In the grand scheme of things, its not too difficult to clean up the raw casting the way they are, but what fun would it be if I wasnt trying to make it better all the time. and this might lend itself well toward future projects if I make sand casting patterns out of the material I can smooth those out faster. and it also makes them water tight! which is a plus in investment casting.

Thanks for the info. I WASN'T aware that PLA won't
react to acetone bath. I'm glad I read that, before I tried doing it!

Yes, workingn with alcohol is much gooder then acetone!

There's ALWAYS fun times trying to improve upon our projects!
