Has any one made their own venturi sand blasting head to use on a
water blaster? if so any clues?

No, but some clues. They work on the venturi principle. High pressure
nozzle firing across an angled intake pipe. Output nozzle needs to be
hardened steel as a minimum, ceramic is best.

You need a big FO machine to effectively run a wet sand blaster. 200bar @
20 lts/min or above IME. They are a PITA to clean up after & suffer from
blockages if the sand gets damp.
