My plan is getting more ambitious, so at this stage I’m just dreaming.
As the shape is going to be very complex, it could be milled an original in a soft material like plaster, then cast cheap copies. Before someone says that’s impossible with copper, I agree. I’m thinking in silver.
Jewelers cast all the time complex minute details with simple equipment.
Jaydee, maybe you missed a decimal in your slope calculations, it should be more like .003
The water goes to a perimetral channel of a growing section and exit in only one barb, just like good centrifugal pumps. All the channels and housing of the block will be in casted resin, so the only metal required is the silver disk. Actually the disk is 28mm diameter and 2.3cc volume. As silver density is 10.5 I will need about 25gr of silver. That shouldn’t be expensive, anyone knows?
This is using just the crappy modeling of Autocad 2k2
