greenlight Posted October 3, 2017 Share Posted October 3, 2017 I have just purchased a star plate with delrin pins from calebs site for making perchlorate coloured stars mainly.Most of the compositions I use have magnalium (I have 325 # MgAl) as the fuel and occasionally aluminium for glitter.I have heard of people ruining their tooling from pressing metal containing mixtures.Am i able to use fine powdered metal (325#) in the press or do I need to take precautionary methods each time like using a small amount of non-metal fueled comp in contact with the pins with each press?

OldMarine Posted October 3, 2017 Share Posted October 3, 2017 Titanium and Ferro-Ti are all you really need to worry about. Spherical is the worst. Aluminum and mgal haven't given me a bit of trouble so far and I've pressed a bunch. 2 Link to comment Share on other sites More sharing options...

starxplor Posted October 3, 2017 Share Posted October 3, 2017 I think that is why they have the delrin(sp) pins, to allow pressing Al and MgAl comps? Link to comment Share on other sites More sharing options...
Sulphurstan Posted October 3, 2017 Share Posted October 3, 2017 Thanks greenlight for this question. I was ABOUT to ask the same, not as far as yesterday, when I pressed my first jopetes red stars with my plate. Now we know, thanks to OM as well Link to comment Share on other sites More sharing options...
