VINTAGE RUNABOUT

Made a run to the big Spotlight haberdashery/hobby and everything else store store today to buy some more black 3mm felt to line the inside of the cockpit. While there I spotted some ribbed black material which almost exactly resembled ribbed marine carpet, and it was on sale. There was only a metre left, so I bought that ($9,- normally $24,- cheaper than buying .5 m) and it looks spot on in the boat, (only used about a sq ft, so now have a lifetime supply,- perhaps I can cover my boat storage shelves😁)

Also made the dash panel which is held on with 2 7mmx3mm neo magnets (one each side) so it can be removed to access the front compartment (BT board and RX). If it wasn't removable, you would not get your hand in the compartment. Probably still be able to have dash lights, as they can be fitted in the bulkhead behind. It will hopefully have a few back-lit gauges when finished. Drilled a hole in the rear bulkhead for, the smoke tube, and made the brass T tube to link the 2 exhaust pipe smoke nipples.

If I get time, I might glue the exhaust pipes in permanently, hook up the plumbing, and give things a try. Getting closer to fitting the deck, but making sure everything will be reasonably accessible for repair or maint once its on. Getting pretty crowded inside now, so takes a bit of mucking around to get things in the right place. I've made the main electricals modular, so they can be removed easily. Various items ( RX etc) are velcro'd on for ease of removal as well.

The skipper's arrived and been dressed to match the boat. He looked a bit of a 'nancy' so I added pair of glasses to 'straighten' him out slightly. Worked out very well scale wise (if the boat was 18ft) and is quite good quality (Ali Exp) His missus should be arriving soon, and hopefully will match ok. Almost everything is sorted now, including plumbing, and it's just about ready for decking or hull painting.

Water/air/smoke system is working, along with the BT/SD card stereo. Same setup as the Hartley cabin boat, with radio and Micro SD card, playable from a small BT player/watch/phone etc, or on board Micro SD card using an IR remote. Had an issue with the high voltage brushless ESCs not liking being on the same power source (dual distribution board) as the water pump and glitching themselves and the sound unit badly.

Fixed that by running the pump from the smoke/air battery. Same set-up as my other boats, but these ESCs obviously don't have very good noise rejection abilities, (motors and sound even still 'tick' when the servo driven power switches operate). Just sorted out the starting sequence for the air/smoke timer and sound set-up as well, (short vid)

VINTAGE RUNABOUT

Did the gauges last night and started the windshield frame. Gauges can be back-lit but I might leave it for now. Lighting can be done at any time, as the dash is removable for access (held on with magnets) to the front compartment I've run out of switches on the 6ch TX, so lighting will probably just be a micro manual sw (for nav lights as well) I have some nice micro dip switches which are perfect for switching small voltages (LEDs and the like.) Used them on my Broads cruiser (see pic 1) for independent cabin/nav lights. Can be purchased with different numbers of switches. Photo of dash lights is a bit bright, due to using an LED torch to demo.

Won't complete the screen till the deck is on, due to the deck curve needing to be final (for screen base)

A bit more work on the dash and screen frames. Frames are just being cut to size and will wait for the deck to be attached as mentioned. Will have to be built from the bottom up, a section at a time. Side frames have been partially laminated in Mahogany. I've made a wheel as well, which was made from brass wire, wound on a pipe (as you would a spring) cut to size and ends line up and soldered. Spokes are brass sheet, shaped, bent drilled and soldered to the rim.

Dash has glove box and knobs added

    Re Hi there where did Mr cool come from?

    Ali Express Mike, about 1/10 scale, you have to take him shopping for clothes though (Ali Ex as well) but make sure you do it in a manly way😂 Search for male ken doll and male ken doll clothes (same for female)

    Thanks Colin, hope it's not a submarine with all the extra bits.😁 Wheel could have been a bit larger I think,- looks more like a power steering wheel, (could say it's been retro fitted😉) but easy enough to knock up a bigger one if it annoys me enough. Still a way to go yet.

Unusually nice and warm today, so a good day to throw the deck on, after making sure everything would be reasonably accessible later. Used West epoxy with glue filler powder and fast hardener and got to gluing flat out. managed to get the deck all strapped and clamped before the glue went off (just) so hope everything stuck, a lot of rails to apply glue to. Always fun doing a 'onesie',- having to make sure you haven't missed a frame or glued something you weren't supposed to😀, and to get it tied down in time.

I used front and rear locating pins to make sure it was lined up correctly, - makes life easy and eliminates any movement. Sanding tomorrow and maybe into bit of painting.

Deck's on and edges sanded, dash clear varnished, (holes to tidy yet) steering 'column' made for wheel shaft, (wheel turns) mahogany trim on wheel spokes, IR sensor extension for BT music player (mounted above speedo) a bit more screen frame work, (mahogany glass stops) and another coat of mahogany stain on the transom. Almost time to start painting😊

Threw the primer/sealer at it yesterday and started sanding it. I use a very good product by Zinser which seals f/glass from bleeding spots into the paint (usually happens as the wax can sit in tiny pores, no matter how much you de-wax it) This stuff works on anything interior, but I've found it's perfect for boats and planes under or over most paints to hide and seal the original surface, - especially balsa. Can be painted with anything as well, as it's shellac based and sets quite hard, Takes a bit of sanding but worth it. I spray a lacquer undercoat sealer on top, as a softer cover to sand back smooth, before the topcoat.

I think it was Australian as 'Bulls Eye', but seems to be now under the Rustoleum (US) brand (may have been just made locally down here in Aust by Zinser)?

    BIN primer is very good stuff! I have found it to be very useful on #D printed items, particularly some of the Nylon type of materials. I have not tried it on the "fine detail" plastics, but if I have a piece that I can afford to throw out if need be, I will try it a post the results.
    It sands much like automotive filling primer in that it is sof, but thick.

    TDog, the spray can sprays on quite thickly, - probably due to the coarse nature of the paint needing a bigger nozzle,- but I found this particular formulation quite firm to sand - being shellac based, (not like soft car primers) The brushed on (can) mix is slightly softer. Excellent stuff all the same, and covers better than anything else. The grey primer I've just sprayed on, (INOX industrial ) dries very fast and sands like butter, (barely have to touch it with the paper) Great for building up coats.

And now for something slightly different. Finally managed to get a slightly warm day, and decided to do some painting and staining. Still have the bottom to do, and clear varnish the deck and transom. Screen needs finishing, as well as a few deck fittings and spray rails etc making, - also some interior stuff. Saw a late model Chris-Craft this colour and liked it.

    Hi Stephen, thanks, - black's always a pain as it shows everything, but I'm not too worried, as it's a stand-off type model, (a long way of) and won't show too badly out on the water. Have to cut the black yet, and that will make a difference. Needs a break between the black and red deck I think,- some sort of moulding or a thin mahogany strake perhaps, but can't get out for 2 more weeks (lockdown) to have a look for anything.

    May be longer before I can go to the model shop (which will probably be short of stock anyhow, like last year) and look for some long strips of hardwood I can stain up. A lot of bits to go on yet, but no way of getting material of any sort at the moment, - not even glue. Luckily I stocked up on glue and balsa before this, so good for a while. I will need some Cyano gel which will be a problem. Varnishing the deck will keep me busy for a week (24hrs at least between coats (cold at the moment) - first sealer coat done this arvo. Might start making some moulds for the deck vents, - going to experiment with modelling clay (imprinted and waxed) for the female moulds.

    Will hopefully look better with the deck varnished Rick, just stained and basic paint at the moment. More 'stuff' to go on yet.

Just having a play with moulding some deck vents. I used JOVI air dry modelling clay and made impressions with a cyano hardened mould on a stick (pic) Baked it in the oven at 100deg C for a few hours and left it there overnight, after turning the heat off. Today I used separating wax inside the moulds, filled them with polyester resin, and warmed them in the oven to set them quicker (too cold today)

Once well set, I easily flicked them out with a hobby knife. A few were a good shape, but they all need to be sanded to shape anyhow (oversized), Worked really well for a first experiment, and with more care, pretty accurate moulding of small parts could be done (vents etc -ie half and half)

Vents now sanded, sealed and chrome painted (1st coat) They haven't come out too badly considering the crude moulding method. I've also made a different vent and a clay mould for the bow roller to be resin cast later, (both have been baked like the vents.) I think this clay is my new favourite moulding material, as when it's dry, it can be sanded or painted with anything, and used as is, ( even resin coated for more strength) or as another female mould master. About $11 a 1.1lb block.

The vents have 3mm screws cyano'd into drilled holes in the bottoms, so they can be bolted on later, and be removable for re-painting.

    It's definitely a problem getting a chrome finish Stephen, especially with paint, as it dulls if you touch it or spray clear on it. You could get plastics etc chrome plated, but the cost would be astronomical for a small item. There are a few processes, (actual chroming, vacuum sprayed metallic vapour etc) but they are multi step processes which involve labour and material costs at every step, so not really for tiny jobs. Chromed parts in kits are obviously mass produced, so the cost would be reduced. There is also vacuum applied thin foil, but it's only for flat surfaces.

    I think paint is the only option for modellers, unless you have money to burn, and don't mind waiting for months. The paint always looks like stainless after a while, which is a shame. I found if you handle it with a soft cloth, and don't touch it with your fingers, it lasts longer, as the sweat on some peoples' fingers may be slightly acidic, and react with the aluminium particles in the paint, (an old saying in engineering was that some people had 'rusty fingers' as any metal they touched showed their finger marks, while other people didn't have that effect. I've seen it myself , especially on machined surfaces, - you can even see their finger prints.

    I've made these removable for the inevitable future touch-ups.

    Thanks JB 👍
    I'll look out for that.
    Last year I tried an EXPENSIVE €€€ two part system, paint plus activator 🙄, intended for the plastic bodies of cars and buggies.
    Came out looking more like Hammerite textured 'non-slip' grey ☹️
    Cheers, Doug 😎
