Agentgates´s TPU setup with strange wavehill hump

[PARAV]

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

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 .
