""""I've been thinking about mixing some powdered aluminum into the epoxy for effect! What do you think about that? """""

I think that will be a mistake ,if you mixing powdered aluminum into the epoxy for MOULD will be good ,will be much strong ,I mixjng for my mould, epoxi and quartz sand for more big bulk and solidity.I can use diamond powder or graphite powder but only for MOULD ! when I make the fuse from mould for first layer I can use only clean epoxi gel or epoxi gel with some colour and thixotropie powder ,I can make and other thing - I can paint the surface of mould with acril colour sray ,then I'll put the first lear epoxi ,and then I'll put the first lear of glass
I hope you understand my English.......

No problems with your english Rumen, it's very good. After some thought I think it may make trimming a little difficult. Too bad really, because I'm sure that it would look very cool. Oh well, I will just use primer, and then paint it later. Maybe I will try that experiment with an older mould set some other time.

I mix colour with the first lear of epoxi ,I use white colour in the epoxi gel ,but you can use metalik colour for epoxi resine ,the resolt is the best

You bet Buddy! I need to make one so that I can cut it up to get former cross sections. I've been thinking about mixing some powdered aluminum into the epoxy for effect! What do you think about that?


It will just turn it black.

...just some quick pics today
All looks good so far - I've just finished joining the two main fuselage sections here and I'm about to join and attach the tail sections.
This part will validate the tool function and provide a sample part for sectioning. The sections will provide templates for formers, radio tray etc..
I removed the bottom mould sections freely by hand to provide access for the joining operation. I used 3 coats of 100% carnauba wax as a parting medium. Detail transfer looks good, and as you can see there was very little flash. To colour the epoxy I used very cheap metallic flake acrylic paint. I expect to have a complete fuselage shell by mid week. I had a few minutes to post some pics and thought I would take the opportunity. Stay tuned - more to come.

I just finished pulling the first fuselage for the P-40 project. There will be another video very shortly to answer some more questions for you "how-to" types.
As you can see, there is still some flash to trim up, but the functionality of the tool has been validated. I also tried a few different experiments with seam joining and layup technique, so if you look closely you will see some variations. All in all, it will serve the pupose and I can fly my plane without fear of pushing the envelope. The weight is 1.6lbs or 0.73kg. It's probably a little on the heavy side, because I wasn't too concerned at this point.

Looks good. Personally, I avoid priming the in the mold, can't see through the fuse.

Please, tell us, what weight glass/type and how many layers did you use.
Again, looks good................ Now get a composite wing going!!!

Hey thanks Steve. That's not primer. After some research and a couple of trials, I mixed cheap acrylic paint with the epoxy at 10% of epoxy weight before hardener. I used two layers of 7oz standard biaxial weave cloth and I can't get over how strong it is. I'm gonna start the wing soon, but I've got a couple of guys who want fuses first.

The final video in the fuselage mould how-to video series (#9) can now be found on my youtube channel on this page here www.youtube.com/b1heqh54
Good luck with your own projects! It's been a blast.

Impressive work.

I forgot one of the questions I normally ask first. What does it weigh as pictured.

Refreshing to see custom hand made quality composite models by a skilled individual and not a production arf where the factory leaves nothing to individualize your model.

Thanks Steve - coming from someone with direct experience I appreciate the kind words!
Everything that went into the mould came out to just about 1.5lbs but my digital scale only goes to 200g at a time, so I need to get another scale to be sure. I think it's probably a little on the heavy side, because I didn't want pinholes. But man - it's strong! Yours seem to be a similar size - is that close to where you come in at?

That really does look great! What a complex mold!
