My first instructable, here we go! I always wanted to have a old wooden airplane propellor just for show. It's something every guy needs in his mancave. To bad the real thing is pretty costly so why not make my own? I got plans from a site (witch is in fact a walkthrough on making a propellor) and I went to work.
Note that I made my prop with 2 types of cheap pine wood. Making it out of oak or maple was to expansive. We got pines enough in Holland so I went with that.
Little disclaimer: This propellor is ment to be a decorative showpiece. Not a real propellor to use on a plane or something!
Step 1: Printing the Plans and Drawing Them on Wood
First I printed the different layers on normal A4 paper. I changed the measurements in Photoshop to get a ruff 1,5 meter long propellor. This was all done without a ruler a tapemeasure. I kinda eyeballed it. Then I traced them over on the wood. I used 2 different kinds of pine so it would look nice.
Step 2: Sawing and Gluing
Then I just sawed all the 8 pieces out with a jigsaw. Gluing them together was a pain but I managed by gluing them in sections. Note that you need to glue them in a spiral.
Step 3: Sanding, Sanding and a Litle Bit of Sanding...
Ok this is by far the longest part of the build. Right of the bad I noticed that with normal sanding this would take eons. So I tried 'sanding' with a anglegrinder. This worked pretty nice! When the rough shape was done I took a palmsander with grid 40, 80, 120, 180 and 220 to finish it off.
Step 4: Staining
The last step was staining. I just took a dark color i had lying arround and slapt it on. You could use polyurethane aswell. Since this project took long enough I didn't bother. Done!
