Hey fellers,
Just got my first NOE mold the other day, a 360 WFN RG2, very nice looking mold! While waiting for it to arrive, I read up RG type molds so I could avoid start up problems. When it came, I broke it in with 4 warm ups and cool downs, dehorned the pin retainer, and smoked the pin tips.
Yesterday, I went out to the shed and fired up the pot and hot plate. Had the mold up to 350* and the melt @ 800*(bottom pour) when I started casting (I Bullplated everything up first). Yes, I had the mold a bit too cold, the mold was hard to open and the bullits took a few wacks on the handles to fall from the pins, so back to the hot pate it went. At 400*, started casting again, mold still hard to open, but bullits jumped off the pins! So I figured I would just "cast through" the hard to open part. The next few cast I noticed that the bullits were constantly sticking to the non-pin half of the molds, and the pins were having to drag the bullits out of that half of the mold in order to open. Needless to say none of those were keepers as the lube grooves were torn up from being dragged out of the molds at an angle. Chalked it up to virgin mold.
Tried casting with it again today, same problem, bullits still sticking to the same half of the mold. Now I'm not complaining just yet, I understand that all molds break in differently, just looking for some advise as to what I'm doing wrong, need to start doing or just try casting a few more sessions to break it in good.
Thanks, cutter
P.S. Has anyone had to "Leement" their RG's to get it to work right?
