Do you have any pictures of the bid tape. And a part number . Sorry I can
not picture what you are using.
I would love to not have to cut bid tapes

I'm now using West exclusively. I use the fast hardener and mix it in small
batches. Layups gel within an hour. If I hit it with a heat gun after it has
gelled (and the exotherm danger has passed) it is fully set and sandable
within a few hours. It keeps me building instead of waiting. I switch to the
slow hardener for larger batches or projects that I don't expect to work on
again in the next for 24 hours.

 

While we're talking about West products, their 4-inch 45-degree BID tape
saves a ton of time cutting tape strips! It's 50% heavier than the 8.9 ounce
BID that the kit calls for and its fibers are not woven ( they're held in
place with a non-structural thread, like triax), so they are supposedly even
stronger than woven BID. Anyone else using this?

I got a lot of different answers to my question about epoxy from everyone.
They were much appreciated. Today I called Velocity and asked them. They
told me that I used the wrong hardener, which you all told me. They said
that I could use the West as long as I used the slower hardener. In my case
it is the 206. He did say that the 209 would be better but if I mixed more
micros, they would take away some of the heat. He also suggested that
instead of trying to fill the entire void which was created, that I epoxy in
close cell foam to fill the original area. He told me to let it dry using
the 206 and the next day I can cut a slot just a bit larger the the horn and
epoxy it into place. The last thing he suggested was to put one layer of bid
over the repaired area, sand , and paint. 

 

So today I followed his instructions and had no problem. Tomorrow I will cut
my slot and epoxy in the control horn. So not others know the "right" way to
do this repair. Thanks again for all of your comments. It helped a lot.
