plane that I made. It was delicate and I was never sure how to make it stronger. I repaired it several times until the damage was too extensive and was thrown out. The second is the whole shaping the part until it looks good. I like straight lines. I am not the shaping type of wood worker. However I had a friend ask me to make a plane for her grandson and I am not one to shy away from a design challenge. The first ting I did was look at pictures and found a twin prop that I liked. There was some big unknowns with this project and a lot of them worked out easier than expected but not easily explained. First is that I wanted angled wings. Was not sure how to do this until I realized I could taper the bottom of the plane and the groove would follow the angle on the table saw.
The landing gear was the part that always broke on the first plane, so I took the easy solution and took it off. The tail section was the last challenge. I wanted sturdy and doweled. So I grooved the horizontal piece to accept the vertical piece. Before I glued the vertical piece in, I drilled holes in the groove through the fuselage. Then installed the vertical tail, drilled into the tail and installed dowels.
The propellers and engines were more of a challenge to cut than to design them. I will be reinforcing them with pin nails just to be sure they will not fall off. Glue usually holds very well but not during crash landings.
There are a couple of features of this design that I am proud of. The first is that it is a solid design. I want to see how my kids handle it. I am pretty sure they will do their worst. Besides the tapered wings the other design element that I though was clever was the thickness of the fuselage. It is 1 7/8" thick. This is two pieces of standard 3/4" material and a piece of 3/8" thick material. The tail pieces are 3/8" thick. The stripe that runs through the plane was planned and designed in.
This is one of the projects were I enjoyed the design process more than the build. This just was fun to figure out the problems. I really didn't know if it was all going to come together the way I had planned in my head. I am not sure if these plans will go up for sale. They need a lot of refinement and I will need to add images to the directions. It is too hard to explain the procedure.
This plane is made out of maple and walnut. I still do not like the shape until it looks good but a plane with sharp angles looks even worse. I will have to say that planes are a little less scary to design now.
