factory 487 #2 Posted November 22, 2014 Another cutaway O&R engine, this isn't mine, it was on ebay a few years ago. I wonder how many they made. David 2 pmackellow and diggerjames reacted to this Share this post Link to post Share on other sites

Wallfish 698 #4 Posted November 23, 2014 The one I posted is not mine either, just a web pic but definitely thought about doing one of these myself. Shouldn't be too hard using a band saw and a Dremel cutoff tool. Share this post Link to post Share on other sites

CNew 404 #6 Posted February 25, 2019 This would be a neat find, an O&R engine cut-away display. https://photobucket.com/gallery/user/Hodakaguy/media/bWVkaWFJZDo5OTcxOTI0/?ref= Share this post Link to post Share on other sites
factory 487 #7 Posted February 25, 2019 (edited) I can just about make out that it says 1970's on the brass plaque, which is wrong as the engine actually appears to be a 1960's engine from the style of starter fitted, the black cylinder cooling shield & no extra fins on the crankcase. I've been keeping all my damaged engine parts for possible reuse to make a similar cut-away engine, but I wouldn't cut-away the hard to find parts such as the air filter & muffler.

CNew 404 #8 Posted February 25, 2019 David, That would be really cool. I don’t have enough scrap parts or engines to do that yet but a cut-away engine display would be a fun project. Share this post Link to post Share on other sites
factory 487 #9 Posted March 8, 2019 This is from one of the brochures I have, almost exactly the same apart from having a cutaway gearbox too. David 1 CNew reacted to this Share this post Link to post Share on other sites
factory 487 #10 Posted March 12, 2019 I have merged the two O&R Cut-away Engine threads & edited the title to add the engine type (3/4HP). David 1 CNew reacted to this Share this post Link to post Share on other sites

Shouldn't be too hard using a band saw and a Dremel cutoff tool. Great idea, maybe I’ll look into this at some point. I can probably find a gear box from an old chainsaw or something and use a Dremel cutoff tool to replicate it or I could use my O&R cutoff saw....
