You will find several sources for producing parts directly. Most are still too expensive to be practical. Prices are coming down though. Bill Jepson Sent via DROID on Verizon Wireless -----Original message----- From: Charlie England To: Rotary motors in aircraft Sent: Thu, May 5, 2011 18:53:46 GMT+00:00 Subject: [FlyRotary] 'open source' parts I'm excited to see all the activity on the accessory cover/adapter plate, & don't want to divert any attention. But Ed's post several days ago describing how he made his intake manifold triggered a thought that might need to go on the shelf for next action. The original idea that started all this was an intake manifold. My intent is to use a very simple manifold similar to Tracy's Otter manifold, but for those who need a more complex layout, what about this: If Jarrett, or anyone else on here, has access to one of the new '3D printers', doing a manifold should be a piece of cake for anyone with CAD skills (it ain't me...). Apparently, there are 3D printers that can use all manner of materials now. I wonder if you could 'grow' an aluminum or other light/strong/chemical resistant manifold directly in the printer. Something similar to the plastic coiled tube manifolds on new V8's comes to mind. OK, back under my rock....
