Help with core making
Hi guys!
I'm struggling to find the best approach regarding a piece where I need a core diam. 10mm and length 260mm.
The core would be attached on one side of the piece.
- Sand casting:
Core using sodium silicate. Has to be horizontal.
Sustained with a pin. I fear a crack or shifting.
I could put a copper tube filed with rammed sand?
- ceramic shell
Core too porous, therefore fragile
- lost wax casting
Investment is fragile regarding length.
Any idea? Suggestions to give this core a strength?
