Great photos. Norm, what did you use for parting dust? I like the baby powder container, I use an old stocking, but I may try your method. Your green sand worked very well, no sticking, no dropouts. Where did you get it? And I love your snap flask. Great job. I looked at all 39 pictures, but where is the pour and final product? I am waiting for the next exciting episode. Tune in next week, same bat time same bat channel.

parting dust is dollar general baby powder. When you get the(baby powder) talc power make sure its only talc and not corn starch with talc.
I made my sand from play sand bought at walmart sifted out the big stuff. I ground up in a blender, some of Rufus's cat litter (fresh unused) Benoite clay. Its the clumping cat litter with a citrus smell.
1 lb clay to 10 lbs sand mixed it up by hand and also put it on the shop floor and walked on it
mixed it up and walked on it a few times.
Flask is home made.
I have all the patterns made except for the last one for the shaper, I did a test ramming of all patterns yesterday to see if I can pull them with out damage of the mold ,one pattern had to have some light sanding on one corner so it would pull cleanly the rest worked good.

May try it tomorrow. You want to play? We could do some Saturday if you want and the weather is good. I need to get some used oil I have very little right now.
I still need to get some 5/8" plywood or particle board to make the shaper table a chunk about 2' sq. should be enough I might make it out of 3/4" ply as I have some that will make the table just a little thicker so it shouldn't hurt anything. Once the table pattern is made I will have all of the needed patterns made.
I still haven't taken any photos of the patterns, I liked your photos of the cylinder head mold.
I might need to make more sand as the biggest flask will maybe take all that I have made and still need more to fill it completely.

Hi Norm,
The do it yourself green sand is exactly what I did. I used a coffee grinder to get a powder consistency to the kitty litter. A blender didn't seem to get it fine enough for me. I guess my mistake was either too little bentonite or water amount was wrong. I used 8 parts sand to 1 part fine sifted sand. But I did by volume (margarine containers. The clay weighs less, so I probably did way less than 1/2 of your ratio. I'm gonna try this using your method. Hopefully no more dropouts. I am posting this so if anyone else decides to try it, they will see common problems, and avoid the mistakes that can easily discourage people. Good luck with your project. I can't wait to see a pour. Jim
