Have you done the experiment??? .. Obviously you have.. You have been at this for years and I'm sure you wouldn't be just making all of this up.. Did you record it.??
I didn't, but no point really as I didn't achieve anything.
Please post the successful experiment on youtube.
I will try to replicate it..
And the details .. Method..Tube diameter.. Wall thickness.. RPM.. Drilling Pressure..
And anything else that you think may be useful in order to replicate it.
If successful I'll post an unedited video on youtube along with yours.
