only fixed 75% of the prob?Alright, I'm back after doing a bunch of experimenting. This forum is awesome so the least I can do if add my thoughts to someone's search.
The wax was 75% of the problem. I read a bunch on here about machinable wax, but in my lab the resin did affect the fit. I went back to the Harvest stuff and 75% of the problem disappeared! Wax is cheap, don't cheap out on it!
the remaining problem was milling too thin with certain die shapes. Especially barrel shapes with undercuts that were very thin. I've increased my minimum thickness to .7mm in the mill.
And finally tweaked my mix ratios in investment to tighen it a smidge.
I didn't want to go back to slow burnout if I didn't have to.
Problem solved!
Thanks everyone.
i have been playing around with a dozen or so milling waxes until i found some decent ones. TDs wax is nice, the zirlux wax is decent, whipmix vericore wax is okay, so far jensens milling wax gives me the best results continuously. im always looking for that right mixture of resin/wax to get the best results.
