Watch your linkages. Cup seals work best when the action is true linear. What you have is a closely set servo that will swing through about 100degrees of arc, moving your rods outward as you reach the two endpoints. This will create binding. Typically if you're going with that sort of setup, you'd have an intermediate shaft that is hinged just before where it exits, letting the actual shaft run straight while the intermediate accepts the change in angle....

Thanks! I will!

WOW! looks real nice! I wants one :) Thanks for sharing.

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. Will have RX mounted at bow end, only had to run one positive and one negative wire from bow to stern. Will work on power supply wire lengths next

[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

[biggsgolf]

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. still need to mark cut line on tubes and rotate tube as I cut them. boxes screw to a level surface or 2x4, allows for varying lengths of tubes and has a solid insert that goes in first then whatever size insert to give tube a "stop" to prevent it from moving to the left, since I cut right handed. When cutting, will not use the grooves on the box, will use the outside edge of the box.

Look up Silicone right angle or elbow connector for irrigation.

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

[redboat219]

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

Look up Silicone right angle or elbow connector for irrigation.

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

[biggsgolf]

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 on making a resin printed miter box for cutting the cylinders

[biggsgolf]

Anybody used Dichtol AM Hydro on resin prints?

Better pic of how they work.
