    Laziness. The o ring groove was too shallow. No lathe here , so went silicone route. Will see how it survives
    Next time someone points out it takes 42 muscles to frown, point out it will only take 4 muscles to b1tch slap them if they tell you how mnay muscles you need to smile:pop

      If the o-ring groove is a bit shallow for existing o-rings, then you might might find you can use another size. e.g. you can swap imperial for metric o-rings and vice versa. Gives a bit of wiggle room.

      Silicone rubber o-rings also squish down a bit easier than nitrile/buna-n, but have greater tensile and shear strength than silicone caulking, which has all the strength of wet pasta.

        There's no forces on the silicone, and the o ring section is already pretty small. Let's see how it goes

          No criticism, laziness is perfectly acceptable. I had repaired an old wtc from a well known submarine pioneer here in the USA and he also used silicon to fill the gasket space. It worked well for him!
          If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

            A bit more work to train the wires to go in the right direction when I close up. Also have a compatability issue with the level control. When that is connected , the dive plane channel stops working but is powered, but more weirdly the rudder and throttle channels swap over!!!!! So the leveler is out for now, but it will eventually fit between the linkages.

            Hopefully I can fix the issues in the week and get it wet next weekend

            Btw I do know that the shaft seal is missing. I can't find that size here, so may have to fit a metric one for now and not run the motor, feels a little tight on the shaft.

            Andy if you are reading this, anywhere in UK that does 3/16 seals, I'm over next week and could pick some up.

              Simply bearings is good for small oil seals. they have a couple that may do the trick, on at 0.18" and one at 0.188". So a bit under or a bit over.

                Romel, I think this thread has what you are looking for

                Dave - The Red cross care packages arived, thank you VERY MUCH, those are real small section seals, and the bearing will provide some support !!!! SWMBO imposed a strict work roster this weekend, lots of clearing out, so other than soaking some oil into the oilite (or whatever it is), i didnt get much time for anything

                BTW this new website is giving me a headache, sorry for being a wingeing pom

                  Glade you got the goodies. You should not need to pre-soak the oilites, they're packed with oil as is.

                  Yesh, the 'new' forum is an aquired taste. No?
