So had asked on a FB casting group is my mold was filling out enough and according to alot of people only like two of my bases where acceptable.ive been gas checking so haven't really though they looked that bad but guess not. Anyhow anyone wanna give me some advice on with the problem could be ?
Lee .225 6cav mold ( it's a used mold and is a little rough )
Molds been heated in a hot plate for 20 or so minutes prior to use.
Used mold so is a little dinged up
Lead is 100% clip on wheel weights. Actually more like 95 because I did add a two ingots that's had a bit of stick o WW mixed in
Lead temp was 750-800
Was fluxing about every time I saw the lead get out of that mirror silver color
I was cutting the sprew as soon as I saw the lead change to that dull grey color like I've been told. And I think that's it for details.
I had some people telling me it looked like my sprew plate had called my molds surface and I should hone it. Also had some more people say I should lube my stuff better.
I went and filed, then sanded all the touching surfaces down level with 320 -1000 grit sand paper ends up the mold wasn't flush completely ( least that what I gleaned from using my straight edged to check) the sprew plate was also bent up slightly so it wasn't cutting even.
I'll post some more pictures of what I did to the mold but before that what could have been the problem?
