Started reviewing the plans for the Cabin Assembly. This is specific to the tip-up model and I spend about a hour reviewing the plans and measuring the outside edge distance on the fuselage. Plans v.s. actual fuselage width was about 1/16:" off vs plans. I did some minor grinding to the center channels to get the exact width and height. Clamped down the entire assemlby on my work table and drilled the joining plate and clecoed.
