muskietom51 Posted January 20, 2009 Report Share Posted January 20, 2009 Hate to ask this cause I know dumb lol. Poured my first mold of a 2 piece mold from omoo30 the first one came out pretty good then I cleaned it up a bit before I poured the second half stood back an reliezed I forgot the release agent dang. So will I beable to cut around the mold an separate it, or start over. Also can u make a mold out of plaster paris to form featherlight plugs. I'll learn sooner or later.

Vodkaman Posted January 21, 2009 Report Share Posted January 21, 2009 You may still have a chance to peal it apart, just be very careful. I've been there more than once. Slow down. As for the PoP, it is possible, but are more than likely going to damage the PoP, trying to remove the master. Dave Quote Link to comment Share on other sites More sharing options...
Snax Posted January 21, 2009 Report Share Posted January 21, 2009 Oh man I feel for ya! I really hope I don't do that myself when I attempt to make my first Oomoo mold soon. Quote Link to comment Share on other sites More sharing options...
K.C.K. Posted January 21, 2009 Report Share Posted January 21, 2009 If you have a compressor and I mean not a airbrush one .. Take a air gun and put it in one of your vents .. if it is going to part this should help. ..another tech is to slowly pull apart in a bucket of water. K.C.

dramone Posted January 21, 2009 Report Share Posted January 21, 2009 (edited) not a big problem muskietom51 the 2parts of your rtv mold will bond together. you will end up with 1 part. ok, its getting very difficult to place the hardware directly while casting, but you can still cut "free" you master and use the mold. shown here at 4:20 if you mold is thick enough. http://www.youtube.com/swf/l.swf?swf=http%3A//s.ytimg.com/yt/swf/cps-vfl73532.swf&video_id=ysJQmS7UHXk&rel=1&eurl=http%3A//www.smooth-on.com/media_video.php%3Fcategory_id%3D1%26category_name%3DBasics%20Of%20Moldmaking%20Videos&iurl=http%3A//i2.ytimg.com/vi/ysJQmS7UHXk/hqdefault.jpg&sk=kEWDFmkOAPfD40GjxEwi0mU_FTGYB1pWC&use_get_video_info=1&load_modules=1&autoplay= hint: if you cut at the outside "zick-zack", you have your mold keys! make small cuts for better keys. with this method, you will have minimum flashing.
