'Just got this yesterday.... and I think my problems understanding gas checks has been answered by you guys. Thanks a million!
These are dropping at .4625 with 50/50 and 2% tin. I heated it up on my hot plate and started out with the pot at 700 degrees and slowly worked up until I was getting good fill-out and sharp corners, and it wasn't until I hit 805 that it began looking good, and my best ones came somewhere in between 810 and 850. I know that is pretty hot, and I had to keep some wax handy and occasionally stir the tin back down in the mix, but for some reason, I just can't cast at 725 like everybody else. Either that, or my rotometals thermometer is off. I haven't tested it in any way. I am building a PID, but right now it's still just a box of parts from Auberin's, as I still have to collect some stuff from Radio Shack.
Anyway... as I said, they are dropping at .462+, which is great, and the GC shank is at .428 and the Gator check is just making a little snapping noise as it pops perfectly onto the base. So I'm hoping that when I size em, all will be just smooth for my first time using those. I gotta hone my .457 sizer out to .460, so these haven't been through a sizer yet.
I got all of the pins with it, but I just used the deep and shallow HP ones today. I didn't have any problem at any temp with them sticking to either mold or pins. I guess the heavy ones just pull themselves off, even the cold ones at the start.
