I went to a model contest in Austin this morning. I got a Renaissance 1/24 Ford Mk IV, Protar 1/9 Honda RC166 (the 6cyl racing bike), and a Gerstner tool box. It could use a little cleanup, but I've seen them in worse shape for more money. It will hold tools for my Sherline lathe and mill. I'll see if I can get pics later today.
I have a small vacuum former that you can borrow, if you want. You could make a master and pull one over it, or you could make that hard frame for the bottom and blow mold one. That's how a lit of the real bubble tops were made. My vacuum former has PVC pipe fittings where the vacuum cleaner hooks to it. I could send a hard extension that I use on my Shop Vac or I could change it to something better for blow molding. I'm thinking of a PVC extension with a schraeder valve so you could use a regulated air/CO2/Nitrogen tank and figure out the right amount of pressure to use. I had never thought of blow molding a model bubble top until I read your post. I may have to try it for an idea of my own.
The Plano 8600 is long enough for Evergreen strip styrene in the sleeve it's sold in. I had plenty of that, plus a bunch of individual tubes of super glue and my ancient glass bottle of Zip Kicker... And lots of other stuff. I used the strip for improving the interior of a Johan Mercedes, a new reveal on a modified Duesenberg, and rebuilding trim on the vinyl top of a Duesnberg town car. FYI- Tamiya's empty glass paint jars have a soft plastic gasket that is not affected by MEK, if you use that in scratch building.
I have 3 of the AMT/MPC 1928 "Gangbusters" Lincolns. They have an entire sprue of gangsters and parts; two figures plus weapons. IIRC, it's the Tommy gun, shotgun, revolver, 1911 pistol, 2 "pineapple" grenades, and even some deal for smacking people around. I have no use for this stuff. Got anything cool to trade, like street rods, lead sleds, or pre-war coachbuilt classics?
Wow. For $97, I'd buy one and make it look like what I would want in real life. I'm a huge fan of the Lincoln Mk V. ...but that body style was 1977-1979. That's such a nice looking car. It would only get a mild cleanup. Maybe do something different with the lights on the trunk lid and get rid of the bumper overriders. Spray on some show car quality candy brandywine.
The last time I used it "in anger" was 10 years ago. It's a Plano 8600 tackle box that opens like a clam shell on top; two symmetrical sections of small compartments, plus a big open section below. I took it to Afghanistan in 2005. It held a surprising amount of supplies and tools. (There was no quick trip to the local hobby shop over there). I would say that it would hold everything you need for a 1/24~1/25 car project, including spray paint and the car, if packaged carefully. I did fill it up a couple of months ago for an out of town trip, but ended up not opening it. Inside was a long term project, a 1/12 show rod very heavily influenced by Dan Woods' "Ice Truck". The body of that car is pretty small, even in 1/12.
Some people are willing to pay $70 for a 1/24 Tamiya car. Some people are not. Revell caters to people who will pay $27. Maybe not the same car, but a few have been done by both companies. It's not good or bad, it's just the way things are. Those less expensive kits can be a way to get someone into the hobby. Aunt Cindy might get Johnny a Corvette model for Christmas, but she is much less likely to get him a $300 B-17 kit. If the '29 roadster kit had an MSRP of $70, I'm sure it would be closer to what Tamiya offers. I'm glad it doesn't cost that much. Mine is not getting the Nailhead, so the incorrect port spacing means nothing to me.
