    I realise that this is not the right spot, but

    It worked! Good to meet you this afternoon, HG, and I hope that the rest of your epic trip goes well. Jon
  2. Looking excellent, Steve. Coming together nicely. Real life always conspires to complicate things, doesn't it? I haven't been able to attend any Breighton events this summer due to other commitments (mainly work shifts!), and can't go this weekend for the same reason, but I'm 'booked in' to give a talk on 22 Sep prior to the helicopter fly-in and might have an article or two published in forthcoming club magazines. Watch this space... Jon

    Scratchbuilt 1/144 Avro Bison 1A

    I've managed to snatch a very few more minutes to fettle tiny bits of plastic, and this is where I'm at: I've started to make the radiator area under the nose by simply boxing it in with plastic card, then I've used some of my home-brew gloop to start to fill the recesses. That should allow it to be sanded to shape fairly easily - I hope. The noe itself has been built up with plastic card, but it still need a front piece to get it to the right (okay, right-ish) length. I've also cut out the tailplane piece, sanded the leading and trailing edges and started to add some fine rib tapes. I think my plan for the wheels should work out okay; here's one after being slightly cleaned up but obviously not yet painted: Right! Back to real life again... Jon

    Thanks for the encouraging words, Phoenix. I'm not sure how many "really useful ideas" you're likely to pick up; it's usually the other way round! Also, I keep saying it but progress will be slow - one day I'll look back with astonishment at just how busy life was in my forties! Jon

    Scratchbuilt 1/144 Avro Bison 1A

    Yep, that's what initially caught me out: the plan that I used shows the separate upper wing and portholes. N154 was a prototype of the Bison 1A with the upper wing gap, after which the portholes were deleted. I think that the photo above would have been taken during testing at Martlesham Heath, as it clearly shows the auxiliary fins mounted below the tailplanes; these were later replaced by a fin extension that appeared on the operational aircraft. As was so often the case with 1920s military aircraft, the clearest photos tend to have been taken during testing when all sorts of changes were made to airframes in short periods of time. Anyway, nice pic - thanks. Jon
  6. !!!!!!!! !!! ! Wow... Very impressive. Keep it up, Phoenix! Jon

    Very slow progress, I'm afraid, 'cos real life doesn't have a PAUSE button. Upper wing is more or less done; the lower wing still needs its ailerons separating. It will be cut into two separate wings and butt-jointed to the fuselage...eventually: The fuselage has been closed - or, at least, the observers' cabin has - but it's very rough at the moment, emphasised by close-in photos. I'm pondering how to create the nose section, so I've made a central former and I expect to build it up with plastic card and sand/carve it to shape. The cockpit top will be tricky and I haven't worked that bit out yet: I thought I'd have an early bash at the wheels while the cement cured on the fuselage. I found a small bag of assorted O-rings which contained two that are about the right size. Next I cut some discs using my cheapo hole punch, then pushed their centres with a ballpoint pen to get a slightly conical effect: I may have to stack some discs to get them to sit correctly. Here's a rough trial run (apologies for the dodgy pic): Now back to that real life thingy. Jon

    Anyone heard of intarsia

    Correct Steve, it isn't intarsia, just a form of scrollwork made using plywood. There is a gap of about 6mm between the front face with the design and the solid dark-stained backing piece.

    Anyone heard of intarsia

    Sorry kp, I should have said this in my previous post: I like your work, especially the rose which is a great combination of stacked fretwork and relief carving. I presume you used woodstain? It looks very effective. Creating it using a hand fretsaw rather than a mechanical scroll saw is impressive! Do you have any more pieces to show us? Jonesy - that made me smile! I'm a Yorkshireman, but the rest is my business... Beardie, Steve: traditionally, intarsia is a technique whereby individual pieces of wood are cut out and shaped to give a degree of 3D relief effect, then the pieces are reassembled to create an image much in the style of a jigsaw. The 'pro' way to do it is to use different woods to create different colour effects, but I've only ever used woodstain on differing thicknesses of white pine. Here's the barn owl that I made a few years ago using this technique: After cutting each piece using a scroll saw, I sanded them by hand to get the rounded edges with the grain showing like contour lines. The feet were shaped in the same way. I've since bought a Dremel to speed up the sanding process and limit the damage to my fingers and thumbs! The pieces were stained, waxed and reassembled onto a plywood backing piece. A scroll saw is just a quicker (and easier!) way of cutting fretwork than using the traditional fretsaw, though I've seen fretwork cut with a handsaw that is astonishingly complex. Here's a scroll-sawn piece that I made for my wife: Jon.

    Heard of it - yup, I went out and bought myself a scroll saw specifically because it intrigued me and I wanted to have a go! I haven't made an intarsia piece for quite a while now, but I'll see if I can post a pic of the lifesize barn owl that I created. Wait, out... Jon

    Scratchbuilt 1/144 Avro Bison 1A

    First stab at the upper wing: Photos show that the ribs were not pronounced but rib tapes were clearly visible, so I've tried to replicate this by cunning application of primer between 2.5mm strips of Tamiya tape, followed by another primer coat after removing the tape strips. The tank is made from plasticard and the primer has highlighted that the top is flat, so a bit more sanding needed to round it off before breather pipes are added. The ailerons will be separated and have their forward (ie hinge) edges gently sanded. That will pretty much be it - I really don't want to get bogged down here. Lower wings probably next while the fuselage is still a work-in-progress, though trying to scratchbuild some wheels and tyres is also on the agenda. Jon

    Righto, I think I've worked it out. Prototype and some early production Bison IA aircraft had the portholes. Putnam states that "late production aircraft had the centre-section gap further increased but were without the undercarriage arrestor claws and circular portholes forward." These aircraft seem to have been known as the Bison II. The production upper wing slso had a cutout at the rear of the centre section. This is pretty much the mod state that I intend to build, following a photograph on p226 of Putnam's excellent 'British Flight Testing' by Tim Mason. To that end the carefully-drilled portholes have been blocked with tiny plastic discs cut using a cheap-as-chips disc cutter bought from a high-street home goods store and secured with a drop of my finest homebrewed gloop: Upper wing next.

    Thanks, Marklo. The idea behind scratchbuilding in 1/144 was that I wouldn't feel obliged to add much detail and would therefore be able to progress quickly. Yeah, right; no plan survives first contact, etc. Anyway, go for it with your plan - the Gamecock is a great-looking aircraft but the engine won't be easy! Jon

    As a bit of background, there were fundamentally two different Bison airframe layouts. The Bison 1 had a small fin and the upper wings were attached to the top of the fuselage. Most of them seemed to have been fitted with two circular portholes ahead of the large rectangular fuselage windows: The improved Bison 1a had a fin extension, an upper wing that was mounted above the fuselage with a bit of associated struttery and, as far as I can tell from photos, no cicular portholes: This is the version that I am intending to create, but... You know that old 'check your references' manta? The one that has caught me out so often before and which I regularly wish I'd remembered? Anyway, I realised late last night that I'd merrily followed the 'Bison 1a' side view that I'd downloaded: ...and put a pair of portholes in each fuselage side. Golly jings, I thought; that was jolly careless. (Okay, I was less polite.) I'd really like to make a 1a, so I will have to correct my carefully-drilled portholes. Grrr. Before I do, though, I need to do some more research to confirm that the plans are inaccurate. Jon

    Yup! Just been trying to make the wing rib effect. Aargh! Hmmm, perhaps... the fuselage isn't quite such a straightforward shape, but I love the 'function over form' looks. Probably more by learning what NOT to do, in fairness! Hopefully more tomorrow, though I have a Moggie Traveller to service in among the domestic chores - how random is that? Jon
