As it was raining yet again today grrrrr. I thought I would knock up a gravity wheel out of different parts I had laying around and will try some of Archers Unique ideas out.

Here is progress so far.

I have gone for 4 poles rather than 3 as the wheel I had already had the slots there. I may knock up a new wheel to mount the 6.

I used 8 small linear slides, one for each small arm. These will get linked together as shown in the last picture so when one side is in and the other is out.
I have mounted the bolts on the connectors at various heights and I am going to use the old metal flat Mecanno as the links. This saves on height and should not look too messy!

I quickly got out the good old Blu-Tac to mount some ball bearings just to add weight.

Each end connector, gets a plate slotted in where the ball bearings are, will hold a Pole with a magnet on it. Will show that later as it comes along.

was going to use Mecanno strips to join each slider, but then had a thought about using Hacksaw blades instead.
These are thin, strong and lightweight. Bit of a devil to cut and drill, but work a treat.

Have done a quick video also to show how smooth these sliders are. There is no weight on the ends at the moment and they still slide, with the odd one sticking every now and then .
I think it is a good idea to reduce the friction in as many areas as you can while building it up, because trying to do this later will be just stepping back as such.

I will add brass poles next to each polycarbonate slider mount which will the added weight and fix some magnets on the end.

Here is the video of the progress so far.

Was going to leave the Brass Rods till next weekend as I am away during the week working as usual, but came across this metal weld glue that is fantastic stuff and dries within minutes. Saves alot of time making up brackets to mount the rods and rock solid when set.

I cut the Rods to 50mm, drilled and tapped each end with a 3mm thread and then are mounted on each connector.
The over all length of each rod end to end is 340mm and the movement is 25mm on the sliders.
 

Here is a video showing how the extra weight now gets the sliders going down where they should be.

Time to start on the Stators.
Two arc's cutout, one for top right and populated with magnets, second for bottom left hand side with magnets yet to be press fitted in

Approx placement of upper arc. Obviously not sticking to magnets!

Brass did not turn up today, so could not make my links for the weights.

Did manage to get the stator magnets mounted and also have to now place it on a bit of wood as the base as do not have a big enough piece of Polycarbonate. Had to double the Rotor Arm magnets to get the strength correct.

One thing is very apparent as others have said the middle bearing receives a lot of pressure from the bottom row of stator magnets and I think I may have to change this to a tougher design. Or may shorten the brass arms to reduce the weight and drop back to single Rotor magnets on the arms.

Archer released a couple of videos this week and they can be found at http://www.surphzup.com/gpage1.html1.html

So decided to get the balance right I would strip all the magnets off the wheel and leave one arm in place.
I then milled out a couple of brass 2mm thick brackets and cut various lengths of Brass Rod to add weight to the arms.

I have also now doubled up on the center bearing and now NO play!!!, so that is better but had to lift the Stator plates up higher.

I have spent a fair bit of time adding different a different weight onto the end of the extension arms by varying the length of the attached brass rods and also by adding/removing extra magnets.
I can now also remove/add stator magnets to try get the approach/exit walls where I want them.

So now a lot of fiddling and tweaking to find the sweet spot of all combinations. It will be a busy weekend!

More to come.

PLEASE NOTE.

Sorry I am not posting the results of my experiments as this would take too much time.
But when I have something I can shout about and that works 100%, then be assured I will post an update.
For now this is just a Blog as such of what I am working on.
