Henry,

This has been on the web for maybe 10 years, and may well have been 
Dave's original inspiration:

I wouldn't get all excited about Litz wire.  Like I said, the feedback 
is going to take care of the Q.  Start with what you can lay your hands 
on.  You'll want something fairly thin.  Plastic insulated wire is 
preferable to enameled wire.  Be emotionally prepared to change the 
number of turns on the secondary to cover the desired frequency range 
after you get the set working.

PVC pipe is preferable to a cardboard tube.  Common inch-and-a-half 
schedule 40 is almost 2" O.D. - close enough for government work.

I don't think the RF choke is really necessary in this circuit.

I also wouldn't get excited about Q-dope.  If you wind the coil with 
reasonable tension, it will stay put.
Here's my suggested winding method:

Also suggest you breadboard the set before you do a lot of careful 
drilling and blasting.

Have fun,
Al
