I have used the heat tapes for about 4yrs. now.
I think they are the only way to go if you plan to build alot of bows. You can leave your form on the bench and cure a bow in a couple hours,vs. 5-6hrs. No more lifting a heavy form into a heat box. It is not for everyone,cost is around $300 vs. $25-50 for a heat box which you will need also.(for drying wood and overlays and such). Any specific questions please ask, I will help if I can.
