RE: Brent Good Custom Airframes 50cc Yak 54
The first picture is a fixture that I use for beveling my hinge line stock. It is a peice of alum. angle screwed to wood blocks that have been cut at a 20 degree angle. I then set my bandsaw cutting deck to aroung 10 degrees. You can do the same thing with the rip fence and setting the table to around 30 degrees. I use the alum angle just because it is a little more convient to hold the stock to and I can lower the cutting guides a little closer to the peice that is being cut.
Make end caps for the stab, ele out of scrap 1/16" balsa and glue them on with tightbond. I use a stick ontop of the cap with tape holding it down while the glue dries. The stick in the middle applies even preasure the full length of the cap.
Cut 4 peices of 1/2" balsa plank 12 1/2" long. The 4 peices need to be ripped to the thickest measurement on the stab. It should be aroung 1 3/4" to 1 5/8" depending on if you have 3/32" or 1/6" sheeting. Tape 2 peices together. This will make the ele side and the stab side of the hinge line. Mark the center line. Now mark the hinge locations. I place the first hinges 1" in from each end of the hinge line. Then I add to more hinges devideing the space evenly between them. It will be aroung 3 1/2". Drill 3/16" holes for robarts pin type hinges. Mark the peices bev for the side that will get beveled and which side goes to the stab or ele. Mark the bevel you need to cut on one end of the peices to get beveled. Adjust the saw and fence to get the blade where you like it. I don't cut it to the exact size. I leave a little extra to be sanded off once the bevel is cut.
