Heat n Bond Tape Issues
- View Source
I had problems with the Heat n Bond when I first started. If I heated it every 3 inches it wouldn't separate from the roll. The only way I could figure out how to separate it from the cover was to heated it the full length, with the result that when I went to use it it wasn't effective. You really need to just spot heat it every 3" like they instruct you to, and work at separating it. I ended up building an extra (outwale) to sandwich the kevlar and dacron, epoxied and screwed it down and "that stuff sure ain't going anywhere now!" My method works, but it added needless weight to the boat. When in doubt, follow the instructions!

A lot of people are but off on the application of dacron and of heat srinking the fabric.any suggestions to ally their fears.

I don't know about the Sweet-Pea plans, per se...but I did build the ARROW14. That plan set calls for "Heat n Bond" tape at the gunwales as well. The tape is pretty amazing stuff, if it is applied correctly to the gunwale with the hot iron, as Platt suggested in his plans.
At least on the ARROW14, an additional wooden rub-rail is fasted over top of the Dacron/gunwale, with wood screws every second rib, to "pinch" the Dacron tight between two layers of wood.
One other thing..."Heat- n-Bond" tape is also sold at JOANNE FABRICS stores...many a retail mall contains this store...they supply several heat ranges and sizes ( I found the exact stuff that came in the ARROW14 kit at one of the stores). Many a seamstress will use the Heat_n_Bond tape to permanently bond a garment or clothing hem. That store might be the place to pick up an experimental supply (it's about $3-bucks) to "calm your fears." As I said, the tape is amazing stuff, very strong in shear...not so strong in "peel tension."
Some of the photos in the albums might be of help to you...I recall that I posted several showing the taping at the gunwale.
hope it helps,

Subject: [Airolite_Boats] Kevlar adhesive question & List searchable archive?
I never built a boat before. Phew, got that off my chest. I took on
the Sweat-Pea MK2 project to do with my kids this winter. I've just
cracked the plans, watched the Monfort video and been watching this
list for a month.
I would like to know if anyone has problems with the Kevlar coming
loose after construction. I see in the plans and the Monfort video
that it is only held on at the gunwale with heatnbond with the Dacron
over it. My inexperienced head can't imagine that it could hold that
little surface area of the Kevlar very well. Wouldn't it just pull
right free or am I underestimating the adhesive power of this the
heatnbond? I don't want to experiment because I don't know if I have
extra in the bought materials kit.
Second question, is there an archive of this list that can be searched?

To answer the second question first: http://groups.yahoo.com/group/Airolite_Boats/messages There's some good stuff in there.
The first question: yes, the adhesion of the heat'n'bond is sufficient to hold the tension of the Kevlar. There really isn't that much tension, actually. The shrinking of the Dacron actually pulls the frame together a little, resulting in some slack in the Kevlar. So you then go back and re-tighten the Kevlar. That's why you DON'T trim the Kevlar until after you shrink the Dacron. The tension is distributed across all the strands and the Dacron.
It all just works. J
