    I’ll see if I can start on the base next

    3D printing an engine frame?

    Great! I’ll zip them so others can use them. I haven’t added the mounting holes to the ring gear, or modified the spur gear to add the crank. Perhaps someone better than I am can do those? John W

    3D printing an engine frame?

    That looks great! Like I said, I can’t load the files, any help would be appreciated. I’m using the Mac version and trying to export it in a different format isn’t working either. Any pointers? John W

    3D printing an engine frame?

    I've been attempting to attach the FreeCAD files to upload, but they appear to be unrecognizable by this site. Anyone have any ideas why a .FCStd file cannot be attached to a message?

    3D printing an engine frame?

    I have a partial on the ring gear and spur gear I can share. I haven’t drawn in screw holes on the internal ring gear, and haven’t added the spur gear changes that’ll include the crank throw yet, but it’s a start! When I can get to my computer (I’m on my iPad at my cabin presently), I will...

    3D printing an engine frame?

    Thanks Andy, excellent advice as usual! I’m trying to draw Elmer’s Geared Engine (I believe it’s number 5), the one with the inner ring gear. I’ve gotten the ring gear and spur gear modeled already, and will begin the frame valve box, and cylinder. I’m planning on using a glass dashpot as a...

    3D printing an engine frame?

    Agreed! About 12 years ago I had a student license for SolidWorks and I was doing real well with it, but that was when I had a Windows computer at work to use. Powerful program, and as a veteran, I am still entitled to student rates with that program. However, I’m a dyed in the wool Mac user...

    3D printing an engine frame?

    My sons gave me an Ender 3 V2 for my birthday in April, and I don’t think it’s been off more than a dozen hours since I got it. What a hoot! I’ve been printing gears in PLA to experiment with, and when I can get my experience level up to where it should be, I’ll try moving over to Nylon for...

    Terry, this is exactly as I expected it! Truly fantastic work, an exquisite running representation of a fine engine. I only hope that some day I can come close to your level of craftsmanship. Thank you for sharing! John W

    Machining 3D resin printed parts

    Excellent advice, I forgot completely about CHEP! My sons pointed me to him when they gave me my printer, I use his bed leveling program already, and it’s a great tool. Thanks again! John W

    Machining 3D resin printed parts

    As a new owner of an Ender 3 V2, I am very interested in pausing and placing all manner of metallic items in my prints. I’m new to the whole game, use Cura Slicer, and just getting acquainted with the software. Does anyone know if there’s a patch or code to cause the print to pause at a...

    Mini diesel engine.

    I’ll be following this thread. I’m also wondering if O-rings would work, and thinking that perhaps a hard nylon ring (or three) might stand up to the abuse if it didn’t have too much of an “overhang”. Keep us posted! John W

    Nice recovery Terry. Glad it worked out so well, I worried that your crankshaft received irreparable damage, but knowing your ingenuity, I figured you’d already have a plan! John W
