    I'm doing a CAD model of a Packard V-1650-7 Merlin engine for fun and thought I'd share the progress.

    The models I am posting to grabcad are all in 1:1 scale.

    Just a quick update, but I have completed the latest subassembly of the Merlin. I have posted it at grabcad if anyone is interested. Free CAD Designs, Files & 3D Models | The GrabCAD Community Library

    Just a brief update to let you know I've finished the Lower Crankcase, a.k.a. oil pan, casting. I've put it up on my grabcad page if anyone wants to see it.

    I basically plugged it and didn't even print a test print. These were my test prints and they were perfect at stock settings. Now, that said, resin 3D printing requires a good deal of cleanup and the resin can give you a nasty rash if you get it on your skin, so it requires a breather mask and...

    I gave up on the CR-10S printer it just never worked well and never gave an adequate result. So I switched to an Anycubic Photon Mono X, and I gotta say, I'm a bit giddy with the results. You can see a couple galleries of the two prints I have done on it below: 1/24th scale crankcase...

    Aaaaaaand Spaghetti. Trying again with different settings.

    I've been working on the oil pan on and off for a couple weeks now but I don't have enough to post yet, but I thought I'd take advantage of my down time to upgrade my 3D printer. And of course, what is the first thing I have to print? Take a guess: It's currently an hour and a half into an...

    Hawker Typhoon car door cockpit

    I don't think they'd have two separate inner door panels as this would significantly increase weight without a purpose other than maybe aesthetics. It's mostly likely a revision to the door design. I can see significant difference in the doors aside from that one panel.

    Woohoo!!! I've finished the Crankcase assembly! You can read a little more about it on the blog and it's available for download on GrabCAD.

    Packard Merlin Illustrated Parts Manual (V-1650-7) (AN 02-55AC-4) from 1945 or older

    Hi guys, some of you might now I'm doing a CAD model of the V-1650-7. I have several copies of the Illustrated Parts Manual for it but unfortunately they have been revised post war (1947 and 1949). Because Continental took up production late and post war they made some changes to the Bill of...

    There are enough castings out there in the shops that I doubt anyone would need to start up production on casting new parts any time soon. I might try my hand at 3D printing some parts, tho.

    WOOHOO!!!! The crankcase is done!!!! After about a billion holes and a lot of other machining the part is complete. I decided to do a couple of renders to celebrate. I also played around with the materials in a few renders, but here's what I settled on. I did a little work on the BOM as...

    P51D schematics

    My previous comment was unrelated to what you are saying, It was posted in error but I can't remove it so I wrote to nevermind.
