It was originally 50ft tubing and I've added another 10ft. I really need to redo it by using a 60ft (longest they sale that I've ever seen sold). And then I can add to that. If its going to be more than say 80ft of tubing needed, then a major redesign is in order. I was only considering it if it can be used with my current coil without major redsign ie redoing the coil supports hold that much tubing.

John,
My earlier reply 'assumes' you have sufficient spare turns on the primary to
play with, otherwise as Gary points out you'll need to add some outer turns.
Either way, watch the coupling.

You need to be careful with the 'k' or coupling factor. A larger secondary
will be nearer the inner turn of the primary and you may end up over coupled
causing racing sparks. Also the reduced clearance to the inner turn may
cause flashover, personally I would remove the inner turn ( one whole turn)
- it will have little effect on the primary inductance.
Use Javatc as a guide to get the right coupling or 'k' factor.
The 0.25 inch tube will be ok as there's no need to change that unless you
increase power significantly.

If I just swap my 4" x22" secondary with a 6" x34"secondary and bigger
toroid 6" dryer duct vs 4" are any other changes needed other than retuning
the primary? For instance instead of 1/4 tubing primary would the diameter
have to be increased? I wouldnt be changing anything on the primary side.
It would just run weaker until I increased the nst current and mmc array
right?
