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!
