Richard,
I used the same method on the top blocks, andthe bottom blocks front to rear, including the portion of the bottom aft of the wing which is planked.
It's good to hear that you have members in your club who have been bitten by the Simla bug. Hopefully you will all share in the building and flying experience. As of yet I have found no one in either of the two clubs I am associated with who seems to share might interest and enthusiasm in the Simla. I guess I will just have to get her finished and take her to the flying fields. I would be willing to bet that some interest in the Simla would then be generated.
And yes, I have heard it both ways with sheep and cows.
