason why this project could fail.

I am sure that many people have told you, that your machine can not be self runner because of "conservation of energy". And conventional physics teaches exactly that.

But you built it anyway and it looks like you have fun building the machine. The merit is in trying it in spite of the big hurdle to overcome. And if you can afford the build and if you do not become obsessed, no harm will com from it.

Greetings, Conrad

conservation of energy applies to a isolated system, this configuration could be two isolated systems, continuing to test

How are those guides for your rack gear working out? In one your videos it looked a rack was sticking a little on way up.

I have to watch your videos several times before I actually hear what your saying. My eyes are to busy studying the different parts. In your last video you asked about optimizing flywheel. One thing to consider is shape.  The bolts and holes in your flywheel will create more air resistance. At lower rpm it may not be significant but it's still robbing power.  In one of my projects I have  a 10" spoked flywheel. At 1800 rpm it was more like a centrifugal fan than a flywheel. I was able to shave20 watts off just by placing a steel plate close to the sides of the flywheel but not touching. So long story short a smooth flywheel would be a plus.

Hi, the guides are working ok, everything could be better.  Thanks for the info about flywheel.

There is slop between the gearing of the rack and pinion. There is no sticking at this time.

I'm not sure why you want to swap the small blue gear and large gear around. Do you not have the room to move pma shaft over and have blue gear driven directly from large pinion gear.

Hi, everything fits. I can test at 1 to 9, swap the gears and test at 1 to 6. This is just version 1. Thanks for  the help.
