Linear output on radial servo

[Ed Kirk]

Strange idea, why rotate linkage when the servo can be rotated. The idea came to me the other night to hinge the servo to rotate around the linkage....

I really like the shape and fit of the Typhoon. twin screws with shrouds, Never seen the real thing but got the classified brief - floating city, well...

Short, sport Typhoon next to standard size for scale. ...

I redesigned the ballast tank. the center section for the dry components was oversized and the O-Rings were not tight enough to seal. ...

[Ed Kirk]

Printed ballast shells filled with lead shot and resin and installed in hull.

Center hull section, left as printed. Right coated with white Seal Flex, great results, no way to test but looks promising since boayancy...

Something new growing from my printer. Pretty much sticking to original STL's, I am installing threaded joining rods, and putting motors...

[Ed Kirk]

Ordered some of this miracle stuff to seal prints. See how it goes....

[Ed Kirk]

Added saddle tanks to hull shell for single print, left room for lead ballast down bottom center.

Experimental prints in terra...

[Ed Kirk]

Printed some saddle tanks for buoyancy, snug fit, no room for lead ballast. Set in water very nicely but rolled over and went belly up.

[Ed Kirk]

Needed buoyancy, got some foam from Home Depot started to cut and hack some shapes - what a mess so I decided to print some blocks. Still experimenting,...

What a KNIFE! Donate to your local blood bank....

I did a simple pressure test on the 3D printed ballast tank/water tight compartment by using my mouth to blow into the tank - did not hold...

[Ed Kirk]

Yes, I know, I printed some shells for my clock projects and filled them with epoxy resin/lead shot and they leaked. Went to a two stage process - coated...

Printing new ballast tank, added two auxiliary tanks to displace water when flooded. they will be open (with a cap) on one end to allow...

It's in the water - kitchen sink- surface looks great, a little heavy aft. Submerged is very negative, need some foam.

I use Orca slicer to "Add Part" or "Add Negative Part" to modify the STL file. Mostly trial and error because the actual print...

[Ed Kirk]

I don't like the yellow - it's PLA glass filled, doesn't print well. Probably stick with white with red trim....

Finishing up and testing electronics tray, designed to slip into end of ballast tank. End cap and tray single print, keeps things tidy...
