It would be interesting on how a large spiral wound DD goes up a against a large spiral wound Concentric and for a fair comparison be the same overall diameter?

Hi Mylab,

Yep, that's in the works too.
One version at same diameter as inner RX, another version at TX size or outer shell size.
Any other ideas let me know and I'll put that on the todo list...

No template just function in the applications
I use SolidWorks or Fusion360 depending on the job I'm asked to do. Both have similar tools. They have  helicoil or spiral functions and you set the diameter, pitch and height plus the material size or diameter. Then number of turns.
Other CAD software probably has a similar function but these are the two I use regularly.
Fusion360 is an online use application with a student version or hobby version available still I think for free. You will need 64bit Windows PC but check it out, its ok.
