Aftershock, composite glider...
I am working on making a composite glider that dale had designed many years back, as we both got out of the hobby it was shelved. Am back to flying and want to make my own planes, so I am getting busy with my cnc machine and putting this together.
This is the concept:
To start I need a fuse plug, so I cut it out of MDF, in halves, then glued it up and soaked it with epoxy to harden the surface. Some sanding and filling has started. But I will need a wing, horizontal and the vertical tail pieces, and canopy made, in order to fit to the fuse plug to make sure it is sanded properly to shape.
The vertical piece get's the same treatment, here one marked, one sanded.
Then loads of sanding down to 3000 grit and polishing, need to get them as smooth and shiney as possible so the molds I make from them are good. Getting there....
Should be able to get started cutting wing molds in corian tomorrow. 3d models of cuts below.
For alignment in all the parts, I drilled in with .25 bn mill, will use .25 ball bearings, set in on one side, and out on the other. That will be for all molds I make.
Wings will just have them glued in on one side since that is mold instead of plug.
For the next one, which will be the other side of the mold, think I am gonna try to pour paraffin wax in the trough instead of clay, less cleanup I think. Also do a little better with the clay around the edges of the damn.
