Hi all
I recently needed a part machined for a special gear/cam and was delighted to find that I could use my existing 3D software and design the part, export the file then get it made at a local CNC machine shop or rapid prototype business. It's not as cheap as mass production but at least it lets you get your idea from theory into practical.
I am willing to do similar CAD/CAM work for those of you who don't have the tools or know how, at a reasonable price.
