Thanks FrankF.C. wrote:Your sand structure looks excessively grainy. I see massive amounts of light colored bits in it. What is that? What is your sand mix composed of? Further, those three hooks won't serve to keep that sand mass intact with the upper half of that mold. The hooks are too thick, and, what you do utilize for rebar reinforcement needs to be thin and attached to a structural support within the upper half of that mold frame. I'll see about finding you an example pic, if not, I'll sketch you what I'm talking about.
The sand is the finest that I could find at 80 mesh, this is the supplier http://www.riversideindustrialsands.com ... ndry-sand/ . The white bits are new molding sand that I made a few weeks back. the mix is 10 % bentnite and two % corn flour, next batch that I make I'll do your mix 5% bentnite and 5 % corn flour
What a useless fucked up day to day was, I had to do a days training at work today, 7 hour of useless shit that big business try to ram down your throat, just to give them a warm fuzzy feeling
