  1. Thank's druxey, I am happy with my results and know I can make more as needed. Here is the one for my " John Cudahy " all colored up and with a ruler.
  2. Awhile back I decided I wanted to replace the left handed propeller on my " John Cudahy " project with a right handed prop. So I carved a four blade right hand propeller. Then I thought I might as well see if I could cast some extras. Starting with some vulcanizing rubber and a round mold frame I added a bottom layer of red vulcanizing rubber. I than pressed the master pattern into the rubber as deep as I could and added rubber under the blades. To create a parting line around the edge of all four blades.The prop and rubber was than cooked to harden it up. Once the bottom was done I used a liquid room temp vulcanizing rubber and poured it over the bottom half. It needed several days to set up at which time I cut the softer upper layer in half and removed the master pattern. I had included four position pegs in the mold so it can only be reassembled one way. To mount the mold in the centrifugal I cut two plywood disks just slightly larger than the mold. one for the back side and one with a hole that lined up with the fill hole in the mold. using four quick clamps the mold was mounted in the centrifugal's cradle and lined up with the crucible. In the melt pot I heated up some Cerro Cast alloy to use in the mold. When things were ready I spooned in some liquid cerro cast into the crucible and pulled the pin.Stood back and let it spin. The first few try's showed a couple of kinks which were taken care of.I ended up making four propellers which I can use for other projects. Using some files I cleaned up the flash and did a little more shaping. Once I was happy with it I sandblasted the whole propeller. This was my first time trying to cast a propeller and after tweeking the mold a little I am getting good throws each time.
  3. John & Patrick, I still have some odds and ends to do than I can move topside again. Thanks for checkin things out. Michael, I do have a couple of LEd's down there that might help in seeing some detail. Thanks for stopping by.
  4. Hello John, Welcome to MSW I live up the Willapa Valley about an hour drive from you. Not wet here at the moment.
  5. Gary, I used Cerro Cast A low temp alloy in vulcanized rubber molds. Cleaned up with files and sandblasted. Finished with black india ink. You can see more on posts 38-40. Glad you like my little engine.
  6. Thanks everyone for the "likes" Learner a separate build log for the engine would be a lesson in what not to do. So many things did not go the way they should but I am still glad I foraged ahead and built it. John, Thanks for stopping by I have been watching your tug as well, great job.
  7. Rob, Here is a model of a pinky that I built many years ago. It's dirty and needs to be rerigged. It was one of my very early scratch builds. I copied the plans out of the book: American Sailing Ships their plans and history by Charles Davis.
  8. John, One can almost smell the hot oil and steam, glad you like my little engine. Patrick,Nothing was/is easy with this little bugger but I am having fun with it.
  9. Gary, glad you like my engine it's been a interesting build so far. Michael, Some of it will get painted ,some will stay a brass look. Guess when I have It all together I will than decide what gets painted and what gets left alone.
  10. Just a teaser to show I have been working on my project. It's far from being done and there are a lot of temp pins holding things together. Once I have all the parts made than I will do the final assembly.
  11. John, Patrick Thanks for stopping by Roger, I plan on including a jacking gear on engine.
  12. Well I spent a little time down in the engineering space and have put together a little work bench.
  13. Well, It's been awhile since I posted a update. I have not gotten a lot done is why Have been working on the boat davits but nothing to show yet. Did manage to put together the spot light mounted on the wheel house roof. First picture is of spotlight parts and the inside wheelhouse control. This is how the spotlight looks like on the cabin top. sorry for the dark picture.
