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

I worked with solid drafting programs......
That my boy is the just otherworldly!

Lovely work so far!

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 estimates 44 hour print. Wish me luck. Say a prayer to the kami of 3D printers.

Nice work so far!

Aaaaaaand Spaghetti.

Trying again with different settings.

Aaaaaaand Spaghetti. View attachment 609267 Trying again with different settings.

It's so annoying if that happens, and usually during the night.

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

1/8th scale crankcase

I decided that in order to finance this little project of mine I would make some aftermarket engines for some of the larger scale models out there that don't really have good Merlin engines. Just for fun I printed one in 1/8th scale and was just gobsmacked at the results. So I also plan to try and make an even larger scale standalone engine kit, probably in 1/8th or even 1/6th scale.

I am currently working on the lower crankcase assembly, a.k.a. the oil pan. I will update you guys that once I have completed the casting. Thanks guys!

Incredible.

That's just cool as heck! Is the Anycubic Photon Mono X pretty easy to use?

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 latex gloves and a lot of 99% isopropyl alcohol. But it is still 1000% easier than FDM printing, a.k.a. PLA and ABS printing.

Thanks for the education!

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.

 

[SaparotRob]

Cool.

Nice work

Really nice work.

Good work so far!

Beautiful. And the originals were done with pencils and slide rules.
