And I thought I worked hard. This is what keeps us going. Good hard work! Love the new MSD. I have one right here!

Baby powder, soft towel and a good night kiss, that's one pampered baby. I bet you read it bedtime stories and sing it lullabies each night.

David it's just smart and worth the extra effort. I'm building a cylinder where I'm doing the same thing. I'm making double ended end caps so everything is modular. Your end caps are deep too and extend further inside than other previous modular designed WTCs which prevents any separation when handling the cylinder. My old BigDave cylinders had this problem and I use to have to hockey tape them together to stop this from happening. Double o-rings too. Very nice!

David, I know I say this a lot, but your work is simply amazing. I wish I had a time machine and could go back a decade or two, just to learn from you. As it is, I will absorb what I can from these photos.

A quick recap:

Bob Martin and I have collaborated in the development, production and sale of an improved SubDriver, the Modular SubDriver (MSD). A system that controls, propels, and manages the variable ballast water of an r/c model submarine.

The MSD's advantage over the other system is the interchangeability of the three spaces -- one at each end which are dry, and the center space comprising the ballast tank. Whereas the SubDriver employed only one length of Lexan cylinder the MSD uses three lengths of cylinder. And the MSD does not make use of any mechanical fasteners to hold the internal bulkhead in place -- those bulkheads replaced by unions that permit like or varied diameters of cylinder to be joined as a unit.



The three cylinder sections are easily removed this permits easy access for adjustment, replacement, or normal preservation. Each cylinder section is cut to the ideal length to fit the boat the system will be used in.





I've provided for the use of three different diameters of cylinder -- the diameter selected for the three sections can be constant or varied depending on the size of the model as well as its length-to-beam ratio. The diameters available are 2.5", 3", and 3.75".



I've been at this project for over a half-year now and am nearing the final refinements of the MSD. Additions to the system that further increase its utility, no matter the application. A gear-splitter to develop two counter-rotating shafts from a single motor is one example.



The last of the work is development of masters for unions and bulkheads that will adapt 3" Lexan cylinder sections to the system. Here's that work:

Not currently -- poor kitty!

What's the last thing a cat hears behind a Chinese restraunt?

"Here, Klitty, Klitty … Klitty"

Ewe! I don't eat cats. Or dogs, or at Chinese restaurants.

Accourding to SWMBO the mohawk haircut was better, are those the remains of the cat on the plate?, very concerned about that grin on your face, glad we have a lock down so i can't get over.

PS i hate to see such nice work.

LOL! Silly silly!

Talk about eating and sleeping your work! What can you say!!!!

Stay safe and take care,
