Hello Dennis:
    I would suggest that you would want to obtain an acrylic tube with a 
1/8" wall thickness in order to make winding the secondary a "reasonable" 
task.  I recently spent alot of time reading through the catalogs of 
three different industrial plastics suppliers and I did not notice any 
tube with a .010" thick wall.  Since acrylic is really a fragile material 
I wouldn't expect to find anything with a .010" thick wall.  Several 
coilers have used forms with 4"-10" diameters with about 1/8" walls I 
believe with good results.  If you check your local yellow pages you will 
probably find several plastic supply houses.  Midland Plastics in 
Milwaukee, WI has a retail desk and takes charge cards too, if you can't 
find something closer to you.  Phone is 1-414-783-3460.  Good Luck!
