Clear resin also "likes" heat treatment to get to its full specs on hardness.

That applies to most resins, especially polyurethanes. they tend to become much stronger with post curing treatment, but generally you don't need to for model use.

That's him! Thank you for finding his name!
Love that sub. Is Rick still around?

[redboat219]

Yes. One of the Great practical Engineers in this game. Leaps and bounds ahead of the rest of us. Did (still does?) some of the most innovative practical effects work in the motion picture industry. Pure genius!

Look at the size of his transmitter. I recall reading something about his sub having special features like a video camera in the sail, passive sonar and autonomous cruise control.

must be Rick Galinson.

I always liked the clear sub that was in the older Regattas. I do not know who made it, but I thought it was a great teaching tool.

Yes they should be-molds should be platinum silicone and vacuum degased -final casting should be done under pressure to suppress bubbles.

[Subculture]

Are the tools designed to be used with pressure casting- the clear resin usually requires it to ensure a bubble free finish.

[Bob Gato]

Its an evolution in design-I was thinking something that's bath tub testable and hatch back transportable ... somewhere around 1:50 to 1:72-although 1:64 is a kind of an odd ball scale it would be perfect.
I was thinking of clear resin casting each panel and bonding to clear interior frames but IDK how that would work out-the cast pieces would all need individual buffing. The most likely best practical would involve a mix of flat poly or acrylic panels and cast the thicker jewelry and scales from resin.

Scott is out of the Nautilus game and has been for ages. I've got molds. A clear Nautilus would be really interesting, but the hull is about 1/4" thick in most spots, so it wouldn't be "water clear". It's also a smaller(ish) boat. Not sure what Bob had in mind for a scale, but it's certainly an option to try. I'm willing to give it a go.

Maybe you could ask Scott Brodeen to cast you a clear cast version of his 1/69 Disney Nautilus.

[Bob Gato]

The light bulb in redboat's lamp above just went off over my head-"Water clear casting resin". How strong is it? those paperweights that you buy in the mall certainly seem strong- Simple, just cast the hull parts with that polyester crystal clear resin-yes internal support structure would take some thinking. And it might be heavy-no additional ballast required- I wonder how thin the unreinforced resin would be practical.

Scott -I have used Bondic UV cure plastic in the past and it works extremely well for rivets...as for panel lines, I would expect real separate panels.

So how about having a printer print on the rivet detail and panel lines on flat lexan sheets?
