    My latest engine build

    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

    Fantastic piece of work Terry. Looks like a great deal of high quality work, and with nine of everthing!. Good luck with the repair and with solving the fueling issue.

    Terry,

    Amazing! I'm always impressed anyone has the time, much less the patience and skill, to do something like that. I know I could never do it. Beautiful work!

    Regards,
    Ray L.

    Very nice Terry,
    I have been following your build over at HMEM.
    I saw a YouTube video of that engine built by anther gentleman around 3 or 4 years ago and that is what got me to pursue this amazing hobby.
    Thanks for the inspiration,
    Gerry

    Hi Terry

    Holy Crap ! That is some beautiful work.

    I will be following along with the final steps and can't wait to see the video of it running.

    I learned a new term recently, "Machine Porn". I am pretty sure this is it.

    Beautiful! This, and Steve Huck's "Little Demon V8" on my must do list (modeled, not programmed yet), behind finishing my ATC. Maybe by 2020.....

    Nice... I started mine before I had CNC, and need to get back to it. I live only about 30min from Lee, and picked up my plans in person. I'm slowly putting mine in Solidworks and will do some design changes along the way, particularly piston design, but the visible one is cylinder heads - In real radials, the finning around the exhaust is much bigger than the intake for obvious reasons, so I will change that a bit... Maybe not so ambitious as "Swede" , but maybe a bit more like the real thing. Might be fun to turn the fuel distributor into a supercharger too... Yours certainly looks great...
