I'm tellin' ya, if you are going to use epoxy, anyone would really benefit from studying the WestSystem web site. They have so much excellent guidance information there. I've read it and many of their how-to manuals over and over and each time I still pick up something new. From the WestSystem web site - www.westsystem.com : Two-step bonding 1. Wet-out bonding surfaces-Apply a neat resin/hardener mixture (without fillers) to the surfaces to be joined (Figure 9). Wet out small or tight areas with a disposable brush. Wet out larger areas with a foam roller or by spreading the resin/hardener mixture evenly over the surface with a plastic spreader. You may proceed with step two immediately or any time before the wet-out coat reaches the final cure stage. 2. Apply thickened epoxy to one bonding surface. Modify the resin/hardener mixture by stirring in the appropriate filler until it becomes thick enough to bridge any gaps between the mating surfaces and to prevent "resin-starved" joints. Apply enough of the mixture to one of the surfaces, so that a small amount will squeeze out when the surfaces are joined together with a force equivalent to a firm hand grip (Figure 10). Thickened epoxy can be applied immediately over the wet-out surface or any time before the wet-out reaches its final cure. For most small bonding operations, add the filler to the resin/hardener mixture remaining in the batch that was used for the wet-out. Mix enough resin/hardener for both steps. Add the filler quickly after the surface is wet out and allow for a shorter working life of the mixture. 3. Clamp components. Attach clamps as necessary to hold the components in place. Use just enough clamping pressure to squeeze a small amount of the epoxy mixture from the joint, indicating that the epoxy is making good contact with both mating surfaces (Figure 11). Avoid using too much clamping pressure, which can squeeze all of the epoxy mixture out of the joint. 4. Remove or shape excess adhesive that squeezes out of the joint as soon as the joint is secured with clamps. A wooden mixing stick with one end sanded to a chisel edge is an ideal tool for removing the excess (Figure 12). ----- Original Message ----- From: "gordon stelter" <lclgcnp@yahoo.com> To: "Pianotech" <pianotech@ptg.org> Sent: Saturday, October 30, 2004 1:30 PM Subject: Two-step-wet-out ?????? > Terry, > Please describe this method. > Thanks! > Gordon > > > > > > > __________________________________ > Do you Yahoo!? > Yahoo!
