Ok I thought I would start this new thread to show work in progress of a 36 x 45 Phi torus that I'm considering trying to build.

Essentially most current torus work seems to be focused on the 36 x 36 torus which by the math should have 12 nested vortices circuits each looping through the hole once.   This is too hard to build so close approximations are being made.

A 36 x 45 Phi torus may be the next best torus to try build as i think the math can be matched exactly.

I will attatch some images to show the math and current work in progress

Cheers

Ugg just wrote up more info on this build and it didn't post?!?
Hey ho will write it up another time
Will attatch renders of work in progress
Cheers
PJ

Alright :thumbsup:

Cheers Lynx
This feels good :)
Think I am on the right track
PJ

Russ - from your experience what thickness should I be using for the formers and the ring?  From what you have said the rig tends to try and twist so I'd like to try get this right first time.
I'll likely add those "bracers" you show in your latest design for added support :).
The torus I am making is 270mm outer diameter and 54mm inner diameter to match the approx. Phi proportions 5:1 that I mentioned in your thread.
I was thinking of using 4mm for the former and 5mm for the ring.
Cheers
PJ

Here is a .stl file showing work in progress

Attatched are notes on the dimensions I am using

Some lightening holes added to former

Russ - what tolerance did you use for the slots used for connecting the formers and ring?
I was thinking of allowing .5mm - eg if former is 4mm then slot is 4.5mm

Ok I have assumed 4mm thick for formers, 5mm thick for ring and plus .5mm for gap tolerances.

Model is complete and ready for printing :)))

I will attatch images and .stl files.
I opened one of the .stl files and found it has to be scaled up x 10 times as I was working in cm in 3DS Max.

I'll start printing tomorrow and start the build.  I have some ideas on how to roughly time / fire the x 6 separate windings - i will share this with you soon.

Cheers
PJ

Started printing today
All going well :)))
Ring and two formers done
My printer is at work so no more prints until Monday
Should get three to four formers done a day
Getting there
Here is a photo of the ring and formers
Cheers

hey Pj, sorry i was away from the forums for a bit. looking good! any questions you need answered? i see some above but maybe you already have got them resolved? nice work!

~Russ

also i see you had to leave the holder out of the center.
its to tight there. so what you did there should work. wires should stay in pace with some help :)

~Russ

Hey thanks Russ

I've got one more former to print today then framework is done.
Yes no holder in the middle which should be ok. I'm happy for the closest point of contact being in the centre of the torus.
I'm struggling to find a local supplier for magnet wire so may be couple of weeks before I can wire this up as last time I got it from the USA :(

Yes couple of questions:
1/ do you use an electric glue gun to connect the pieces?
2/ I'm planning to use 24 strands of AWG 24 (approx .5mm) for the wire bundles which is about 4mm thick - is that what you would use?
3/ Do you know of any good magnet wire companies in Australia or who could deliver to Australia pretty quick?
Thanks
PJ

1. yeah that works well, just a small dab will do... ( my parts fit tight)
2. i used 23awg 24 strands and worked well!
3. i have know idea unfortunately... google is your best friend :)

looks good!

Thanks Russ

Ok framework is finished
Here are a couple of photos
Wire comes today or tomorrow
Have an idea how to wire it to best match the math which i will write up soon

Haha aaaahh I'm at work now so not much time.  In general - I have x 6 wires in this torus that match up with x 3 lots of 124875 paths running one way (positive - Ed's north magnets) and x 3 lots of 124875 paths running the other way (negative - Ed's south magnets)
Like a 6 cylinder car the timing may play a critical part for best tuning / performance.
When you look at the torus render I did earlier and you can see the 124875 paths and how they are offset from one another- the idea is that if 1 is considered the timing point for each wire then when I hook up the amp positive and negative outs to the wires I have to try offset the connection position to try replicate the offset in the math....
This would be much easier if I had lots of expensive electronic gear where you could advance or retard timings of signals etc but I don't so I have to try do it purely by using different connection points on the wires.
That is about all I can write as need to get back to work.
Hope that gives some Idea of my plans
PJ

did you watch my videos from years ago?

Some of yes
You had a 3D grid of the vortex math.
It didn't excite me overly so did not think I would go through all the videos.
Do you think I am missing something or do you have a better idea?
PJ

Looks like about 3m length per wire - 3DS Max gave a digital length of 2.95m and winding with string gave about 2.8m but string probably bad idea as too thin.

So 6 wires x 24 strands x 3m = 432m of wire.

Russ is there an idea you are wanting to share that might help with how I'm planning to wire and time the firing of this coil?
Did you come to the same conclusion as i have in your pervious work?
I'll be starting to wind the coil in about a days time so any further advice would be much appreciated.
Cheers
PJ

no i have no back info at the moment. doing some research and letting things flow...

Ok
I'll keep flowing too
Will hopefully start winding tonight
