Wow,
There's a few that I haven't seen before.

That's interesting stuff.

delta,

Thanks for the kind words.

Nice looking mold!
I checked out your web site and you do nice work.

I've got one of Mr. Doughty's moulds, and it is indeed a fine mould, as well as a fine shooter in my .454.

Very Nice Hardware, Doughty!

I didn't realize that Doughty had made that mold. Please add my compliments to the preceding list.

I wrote this about making my own fixturing, tooling, and molds. It's a couple years old and I've improved some tooling and processes since then but it still might be of interest.

Holy Sheep! you wrote that! I have been studing that so much I had to print it out!!!!!
It is a GREAT piece!

My compliments to you Sir, and thank you for all that info!

Glad you enjoyed it. The way I do it isn't the way all moldmakers do it and the methods I use impose some limitations, but it's the best I can do with what I have.

I'm hoping to finish up another ongoing project over the holiday break that relates mold cavity size to finished bullet size for different mold and alloy materials. I have to cast one more batch of sample slugs out of Linotype (I've already got the slugs cast and measured out of pure lead an WWs) and measure them. I will then compile the info and publish the results sometime this Spring. I'll post a link here in case anybody is interested.

Once again thanks for kind words.
