Building Seamaster Day 64: Hatch & Water Rudder

Silicone Trimmed

On June 17th, you can see where the silicone after drying was cleaned up around the wing ‘craddle’ in the fuselage in the featured image above.

In the image below you can see where the hatch, covered in yellow to match the top of color scheme of the aircraft, was screwed into place. This allows access to the nose where weights have been installed, if necessary.

I also installed the water rudder. This allows for better steering of the aircraft when taxing in the water. In the left image below you can see the ‘stopper’, screw with a piece of fuel line tubing covering, sticking out. This prevents the rudder, when in flight, from getting stuck in the up position or in a spot that would prevent the planes rudder from functioning properly. That way, once you get back in the water the water rudder will drop back down allowing you to steer while taxing again.

I cut the ‘water rudder’ out of a piece of metal after tracing a template using the table jigsaw and then using a metal filer to file off all the burs / rough edges providing a smoother finish. Want to make sure it can cut the covering, me, etc.

Wow, I’m now all caught up on my Seamaster Build posts! I’m not calling this build done yet, and has been a two year process as got started late on this one (Feb. 10, 2018) so perhaps 1.5 building seasons. 🙂

I will have to check into what all is left to do, beyond starting it up and seeing how everything moves along with the maiden voyage. Not sure where (or when) that is going to happen!

Building Seamaster Day 63: Silicone

Silicone for Water proofing

June 15th was about water-proofing the cradle in the fuselage for the wing. This involved using a cocking gun to apply silicone all along the top edge of the cradle in the fuselage (where the wing sits) and making sure to place lots up under the ‘water-deflector‘.

To prep for this job I wrapped some seran around the front center of the wing and taped it in place to prevent silicone from getting onto (and drying) to the covering of the wing. Teh wing is assembled on the fuselage during the drying process to make sure that the silicone forms properly to how the wing needs to fit and a tight seal is made.

Unfortunately during this process (we didn’t test the wing installment first as hasn’t been tested since installing the ‘water-deflector’) we realized the wing didn’t fit on the fuselage anymore and had to use the dremel tool to shorten the backside of the deflector, which will have to be covered again (since wood on the back edge is now exposed) , to get everything to fit correctly.

You can now really see the aircraft coming together in the image below:

Below you can see what it looks like from underneath. The seran taped into place and the wing sitting in the siliconed craddle.
