  1. Carpal tunnel - Well Chuck, I agree that this hobby might cause stuff like that. With the pressure we put on x-acto knives, filing, sawing, sanding....I have avoided it so far but I do feel soreness alot. Get well soon. I love following your builds.
  2. Oh Craig - that made me laugh. So you know! Heavily invested parts have gone to the trash bin over the years I have been using that lathe, due to that simple mistake and some more also, leaving a slobbering upset modeler to start over again!
  3. Ok the "intermediate rear crankcase": Similar to the intermediate stage supercharger section already described, this piece started out as a lathe turning, and then a bunch of plastic add-ons. I don't have any early-on pictures as they are so similar to what I already described. But here are some pics of the basically finished part: The large white flat area is where the "rear crankcase" will be mounted. The round white flats are for mounting of the aux stage air exit ducts. Wahoo! And attached to the intermed
  4. Chuck - as a great fan of gear and wheel well work, I offer my congratulations for a fine effort. I would have thought this kit and its tooling were designed and manufactured from computer modelling software. Which would have better assured great fit. I guess not!
  5. And now I get to show you the biggest folly I have committed yet on the R-2800 project - the carburetor. Why did I spend two weeks on a component that is going to be practically unseen? Well - part of the reason is that when I finish this engine, I intend to display it on it's own for a while, as I do other things for the Corsair like the cockpit or the wings, or the cowl. And partly because R-2800's had big bad-a__ carburetors, and it would just be neat to do one. Pretty weak.... The R-2800 had many variations, and part of those variations were the carburetor. "A" and "B" ser
  6. I decided to do the back sections of the engine at this time. I am not sure I have seen anyone model these details, because they are normally hidden. Not so for this model (I hope) - as the engine accessory compartment is going to be openable if I can pull it off. Boy, there are untold variations of the R-2800 even if you ignore the modernized "C" versions. The Corsair had a "B" version which looks very similar to the "A" version which was the original. R-2800's had a single stage two speed supercharger as standard. I think most R-2800 equipped aircraft had this. The Thunde
  7. Wow Chuck - you got skills. This Tempest is going to be bad ass!
  8. All R-2800's are attached to the airplane via a truss supported ring, and six vibration absorbing "Lord" mounts. The Corsair is no exception. Here is the Vought/Sikorsky drawing of the engine mount for the F4U-1 and 1A: I have made the ring; the truss behind it will come later, maybe much later. And that only if all continues to go well with my plan to have an openable engine compartment aft of the cowl flaps. That is not certain at this point. You may notice in the picture above that there are six mounting points on the ring - four above the horizontal centerline
  9. Exhaust stacks are basically finished except final top coat of paint. That will be down the road a bit. Here: While the stacks are not perfect, they are better than what I expected. They are only temp installed onto the engine, and every time I take them off and put them back on, the orientation of the six scarfed ends seems to change a bit. You got it Craig. Not sure, but I highly suspect copper or brass tubing would have been stiffer. Even what I used (annealed aluminum and silver solder) was pretty stif
  10. Work progresses on the exhaust stacks. Or manifolds, or pipes, or as Vought called them "collectors". I have a tiger by the tail with these parts, as expected. But I have some pretty decent results that I am kind of excited about. The locating fixture I showed last post has worked quite well. I can attach it to the front of the fuselage with masking tape, and I can leave the engine the heck alone so I don't break it. Here it is with alot more parts: The fixture's port locations are pretty close to the ports on the back of the engine's cyli
  11. Well let me modify my statement about the Mustang by limiting it to the category of prop-driven aircraft. When it comes to jets, well Katie bar the door! Some of the relatively recent Soviet jets are high on my list of sex appeal. The Sabre - an interesting pick but a good one. It's beautiful. And, coincidentally or not, it was created by North American the same producer of the Mustang. And one can see the family resemblances. Looks to me like a combination of a P-51 and a ME-262 and historically that is not far from the truth. Bombers - Maybe the North American Aviation des
  12. I am not sure I have ever heard anyone suggest that the CH-47 Chinook is a "good looking" aircraft. Unless I extended your observation too far! Now the B-17, there is a good looking aircraft in an ancient sort of way. The D-model Mustang? Perhaps the best looking aircraft of all time - I am one of many who think that.
  13. NZ??? Can I move there? I understand there is practically no covid there..... and I looove big glaciated mountains. Chinook? What is your experience with the Chinook? When I graduated engineering school (1974) I went to work in Ridley Park Pennsylvania, USA at the Boeing Vertol Helicopter plant, which at the time was churning out CH-47C's. I started out in liaison engineering right in the plant, where I became very familiar with the Chinook and also the Ch-46 Sea Knight, which was ending its production run. Later I transferred into design engineering and spent time on the tr
  14. I have quit stalling and have begun work on the exhaust stacks. Lots of trepidation, but geez - it's a model; it's supposed to be fun. My plan is to use a combination of .125 inch diameter aluminum tube and also .125 inch diameter solder. If perfectly to scale the diameters would be about .14 inch. But I could not find material that size that would suit this application. I will use the solder where I can because it is easier to bend and form. The aluminum tube will be used for the lower portions of the stacks where they exit the fuselage and the ends are exposed. The stacks
  15. Chuck - just happened onto this build (because I like the Typhoon/Tempest airplanes). Just effin' cool what you are doing. Following.
