I should of know that today wasn't going to be worth a damn when I had to dump this in the muller to keep it from freezing in the crucible.
anyway after above fiasco of running out of propane due to oil line on burner not wanting to cooperate and me getting some more propane I continued with the day of casting fun, oh yea the PID in the burner control box with the thermal couple laying in the grass said it was a balmy 119 degrees.
I fired up and started for the second time today, I achived pouring temp and in the hast I forgot to turn on the video camera so sorry no video.
But I was really happy with the way the mold filled. Even after I shook it out of the flask heres a shot of the gating the part broke off in my rolling it around cleaning sand off of it.
see that little place there were the parts suppose to be at that should of been all the hint that I needed that this wasn't going as good as it looked
and heres the part that I was after a replacement for the swiss cheese one I did on Saturaday.
a different shot of the part
I should of know that it felt a little light but and after cutting into it here is what I get for all my troubles. All I can do is laugh and get ready to do it again, the core did what it was suppose to it left a hole in the part.
damn good thing I didn't have to pay for this or I would be really PO'd
