Prop shafts and rudder
A hole has been drilled through the hull for the rudder, and a brass sleeve glued in, again with epoxy. To hold the glue in place around the brass sleeve, a little dam was built of 2 part epoxy putty. This allowed a nice depth of glue around the rudder sleeve to give it strength.
Sealing the prop shafts
Too get round this and ensure that there was going to be no leakage I’ve built a dam from epoxy putty around the shafts then filled the area over the shafts with epoxy resin. It took about 120ml to just cover all the shafts. This has taken 24 hours to cure, but flexing definitely won’t be an issue now.
The hull has had some spruce marks cleaned off and smoothed over with plastic putty, before having a wash in soapy water to remove any release agent. After drying for a couple of hours, it has now had its coat of plastic primer. Unfortunately the hull is too long to fit in my spaying cabinet, so cardboard and newspaper over my bench had to suffice.
A couple of superstructure parts have had their doors and grills removed whilst waiting for the hull to dry, and photo etched brass replacement fitted. These look much better than the moulded plastic.
Back half of the focsle deck
The first part of the wood deck has been attached, which should have extended onto the front section of the focsle deck, but that bit of the wood deck was removed. The front half of the focsle deck will be glued to the hull, while the rear 2 thirds of decking will be removable. The missing wooden deck part doesn’t show as it’s actually under the splinter deck.
To see the detail on the rear half of the focsle deck such as the hose reels, doors, vents etc it will be necessary to peer under the splinter deck, and may well require a torch to see the detail. Never mind, at least I know it’s there!
Deck in place
The anchor holes have had pieces of styrene tubing glued to the inside of the hull, and then 2 part epoxy resin wrapped around them. This should stop any water ingress, and will look good painted black on the inside, and the anchor shaft will slide up inside them. The tops were blocked off with a bit more styrene, and sealed with 2 part epoxy.
This allowed the front half of the focsle deck to be glued in place, and the wood decking affixed the length of the ship. There is no obvious point where the deck can be cut to allow access to the inside of the hull, so the rear half of the focsle deck, and the quarter deck will be connected together with the shelter deck ( not the splinter deck that I called it last time). This overlaps, so will make a nice joint and it will be reinforced on the inside to stiffen it up. This removable decking will be about a meter long, so will definitely need to get reinforced.
The shelter deck actually overlaps the front focsle deck by about 5 inches, and the bridge superstructure is on this overhanging part, but at least it will hide the joint between the fixed and removable deck.
Decisions decisions
As well as building this, I’ve been busy making dozens of little lockers, winches and ladders, and the wife kindly made 3 of the gun directors which were small and very fiddly. After some discussion I’ve decided that some of the very small photo etch won’t be used because there won’t be enough glue to hold them in place with the vibrations from the motors.
T.he motors that came with the kit from deans marine are too powerful, so I’ve ordered 4 geared motors that will be much better. These unfortunately aren’t a standard mount size, so I’ll have to manufacture some metal motor mounts.
Propulsion
Mfa combo didn’t have any mounts for these motors so I had to fabricate my own. I had some 380 motor mounts but these had a 10mm hole in the centre, so a 14mm drill was ordered from eBay. The mounts were drilled on my myford lathe, then the screw mounting holes were widened with a small file. So far so good.
When these newly mounted motors were positioned in the boat it came apparent that the prop shafts came through too low to get a straight run to the motors, so I had to use double universal couplings to keep them as straight as possible. It also came apparent that 4 motors wouldn’t fit alongside each other, so the rear 2 had to be mounted behind the middle motors. That would have been much worse if I had used the original motors which were 6mm wider.
This left me another problem. The outside propshafts flexed far to much, so a little pillar was made with some brass tubing passing through to act as a bearing. The supporting column was filled with 2 part epoxy to secure it and that appears to have made everything rigid.
First water test and more superstructure
The rudder throw also wasn’t enough, so some extra long micro servo arms were ordered from eBay to give me more rudder movement. What with the boat still too high in the water, it wasn’t a very good first run out. Hopefully this week, with the rudder throw sorted, a new receiver and a bit more ballast, it will work a bit better.
This week some of the superstructure parts that have been getting assembled we’re finally glued to the boat, but I’ve run out of grey paint now so bits will have to stay under coated until Wednesday when the new paint arrives.
Second water test and more assembly
The longer servo arms arrived but were too flexible so the current rudder throw will have to do. This didn’t seem to bad after all, and the arrival of the new receiver meant that the twin esc started working fine. I can now spin 2 props forward whilst the props on the other side of the model spin backwards. This really improves manoeuvring so I’m happy with all that now.
I received more grey paint, so many parts that had been assembled could now be painted, and some elastic rigging cord arrived, so assembly has really started these last few days. I have to say that it is starting to look really good and maybe another weeks work will see it completed. That will please the wife as she wants to start the Deans marine HMS Bulldog but the Hood is taking up all the working area.
I’ve attached a short video on how it is looking, and hopefully will get a video of it completed and sailing very soon.
a few close up pictures
Anyhow, here are some images, one of which is against a 2p coin for scale
