eb11 Posted January 6, 2013 Posted January 6, 2013 just was wondering what is the size stars for the different size shells for instance what is the size for a 2 inch shell and so forth
RodgerDodger Posted January 6, 2013 Posted January 6, 2013 I use 1/4" for two inch, 3/8" for three inch and 1/2" for four inch Shells myself... Mostly cut stars as it's cheaper... Others may use different methods? RD..
mathiasxx94 Posted January 6, 2013 Posted January 6, 2013 (edited) This is what i found for the moment: Shell Size.............................Cut Color Stars............................Cut Tailed Stars 3" ..........................................1/4" or smaller............................... 1/4" - 3/8" 4" ..........................................1/4" - 3/8"...................................... 3/8" - 1/2" 5" ..........................................3/8" - 1/2" ..................................... 1/2" - 5/8" 6" ..........................................3/8" - 1/2" ..................................... 1/2" - 5/8" or 3/4" 8" .........................................1/2" or larger................................. 5/8" or larger From Skylighter.com I know that pyrowiki had a lot of good shell building charts, but i can't unfortunately get access to the site anymore.

pyroshell Posted January 6, 2013 Posted January 6, 2013 It all depend on the burn time of your star, how high your lift slings your shell in the air, and how close you want to stars to go towards the ground.
AdmiralDonSnider Posted January 6, 2013 Posted January 6, 2013 (edited) It really depends on the burn characteristics of the star, but the table in Shimizu FAST p.252 may serve as a good starting point for fast burning warimono stars. According to him, the star size for a 3" shell is 9mm, 11mm for 4" etc.In practice test shooting shells is a good idea not only to evalutate the aerial effect and success of the prime, but also the burn duration and thus the optimum size of the star. P.s. this data refers to round stars, whereas the table above from Fulcanelli refers to (chlorate) cut stars for canister shells. Edited January 6, 2013 by AdmiralDonSnider
