@Smudge:  would a "140 mm / 60 mm / 20 mm" Feritt ring magnet also work? It seems to be difficult to get disk magnets larger than with a 100 mm diameter.


With the 140 mm ring magnet the 100 mm circular water tube would be in the middle of the ring (between the 60 mm inner diameter and the 140 mm outer diameter).

Conrad:
   D/l the user manual pdf for that unit and refer to page 56. At the top is says you also have a Power Amp built into it. Be ware of it tho. Do not over drive the RF amp as you will destroy the pre-amp side in it. Your SG says it will do max 10 W to an 8 ohm load. You will be doing a 50 on the RF side. Start out low voltage and low amplitude to get the best results.

@thay: thank you for the information, helps a lot.

I tried to find the user manual PDF online, but no success. Do you have a link? Or you could attach the PDF file?

@thai: Sorry, I thought you have found a PDF user manual of the RF power amplifier from China. But it is helpful that you read the function generator manual more carefully than I ever did.

I could 3D-print a circular tube as specified by Smudge, see the attached photo. My Creality Ender III Pro which I bought recently for EUR 230.-- managed the difficult bridging when printing the hollow tube without supports. Clearly, I did not want supports inside the circular hollow tube.

If an experimenter needs a similar circular tube I am willing to print one and send it by mail. The experimenter either pays me EUR 1000.-- or simply asks nicely.

Now I need to know, whether (140 mm / 60 mm / 20 mm) ring magnets which I talked about in my post above will be good for the replication (instead of disk magnets).

   Conrad:   I wonder what would happen if the tube was filled with liquid mercury, and a spinning vortex of mercury could be created.Would it fly off by itself...  As some antigravity space craft seam to use mercury for their drive systems.  Sorry for the off topic. Just some thoughts that came to mind. As it seams to me that as inward vortex is what can draw extra external energy into a closed system.

Hi Conrad,

That magnet size would be ideal.  I like your tube construction by printing, hope it works out OK.  I have created a spread sheet for the input circuit solving the equations but it is quite complex and does something silly at the resonant frequency.  It is a math problem (something like dividing by zero) which needs sorting out.

@NickZ: Mercury poisoning would happen!

@Smudge: Thank you for your calculations, it is not urgent. Attached a drawing of the setup I am thinking about.

Hi Conrad,
That's a great graphic and exactly what's needed (except it doesn't show the toroidal coil wound on the ring but I am sure that will follow).
Keep up the good work.

You could also use a hexagonal cross section which would be easier to print. 3D printed objects are not really watertight so you might need to refill from time to time. Treating the printed tube with a flame for a very short time, only melting the surface, might seal the surface.

Interesting thread BTW.  NMR is an interesting topic.

@skywatcher: interesting, I will test the watertightness of my printed tube. On first sight and with a "blow-test" my tube seems to be tight, but I will do a test over days.

@Smudge: after a long contemplation, I decided to abandon a build and further tests. My electronic skills are not adequate and I do not want to go to the public workshop where I could set up the whole thing because of the Coronavirus (I am an old man who should not get the virus).

My very little contribution is the attached PDF-file which contains links to the necessary equipment (RF amplifier, capacitors, magnets). And if someone wants a 3D-printed circular tube, please send me a PM with a shipping address. I am prepared to produce and ship a few for free. I can also send the .stl file which has to be fed to the slicer for your 3D-printer (to produce the g-code). But if you have access to a 3D-printer you would want to designe the tube yourself.

@skywatcher and all experimenters: my 3D-printed tube is not watertight.

After a while at the lowest point (if the tube is suspendet vertically) water dissipates through the 1 mm thick PLA (which consists of 0.2 mm strands stuck together by heat).

Such a tube has to be treated with paint. Heat, I guess, would distort the shape of the tube before melting it uniformly.

Skywatcher taught me an important lesson.

Conrad, your contribution here has been greatly appreciated ,I am contacting a few who can carry this open source effort  forward here. also asking about simple methods to seal the fixture [shellac or] that would not effect the experiment.
tremendous gratitude

Chet K

 PS, there are a few more builders topics coming to the forum.[one water Fuel topic too [heating..or ?

I have made good experiences with heat treatment of 3D printed PLA parts. Not only for sealing, they are also looking better sometimes after heating the surface. I use a small gas torch (size like a lighter, but with a blue flame, you can get them in 1€ stores) and if you do it right this will not distort the shape, it's only necessary to slightly melt up the surface. You need the right lighting angle to see the PLA melting. As soon as it gets shiny, you have to stop heating. After this treatment it should be watertight. Maybe you should increase the thickness of the wall a little bit. 1mm is very thin. Maybe 1.5 or 2 mm would be better.
