A few members have expressed an interest in this process, so I shall endeavour to describe my efforts in as much detail as possible.
There are numerous websites which detail the process. I have been using this one: Electroforming Resources for Aspiring Artists
My patterns for the first couple of test pieces are 3D printed in PVA resin, which is soluble in water, making for (hopefully) easy removal when the plating is complete. The parts are built with the minimum of material, i.e. single layer wall thickness and just enough internal support structure to enable a successful print.
One end of each part is pierced and a copper wire (recovered from old domestic wiring) is pushed in. This will form the electrical conductor for plating, and will also support the part in the tank.
Thank you for your sharing.I'm quite happy to create a separate 'how to' thread.
While I go through the development process, I'll keep posting in this thread. When I have made some successful parts, I'll write a dedicated thread with all the information in the correct order - plus a link to this thread for those who want to see the 'warts and all' trials and errors.
I can relate! So glad I bought a tilting rotary head now. No way I was messing with the mill head.Cylinder heads are relatively simple, but as with some other parts, I made more work for myself by designing them with radii which required multiple rotary table setups and a combustion chamber shape which required a fixture to angle the head at 5 degrees from the rotary table surface.
