    Thanks for All your time to answer us.Some more questions. Why did you go with the plastic tube as your container rather than a temporary made rectangular box with the mold then being two pieces? IS that aluminum rectangular strip with the squares and circles home made or bought? Last, in the picture with the tail piece being removed there is an oil bottle with a syringe needle,used in the process?

    Thanks again Teacher Sir.

    Sir question about how you poor your resign into the molds for your 1/32 torpedo. Do you just mix an poor into the canal and let gravity fill it OR do you high speed spin it in a machine OR do you use a syringe filled with resin and force it into the fill canal?

    I use the Alumilite polyurethane casting resin. When mixed it has the viscosity of milk and easily fills a tool. With little trouble as long as the tool has adequate sprue, riser, and vent channeling to not only introduce the resin, but to provide a reservoir to account for crushed bubbles, and for the escape of displaced air from the tools cavities as the resin is introduced.














    I pressurize the work while the liquid resin changes state to a solid, this crushes any bubbles in the mix or bubbles entrapped in the tools cavities. The make-up resin is provided by the riser cavity.

    I've also spun-cast resin for special projects. But most of the time it's a simple gravity pour.

    Yes, I eventually want to do in 1/32, what I did in 1/96 years ago:

    I assume its for the stern light. But, it's open, I've never seen this 'notch' with a clear lens in place.

    Tom, I would be happy to do so. Drop me a PM reminder on or after the 20th ( I'm a teacher, and that's the start of winter break) I have a terrible memory and we're working finals.

    I too have been looking at converting a Revell Gato.
