Hendershot Replications

[thx1138]

What's missing?

What is missing from all of the schematics and drawings and the builds that don't work that is in the builds of Lester Hendershot and the Aho build that did work? Look at the attached paste up and see if you can see it.


Then check out the video at the link from 18:30 to 26:00 paying particular attention to what is said at 25:25.

hendershot gen

hi im new to this form and I am trying to build a hendershot gen and was wondering if anyone has yet produced 230v on the output and if so do you have a copy of the wiring diagram ? any help would be grate thanks ben

Magnetic vortex spinner

That is a very nice video, I am sure the Hendershot Mk1/2 both had a ring magnet and it should resemble the one shown in the video, that is, radial magnetization. This is actually what Hendershot found, (what I think is that) he discovered the armature of the earth inductor compass started to spin around on its own when it was placed inside the ring magnet. The switch in the model plane was just to interrupt the wire connected to the motor, but the magnetic spinning field was always present. The next step was that Hendershot managed to replace the armature with a mixture of coils and magnets that picked up this magnetic vortex and amplified it into an alternating current which grew stronger through oscillation and positive feedback, which initially only worked when the inner coil and magnet were aligned north-south.

They said Hendershot made a toy plane and the propeller turned by itself, I wonder if this is how he done it.

Hi, I wanted to know a few things?
1) The load is only resistive or can be of a different nature?
2) someone who has achieved, he has found a stable and durable?
3) undergoes external interference from other devices like cell phones?
4) what is the pattern and final componeti to make it happen?

Magnets & Iron Ferrite:
Passive:
1. Iron Filings:
Went back to the fishtank with a whole range of alternative presentations to the setup as suggested but made no headway with self resonance.
Tried a thinner plate both vertical and horizontal, steel rods long and short, ball bearings out from the Pole faces of the horseshoe but only one item of note.
The ball bearings had a preference to stick to the face of the twin coil faces rather than the Magnet.
Unfortunately the iron filings are too far away from the action to see anything of a field that might suggest something.
Initially the Coils were secured by bolt to the plate but in subseqent experiments, all 3 of Magnet/iron bar and twin coils were free to move individually.
A voltmeter attached to the coils showed anything up to 3 volts being generated by various movements.
There was no specific area where I could say that the voltage induced was able to continue doing so with a self vibration/oscillation.

I am still amazed at the non ability of the magnetism attaching itself to the attracted metal body - WHY?
This must be why you can join ring magnets with the same polarity with a slight twist and this is clearly demonstrated with strong and large Neos.

I recall having read that when using iron fillings, you change the magnetic field because you're adding small magnets. I suggest using some other method of visualizing magnetic fields around objects. I don't have any resources on that, at least not yet.

2. Magnetic Viewing Film:
Second run is with magnetic viewing film and shows a rather strange pattern from the back of the horseshoe and a concentrated line down the middle but that is all.
There is a bolt through the middle here attaching to a metal 'L' mount at the rear of the shoe.
Not able to view much at the Pole points with any movement.
This horseshoe is quite strong as I am able to induce movement in the small compasses from a distance of 28".

Have since read 'thx1138's note on the Antique Coin coils and will be setting up a central arm that is able to seesaw between the two coil pole faces.

Active:
Just in case it is an outside resonance that is responsible for the 'Resonator' working.

From the Wesley Harper document:
"The conditions are that the thickness of the iron magnet must be proportional to the power of the magnet, and the neutral line, or the line of change in the polarity of the iron, is nearer or more distant from the magnet according to the power of the latter and the thickness of the former."

Unfortunately have had to leave the tests there as we are in a serious Drought and have just finished an operational rainmaking run with a zero result and as a consequence two new and with different concept rainmakers are on the drawing board and should be operational soon.
Talk about imbalance, the Tropical Monsoon has been a record breaking one but the centre of the country is as dry as a bone and have only had one good rainfall month in 8 months and kind of - well - serious.

Have been reading Leedskalnin's 'Magnetic Current' but find it difficult to reason and considerable time is required to go through his tests.

Home-made Magnets are in form stage and have worked out a way to magnetise using a twin coil setup.
Don't want to use Neos if I can help it - this is not a horse-shoe magnet in the true sense.
Will get back shortly with the 'Active' results.

N20Wolf,
Thankyou for your Post and information from your Forum.
Please note that the horsehoe Magnet from 'Magnets and More' is NOT a true Magnet and the picture is displaying where the magnetism comes from and is sitting on top of the larger NEOS in front and is a small Neo which happened to pull out of the metal face and which measures 5mm diameter x 7.5mm long.

Thank you for the link N20Wolf.
I see that my Dailymotion magnet plus ferrite rod Wesley Gary video is discussed there on page 45.
YES - illustrating the instantaneous series-parallel magnetic field reversals within an armature or coil core or ferrite rod, which might be considered to arise about a neutral zone, and where the armature/rod may be overwound to generate electricity with negligible mechanical effort once the mechanical attraction force has been balanced by springs etc.

Now consider that Hendershot's coffee tin-can sleeve cores are also similarly overwound cores as hollow equivalents to the Wesley Gary armature or the ferrite rod in my video, and additionally resonantly tuned.
(Sleeve cores are so much more efficient than solid cores.)
Also consider that the sleeve field might similarly be induced to reverse itself through phased 12t pair winding impulses with respect to a polarising and gapped energising ring magnet field concealed beneath each sleeve core ???

Were ring magnets concealed beneath the board supporting the sleeves in that generator Lester demonstrated empowering his radio circa 1950 ?
No ring magnets - no self sustaining output ?

Cheers ............... Graham.

Magnetic vortex spinner

I have seen the video and have tried to quickly replicate the device but until now without any real success, but that's mainly because of material mismatch I guess. At some moments the armature does want to turn on its own it seems so I only need to build a better version.

One thing is for sure you cannot use magnetic material for the outer armature, only copper, this to avoid attraction by the neo magnet.

Anyone else had success replicating?

I suspect that the battery is being drained through the copper because of the almost short circuit that is being created.

This effect is most probably what the Hendershot Motor used (the device that preceded the MK1); the coils inside were also shortcut according to the Utility Engines document, and the coils wounded around the ring magnet were used to start the motor running. The document also mentions some copper-iron cores were used inside the windings to overcome any counter force that could result from the interacting magnetic fields and thus kept the motor running. The switch was most probably a momentary contact to DC pulse the coils on the ring magnet to get the motor running.

I think this was the type of device Hendershot built for his son's small model airplane and this one could well have had some type of battery and push switch to start it.

Capacitors & Carbon

Hello Adam Mizer,
Yes, good information.
I mentioned this earlier with the Jorge Resines document that there is a note alongside the Aho capacitor drawing stating:

"Common parrafin - microphone carbon sealed against moisture at ends of coil could be substituted" (sic).

Hard to read but something like that.
A good source of carbon granules today is from water filters and all you have to do is open up and wash the granules and they vary considerably in how fine the granules/powder can be.
These are normally thrown into the garbage bin but can be obtained from any company that do swimming pool maintenance.
Other sources for Carbon are from the art shops where they are used for drawing (Graphite) and in different grades and also if you are on eBay you may find solid arc carbons from old movie projectors and actually have tins of those here and are Copper covered.

Have two huge Sangamo caps coming that measure 220 x 75 mm, 25k uF at 100 volts and should give ample material for home-made varieties.
Don't believe anybody else has manufactured their own caps as yet but is a fun exercise and kind of awesome to find that yours match Lester's very closely to the 7,800 pF and can be tuned initially with the wooden paddle-pop sticks.
Don't recommend going outside this capacity initially as we need to stick to the original parameters as best we can and time for experiment at a later date.
Don't think loads of capacity is of interest here, more frequency related in establishing the 50/60 hertz pulse.

Sled vernier is finished and about to mount on the baseboard for further tests with the 'resonator'.

capacitor

Hi, I' ve been trying to follow along a bit with you guys.
I know your on the magnet stuff now but the foil capacitor has been on my mind for a while.
A friend of mine pointed this out while I'm on another project.
With these foils and being right there with the antenna type section a coating of polyurethane and graphite on the foil would make a super capacitor and can be done easily.
Then a coating of buffed on graphite may give the graphene effect, in this video he shows the charge of the cap seemingly holding and discharging at a slow rate which I thought may be of interest.
This could easily be applied here.
Lead (graphite) from a pencil, or graphite powder for key/locks.
