Page two has the line drawing. Trisailor was nice enough to add the picture of it.

Amazing progress and fine craftswomanship Roberta. I cant think of any better way to deal with the cold and snow up there than to keep at it in your heated shop.

Thanks, Chris!! I am truly enjoying this build and get more excited and motivated as each milestone is reached.

Now, Roberta, you wouldn't happen to be shooting for a launch date sometime in the early summer, perhaps at a a large body of blue water in Utah?

All kidding aside, your progress is amazing. I love how fast this is coming together. I am interested in your fix for the too narrow frame. This is precisely why I have spent so much time trying to get my last frame positioned. I believe i have now.

Anyway, great work and looking forward to more progress.

Thanks, Carl!! I'll be posting pics about how I am correcting minor discontinuities very soon.

I spent Thursday and Friday cutting notches for the chines and getting set up to install them. Today Rich helped me clamp the chines in place and I marked and refined the angles in the frames. I use a block sized like the finished chines to check fit the notch. Once satisfied with the fit, the cut is made for the chine to stem fit. Clamping the chine to the stem gives a good idea for the angle needed, but this is usually not right as the chine is not really in the correct spot. A second cut is made with the chine in the correct location on the stem. Then all the screws are drilled and set to make sure everything is fitting correctly. Then the chine removed and re-installed with epoxy. Always make sure you leave a tail on the chine to ensure you have extra to make several cuts at the stem. The simple guage Glen L uses to find the proper set back of the chine is easy to make and use. This ensures that you will fair the stem into the chine properly.

Completed base chines. Two 3/8" lams will be applied to the base chines to build them out to 1 1/2".

Nice lines on that hull Roberta, looking good.

You posted this a couple post's ago.

Can you elaborate or point me in the right direction to see this gauge? As soon as Chine scarf joints cure, I am going to start that step.

Thanks!

• 
  Fig. 6 - After the stem is beveled, the chine must have its
  outer surface extend to the center of the stem. Since the
  chine is installed before the stem is beveled, a "checking block"
  such as shown above, is used to determine its position. It may
  be neccessary to fair the chine blocking depending on the
  thickness of lumber used for the chines.

Yup!! Just like Hotrod's pic. That tool is shown in the "Build it the Glen L Way" booklet included with the plans. Basically a straight edge with the notch as shown. If you laminate the chines, it is necessary to lay the full thickness of the laminations on the chine at the measuring point to get the correct setback for the first piece so subsequent pieces will end up at the correct finished setback.
