Hank, thanks for the advice...I was pondering that very thing. I may have to go ahead and do that. It wouldn't take much.
Jay and Ebag4, I will have to look into that glue. Thanks.
While I'm at it I have a question for you guys. Maybe this should go on a build thread... anyway, I have everything cut. A good friend of mine has a pretty sweet shop and he let me use his table saw, so I went ahead and cut all of the pieces. Last night I made a circle jig that seems to work well. Practicing on some scrap 3/4" ply my first hole was too big (5"), the 2nd too small (4 3/4"), the 3rd was just under a 1/16th too large. Well, the GR package came today so I sat down to open my late summer Christmas package that I paid for and grabbed one of the drivers to check the holes. There was quite a bit of play with the 3rd hole (gasket still over the edges) so I set it in the 2nd (4 3/4") and it looks like it fits much better. There is still some wiggle room but not much. How snug are these holes supposed to be? I was going to put a 4th hole in my jig (figured I could finally get that 4 7/8" hole that the plans called for), but is that necessary? Thanks for any tips. Also, if you think I should start a build thread and ask the question there let me know. I'm not terribly familiar with forum etiquette!
Thanks again! Everyone's suggestions have been very helpful.
Todd
