Thanks for sharing the vacuum forming setup. Very impressive what you have done.

Hi guys, I thought I would post a few more pics to hopefully clarify some of my narrative. These shots actually are of my new H-34 project but show what I think is a good approach to using balsa blocks to make the forms. I also thought I should have stated in my first post that the H-19 is a "stand off" scale project in 1/11 scale and I couldn't come up with a gearbox for the raised tail that would fit this size. I'm using the RCA/Smartmodel gearbox in my H-34 but it's too big for the H-19.

Hi again, these shots show what the form looks after vacuum forming even though they are also of my H-34 project. After forming, but before removing the form from the plastic, I mark the plastic to guide cutting the shape out. Then the fun begins in fitting and gluing the pieces together. Let me know if there are any questions and I'll try to explain. Bob

Hi and thanks for the compliments. I'd like to go to some scale heli meets some day but I'd be too intimidated to show my relatively crude vacuum formed models. Bob

Hello to all you scale fans. I'm posting these photos for several people I've heard from about building an H-19. These photos are from a 70's book illustrated by John Batchelor who was an excellent artist. I hope this helps anyone needing info on the H-19. I should mention that they are pages torn out of the book and therefore there's a seam.

Hi to all you H-19 fans. I took a lot of photos of two H-19 in museums while on vacation and I'm trying something new by posting them on Pinterest so everyone can see them in full resolution and use them for scale reference. The first one is from the Evergreen Museum in McMinnville, Oregon which is a world class facility and home to the Spruce Goose. Let me know how this works and what you think of it.

This second group of photos is from a Canadian Museum of Flight in Langley, British Columbia. This H-19 sits outside and is a little weather beaten but they say they hope to restore it some day.

This third group of photos is of an H-19 transmission and rotor head that sit inside at the Canadian museum. You don't often get to see this view.

I also want to tell everyone who has asked me about buying a set of shells for the H-19 that I will get back to it and they will be available. I've gotten busy with the H-34 project and trying to get it finalized and ready to produce some for the people who requested them. It'll probably be late winter by the time I make the improved forms for the H-19 and try to produce some for sale. So, please be patient.

I spent some time flying in a Sikorsky H-19 Chickasaw, back in my long ago AirForce days.
Recently I bought a small vacuum forming setup just to start learning. I made a nice clear dome shaped cover for my grandsons waterproof quad. If I had seen your setup I would have built my own, and still might when I need a larger forming set up.
Your work is impressive, thanks for sharing the details, especially about the types of materials/plastics used.

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

This pic shows how the current configuration looks. The Bavarian Demon stabilizer works very well. The mechanics are Trex Nitro 600 converted to electric. The head is Chaos 600 flybarless.

In this view you can see the new wooden substructure and modifications to the Trex frames.

hello seahorse bob,
Very good job and a nice flight! I've used this vacuum system for making a windshield for my r-22. It works great. Used my oven for the heat source. Made mine almost the same way before I saw yours and they almost look identical, even the material. The biggest job as you know is making the mold. ken
