    One of this winter's Builds for the NAMBA DIST. 8 2120 Season

    Fabed up the build fixture out of 3/4 MDF I really like the stability of this material the fixture is perfectly Square and flat. Tnx to Scott Meyers of M5 performance for the hint on using this material. Ive started fitting The ML Boatworks hull parts

    Here is a really good Video on building a boat building Fixture

    I have to add 1 more piece of MDF to add to bottom of the fixture after I confirm that the tunnel width an break in the bottom are correct Don't want to tear it all apart if these are not correct

    With all the fitting and tweaking of the sponson side plates and rib's done.
    Finally started the glue up of the starboard side sponson side-plate as soon as the epoxy set's up. I'll start on the Port side then on to the engine rails.

    Learned a long time ago not to do too much at one time in case something shift''s epoxy is not very forgiving to disassemble if something go wrong. This is one time when patients is necessary and trust me I have NONE

    I ended up adding material to the framework edges to increase the gluing surfaces. I don't like gluing sheeting to 1/16" framework. Personally, I found this a very challenging build. But, my '85 BOAT runs fine.

    TNX Dunny I have always done the same thing with balsa 3/16 & 1/4 Sq. stick's to increase the glue surface and it really does not add that much weight but the seams and areas under stress loads don't fall apart

    I know you are still a long ways from sheeting the bottom of the sponsons, but I found out the sponson Angle of Attack was dang near zero with my strut depth at 1 1/4" to bottom of the strut. I increased the AOA by adding a 1/8" deep piece of plywood to the back of the sponson and using 1/16" plywood to create a wedge.

    stringers to make but this is enough for today.
