TYRONEEZEKIEL Posted August 23, 2015 Posted August 23, 2015 Exactly what benefits are there in a 3" shell for round stars exclusively? They are harder to light than pumped, they are too small for a color change to be productive. If you are having problems rolling currently with single colors, how do you think you will be able to roll color changes? It is an extreme amount of work to roll a small batch. The stars require the most effort and control while they are starting. Until they get a little larger than 1/4", they are a pain to roll. If your stars are raspberrying, you might as well make cut stars since burn times won't be precise with raspberries, and that is quicker than pumping. For starting cores, I prefer a 5 gallon bucket. For rolling stars, a round drum or bowl is much better

TYRONEEZEKIEL Posted August 23, 2015 Posted August 23, 2015 It can be done, but with stars that small, you run into most of your first color burning off when the shell opens up. Unless you use oversized stars, the color changes will be very quick. Starting with cut stars will definitely work, but you run into the problem of the sharp edges causing your color change to happen at different times.
Bcorso85 Posted August 24, 2015 Posted August 24, 2015 I roll with a 16qt stainless steel mixing bowl, I usually roll 100 gram batches. For color changing stars,I will use precisely-cut 4mm cut stars as cores. Is it easier to roll a small batch and control the star size ? No. Smaller batches are more difficult. As previously mentioned a larger batch with more weight helps roll the stars and hedge against raspberries. If rolling cut star cores I believe you need a round bottom bowl to build a layer on top of a cube. A hemispherical bottom is what you'd want, not a round bowl with a flat bottom.
Bcorso85 Posted August 24, 2015 Posted August 24, 2015 ** using the 4mm cores will be somewhat easier. But in F.A.S.T. Shimizui suggests the round bottomed bowl or device to help evenly apply the delay or primer or composition to the cut star, ultimately making it rounded. But I agree 100% with Tyroneezekiel. The timing most likely will be off.
