I don't really have the tools for that and im not so experienced with building planes and all that, the mustang was the first plane i built and before that i got the 3d printer so i had lots of ideas with what i could use it for.
I dont even have much space, i built my plane on the floor and my small table lol
If you have razor knife and a steel rule you have the tools. 1/8" plywood or thinner can be cut with repeated strokes of a razor knife. When combined with a steel rule to keep the cuts straight, it's as precise as a laser cutter, a lot cheaper and doesn't stink of burnt wood.
Lots of light cuts are your friend. Don't try to cut through all at once. Lay the steel rule on the wood on the cut line and run the razor along the edge of the rule. Start off just scratching the wood. Once you get a nice straight scratch established, do it again with a bit more pressure. Repeat until you're through the wood.
A few credit card sized pieces of sandpaper are all that you need to finish the piece. If you need a thicker piece of wood, cut out 2 pieces and glue them together with wood glue to double the thickness. Repeat as needed.
You can use this technique on plywood, popsicle sticks, tongue depressors, craft sticks, etc. If you're using short pieces of wood, you can glue them up into laminated beams to make longer ones. Just make a 2-layer (or more) piece where each layer acts as the backing for the other layer's butt joints.
Finally, don't forget that i-beams and u-channels will give you a lot of stiffness without a lot of material. Look at the standard Flitetest u-channel foam wing spar. That same shape laminated from tongue depressors will be much stronger and only require straight cuts with a razor.
. I want to build another one and modify it a bit so I was thinking if it could be possible to 3d print a wing spar that connects the 2 wings together. I was wondering if anyone had done this and would this affect performance much?
