AB Hammer's gravity and keel grid
« on: January 05, 2009, 07:16:18 PM »
Greetings all

Here is my favorite grid that I use in wheel math for figuring out if a wheel is worth a build or not. It is a simple design but what you do, is to make a clear copy of it and lay over your drawings. Up rite position to count the gravity line + and - then you turn it sideways with the + side up for the keel count and the you add all the +'s up and then the -'s up and if you have more plus than minus you might have a design worth building. Other factors come into play after that. Frictions, reactions, and so on. Unfortunately my grid doesn't help with this but experience does. You can do more angles with the grid for a closer count of pluses and minuses. The grid is set up for clockwise rotation. Just reverse for counterclockwise rotation.

Here is one of my other grids P-Motion like you talked about on the other string.

Here is a list of all the strings I have started. There is several designs in them to look at.

 I have just posted another video on Youtube of a design that almost ran. But if you look closely and use the grid you will see where the Keel factor killed it.

I am sure you will enjoy it and open up allot of questions and possibilities.

Alan hows things..good i hope ;)

Just a quick question, how many wheels have you built altogether?.

Chad.

Thanks Jim

Greetings Chad

I do more effects testing before I build a wheel even though some can still be called wheels. So I can say when you add all those test and wheels together they would be about 65 to 70. This evening I am finishing up a joint project and hope to have good news. Some others that I am doing, take a fair bit more time to build. This means that I am manufacturing parts to be used. My one that has hit 200 rpm but has the timing problem. I am having to forge out special parts and I have to have a calm time when I am working on something that precision Then I can test it to see if I am correct. Others they just take time to build, and I don't get that much time outside of my living work. I write on forums during like my lunch break like I am doing now or the beginning or end of the day.

I will be posting a new youtube video in about 2 weeks to a month and also a new string. Just a early notice ;D

To show how the grids work I overlaid the my grids on MT24 in both directions to calculate the positive points and the negative points and here are the pictures of the results. for a clockwise turn it has a total of a negative 17.30 points that it won't run. But it would make a better reaction counterclockwise with only a negative 10.20 points. But still proves to be a non runner.  (Forgive me for forgetting to put the r on lower.  :-[)

 Also thanks to Bill of http://www.orffyre.com/ for all his great MT drawings, they are clean easy to check.

The lower picture is sideways for counting upper and lower counts.

 I am bumping the grid for those who need to copy. This will help them figure out to build or not. It only helps to show placement only it does not account for reactions.

Here is another design of mine, that tends to show over balance but it will not spin due to the Keel factor. Just another experience of what we have to overcome in this game. This one was using pendulum shifters for the hammers.

Working or not Alan, you do build some beautiful stuff. Keep going mate, good luck.

Here is something of interest in relation to secondary oscillations.

Note that the flywheel and slider powered by a pendulum of 20 kg have a combined mass of 150 kg. One would think that there would be very little movement, if any, but the simulation shows otherwise.

Also take note of the chaotic behaviour of the device.

Have fun
