There is a big difference between a 3D model, and one that is useful to make foundry tooling.mekilljoydammit wrote: ↑Mon Nov 05, 2018 9:54 am https://imgur.com/a/kgTkdG0
Just something I was working on, speaking of reverse engineering cylinder heads. The fun trick will be turning the slices into a 3d model but I'm pretty sure I have a way to do that without too much work. edit: Well, I suppose I should say "too much trouble" - every step of this is a lot of work.
If you're dedicated enough, you can DIY the foundry work too but I have no doubt that getting to routinely acceptable head castings will be a learning process. There's a lot of technical literature out there to let you crib off of what people have done before. Patterns and stuff are even more easily DIYable.
I am not, however, sure how to get any money out of any of this, but it keeps me out of trouble.
Simply lofting a bunch of sections won't develop a usable parting line.
There is no alternative to developing the CAD skills and foundry tooling knowledge if you want to be competitive.
