Piston ballast tank vs Floating piston ballast tank

[Monahan Steam Models]

Currently waiting for new bits and pieces to arrive for the next rounds of torpedo designs and testing. In the meanwhile here’s a video of a marine...

That’s great feedback and exactly the info I’m looking for. Thank you!

[Monahan Steam Models]

Trout,

Thanks for posting. Is your SWM’s wtc functional? Have you had a chance to test it?...

[Monahan Steam Models]

Yeah, that was what I was curious about. Seems like the same pressure problems of a regular piston cylinder only more compact in the way I was thinking...

[Monahan Steam Models]

An example in this video of what I am referring to as the floating piston ballast tank type. This one is neat because it is a twin cylinder on one pump...

Manfred, Thanks for sharing the great background history of your VII. It has a lot of special meaning to it. Very neat. I ran across the videos you made...

Hey Everybody,

Does anyone have some first hand experience they would like to share using floating piston ballast tanks? I find them interesting...

[Monahan Steam Models]

Not too insane when you boil it down to the basics. Let’s look at it mechanically for a sec. Can you fit two 4mm motors side by side in a 10mm space....

It was weird, they shipped the 5F caps by air today but would not ship the 25F caps by air. Oh well, the design is starting to split paths. I have parts...

[Monahan Steam Models]

I can not say it enough, really great work! Your craftsmanship and attention to detail is amazing. By the way, your type VII looks awesome in the background....

[Monahan Steam Models]

Okay that’s cool! Thanks for sharing this! Btw, I ordered a couple more super caps today. There’s a few 3v 5F’s on their way and a few...

Manfred, thanks for sharing your experience with torpedoes. I really enjoy seeing your build posts and the progress you’re making on your projects....

Quick Update:

Just ran a couple more tests this morning with the largest 3 volt 3 Farad capacitor. This time the capacitor was connected...

[Monahan Steam Models]

Thank you sir!

This has been a fun design study and I hope that some of the information adds to the library of knowledge already out there....

[Monahan Steam Models]

The various super capacitors I ordered earlier this week arrived this evening. I was anxious to see what they could do so I did some rough bench testing...

[Monahan Steam Models]

Very nice! Awesome work!...

[Monahan Steam Models]

Thanks BG! I was definitely happy to see the speed return to the torp again. There are still more revisions to come before I’d say the design is...

[Monahan Steam Models]

I was thinking of using a reed possibly too! Nice! I was hoping the parts would show up today but it looks like they didn’t go out last night and...

[Monahan Steam Models]

BG,

I was thinking about other design options last night regarding the use of super caps. The drawback I see to running caps in series...

[Monahan Steam Models]

BG, we must’ve been posting at the same time because I did not see the link in your updated post. Thank you for posting that, I will ask my buddy...
