There are three people who are waiting to get one of these planes instead of the 80" planes. Im upgrading their order in exchange for the extra wait time. I need to take care of these guys before I can take any more orders.

I look forward to seeing the results. I have been studying up on hollow moulding, and this thread will surely be educational!

Nice Joe. What modeling software are you using? You seem to have access to some sofisticated equipment. That has to be a big help in getting a project like this off the ground.

Paul. Who's probably going to get red faced on this one
Sorry it took so long to get to this one Paul. There are other tooling materials out there but frm what I have heard they arent worth the extra money. MDF is easy to sand and fill and that goe a long way when you need to clean up witness lines or other small imperfections. It is also thousands of dollars less expensive to use MDF than it is to have aluminum female molds made. Im actually considering having some made but there is a lot of hand work (labor) to clean up aluminum after it is milled. That alone jacks the price way up.

The guy doing my milling is experimenting with resins. We will see how that goes. Sorry I dont have more info on other tooling boards but It was reccomended to me that I stay away from it because it's not worth it.

I saw on another thread where the guy milled the MDF past the surface that he wanted. He then coated the MDF with epoxy and then final milled the epoxy surface.
Just a thought.

What about utilizing a solid surface material similar to corian or thereabouts?

Wouldn't that be a little more stable, still millable, sandable, patchable?

Sorry, I just fell into the thread. Looks like an amazing project. Keep up the fine work Joe!

if you haven't upgraded to rhino4, do it.. It makes previously difficult things a whole lot easier (variable radius fillets.. yay!)

Freak, Corian seems like it would be ideal. Ill look into it!

Oz, I barely know enough to look at images on Rhino. The CNC guy is doing all of the cad drawings from my specs and ideas.

I've seen wing molds made from corian.. beautiful! But.. a lot of hand finishing work required, and the stuff is apparently hard on tools, even carbides. Another alternative (down here in Oz anyway) is caesar stone, but again, not the nicest material in the world to cut. The dust made when cutting this stuff is similiar to cutting cement with a radial saw, and gets everywhere.....

I got my fuse plugs. I sprayed a couple coats of black varnish on them and let dry.

Once dry (24hrs) I sanded them with 220 grit. There is a 2" long cap that plugs into the back of this fuse not shown. I havent got it yet. It sits under the elevator control surface. It allows access for seaming the fuses up in the mold and is access to the elevator servo which will sit under the elevator.
