Mark and all,

I just obtained this 5.5 inch cement pouring tube for fence posts.

Are we still using that formula for the length of the tube versus the dia  --
L=(dia x pi)/6 ??

Most of the videos and or shots , I see, show the length  almost the same as the diameter.
So with 5.5 inches with that formula , I get 2.878 inches high.

Have I missed something??

A free source of cardboard tube is your nearest carpet shop.
Carpet role tubes are thrown away on regular basis!

Mark , Chet and all.

I agree with not using PVC pipe as there are numerous mention of it in some of my Ham radio -home brew antenna articles (winding coils for antennas) where they state that PVC has many contaminents in them - mostly carbon etc. so don't use them.

I also found a source of heavy cardboard type tubes at Home Depot--used for pouring cement down and around fenceposts and deck footings and such. The smallest dia . I saw was 5.5 inches and they progressively get larger to about 20 or 24 inches or so, trouble is they come in 6 to 8 foot long pieces --enough to make coils for everyone in the neighbor hood. Anyway I'll grab some of that 5.5 inch stuff and have a go at it as I think Mark is really on to something here. Keep up the good work Mark

Thanks for the confirmation , i will try to keep it up  :D

Humm , i don't know , i don't think those guys like me much , and me i think they are no fun , if you know the result before hand , why would you build and test anything.

But i do drop it there from time to time , but most of it is borrowed content from here .

But thanks for the invitation .

@MK1

So I got around to making a coil this weekend.  It is thrown together with salvaged wire. This is different because I'm using the biggo ferrite cores.  The secondary's (12 turns=6X2) are underneath the primaries because of other tests I have been working on with inductive coupling. I have hooked it up JT style and at one point was getting about 13v out of it.  Now I get 2.3 or 2.5vac.  Oh I forgot to mention that the only place I'm getting voltage is off the the same Primaries that the BC are connected to.  The LED will only light one way so if I turn it around and hook it up to the same wires it will not light.  It also humms like a typical JT.   Anyway I though I would share this...well...failure.

You really should try paper tube , this coil is something different the the regular transformer .

Keep the good work !

I lucked out and found a 3'' dia cardboard!  I will make one today!  Does yours ring like a JT?  Also do you think the 3'' dia is too small?  any suggestion on winding it?

@Mk1

I forgot to ask you but did you get your micro tpu up and running?  I have been looking to make one of these!

Yes , the micro is working , but it doesn't really have enough room for the secondary .

I get about 9 volts form the outside secondary on 4 1/2 turns , it lights 24 led in parallel easy , i have not tried filament on it yet.
 
I also tried one secondary on the inside i got 12 volts for 3 turns.

My next one will be on a bigger tube , they work better over all .

The diameter 3 inch is good .

I am still working on the micro , but would not recommend building it just yet .

It still need to be further tested , i will send the info a.s.a.p.
