I was especially intrigued by the interior work... jaw-dropping. Engine bay details are astounding as well.
I have gathered/built a forge for smelting/melting aluminium, bronze, brass. It would be cool to take your 3d printed parts and cast them, but you can accomplish most that with machining as you have been too. That x member and the bed mounts would look cool! NOT KNOCKING on your work in any way!
