Hi,
Newbie here as a result of a fringe need on one of my other projects. I have a metal lathe that I can not buy parts for. (Old and out of procuction). I need 3 backplates cast in gray iron to mount my chucks to the spindle and one as a faceplate to turn between centers. I posted previously and apparantly I said something that was not acceptable and it, I guess, was pulled. I will try again and not be as descriptive. I am looking for someone local to portland oregon that is willing to work with me in a way that is fair to both of us to produce these castings. I have been to many sources and the base of knowlege and experience here seems to be the best that I have come across yet. I have been to some of the do it yourself sites and realize that castin iron is a step above the normal requirements and is something that for 3 pieces is more than I want to invest in. Thanks to all who comment and lend their experience to my endeavor.

Hi all,
I am looking for someone in the Portland ORegon area that casts gray iron. I have a Pratt and Whitney metal lathe that has only one backplate to mount chucks to the spindle with and I need more. The lathe has a larger than common thread on the spindle that prevents me frrom buying a partially finished blank from the common suppliers. Most blanks go up to a 2inch mounting thread and mine requires a 3inch thread. I have contacted a recommended 1 off foundry and after a bunch of time getting ignored The price of three blanks was pushing the price I paid for the lathe to start with. After looking online and asking all my sources here I have pretty much decided I am going to have to do it myself. Then I landed here. This looks like my last best collection of sources and resources. In the past I was a member of portland tech shop which is a collection of Do it yourselfers that com togehter and pool machines, knowlege, time, experience and commeraderie. You paid a monthly membership fee and could use the equipment after qualifying, just like a gym membership. Anyway on the back dock there was a foundry setup and a pattern making shop. At the time it didn't strike me so I didn't seek out info on the owner/operator. Tech shop has since gone bankrupt and out of business, so I know there is someone in the area that casts. I am asking for help locating anyone in this area that would be interested in working with me in ANY capacity in regards to getting me a couple of blanks. (trade, buy, barter, help with process) Thanks in advance for all your responses and leads.

HI,
It is a Pratt and Whitney 13 30 Model B with a 3 inch 3 1/2 TPI tapered nose spindle. I didn't get any tooling with it so I am having to make anything I need. I have considered the plate and boss method and haven't ruled it out. Both menthods have their merits. I was checking out this forum to see what the availabity to casting would be. I have cut a couple of tapers (jarno 13 not Morse) for dead centers to turn between centers and some specialty boring bars. I have grown up living outside the realm of what normal people consider do-able so I have a history of trying when I probably shouldn't. I was hoping to benefit from the knowlege and graciousness of the people here. I am in the portland oregon genreal area. Again thanks to all who lend information and input.
