I have cast hundreds of perfect boolits with this .44 mold but always had a tiny flash at the base of the back cavity. I could see a little light there but it was easy to scrape with a finger nail. Today I was getting a lot more and the nose had a large flash. I found nothing wrong, nothing between the blocks or in the alignment slots. The mold was clean.
I had to drill small holes from the top to drive the handle pins out so while I was at it I tapped the holes, shortened the pins and can now take it apart by taking out 10-32 set screws.
I wanted to mill the top very lightly but found it would not fit my mold vise without all kinds of blocks and shims. I checked with a machinist's square and there is not a right angle anywhere on the mold.
I gave that up and just lapped the top on glass with 400 grit.
I already had a set screw on the sprue plate screw so I put it back together, applied a little Bullplate lube and went to casting.
It is back to making perfect boolits that fall right out when I open it.
I have no idea why it was acting up so bad and really did not do anything but get rid of the flash on the base. A few figure eight strokes was all it needed.
But then again, it is a Lee mold! No rhyme or reason to get flash on the nose of boolits. :confused: At least it is gone now.
Now don't tell me there was something between the blocks, you all know I cast CLEAN! :Fire:
