Sarge Posted December 15, 2015 Share Posted December 15, 2015 Both of those new plates look good. Have you tried stacking any of the "new" stars into a shell casing yet?What's the fit like?I like the idea, maybe they're a tad too big though. What size shell are they for? 3"?Sarge.

starxplor Posted December 16, 2015 Share Posted December 16, 2015 I dont do canisters, but that idea seems like genius to me! I am expecting an arbor press for xmas this year, being able to print one or two of these plates would be an awesome money saver. Link to comment Share on other sites More sharing options...
Sarge Posted December 16, 2015 Share Posted December 16, 2015 Well I broke it.... Just one pin. I'm not sure if I knocked it on something or during use. I only noticed it while I was cleaning it after doing a few more plates of stars. I'm pretty sure I can repair it with some super glue. Link to comment Share on other sites More sharing options...
taiwanluthiers Posted December 17, 2015 Share Posted December 17, 2015 Depending on the plastic super glue may not be the best choice of adhesive. If It's PE based then no adhesive is good. If PVC you will need to use PVC cement, and if it's ABS you can use MEK/Weldon to weld it in, and it will be as strong as the material itself.

Pyronaught Posted December 27, 2015 Share Posted December 27, 2015 (edited) So the star comp does not get stuck in the layer lines of the printed cavities? I've been experimenting with 3D printed star plates and gang pumps too, but I've been using brass sleeves and brass pins and just using ABS as the plate material. ABS allows the pins and sleeves to be press fit without cracking the plastic the way it would PLA. I never use PLA because it's melting point is just too low. If I wanted to use acetone I would just print it with PETG. Trying to pump acetone bound stars is a mess anyway and tricky to do. That stuff just dries so fast there is no working time. But yeah, now matter what the plastic is you are going to need a metal plate on top the pin plate to distribute the load if you are using this in a press. For hand pressing using a rubber mallet you could just whack the plastic though, although PLA would likely crack. An ABS one would be able to take the mallet strikes though. Skylighter used to sell an all plastic star plate like this years ago and it worked OK. Edited December 27, 2015 by Pyronaught Link to comment Share on other sites More sharing options...
