Ranger type yacht by Mark Pearse - 1:12 - SMALL


Recommended Posts

Hi Rick

 

The panels have timber in 2 thicknesses, & using a sharp knife I cut strips from thicknesses timber to suit the pieces: centre panels & the rails in thicker (approx 2mm), the recessed pieces that surround the centre panels are about 1.25-1.5mm thick. Then just assembled & glued as I went. I made a small 45º angle tool, to get the corner mitres for the recessed strips fairly accurate. I have 2 more panels & will photograph some of the stages. 

 

I've been using a pencil, a regular pencil with timber etc. It's hard to keep them sharp enough to mark really accurately, so I'm thinking to go back to a 2mm granite clutch pencil with a rotating sharpener....getting a pin-sharp tip will be very helpful.

Thanks all,

 

Druxey, when I was still drafting manually, I used 5H on plastic film. Nice sharp lines & no smudging. 

 

Some progress with the same area, the vertical face of the raised deck. Some further detail, in response to Rick's question. Everyone has their own method, & I have done it this way:

 

The removable side panels that sit either side of the companionway hatch have a flat centre panel with a recessed surround frame, & then rails top bottom & sides, like a mini door. I didn't chamfer the surround frame strips, just recessed them. Nice sharp knife, careful measuring & careful gluing is my approach. Important is the opti-visor, being able to see is essential.

Then sanding on paper glued to acrylic pieces.

One sanded & one not...the effect of some careful sanding is nice to see. An important part of model making indeed.

Dry fitted, with the separating frames that will be fixed to the side rails of the hatch. There will be curved members that trim the back edge of the raised deck. The bottom edge is slightly raised as the cockpit seating is laid teak, I've allowed 2mm for that.

I've realised that this work can't go further until the hull is painted. So I'll put this aside for now, I'm changing tack & will make the toe rails, gunwales & sponsons. Then paint.

 

bye for now,

Mark, the panels look excellent, particularly given your reliance on basic hand tools.

I decided the next major job is to paint the hull, & before that I have to make & position the gunwales & sponsons. In particular, the sponson line is important to the hull's appearance, & must be just right. It's mainly about the tapering gap above the sponson, between it & the gunwale. Hence the need to do both. The gunwale position will be a constant distance below the deck line but the sponson is tricky. My plan is to use brass pegs as dowels to fix the final position, put them aside & install after the hull is painted.

 

On the actual yacht, the timberwork around the cockpit is teak, varnished or unfinished; & the hull timberwork is Spotted Gum - a tough hardwood that steam bends well. On the boat they have faded somewhat so I have used some Blackbutt that I have, a length of floorboard from a building site. I ripped some strips off on a table saw & then used a well sharpened plane to bring the timber sizes down further, & then to shape them. 

 

The strip on the left is a future gunwale, about 2.5 x 4mm.

And shaped, finely sanded & one coat of shellac wiped on. I'll do some more coats later.

Below are the future sponsons, about 4 x 5.5mm.

A little more....

 

The sponsons are now shaped. Below is the method I use for holding the strips while shaping, & my tools of choice; which works for 1:12 but techniques that work at this scale obviously might be an issue for much smaller scales. The back of the sanding block is 240 grit, & I have some finer (the softness of fingers helps sand curves), also some fine steel wool.

IMG_3462copy.thumb.jpg.f37b606d896eb01292486a70328d5707.jpg

 

Here's the strips: 2x 700mm lengths of sponson, 1x 1m of gunwale (a thin coat of shellac, hence the colour).

I'm with Rick. Many thanks for that explanation about the panels (and sponsons). 

Great results on both. She'll look awesome.

Mark. I might have tried creating a shaper by grinding the required shape into an old craft blade, however your method works rather well.

Hi Keith

 

I have done something similar for a picture frame. It never occurred to be to try that for shaping these. By 'craft blade', do you mean like a blade from an Olfa style knife? as below

Mark - yes that is what I mean but old hacksaw blades are just as good. I use old blades and make sure that I have ruined the edge by rubbing on a stone. I then grind the shape into the edge opposite the blade.

  • 2 weeks later...

The current progress is towards painting the hull. Concurrent with the work below, I am working on some test panels for a hull paint - but just a little on my thinking: black shows gloss more than other colours, & as a gloss object at scale will look more real if the gloss level on the model is less than the actual...I'm going to be a bit fussy on that. 

 

The sponsons need a bit of assistance to make the curve of the hull shape, & fortunately Blackbutt respond to some heat reasonably well. My method was to scribe the hull shape on the bench, adding a bit more curve to the shape. Set up some angle brackets, clamp the middle one & heat sections (with a hot air gun) away from the middle & progressively clamp them. I suspect this isn't as good as actually making a small steam box & then clamping, partly because you haven't got much of an idea what effect the heat is having on the timber. Anyway, it worked well.

I also gave one half of the gunwale the same treatment & then put them on the hull in a temporary way. That's partly so they have somewhere to stay while retaining the curve. Looks great. The last part of the sponson near the stern droops a bit, but that can be tweaked later.

One aspect I'm not sure about, & would certainly welcome opinions: whether to paint the hull then glue the sponsons / gunwales, or glue them & then paint the hull. Painting is easier in the first case, getting the timber strips accurately positioned is easier in the second. I am leaning ever so slightly towards the latter. It would be good to get whatever opinions I can, from you all.... I'll also do a post on the in the paint section of this forum...

 

thanks in advance,

She's looking beautiful Mark

 

I prefer the glue first paint later approach as it's easier to get them positioned properly as you said and easier to glue them on. Masking tape works well and can even be placed on the later painted surface to protect it from fine detail sanding of any paint that bleeds under the tape onto the sponson

I would also go for glue first, paint later. 

 

In case of first painting and then gluing: 

If the curve doesn't fully match with your hull, you'd have the risk of it coming loose since it would be glued to the paint instead of directly on the wood. 

 

You could of course paint first, with the position of the sponsons masked (and glue them on later), but that would be difficult with the risk of having to touch up on the paint later....

Yes I agree.

 

The unpainted hull is looking beautiful. Pity to paint it really.

Onwards... I have glued both gunwales to the hull, & the port side sponson. The timber has about 4 coats of brown-orange shellac, finished with steel wool. I will give them another go before painting.

 

The plywood deck had a prominent change in colour of the veneers at the height the top edge needed to be, below the deck line.

IMG_3535copy.thumb.jpg.c01ead7655b5ffb4b3712726fde799bb.jpg

 

For the gluing, I had swallowed my pride & decided on CA glue, as I didn't want to put any mechanical fixings through the timber as I couldn't see a good way to hide them, & using CA did allow just enough time to make sure the strips were accurately placed. The sponson-gunwale relationship is critical to the appearance, so errors were just not on. The port side sponson went on quite easily yesterday, & I had a go at the starboard side, which didn't go well... I was fighting some twist in the timber & was struggling to get a good bond with the load of that twist. I've learned that with CA, you need to get a good bond first time if you can, & the struggle had gone on too long. So, I pulled it off & set up the heat bending frame with an inbuilt twist....It's not much twist, but these native hardwoods have strong opinions & this one needed more encouragement.

IMG_3537copy.thumb.jpg.fce5ae0e44fe4f7f32f53956c60bb849.jpg

 

You can see from the pencil line on the bench that the brackets were repositioned & the upper legs bent. So the sponson is in the same basic curve ....just with some twist. It's now clamped, heated (heat gun) & on the clamps for for a day. Tomorrow, I'll sand off the dried CA glue from both surfaces (vip in my experience) & try again.
