RC Submarine Cylinder

Update, ESC is working, had not stripped power in wires long enough to power block... now, all electronics working, all fits nicely inside the 70MM tube....

[biggsgolf]

Everything works except the pump ESC, returning and ordered another

[biggsgolf]

Umm, forgot to shrink wrap pump terminals....

[biggsgolf]

Ok, all sections printed, all tubes, wiring, electronics installed.. now programming the TX. I am nervous


...

As I think I mentioned, I wanted to design a miter box to cut tubes. It has default 70MM, and has 18MM and 60MM inserts that screw in to threaded inserts....

[biggsgolf]

Cool!, yeah I went to plan "B", took pump apart, cut nipples shorter, epoxied fish aquarium elbows after resizing pump nipples.....

re-purposing my 70's forceps to align and tighten the control rod collars, lol

Since it is probable that water will sit in the resin 180 manifolds, I am aborting them, just not comfortable trying to coat the insides of them.. Working...

[biggsgolf]

Anybody used Dichtol AM Hydro on resin prints?

[biggsgolf]

Better pic of how they work.

So I want to eliminate the crimp in tubes that attach to this pump, so made "180 degree manifolds"

Here you can see the driveshaft alignment, perfect for the eventual coupler

Mounted the motor, servos, servo arms, driveshaft, and control rods with wheel collars for adjusting the control rods.

Yes, I designed and tested the end caps first. Took many tries, so the end cap design can easily be adjusted for another cylinder with a different I....

[biggsgolf]

I agree, thanks

So I have been designing a cylinder in part based on Ron's R&R Cylinders. I am building prototype for myself, and will use the STL files for a friend...

[biggsgolf]

Starting at the stern, first 3 sections attached with screws and threaded inserts. Motor attachment threaded inserts installed, pump, pump esc, and rx...
