Dean411 Posted June 22, 2012 Posted June 22, 2012 I made this plate over the last few days on lunch at work 5/16 diameter 45 pins makes 3/8 diameter primed stars. I am also using this same spacing layout to make a 45 pin 3/16 star core making plateWhich after pressing can be dropped into the roller and another composition can be rolled on top.
garyrapp55 Posted July 2, 2012 Posted July 2, 2012 That is really cool. I thought of making one from plexiglass but I question its durability. Yours looks professional.
wymanthescienceman Posted July 11, 2012 Posted July 11, 2012 I like your star plate, it looks good, you do nice work I saw you said you were going to make a 3/16" star core plate, and I figured I'd show you how I made mine. I made it out of 1/8" Aluminum plate with 1/8" diameter stainless steel pegs press fit into the upper plate. http://img52.imageshack.us/img52/7690/img20110802224800.jpg http://img266.imageshack.us/img266/2510/img20110802230009.jpg http://img12.imageshack.us/img12/3160/img20110804002934.jpg http://img171.imageshack.us/img171/7494/img20110805142725.jpg http://img21.imageshack.us/img21/8453/img20110805142739.jpg I use it for pressing small 1/8" long cores/micro stars for small shells and effects. And yes it did take forever to center punch, drill, de-burr, re-drill the hole plate for clearance, and press fit all 100 holes/pegs!
Dean411 Posted July 11, 2012 Author Posted July 11, 2012 Nice job on that plate. I prefer to write a program and run the 2 plates separately that way I can make the pin plate a press fit and then use a drill.005 or. 01 over for the hole plate so that the female glides right on the pin plate
wymanthescienceman Posted July 12, 2012 Posted July 12, 2012 You did yours with CNC then? Boy would that ever be handy, if I had access to CNC I would be able to get a lot more stuff done

Boy would that ever be handy, if I had access to CNC I would be able to get a lot more stuff done I am a machinist by trade and do "Government" work as we call it on my lunch break or after work.I run CNC lathes and machining centers along with the occasional need for the hand cranking of the wheels on the Bridgeport. And yes it definatly makes manufacturing special tools a little less of a pain. The air conditioned shop is a nice touch as well.
