    In another life, I'll add toy tabs in these locations to make it easier to build.

      Here's another shot of the front frame position with the stand-offs on the back. Maybe we could cut out a jig for this if there is extra room on the sheet? It could have a flat side and another side that has the angle of the AOA on the sponsons and could slide underneath the frame?

        I appreciate all these insights.

        When you say to sand the burn marks with no lower than 220 grit, do you mean all the slots or the slots and some of the part faces?

          Hi Ray,

          Only the faces, not the edges. It is typically only on the back face where the smoke from the laser is exhausted. Lately, I've been keeping all the parts in the sheet, laying the sheet onto a flat surface, then hitting it with a palm sander. That way I don't round off any of the edges. It makes the build a lot cleaner looking without all those nasty burn marks, otherwise, they will just be sealed in for life!

            O.k. that's a great idea. I thought the slots where the pieces fit together also need some sanding because of the burning?

              It seems epoxy would definitely adhere better to "non-burned" surfaces, but I've never had a problem not sanding the edges. The joints are heavily reinforced in later steps when the glass strips are layed in. The framing is mostly just to tack things together, although I've found frames to still be very strong with West Systems.

                Wow. Here I was in the past trying to clean the burn marks out of the slots, lol... I am learning a lot from you Pete.

                  I sand every slot. Not crystal clean or anything. Just some. When I seal I use thinned epoxy. My thinking is that it can soak in to the joint a bit in the process. I wipe every flat surface after my thinned mixture has cured a bit but those joints I let sponge.

                  The trick part about sanding slots is that you have to keep washing your hands. You will get soot on them and it will make the wood surfaces look horrible. If you want to eventually have a wood finish, wash yer hands constantly.

                    I have the V12 version and just a great hydro man. Have you made any new changes or improvements since the version 12.

                        Maybe you are learning how do things 'wrong' from me, Ray!

                        Terry, that is nuts, as usual. I think I asked what it eats last time.

                        Ryan, I love the green and white scheme.

                          I'm a little behind you Terry. Getting ready to install the bottom on the Q. Also, started the framework for the Q cowl. These boats are a labor of love, for sure.

                                Nice, looks angry.

                                Yeah, I notice that mess too. I am almost ready to get started. Something was off and it appears it was my square, bent. I just borrowed a proper one so now I can set up the build board and then pull parts to sand.

                                Since I cold not get a nice aluminum (long) sanding block I had to make some out of oak. Those Great Planes sanding blocks Pete shows are a thing of the past. Dubro has taken over and doesn't make the long one.
