Sorry man.

I posted comments about this fine tool usage to Rast instead of you.

You can see by how many times I had to apologize last night and admit I was wrong that I was in rare form and a little pre-occupied (migraine).

I did mean those misplaced compliments though!



Now I can go back a page and "catch up on my soaps!"

C U in a few.

You did not miss very much.. But entertaining none the less.  You should check out the post with searl vid links in them.. Highly interesting. Well the vids are interesting.. Not the post..LOL

@ Dirt, Shak, and various others (sorry, Pure used up all my research resolve for the day here)

Thanks for trying to help with the ramp/wall thingy!

Sorry if I seem to be tilting windmills here, but I see these as lessons in common sense (even if/when I screw up the terminology).

They don't teach it in schools.

Ever climb a water tower?  The ladders on them are vertical.. Or ever go inside a submarine?  The ladders there are also straight vertical.. Just some examples for you.. There are 1000 more.

Sorry man, he was quoting my not thoroughly explained retort. I meant a ladder that could be brought to the wall and not one already built into it.

My poor explanation. Go figure, stoner that I am.

Here's an idea utilising the SMOT concept Archer has demonstrated. I've already posted a basic idea of it but I've added to it.

As previously stated, my idea is to have a swinging weight within the arm, hinged such that they will drop on the downward swing, thus adding momentum to break the wall at the end of the run. As the arm starts rising gravity will cause the weight to fall back into the arm. I have included a lip on the arm cavity at the hinged end of the weight which prevents the weight from going perpendicular to the arm. I believe this should make the action of the weight falling back into the arm have less reverse motion against the wheel.

There are three arms per side (six in total). Please note that the opposing arms on each side are not positioned directly opposite eachother in relation to the hexagon but in a way that the arm on the falling side of the wheel is always positioned slightly above that on the rising side.

I know this idea has it's flaws, such as the weights falling back into the arms on the rising side (the worst place to get "feedback", but bear in mind that when the wheel is started, these can be started in from around 12 o'clock. The first rotation would be the most important, assuming the swinging weights can add more momentum into this wheel then they remove on the rising side..

Why use two sides? Well, it's hard to tell from the pics but I have the magnet arrays out of sync by 5deg on Side B so each other arm thro ugh the cycle hits the ramp and the wall at slightly different timings. These seperate arrays would need to be shielded in some way obviously. Unfortunately I'm not currently in a position to test if this change would help but if this wheel is going to work one way or another it just makes sense to me to try to throw the balance out as much as possible. I know the arms are already not "directly opposing" but the outer ends of them are still at 60deg to eachother. The non-opposing arms simply work by shifting weight inside the wheel. If the changed timings don't have any advantage then it would obviously be easier and more cost effective to use just the one side of the wheel and one magnet array.

There will be two posts after this one so I can show all three pics. This one will show "Side A" - the side of the wheel that is moving anti-clockwise. The next one will show "Side B" - the other side of the wheel. The third one zooms in on the swinging weight concept and explains the design of the arms.

Welcoming all input/feedback/ideas (yep, even yours PP).

@exx - enjoy the greens

EDIT: I forgot to add another reason for using both sides of the wheel - depending on scale, total number arms etc. the swinging weights could pose a danger to the next arm...

EDIT 2: I should have also mentioned that aside from making the retun in the upward cycle easier, the lip in the cavity also protects your precious magnets from getting mashed by a swinging weight. And I failed to mention that the weight should be a heavy, non magnetic material.
