azure Posted January 21, 2011 Share Posted January 21, 2011 Nice Perhaps the stick was a little to short? Link to comment Share on other sites More sharing options...
pyrojig Posted February 3, 2011 Share Posted February 3, 2011 Very nice rocket and header. What does your tooling look like? I was about to construct a set out of Al , and was torn between a few diff. designs.. How well does the rocket lift heavy shells, 150g or so?

Stinger Posted February 6, 2011 Author Share Posted February 6, 2011 It was made using a so called " pusher tooling".This set of rooling makes seperior rockets that can lift upto 4" balls shells ( 1lb version) without problems Link to comment Share on other sites More sharing options...

I have the spects for the tooling, just need to get to the shop to turn a couple out.... Just met a machinist that has a CNC machine... Ill see if he can help fab up some kick ass tools like star plates and such... Link to comment Share on other sites More sharing options...

With patience and strong hands, the tooling can be made at home on a drill press. I only have a 9 X 20 lathe and the thing is so old and abused that it has no feed so all movements are by hand and it takes about 2 hours to make a 1# set from aluminum stock.

Ya, I hear ya....My last 5/8 core burner set was made by a drill press. Not as fun as a lathe or CNC equipment for making tools. CNC will be nice for star plates for the most part. I can make a big and accurate plate, where the plate with the pins is half the width of the lower receiving plate, allowing for better pressures and twice the stars. Btw, what do they call that crosshatch looking grip on the handles of your rocket tooling...( the grip part) ... Does your lathe allow you to do that ?

Mumbles Posted February 7, 2011 Share Posted February 7, 2011 The cross hatching is called knurling, and yes it's a lathe operation. For the interested parties, this is the pusher tooling. http://www.wichitabuggywhip.com/fireworks/rockets/erich/index.html Link to comment Share on other sites More sharing options...
psyco_1322 Posted February 8, 2011 Share Posted February 8, 2011 1lb whistles should be throwing up 4" balls all day...tell me when they start flying 5" ones. Link to comment Share on other sites More sharing options...
dagabu Posted February 8, 2011 Share Posted February 8, 2011 A better picture of the tooling can be found on Rocket Tool Sketcher. http://www.flashnet.dk/rts/ Link to comment Share on other sites More sharing options...
Mumbles Posted February 8, 2011 Share Posted February 8, 2011 According to Eric's description, it could probably do lighter 5" ball shells such as charcoal streamers or glitters. My colored star shells typically end up in the vicinity of 700-750g. Maybe with a catalyzed mix, it could take those up. Link to comment Share on other sites More sharing options...
pyrojig Posted February 8, 2011 Share Posted February 8, 2011 Man that is really cool, how those little motor can deliver such horsepower!!! I got my prints off the same site as well...(flashnet)..Great schematic program..... Someone needs to get a prize for taking the time to make that program.. "knurling" AHHHHH that was the word I was after... Thank you Link to comment Share on other sites More sharing options...
