Anchor winch

The frame work for the anchor winch came next.

This piece was formed from the aluminium off the bottom of a Pringles tube by working the web out with geometry.

The failures...

And finished in place

The blocky upright shape is a cable cutter, basically a big wedge that you hit with a sledge hammer to cut the cable.
Also at the starboard side of the aft deck is the main winch.

Going to have to do something about that bit of warpage that's crept into the aft deck.

Anchors and bits

The main kedge anchor. The LCT would drop anchor on the run in to the beach and then reel in the cable and put all three engines in reverse to get back off the beach.

Railings - showing my shortcomings when it comes to soldering. After two or three goes I decided to stick with styrene.

Anchor Skeg

Wasn't sure about how I was going to do this.

So I worked it out on the flat first from plastic coated soft iron wire. You can glue this with cyano-acrylate, and trim he ends back to make pegs. I made it in one piece and made the biggest hoop solid.

Then I disengaged it fom the plan and trimmed that piece of card down to size.

Once I had the template, I added double sided tape and placed it on the back of the hull.

I used the template to drill the hull, and glue the skeg in place.

Then out comes my friend Mr Dremel!

And now for the pack shot!

Deck fittings and trim tabs

Quickly through some of the deck fittings

on the foc's'l - the cable guides for the ramp cables.

mid decks for refueling

This photo of an LCT being loaded onto an LST shows the framework, I think it's called a skeg, around the anchor. It also shows trim tabs - that stop the hull digging in as you apply the power. They weren't on the plans, but they're now on my model.

Prop shafts and tubes

The servo
/motors will drive two 2mm shafts going out of the hull through the double walls, but at the outboard end I planned two 'packing tubes' (see? - I have all the lingo down) filled with grease as extra insurance.

Start with 3.5mm brass tube cut to length,

Clean out the burrs
Photobucket

Punch out two discs of plastic card - these double as the end seals and bearings.

Plug the ends of your packing tubes.

Centre the discs and mark with an awl.

Drill, display, test and fit.

Wet wet .... well you get the idea.

Flotation tank tests (In the bath).

More doors and stuff

The crew accommadation doors and deck hatches.
Actually those doors are going to get changed - I got hold of some etched brass doors. Later lesson.

Sometimes it's important to put it all together and just look at it.

Getting through the pictures.

Due to recent interest from Hat's forum I feel I should get a move on with these pictures.

So now the bluwarks are on.

The braces for the bulwarks had to be changed when I had placed them all I went back to the pictures and realised that the braces only come out halfway across the deck. B*gger!

So they all got trimmed back and re-glued. Much better.

The ventilators came off the Airfix Vosper, they could have been bigger but there are images of some similar in size to these. All idid was fill the joins and burr out the walls so they were more of a scale thickness. So a couple of advantages are easier to get hold of, and easier to replace if (when) they get knocked off!
