Hi,
Forgive me if this topic has been covered elswhere. I am planning a scratch built Slava Class Cruiser, she is fiited with four stabilisers and I would like to have mine "operational".
Would anybody have any tips or tricks for ensuring that the stabiliser shafts remain watertight as they penetrate the ships hull?
Thanks,
Andrew

Yep, RC - 1/72 scale
Ply on Frame hull, Fiberglassed inside and out

PS thinking of short stuffing tubes and inner shafts - sort of like rudders on their sides.

"tube & shaft" works for rudders because normally the top end is located above CWL and movement is limited (nothing rotating).
For a working stabilizer I would opt for a solution almost similar to prop shafts. Though the fins will not rotate, they are indeed located way below waterline. My "minimum-solution" would include a tube, watertight and stainless ball bearings and inside the hull a teflon seal made on a lathe to fit.
Good luck - and please let us know how you did it...
Peter.
Hi Peter,
Thanks for the advice. I agree with you. I am "thinking" about small prop like shafts inside a stuffing tube, sealed either end as per a normal prop shaft. Depending upon room and angles, I might be able to have the inboard end of the tubes above the waterline. We will see. When I get back home, I will hit the drawing board and see what we come up with.
Regards,
Andrew

Thanks Peter,
As soon as I have a concept drawn up, I will certainly send you a copy. In the first instance I don't expect to be using gyros. At first I will rely on a mechanical link between rudder angle and th epostion of the planes. Just for fun.....
Regards,
Andrew

hi there, Andrew
You could connect them up to the rudders so that when the rudders turn
he stabilisers work against the usual swing of the boat
If you check here soem of the guys have done it

Hi Colin,
Thanks for that.
I was thinking about linking to the rudders.
I messed up my registration on the forum so I am trying to get that sorted out so I can check out the threads. (I hit the born after button instead of the born before button)

Tico give John Slater a PM on the TF72 site I think he has done working stabilizers on some of his models, he mentioned in one his post's about using a sub leveler on the stab's.
So might be good 2 give him a yell.
