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

wow, great stuff and your drawing work is excellent. I'm drawing also in SW for a couple of years but still I find it very difficult
Have you discoverd the exploded view function

Just a quick update, but I have completed the latest subassembly of the Merlin. I have posted it at grabcad if anyone is interested.

Good work so far!

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!

Do you have a full scale CAD model? I'd love to build one full size!

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

hi Rob
your work is great ive just finished a full size Packard merlin, around 50% of the parts are 3D printed thanks to files from Tom Kay. now working on a full 3D printed one. i have your cad files for the crankcase upper and lower is it ok to use it?
here is the finished one.
cheers jamie

Amazing.

 

[BertUS]

Wow, is that really one to one scale?

 

[SaparotRob]

Amazing.

And it won't drip oil on the carpet.
