The reason this build is taking so long is simple – I just haven't been working on it. I tried a few little builds to get me back up to steam but they only distracted me even more. I can't really focus on 2 projects at once, I'm a one track kind of guy. Can't walk and chew gum at the same time.

I've had a few sessions back on the Maui and there has been a little progress. Not as much as I'd like but still progress. You can only eat an elephant one bite at a time, and this build feels like I've still got most of the elephant left in front of me.

At least I've finished the stern fender roll. At last!

The fender has been held on by various methods over the years – wire ropes when I visited years ago. I decided to use a combination of wire and chain. The chain feeds through the hull and is fixed so that it can be released and replaced easily.

Wasn't as easy for me as I had hoped but worked out in the end. Now, more elephant Vicar?

Back to the elephant buffet...

I usually approach a big build like this as a series of projects. That way I can focus on one particular aspect of the build at a time, get something done and feel a sense of achievement. It breaks up long builds into bite sized chunks, and near the end of a project I can just assemble all of the completed components. I’m pretty sure everyone else does it this way. The trick for me is to figure out some sort of order that things need to be done in.

The hull is at a stage where I can set it aside for awhile. Still plenty of deck details like vents, pipes, bollards, etc, to do but they can wait. Next task is the funnel.

Maui’s funnel is quite a pleasing 1960's shape but it has had lots of equipment added on over the years: nav lights, aerials, radar, fire-fighting equipment, horn, rails, vents, drains, etc. There are bits and pieces poking out all over it. Some items need to be dealt with first as they will be difficult to attach later. Some of them will need to be pretty robust as I tend to knock things off on a regular basis.

Relax – I’ve had years to think this through.

I had made the funnel base way back in 2021 and on closer inspection it needed re-shaping. The rear curve of the ‘as built’ funnel was significantly different from the drawings I had. My version was close but not close enough. Easily sanded down to the correct profile.

The rear edge of the funnel top section has a rolled lip all around it. 1mm stryrene rod did the trick. At the top it curves up and under the Y shaped stalks.

There’s a large air intake on the starboard side only. The louvres came from the spares box and were pretty much spot on width wise. Easily trimmed down and slanted.

The exhuast bases go in now as they’ll be too difficult to access later.

The collar is where the mast top section is bolted onto the lower section. So far, so good. Looks a bit like a giraffe at the moment.

Next job is all of the large components that require a bit of work and serious attaching. All comlex and fiddly and each bit took about a day or so. It took ages to cut and file the tiny slivers of brass tube to make the sprinkler piping collars. They are 2mm x 0.7mm. Even tricky to hold onto.

Anti-clockwise from left: engine room vent, radar base, reshaped funnel, fire fighting sprinkler system, hatches, exhuast pipes.

The W47 build is winding down/up so I've made some slow but steady progress on Maui. I've accepted that this is going to take as long as it takes. No point rushing things this late in the day.

The ladder rungs took ages to get right. Each flight is a different width. Would have been a whole lot easier if I hadn’t bothered with 90º step down on each rung.


A little sanding and then some paint.

Now that W47 is all finished I can get back up to speed on the Maui again.
[/size]
[/size]All the pieces from the last post have been painted and attached them to the funnel. These items all need to be securely attached before any mast equipment – and there is a bit of that, can be glued on. The mast arms and FF piping are all pinned into the main mast, and everything has had a light top coat of paint.
[/size]
[/size]The black hides a lot of the hard work but also some of the mistakes. The equipment (radar, antennae, horn, work and nav lights) will add a bit more detail and colour.

The mast has a few pieces of equipment: radar, antennas x 3, horn, nav lights x 5, work light, and some kind of loop antenna that I don’t even know what it is. Could be for mobile phones?

Anyway, at 1/50 they are all small and difficult. So I started with the most difficult – the loop antenna.

Seems simple when you look at it – 2 semi-circles stuck to a hub.

The thinnest rod that I have is some Albion Alloys 0.2mm silver nickel. Almost ideal size for the semi-circles, but it’s very difficult to bend into tight curves. Very.

I made several jigs to try and gently and smoothly bend the rod to the right diameter. The first attempt was to make a semi circle with radiused ends. Easy to do one but very hard to get 2 completely identical. Easier said than done. At this size half a mm difference stands out like the proverbial. Made about a dozen before throwing in the towel.

The next idea was to make a circle around some correct diameter dowel, solder a piece across the middle, and then cut off the excess. Yeah, nah! Messy.

Next attempt was to form a semi circle, clamp it into a jig and solder the cross piece. Went through about 5 different jig set ups before I eventually got one that worked. Very small, fiddly and frustrating work – but, bingo! Two semi-circles almost identical. Close enough.

It’s the larger one on the right. The other one is for another project.

After finishing this I decided to try and find some 0.1mm rod and re-make it.

By comparison the radar, horn, deck lights and nav lights were almost a piece of cake. Almost. The black paint hides a few sins.

In real life there is a chunky collection of messy wiring all up the port side of the mast. I'm still undecided if I'll have ago at that.

In real life the radar has no maker’s logo.

The antennae (yes, they are all different lengths) are not glued in yet. That won’t happen until the mast is attached, and that won’t happen for awhile. First, I need to tidy up the superstructure, attach any items that can’t be painted later, then glaze the wheelhouse, and then attach the roof – without messing up the glazing. Once the glazing is done and the bridge roof is attached any filling and paint retouches on the superstructure will be very difficult. Should be done by dinner time.

I could learn a thing or two, about taking the time to make jigs.  ok2
 
Great work on the mast and all those fiddly bits.

Thanks Aimee. Making the jigs doesn't take any time – they are short term, one time only use. They look rough but work fine. Some are more complicated, some very basic. Makes repetitive work, and delicate stuff much easier. On a long build I end up with more jigs than an Irish pub. Must be in my genes  ok2 .

Learning how to do 3D printing, like you, would probably make all of this even easier, every build needs lots of identical or very similar items. I hate to think how many lifebuoys, life rafts, anchors, vents, and nav lights I've had to make over the years. Did I mention that I hate making nav lights?

What's an easy starter 3D drawing program? Got to be free, and Luddite friendly.

I have been using Fusion 360 for the hobbyist.
I can't emphasize enough, Free for the Hobbyist, as Autodesk wants you on a free Trial, which will expire.

I also just found out that Blender is a free open source software. I have seen a lot of
great things produced by people using that software, but have yet to check it out.

Before I start any glazing, the roof section needs to be ready to just drop into place once the glazing is done. I need the roof off to do the glazing. It’s a tight fit and not much leeway for painting once glazed so I’d like it just to drop into a very tight fit with little or no filler and airbrushing.

The ply base gives it a bit of strength and keeps it straight and true, the styrene skin gives a good surface to work on.

The deck, inner of edge lip, and the stanchion bases are all same colour. The circle is the binnacle base. This needs to be painted before being glued in.

The colour is the same as the hull orange. I painted the hull 4 years ago and didn’t have any paint left over, also, I never wrote down the formula. Had to mix a few trial colours before getting a good match to the hull. Yes, I mixed plenty this time. And wrote down the formula in case I’m still working on it in another 4 years.

Great to see the forum back in action. Had me worried for a minute. Thought it might have gone the modeltugforum route. Stay healthy Martin!

Slow but teady progress on the build. The superstructure is at a stage where I can add a few bits and pieces and give it a light top coat of paint before I start the glazing.

Various vents, doors and window frames ready to be painted and attached. Some of you may have spotted that the 'wooden' door in the first photo is different to the door used in photo 2. The real door has a much bigger pane than door 1 so I needed to make a new door out of 2 spares. No biggie.

Everything secured and ready for glazing.
