Ok the pics seem to work so I 'll show a coil in closeup. The wires were stranded on a special machine. Coil former is pvc drain tube- the exterior plates are plexiglass and the whole stuff is glued with acrylic to pvc glue. Very solid bond but has to cure overnight.
Coil cores are soft iron wire, could not find the welding rods here.

Wire sizes are 0.8 mm for the power wire and 0.6 mm for the trigger.
The wheel will run at 200 to 220 rpm. I tested the strength.... and the wheel disintegrated at 350 rpm so that is limiting the performance.....

The magnets are glued to the wheel but not just on the rim. I made small wooden blocks to conform to the inside of the rim and with a flat surface to hold the magnets. the tape around the wheel seen so often is not very good because if a magnet comes off it will impact the coil nonetheless. I use rubber bands to secure the magnets. This way if a magnet comes off the glue it will make a loud knocking sound. that is warning enough to stop the machine.

For the winding of the final coils I made another jig with a mechanical counter to count the turns. I found that I could not get a decent winding without a layer of tape between each layer of wire. Each coil holds about 300 feet of wire, the impedance is 1.6 Ohms on the power wires.

I can charge a 100 Amp/hour gel cel type battery that was given to me in a "dead" state (8.5 Volts) and could not hold a charge. Now it can be charged to 15 volts and will run a car headlight bulb. For the primary i sometimes use NiCad cells leftover from my model helicopter. (a 30 cell battery at 40 volts). That battery was completely dead before I used the bedini on it.

Next step is a metallic wheel made on a lathe and milled with slots to hold the magnets.

This is definitely worth building, I have learned a lot in the last 6 months.

Thank you for sharing your work with pictures.  I think that a Bedini replication is in my near future.

@bourne, thank you for sharing your taping tip as well.

Thanks to all of you for your kind reply.

I would like to know if anyone has experience with swapping of batteries on these systems. I know it is not supposed to work but Mr Bedini must be doing it on the big machine he has built or it would be worthless.
I think a lot about the radiant energy phenomenon and the experiments seen in bedini's ENERGY FROM THE VACUUM DVD seem to indicate that it is really a RF phenomenon. The radiant spikes, when expanded on the scope, are really very fast oscillations. That is why there is a skin effect where the energy can leave the conductor. See the demonstration where Mr Bedini lights a small neon bulb between ground and the plastic cover of a battery under charge.
To my laymans view it seems that the famous bi-filar coil can become a low impedance tesla transformer. Because the number of windings on primary and secondary coils is identical, there is no extremely high voltage...Could this be a reasonable theory? Anyway this still does not explain the battery charging effect.
 The thing does work as indicated -unlike some other internet-based projects I have seen- and every day I work around it seems to uncover more interesting questions.....I cannot see more energy out than in yet though.

Hi Albert. Nice work! good to see someone else replicating and testing. Heres some pics of some recent test machines I have built. I havnt been able to do many tests yet as I am waiting to get some decent batteries. The window motor I converted to the Bedini cole circuit and looks promising. I have to build a timing wheel to switch between running and discharging back into the primary. In regards to swapping batteries, it is not recommended to swap the charged battery to the front end on the simple ssg circuit. That circuit was designed to teach the basic principles. It is far more beneficial to use the charged battery on another load to see the benefits. What you will want to replicate is the cdpulser setup, (capacitive discharge) and it can be found in a few places on the web. There are different versions, but they all do basically the same thing. The simplest has a timing wheel that dumps the energy stored in the capacitor into the charging bank at a set rate. There is also a 555 timer circuit designed to automatically do this.

Look forward to seeing some more of your work!

P.S. I made my coils identically to yours! PVC sheath, acrylic top/bottom, tie wire glued as a core. I had to twist all my wire by hand however, that was not fun

Hi albert

About the 'swapping batteries', here is my take on the matter;

When Mr Bedini shows the large machine in the DVD you see 2 sets of very large cells in the main workshop area with the machine on a bench in a smaller room. Now, I have presumed that the batteries driving the large machine are on the shelf 'below' the large machine. The two sets out in the workshop are swapped between; one set under load (lighting the lights in his workshop) and one set being charged (cylinder cells in the DVD)
After watching the DVD several times I now think the Bedini machine is a "power magnifier". Swap 2 sets of batteries between charge and load. While the same is happening with the 'supply batteries', one of the pair driving the large machine while the second one gets charged by a smaller machine which has it's own pair of supply batteries which again could be charged with an even smaller machine.. and so on until all you need to charge your smallest machine is a single solar panel

Does that make sense? That's how I would do it. Either that or use the available shaft power to charge the second supply battery conventionally.

I think the swapping front to back will only give you the shaft power as spare. Swapping 2 batteries between charge and load will give you use of the battery power and the shaft power.
It all depends how much charge you can get out of the coils.

I only have a single bifilar coil to work with at the moment so I can't say if another coil (trifilar) means half the charge time. I do hope so.

As for the glue mentioned in your last post.... Don't know ! My max RPM has only been 230rpm so the superglue is still holding solid. An Epoxy type glue would be my first thought but I would have to see the spec sheets on its performance.
I remember somewhere in the Yahoo groups monopole forum, somebody posted some calculations of an 8oz magnet coming off a 20cm diameter rotor spinning at 10,000rpm.

Conclusion..... Do not be in the same room!!

If I remember correctly it was something like 3 times the joules of a colt 45 shot at close range !!

You also mention the tolerance of the magnets. I had the same thing, but fortunately I had to buy a minimum of 50 so I just picked the best 32.
Have you thought about weight distribution? do all your magnets weigh the same if they are different sizes? I think that will make a big difference at 3000 rpm.

As for switching batteries every 1.5 seconds see below.

One of the first Bedini device switch between batteries, in the ENERGY FROM THE VACUUM DVD, he show the device, the main rotor move another one and this other rotor is the mecanical switch used to switch the batteries, the batteries switch on each 1.5 secs prox.

Hi The One, I am sure you are wrong. that machine is the capacitor dump machine. It is constantly charging the large capacitor which is then dumped into the charging battery every 1.5 seconds. Separate from its supply batteries. Using the commutator as shown in J Bedini's 1984 book (reprinted in Tom Beardens "free energy generation")
