Fascinating stuff Chris.

Are you on another forum where you show these projects being built?

Or are you just teasing us?
I've written up these unusual ones for the quarterly report of the Subcommittee, which is a forum and club for rc submarines. You have to be a paid member to get those reports, the group sponsers meets like our big one in August.


The teasing is just a bonus!   :LittleDevil:

May we have some MORE please Sir?
Lots more?
That is fantastic, I had to go change my shirt, luckily I am on my laptop and the keyboard stayed dry.

We'll have to get you a waterproof keyboard!   :Lol:


I'll be posting more on it soon, am making a big push to get the sub done before the end of the month.

Hi Chris,
 Oh I do like these side tracks you keep throwing in! That turtle is going be neat to watch!

Is that a pile of Stanley engine drawings I spied under Turtle?

Cheers Kerrin
Get excited and make something!

Yes, those are the engine drawings for a full size Stanley motor, wondered if Zee would see that and yell at me for not making that instead!   :Lol:   It was going to be the current project, till I found out about the Marion here. It is next in the queue, though I'll be making it as a scaled down engine rather than the full size (too big for my lathe).

Wait, what was that last one? Oooh, gotta write that one down!

Zee, you have a nice new shop, I can send you the plans to start it yourself while you are waiting!

So, while security escorts Zee off the premises, while making notes on the words for their next union meeting with management, here is a short video of the gimbal mount for the submarine props. Got the rest of it made up today, ready to mount onto the tail of the sea turtle.

As mentioned before, this week is diverted from the normally scheduled build of the steam shovel to get the new sub ready before our next RC sub run at the Y pool in a couple weeks. Sorry for the delay on the shovel progress, but whatta-you-gonna-do, too many hobbies, not enough chocolate chips!   :shrug:

But I know what you mean about having a bunch of hobbies. My problem is...I finish nothing. I enjoy the road too much.

Up at the shoot tonight, was talking with one of the guys that is big into old cars, steam engines, etc - turns out he has a real engine out of a Stanley steamer, complete except for missing one cylinder cap. Gotta get over and see that...
And, unless the really unlikely happens and I find out about another big steam machine in town again, the Stanley engine is my next build. Most likely. I think. Probably. For now....

That sounds like a good reason to get a larger lathe, one can never have too many tools.

Got plenty of tools - a big lathe and mill would need a new room added like Zee did! Or convert one of my other shops to a machine shop, then I'd need a replacement room for THAT shop... Then need a place to display the bigger engine, so another room for THAT... Sigh. Never ends!   :Lol:

Today's update for the sea turtle RC submarine (again, apologies to those tuning in for the Marion build, I am sidetracked for a couple more days on getting this sub knocked out for a run coming up soon, be back on the Marion by midweek at the latest).
The rear fins and the prop gimbal mechanism are complete and attached:

Just epoxied in the pivot bearings for the front flippers, also completed the control horn and stop collar on the flipper shaft:

The holes you see in the bottom of the shell are fill/drain holes - almost all these subs need them to let the water in/air out as it goes into the water, opposite when taking it out of the water. The hulls free flood, and there is a water tight cylinder inside for the motor/radio/batteries. Otherwise, the hull would have to be a lot stronger, and would need a lot more ballast to get them down to a decks-awash (in this case head-awash?) state for further diving. Some of the models, mostly those with internal ballast tanks that can take in/pump out water, do have a full pressure hull. This type, called a dynamic diver, does not, and needs forward motion on the dive planes (flippers) to take it the rest of the way under the surface.
Anyway, here is a shot from the head end, the head was attached yesterday. Something not usually seen, a sea turtle up on jack stands for maintenance! 

The top shell slips over the base plate, and has locator pins with little hitch pins to hold it in place.
So, the 'hull' is about done, time to move on to make the WTC for the electronics - that will be from clear acrylic tube and sheet....

This morning I gathered up the parts that will go in the watertight compartment of the sub, started laying them out on the table, and quickly realized that to get them arranged in a small enough package that it would be best to lay it out in 3D. So, modelled up the parts as outline bodies in Fusion, and spent some time rearranging them till it all fit in a short tube. I have some 4.5" OD polycarbonate tube and some 1/4" flat sheet stock that it will be made of. The servo tray is plastic also, and will be attached to the end plate with all the thru-hull fittings, so it will all come out in one piece with all the servo rods in place.


The green boxes are the servos, red is motor, blue is battery, brown is speed control, yellow is reciever, dark green is switch, and the fittings at the bottom right are the motor and output shaft pulleys, thruhulls, and the motor mount plate, which allows for tensioning the belt.
Should all build fairly quick, done several of these in the past, and I have the thru-hull fittings already, made a spare set on a previous sub build. The polycarbonate tube needs some flat blocks milled and bonded to it to give enough thickness for the bolts to hold the end caps on, which will have rubber gaskets to seal it all up.

Hi Chris ,interesting stuff going on there...That was my job in the army as a control equipment technician !! no gyros though to stop it flipping over !!!
