  1. So I cut half-depth slots on the keel and bulkheads and the result seems OK. Certainly the bottom of the hull went on without much in the way of unevenness. The double curves (bow and stern) of the hull bottom gave me less trouble than I thought - the trick seemed to be "glue one end onto place and then - once dry - glue and clamp the other". The real problem was always the curved pieces on the edge of the deck. It took me numerous trials and broken sticks before I got something that looked reasonable. I tried soaking the sticks and rubber-banding them into place to dry but they often wound up cracked or not having sufficient curves (couldn't get the rubber bands tight enough) or curves that matched their neighbors. I finally settled for mass-producing curved sticks (as in "wrapped around a pipe") and using those that survived and touched where they fitted. The hardest part was the edges of the bow, which had acute angles. It took me three months and dozens of cracked sticks to get the effect I wanted. Even so I had to sand the angles of the top of the A bulkhead a bit to reduce the angle. But in the end I achieved something that might do the job. Hopefully with a bit of sanding it'll look creditable.
  2. I thought this time I'd try something which had a chance of perfection. From the plans BB looks fairly straightforward (I'm using Garry Findlay's plans) and my previous project has taught me some patience and the fact that redoing work can pay off. I needed to stock up on my stick collection, so I went to my usual site, grabbed the page with large sticks and ordered 500. They seemed a bit expensive this time and I was taken aback when they arrived to see they were larger than the previous bunch - real tongue depressors. So now I have 3 sizes. However this turned out to be an unexpected benefit as they are just large enough to build the bulkheads. Since my reason for using Popsicle sticks is to increase difficulty, I'm happy to abandon plywood bulkheads for this project. BB is nearly 3' long and the width of the large sticks also makes it reasonable to build deck shear, chine and keel with some chance of getting a good result. There is one complexity to this model which is going to give me grief - the deck edge is curved and obviously a double-curve of varying degrees stem to stern. I've noted previously that Popsicle sticks don't like curves and double curves especially. (In fact I have no idea how real model makers do double curves, apart from carving them from solid blocks. Maybe balsa wood is more forgiving with double-bending - anyone care to advise?) The brief assembly instruction are not helpful - they assume the modeller knows what he is doing. After numerous failed experiments and cracked sticks I've begun mass-producing (well, two at a time because that's all the pipes I have lying around) curves for the fore-part where the hull curve is fairly straight and I've kicked the problem of the tighter curves near the cockpit into touch at the moment. But I've run into a problem and I'd like advice. Garry's plan appears to show that, although the positions of the bulkheads are marked on the keel, there are no positioning slots cut in it. All the slots are only cut into the bulkheads and the depth of cut in most (C - E etc) appears to cut the bulkhead in half (at the bottom anyway). This seems to me to weaken the frame and possibly introduce distortions. I have enough trouble with self-induced distortion without planned ones. The instructions are silent. Can anyone suggestion why someone as obviously competent as Garry would do this, and should I follow? It is more of an intellectual problem because I know how to solve it - cut half-depth slots in both the keel and bulkheads. Unless someone can tell me why I should follow the plans.
  3. Thank you all for your kind words, likes and suggestions. I'll have a further poke around my local model shop for things I never knew existed.
  4. Finished at last. I'm sick of it! It looks OK in the photos but the finish is terrible up close, and I gave up trying to rescue it. The white paint is uneven probably because the deck is uneven from the rain damage. Popsicle construction is not suited to large expanses such as the deck. The hand painting (blue) doesn't come out well and the pinstripes are awful. I used sticky tape for masking and the uneven white paint cause the blue to leak under the tape. So various corrections tried with sandpaper and white paint and the corrections with blue paint. And so on - I'll never do pinstripes again! The paper labels look like paper labels. As noted I spent weeks building the engine cover, but I think it looks better without it - I'm reasonably pleased with the engine and (in the absence of the cover) it draws the eye away from the numerous decorative defects. The irony is that the plans didn't have an engine cover at all and I had to make it from photos. Never mind! It is the build that is the important thing and I have learned a lot (mostly what not to do).
  5. After a couple of weeks of careful drying it didn't look so bad. While the glue was still unstuck the wood sticks shrunk back to normal size, albeit with some pieces still being slightly curved. It took two months to rescue the hull, but its not too bad. The deck looks OK - you can see from the uneven sanding that some curvature needed to be smoothed down. The underside isn't so good because "walls" encouraged what were effectively "pressure ridges" and so it is more uneven. I only had to replace a couple of pieces, though. But because of the uneven surfaces the areas of power sanding were limited. In some places the wood is now paper-thin; in a couple of places I've gone right through. i'll see what things look like after a couple of coats of paint - that should show up areas that need more sanding or filling. But I haven't been idle while waiting for various bits of hull to dry; I've tackled the really hard stuff - the superstructure - which has lots of curves. As I've mentioned before, Popsicle sticks and tight curves (especially double curves) don't play well together. It took me a month to complete the cockpit and tail. Because it is often necessary to glue a single piece, then wait for it to at least bind before gluing the next piece its a time-consuming process. There are 39 separate pieces go to make this up, and a good half-dozen sticks were broken in the process. It took me another month to build the engine cover - this time (although there are a lot of pieces) the delay was more bending the nose and roof pieces to the correct curves. I broke a good dozen sticks before I got it right. Mind you some double curves are easy, if time-consuming. The top of the nose is 14 individual pieces glued in top on each other and sanded into a curve. Its nearly ready for final painting and assembly - if the painting shows everything is smooth enough!
  6. Disaster! The hull was complete with only a couple of coats of paint needed to finish. I left it out in the sun to bake, forgot it and it rained. The problem was not so much that the glue dissolved; it was that the wood expanded and - in the tight alignments - warped. My beautiful smooth surfaces are all wrinkly. It it salvageable? Dunno - the warping is a real problem. I'll dry it out and see.
  7. The hull has been the real nightmare. The design has internal curves, acute angles and sharp obtuse angles. Some of the sticks require double curves and keeping these the same curves (where they must butt up against each other) was difficult. But the major problem I had was that my clamps often were too short to keep planks in place. Eventually I thought CA glue might have solved this problem but the quantities would have been prohibitive. So I pressed on.I had to sand and fill the tunnels before they were complete as my finishing sander wouldn't fit once both sides were on: with sanding: But now I'm nearly there with the hull - a couple of difficult pieces to add. Much last minute gluing and filling and sanding, but its just about time to put a single spray paint coat on to see where the defects really are.
  8. Thanks Piet. The purpose of this build was to try out the plywood frames as enablers of precision and symmetry. Thus I chose what I thought would be a simple model to prove the enabler worked. Some simple model - it is a nightmare with Popsicle sticks! The first problem is there is no keel, so lining up the bulkheads correctly was my first challenge. By sitting them on the plan and propping them in place while the glue on the stringers dried I managed to get something I was not too ashamed of. For the deck build - on a properly-built model one would stick the plan templates to the sheets of balsa and excellence is guaranteed. But with this model the deck is so wide (12" at the widest point) that ,while I could lay the cut-out deck plan on top of the roughly-shaped deck and mark the final shape, the cutting had to be done with the deck upside-down (unmarked) because of all the extra sticks (joining pieces, frames) would get in the way of the saw table if I did the cutting topside up. This is what I mean. So the shaping involved a lot of guesswork. In the end it doesn't look too bad from a distance. But I don't guarantee symmetry.
  9. In my previous build (Riva Aquarama) I said I would never again make the bulkheads from popsicle sticks. I've proved it can be done but (as a commentator pointed out) the unevenness and asymmetry of my model may be due to uneven or asymmetrical frames. So for my next build (hydroplane - no motor) I decided to use plywood instead for these. This is what a well-made model looks like. I found precision cutting the plywood was much easier than shaping the Popsicle frames and I thought there was a reasonable chance that this model might be tidier than the previous two. The plan has stringers running fore and aft on the deck side. My first deviation from the plan was to cut notches at the bottom of the bulkheads for stringers running the full length again - the stringers (top and bottom) were to hold the bulkheads in position so the numerous Popsicle sticks would be in the right place. The above photo shows the start of the deck stringers, with an extra stick at the bow to give a surface for the sticks to glue to (a necessary addition since I'm not using a single sheet for the decking).
  10. Finished - except for the steering wheel. I can't find a (cheap) toy of the appropriate size to steal its wheel. I've ordered a wheel thru my local hobby shop but they say - on past experience - it will be weeks, months or never before it arrives. Its been a month. Riva might vaguely recognize the hull but never the fittings. It was the best I could do and I'm reasonably pleased with the result. (Although I've recently noticed the hull is twisted slightly stem to stern). The dashboard bears no relation to the real thing. I had several attempts, drilling holes with bigger and bigger bits but they all ended up splitting - even when I made ply with a second layer glued on with grain at right angles. Eventually I realised splitting this medium was inevitable so a complex dashboard was out of the question. Hopefully the splits are concealed by the wood stain. The fo'c'sle ventilators should be flat and circular. My attempts at those were obviously going to look horrible so I settled for something simple and attractive. The mooring rope guides could be better, but I'm reasonably happy with the stern access rails.
