For height/dia. ratio for coilform winding length use 4.5:1.

As an example, a 6.5 inch OD coilform would require a winding length of
29.25 inches.

Use 1,400 turns as a good value.

Dividing 29.25 winding length by 1,400 equals a wire dia. of .0209.  You
then look up this dia. in the ARRL Radio Amateur's Handbook (available at
any large library) and this will give you the proper wire guage to use for
your winding.

I always recommend using a 200 degree C. high temp wire as it has thicker
insulation and offers better protection against "dings" if you ever drop the
coil.

Seal the winding with 4 separate coats of Dolph's AC-43 (see their website).
Allows 24 hrs to elapse between each coat.  Keep in turning for 30 minutes
to prevent sags and runs.
