Good morning, all,
I have just a little more progress to show. I began setting the stern ribs to see how well their deep vee design was going to fit. I made sure the bottoms were seated all the way down into the keel/stern post but had no way of knowing if the tops of the ribs were actually sticking up the correct amount. I had heard from other builders that the stern ribs were problematic like the bow pieces were. So, I measured off of Ancre's plans which are identical to ZHL's but much cleaner the distance from bottom of keel to top of rib and sure enough my rib sections are anywhere from 4mm to 13mm taller than the plans. If they have to be off, I would rather be too long than short. I had been forewarned that the keel has a strong tendency to rise up off the floor bed as you glue down each rib and it certainly does with mine as well. Obviously, you cannot achieve accuracy on any aspect of the build with a keel out of alignment, so I focused this update on the hold down shims for future builders' consideration. First the stern ribs and height measurements off the plans.

Here are close ins of the keel hold downs. It's amazing but there is enough tension in the ribs against the jig that makes the keel want to rise vertically.

In the next photo I closed in on these little shelfs that stick out of every tenth rib. They proved support for certain bilge ceiling and clamp planks for interal support. Had I thought ahead I would have left them out until I faired the inside of the ribs, now they are just in my way. I may map the shelf and clamp strakes and just grind those little supports off???

Well for now that's my story and I'm sticking to it.
Thanks for checking in hope you all have a great weekend.
