Sounds like he's still on his way back from vacation. I was anxious too and mine must have shipped RIGHT before he went on vacation
I've had a chance to cast maybe 30-40 blanks with these over the past week. I'm a big fan. I'm not doing tube-in casting but the way I create my blanks lends itself to single cavities rather than a big block mold. I have used them with and without mold release using Alumilite and have no issues getting the parts out. Though my method may be a bit unique... I pull the plugs out and tap on a tension rod from a drum into the hole there. I'm sure a wood dowel would work too but where's the fun in that?
The quality of these over a pink silicone mold is immediately apparent. I suspect we'll see CNC machined HDPE take over the marker for that reason alone. After 100 blanks or so I was getting curved blanks from my silicone and I know that won't be a problem here. My package included the 2 tier tray and I love it. I can say the round base plate fits just fine in the Grizzly paint pot.
Eventually I'll do some tube in casting but I've been so busy making my diamond cast blanks that I haven't gotten around to trying it yet. I think you'll be very happy when yours shows up!
