this is about 4 hours in making 3600 red 1/4 inch cores. there has to be a better way. watched a video by pyro hook putting drops of water on dry comp in his star roller. looks to be a lot faster. any body tried this ?

I saw Kimbolton making cores, Put lots of powder in a star roller and make a coarse spray of water and roll til the droplets close up as cores, screen and repeat til the powder is gone.

 

Much of the technique of star rolling is the control and choice of the sprayer(s) A coarse spray makes cores, a fine mist helps cores to grow.

Probably the best tool kit is a selection of sprayers some that make coarse and fine droplets, some that make mist and fine mist.

Ive done the water droplet core forming thing. I'm not claiming to be an expert by any means though. It's hard and easy at the same time. It's a procedure you just have to kind of go for. What I mean is that you can't really baby it. You just have to add in the water continuously and with some blind faith. I'm better versed at getting more granule sized grains instead of larger cores. Once you get there it's just a matter of giving it a little more time or a little more water.

 

The biggest thing is that this works better with larger batches. You need a certain amount of mass in there to help things build up and keep from sticking together. As a gut feeling, I'd suggest no smaller than 10lbs. Maybe 5 lb if you're trying to keep things small or have some experience. Worst case scenario, you can always take the batch and dry it out a bit and then pump them.

 

You want to add somewhere in the ball park of 14-16% water by mass. Something like a pump garden sprayer is usually fairly controllable and is much easier on the forearms than a bottle mister.

As an alternative. Get an icing pump or bag from a supermarket, (used for cake decorating) and make lots of thin lines of pumped comp, then cut these into small pieces while damp, with a knife.
