Senkosam Posted November 1, 2004 Report Share Posted November 1, 2004 Del has a few very good tips on his site worth reading. http://www.del-mart.com/index.php?module=PostWrap&page=http://www.del-mart.com/htmlfolder/mixing.html I am impressed with the inventory and the quality of products. His prices are good and selection improving for molds, dyes and glitter. Sam Quote Link to comment Share on other sites More sharing options...
BuMMeRBaits Posted November 4, 2004 Report Share Posted November 4, 2004 Senkosam - as we were discussing on another topic, about the microwave with the plastic getting little bubbles in it. Last night I found out something interesting. The first batch I poured up I used my wodden pop-cicle sticks to stir and had lot's and lot's of the small bubbles in the plastic. On the second batch I did, I used a metal stirring stick and the were hardly any bubbles at all. Quote Link to comment Share on other sites More sharing options...
nova Posted November 4, 2004 Report Share Posted November 4, 2004 I've been using old table knives since day one. Wooden sticks didn't appeal to me because of the color transfer and the difficulty of cleaning. Quote Link to comment Share on other sites More sharing options...
Travis Posted November 4, 2004 Report Share Posted November 4, 2004 From early chemistry class if I recall wood stir sticks have this problem. Air is trapped in the wood and as the stick heats the air expands and escapes into the plastic. Quote Link to comment Share on other sites More sharing options...
Senkosam Posted November 4, 2004 Author Report Share Posted November 4, 2004 Bummer, sounds like a plan. I'll take the metal handle of a fork or spoon and stir using it, instead of wood. It can't hurt to try. (The microbubbles are good for super floatation though!) Sam Quote Link to comment Share on other sites More sharing options...
Markell Posted November 5, 2004 Report Share Posted November 5, 2004 I'm gonna bring my plastic inside. I have all but stopped pouring plastic with exception to the two part molds because of bubbles. I live in Georgia and we have high humidity. I have also found that glitter can compound the bubble problem. Quote Link to comment Share on other sites More sharing options...
benton B Posted November 5, 2004 Report Share Posted November 5, 2004 The hot plastic causes the trapped air in the wood to escape. We crankbaiters had the same problem with wood while mixing epoxy for topcoats. Quote Link to comment Share on other sites More sharing options...
