Subject: Photo's of keel tube install on cedar hull
Dave, I am attaching 4 photo's showing the radio tray , keel tubes glued in , how I made the keel tubes , and the keel tubes installed .
I used brass tubes on this hull and found that they were very easy to align due to the snug fit in the drilled holes. Since this fin had the standard bolts on it I put a shoulder on the inside by soldering together a couple of different sized tubes. Photo shows one already soldered and the other before soldering. I will then take an aluminum rod and thread the end to hold the keel.
I then glued the tubes in the hull using JB weld since it has very good strength for bonding metal. That is the silver colored epoxy. Time will tell if it was a good choice.
The radio tray was simply two 1/8" X 3/8" spruce strips glued in. I also added a vertical reinforcing PC in the middle. All the joints were strengthened with a small PC of fiberglass that was held in place by 3M77 while gluing. I add the glass to make sure the joints never come apart. On one boat I had to cut the radio tray out when I moved it since the glassed glue joint was so strong.
This boat will have a deck mounted winch like the first 3 that I built.
