Now, that is what I am talking about. OK, I'll do it. Thanks for the info! Daniel On 2/22/2011 12:13 PM, W David Scobie wrote:

fill ALL the holes. this is a preventative measure against future leaks. only adds a few minutes of work as you have the hardware off.
i filled the handrail holes on SWEET PEA and then refiled with the first hole, second hole etc. and then redid the sequence a third time. i then mixed in the thickener and filled the holes.

I have it. It is available free online. It is just the logistics of never having done it. They tell you to "wet out" the holes first, which means squirt in the 105/205 epoxy without additives, and then later to fill with 105/205 and some additive such as 405 colloidal silica. My question is not about that process exactly, but the timing. I'm sure it will make more sense when I actually do it. The point is I don't want to fill the holes up to the top without leaving room for the second application with the thicker stuff.

Hi Daniel,
From your questions I assume that you don't have a WEST Repair Manual. WEST will gladly send you their Epoxy repair manual for free to help you do good work.
It's an absolute necessity that then answers all your questions of "How do I..."
Get one today!
Then enjoy doing the work.

So, my plan, is to take off the hardware and inspect the holes. Then I will use the bent nail drill bit technique to remove some core as needed, and vacuum out. Then I will tape the holes from behind with duct tape, and inject using a syringe West Systems 105 epoxy with hardener and fill the holes. I understand that I have to squirt it in a few times, as the balsa absorbs quite a bit. Any idea of the timing of that? Do I squirt, wait a few minutes and squirt again? Or do I squirt, wait a few hours and mix a new batch? Once done, I'm supposed to then mix a fresh batch with the colloidal silica as paste and inject for a final fill. Does this seem like a good plan?
Then, when cured in a day or two I will redrill the holes, and use 3M 4200 to bed the fittings.
Still just a little confused about the timing of the epoxy.
Daniel
