[He Who Shall Not Be Named]

Hummm.... making suggestions to improve the camera work would imply a veiled criticism of the cameraperson which is somewhere that I'm not brave enough to go. She's fair, but cruel. Interesting ending however. The fore planes are very sensitive and I dialled in a bit too much speed just as she dived. Looks like she did a torque roll and a tight, right descending turn. As I pulled the rear planes up it made the turn tighter and she went to the bottom (about 20 feet down). Lots of bubbles and then....stillness. Fortunately she poped up about a minute later when the ballast failsafe activated, covered in mud and weeds but otherwise OK. The down side of operating in my pond is that if I loose a boat there its not coming back in a hurry. Its dark and deep.

Whew!

Glad.

Roger that about the Camera person. Carry on Sir.

Some vido of the Akula in the pond at Ourimbah. https://youtu.be/JrdQgJW_Jjk

Did you get it back!????.....

Thank you Andrew. She runs well. Maybe next time your camera person can zoom that I-phone in a little. I assume it came back up.............somewhere

Working on the front end today.



The mounting for the fore planes does double duty as a torpedo tube mount. The whole thing comes out for maintenance and is held in place with two allen bolts. Neat!

[HardRock]

Surface "TRIM"; not surface "trip". Also forgot to mention that the the photograph above does not show the foam which fits over the SS nuts at the end of each arm. When the boat is submerged the form exerts an upward force on the arm which keeps the bollards retracted, as the boat surfaces the water level within the hull drops; the foam stops exerting an upward force; the SS nuts exert a downward force and the bollards rise. There's a drop of silicon oil in each bollard housing that damps the up and down movement so that they are not going up and down like a fiddler's elbow.

[HardRock]

I fitted an automatic system to the Akula that pushes the bollards up when the boat surfaces and reaches normal surface trip. As she submerges the bollards retract so that by the time she gets to decks awash they are completely flush with the deck.



As an alternative I might make these hydraulic. All the masts and doors are going to be run by a pump and valve system so it might be relatively simple to hook these up as well.

[greenman407]

Do you have a system to move them up and down or are they going to be moved manually?

[HardRock]

Doing the bollard thing.

Great video. Wish I'd had that photograph before I did the hinge. It would have prevented a lot of colourful language.

Thanks Men. Looks like this thing extends quite a bit further than my plans show. There also appears to be a flap below the main hinge point that opens outward (which would make a lot of sense since that hinge is a complete *******).

Same principle as the missile hatches on the DELTA



I found a Video of a DELTA where the Cod Eye hatch opens up (@ 0:30 and 1:22)......but no cigar is rising (but I believe it differs from the one of the OSCAR anyway)

Do you have a link to this video Bart?

Yep...I believe it's an OSCAR (I).....image is @7:40.

Forgot to add the photo.

Sweeeeeeet. I always wanted to have that one operational on my OSCAR, but had to give up on it to get all the other mechanics to work with the scheme I came up with.

I still owe you photos of the insides of mine - I haven't forgotten, just been delinquent.
