Avon Sabre Spirit 78

Thanks, Martin. I did wonder about leaving the last planks until after joining, but with the aim of smoothing over the join line. I'd forgotten about being able to clamp them, so thanks for the reminder. -

Part Planked One complete sheet of 1/8 x 3 x 48 has now been dissected into thin tapered strips and applied to the fuselage. The nose and tail now look like this: The tapered strips are working well, but I don't yet know if they'll be practical as the curvature tightens up. Tracing the way ahead I'm going to start the second fuselage half before completing this one, so that I can check that the two halves align accurately. Just visible in the photo above is a sheet of tracing paper underneath this half. I traced around the framework and then laid it upside down onto the second fuselage half on the plan to check that everything was going to line up. There are minor discrepancies, as expected, but I'll build onto the tracing to hope they match: I think the main aim is for the two halves of F4 and F7 to align accurately at the wing seat, where fellow F86'ers will be able to spot any mistakes! -

Thanks for the comments. Harry; Mark has posted a few videos of the CAC Avon Sabre, on his Sabre F86 thread, if you want to see more. Meanwhile.. Get planking I have never planked before, so this is a step into the unknown. Where to put the first strips?? I decided to put them straddling the central stringer. They don't follow the stringer route exactly as I allowed them to 'relax' into place without too much twisting and resultant in-built tension in the frame. I am trying to use tapered planks, approx 8mm in the middle, tapering to 5mm at the nose and 3mm at the tail. Whether this will work for all of them I don't know but it'll be exciting finding out: Accommodating the sharp tail curvature is going to be the biggest challenge, hence the narrow strips: -

Mark, Thanks for posting the CAC Sabre clips. Useful information for my CA-27 version which is essentially the same airframe.

Wing Bolt Plate Doing a dry fit of fuselage parts I noticed that WP1 as cut in the kit, and shown on the plan view, does not butt up flush against F7 when inserted into the slots in F14. I therefore cut 3/16" off each tab and epoxied the bits onto the front, to move the tabs forward and allow WP1 to sit back against F7. It now fits flush, and could be reinforced with triangle strip if necessary: I believe this is correct according to the fuselage side view of WP1: Side by Side I then ploughed on with assembling the first fuselage side. I chose to laminate the bottom keel from two pieces of 1/8 x 1/8 to create the curvature, and to align and glue the formers against this before adding the top keel: However, this resulted in a slight mis-alignment of the tops of the formers with the top keel, which is straight. I lengthened the slots in F9 and F10 to the same 6mm width as the keel, and managed to get it all to fit: The only small issue I had was trying to hold down the part-formers F3 and F5 and keep them vertical. I therefore fitted them at the same time as adding the stringers, and applied suitable weights onto the stringers (not shown). Now onto some planking..... -
