I'm close (I hope) to finishing a 9 cylinder radial engine that I've been working on for 1-1/2 years. I started a build thread on the Home Model Engine Machinist forum at:
My Hodgson 9 Radial Final Assembly - Home Model Engine Machinist
I actually started the thread pretty much after all the parts were machined and when I began final assembly. But I have included some construction photos as well. About 2/3 of this engine was machined on my PCNC series-I mill using metal I colected from a local scrap yard. I use SolidWorks 2007 for my CAD, and I ended up compiling over 250 Sprutcam programs for my mill and my 9x20 Wabeco lathe along the way. If you visit the thread you'll get to see the current saga of getting one of these beasts to run. - Terry
