Christmas time inspired me to get back to the long-abandoned building board for some more dust-time!
Sheeting the hull ahead of the step
A rather uncomplicated matter given the simple shape but... things got though approaching the nose. Rememeber I couldn't bend those very soft 5x5 balsa sticks?
I wanted to run one(*) balsa sheet from the step to the nose but I couldn't. Bending the grain was really too much -close to the nose-. I decided to end the parallel-grain sheeting up to bulkhead C20 and continue with cross-grain from there on.
I added some scrap balsa (red arrows) around the bulkhead where they'd meet (green line) to provide better support and anchoring.
After-thought: a better (and too late) way to sheet it is to end the parallel-grain up to a point where a single cross-grain sheet would be required. Bending is indeed critical but only -really- close to the nose. Hull will be fiberglassed so it isn't really a structural matter... Additional support (scrap balsa) is advised anyway.
Sheeted with Gorilla Glue, applying pressure with the custom-bar sander and masking tape. Remember GG foams... make sure things stay where they belong...
(*) Hull width requires you to join balsa sheets to cover it in one piece. I prefer to do it prior to sheet for a better surface at the joint.
ORIGINAL: g_boxwood After-thought: a better (and too late) way to sheet it is to end the parallel-grain up to a point where a single cross-grain sheet would be required.
Just added a pic to clarify a bit what I mean (lower pattern). Or at least this is what I hope... Dotted lines denote joined sheets.
I need advise on splash rails: are they needed? I saw a few model designs feature them.
Do they: - improve water handling? - prevent water from hitting the props? - help get onto the plane quicker?
and in this useful post that stresses how every kind of gluing job needs a -specialized- adhesive (IOW you can't use GG instead of -every- other adhesive):
Happy new Year to everyone! I know I'm late but I've been away... from town and ADSL...
Although I was away from my workshop I did my homework and CAD modeled the MAIN GEAR: I basically drew again all the components already drawn by Bernard just to get a better understanding of the involved cynematics. Again, everything is very well thought-out and the gear looks incredibly scale as well (check out previous Strykaas pic)!
I first modeled the gear in Rhinoceros and here are the resulting renderings.
