Fiberglassing

Submitted by aaron.axvig on Wed, 12/12/2018 - 03:00

First fiberglass job today. This is just a thin piece of about two layers of chopped strand mat and poly (instead of stronger and more expensive epoxy). It will be glued onto the back of the dashboard where some old instruments were cut out, and then we can fill the old holes in against that backing and drill holes for the new instruments.

Two pieces glued in using 5-minute epoxy. 5 minutes is a long time when you are contorted to hold the pieces there until it sets.

More project

Submitted by aaron.axvig on Thu, 12/06/2018 - 03:00

Progress today:

Put fiberglass panel back on the cabin roof, had to be careful to seal some screw holes to be watertight.

Installed new navigation table light. The old one didn't work, this one can be either red (to preserve night vision) or white and dims. The kit I ordered was not great so I rewired some of it and put a different switch on it.

Installed new VHF radio at nav table. There is one at the binnacle but it doesn't seem to work. I suspect the antenna on the top of the mast is gone as I can't see it from the ground. It will be good to have access to the VHF from inside, and the binnacle will get a remote microphone so will still have access there.

Wired in the charger for the handheld VHF radio. Now we don't have to plug in a wall-wart to supply 12V to it, it is wired directly into a 12V circuit.

Wiring things in

Submitted by aaron.axvig on Wed, 12/05/2018 - 03:00

After a couple days of part-time poking and exploring where existing instrument wires go between working on other projects, today I got serious about getting some wiring done. Almost all of the floor boards were taken out at one point and there was some delicate wire fishing. But here is the first indication that I am on the right track with the new NMEA 2000 instrument network. That little 4" display shows changing numbers when I spin the paddlewheel sensor with my finger (normally would be spun by water).

Next up is to extend the network to the cockpit where it will provide the same data to the chartplotter and 2-3 4" displays.

Another big hurdle will be to get an instrument installed on top of the mast and then connected in, which will probably be in a week or two.

Removing old transducers

Submitted by aaron.axvig on Sun, 12/02/2018 - 03:00

I removed the two old transducers. One was for sending speed and the other for depth. The nut on each was size 2 1/2" so I needed a huge wrench. The remaining hole is a bit bigger than it needs to be for the new transducers so I will need to research whether that can be safely filled with sealer or should be filled with fiberglass and then drilled at the proper size.
