Default RE: BVM T-33 Build

Well, progress is being made. I now have the wings glassed with ¾ ounce cloth, and ZPoxy finishing resin. Because of the live hinge, you have to make sure that the resin does not fill the groove during the process. I have seen a few threads on alternate ways to ensure that the resin does not get in, but I used the BVM method as described in the manual, and it could not be simpler or more effective. They recommend putting a cotton string in the slot before applying the glass, and then pulling it out once the resin was applied. I thought that I should do a dry run before trying this process, and this turned out to be a good thing. The string must be much smaller than the groove, or the friction would be too strong to be able to pull it out. My cotton string had 3 strands, so I pulled 2 out and just used the 1 small one. I also found that it was much easier to pull from the tip. The process worked perfectly, and there was no tendency to pull the glass cloth out of place. As you can see, after one coat of resin, the live hinge is perfectly void of resin. I also found that by tacking a small piece of balsa on the opposite side, it held the aileron in position while glassing. This was easily removed after the resin dried.
