Articulated bow planes; opening flaps; working rear trim tabs; dancing girls and elephants! Its raining here today so I'm off to the shed to butcher some more renshape and start on the rear planes for which I actually have some good drawings. More later. Thanks for all the info men. I really appreciated your input and the photographs. Onward!Comment

Wet days are great on the farm. No guilt whatsoever about not doing any work - and, she who must be obeyed won't walk 300 metres through the rain to get to my shed. Heaven. Today's work.
I had to get a bit radical with the rear end because I had no really accurate way of checking the contour of the rear section. There is a 3 mm plywood stringer running down the mid line of this thing so I went all the way in there to get access to it and to use it as a depth guage for the tail planes. And it worked!

Its a very thin piece of plastic that I cut to the plan dimensions then sanded the renshape down to the plastic. (Old Merriman trick - performed by Old Merriman!). Provides a constant center line reference no matter how much you sand off it.👍 1Comment

I'm preparing the tail plane sockets tomorrow. I'm planning to slather some bondo into each of the sockets and oress the tail plane master into it. Prior to that I ground a bevel on the master and I'll coat it with some blue PVA so that I have some chance of getting it out of there and leaving a nice clean socket behing.
The beveled master root section;
Basic alignment check. Looks OK.

Good plan on the horizontal stabilizer parts -- indexing them to the stern with slots. This will make kit assembly all the easier, Scott.
I assume the sail will be a separate piece. If so, this will permit building up different units of the class. And the chin sonar dome -- will that be a separate piece? I ask for the same reason as the sail.

I was having a look at the sail this afternoon. There is a fillet at the base that runs right around the sail where it meets the deck. It appears to be too fine to add to the bottom of the sail unless the sail is first fixed to the deck. So the question is; do I fix the sail and make the fillet and the walkway consistant or just leave the fillet off and make the sail as a separate piece?
The chin bubble is fixed to the hull however its nothing that can't be removed with a belt sander if you really wanted to.Comment

what if your sail went on like your horizontal stabilizer does? A portion of the deck surrounding the sail remains attached to the sail and a socket is placed in the deck. Then another sail can be popped in. Not trying to make more work for you, just shooting out an idea.If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.👍 1Comment

And if the customer elects to keep the sail removable he gets easy access to the snorkel and any other mechanisms under the sail.
You can let the customer work out the fillet …. If they can't do that we demand they turn in their man-cards! Simply use a ball or dapping tool to form the fillet from Bondo:
Or, as you see here, there's no problem incorporating the fillet to the removable cast resin sail:

Oh wait, this is Scott, never mind, he can do it.Last edited by trout; 02-21-2019, 03:17 PM.If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.Comment
