BengalFlair Posted May 6, 2015 Share Posted May 6, 2015 (edited) It's rather hot and dry weather right here which is favourable for making strontium nitrate based stars,so made some and fired a 70 mm shell and would like to share with you.

pyrokid Posted May 6, 2015 Share Posted May 6, 2015 Great shell! What is the pasting method? Link to comment Share on other sites More sharing options...
BengalFlair Posted May 7, 2015 Author Share Posted May 7, 2015 Thank you Due to non-availability of plastic and paper hemis right here I usually make newspaper hemis myself or use plastic kids’ balls for my shells. This shell was made of ordinary plastic ball for kids. I cut the ball in two halves and made a hole for spollette and fixed it with glue. After loading the shell I mated two halves firmly and fixed it with masking tape. Then I applied two layers of kraft paper and finally pasted with two circular pieces of cotton fabric and wood glue from pole to pole. So it may be called a hybrid shell.

sora Posted May 10, 2015 Share Posted May 10, 2015 Great one Ben, as usual.The pink fuse looks a bit uncommon, is that handmade too? Thanks Link to comment Share on other sites More sharing options...
BengalFlair Posted May 12, 2015 Author Share Posted May 12, 2015 Thank you The pink fuse is not homemade.It’s actually a visco fuse with burn rate of about 3sec/inch which is recently available right here. Link to comment Share on other sites More sharing options...

BengalFlair Posted June 21, 2015 Author Share Posted June 21, 2015 @debubisu I think you actually wanted to know the composition of stars. It was a slight variation of ‘independencered’ and regarding visco, I don’t know the right location as I got it from a friend. @asdercks Thank you Please check out post #3 for your answer.

Shunt Posted June 23, 2015 Share Posted June 23, 2015 "Then I applied two layers of kraft paper and finally pasted with two circular pieces of cotton fabric and wood glue from pole to pole. So it may be called a hybrid shell." Nice shell! I wanted to experiement with pasting shells with heavy cotton fabric, like old blue jeans since it is so strong but never got around to it. Glad to see my thoughts might be in the right direction, as it worked out quite well for you! Link to comment Share on other sites More sharing options...

debubisu Posted October 2, 2015 Share Posted October 2, 2015 hi ,bengalFlair i came back again. i want to know ,can i substitute pine resin with redgum and pvc powder for parlon in this star formula ? because these are not available here. Link to comment Share on other sites More sharing options...
BengalFlair Posted October 3, 2015 Author Share Posted October 3, 2015 hi ,bengalFlairi came back again. i want to know ,can i substitute pine resin with redgum and pvc powder for parlon in this star formula ? because these are not available here. You can substitute shellac for redgum and pvc for parlon but you will have to change the proportion of the ingredients of the composition especially mgal and pvc to achieve an acceptable red star. Following would be a good start for you-Strontium nitrate-50Magnalium50/50 (200 m)-22PVC-12Shellac-10dextrin-6 Link to comment Share on other sites More sharing options...
