Bentonite - casting

Tom
The bentonite is used as the clay binder for the sand. You need about 6 lbs clay to 100lbs sand. I think the sand he has listed is too coarse for casting. You can get finer sand from Target Products.

That’s where I got my sand from they call it “ golden sand “ it’s fine grain size and packs well.
 
Excellent info - Target Products. At some point I want to do little casting and I will need good sand. I can always get my dad to help me as he is supposedly mechanical engineer with casting as speciality.
