Hi Mr. Barnacle very kind of you, both the offer and the interest.
The keel is 5" wide at max. so at 2" the DF would not quite get there I think but sounds like you have some great spar making material or anything else for that matter. I'll certainly look forward to the dimensions I've still to decide on some stuff for the inwhales not sure if my stash of celery top is going to stretch that far.
I got brave tonight and used the electric plane to take the garboards down to the inner keel. Even though I'm ready to hang the second planks seems I'll find anything to do to avoid mixing that darn epoxy. :rolleyes::D
