And I'm not so sure my glue Fu is powerful enough, or dynamic enough for this caper.
It takes a lot of plane work and file work to get to anything that looks by eye to be about right.
The big problem, that is the problem bigger than the ones I'm dealing with now, is that I have to go on to make another of these on the other side. I have no idea if I can do that.
This blade will work, but its a thing made by eye, and it's a thing that deviates from the image I have in my head. Its not the same as the image in my head, how am I going to make another one that's the same as the one I already made.
I used PVA wood glue. (that white stuff you can make removable fingerprints with when you should have been listening to your teacher) But I think some epoxy might have been a better bet.
It should be safe enough because all sections will have the shaft through their centre, so if it all comes unstuck it will just be a motley collection of different shaped puzzle pieces spinning around in the breeze.
I'm really not sure if I can make another blade the same as this without developing some other method. I have a pretty good eye for 3D shapes as a result of doing a bit of pottery, but I also have a pretty good understanding of the limitations of my current skill set.
At the moment I'm thinking...
- Cutting this blade up into sections so I can trace the shape onto thin sheet plastic or something so I can cut out a series of section profiles that I can test a new blade against.
- Mould making to duplicate this blade in cast plastic or something.
- PVC (with PVC, I could use a template so I could copy the first blade I made. Other people have used PVC with some success, especially on smaller windmills like this one.
- Or even making a big version of my proposed lure copying machine. I'm pretty sure that would work, and it only requires longer threaded rod to make the thing big enough for this project. Longer threaded rods, and being built in the first place.
- Something else
Mould making was suspended until I had a project that actually required it, so perhaps this might be it.
But I do love working with PVC. It's just so easy to cut, file and drill. Mmm Polyvinyl chloride.
