Expander spud and seating stem

I was setting up a dedicated Hornady LnL AP for 308W cast and needed an expander insert for the Lee universal expander and also a flat pointed seating stem for the Hornady seater. So I cut some sections of 1144 steel and machined these 2 parts in my old chincom mini lathe last night. The expander nose section is 0.3075" as the sized 31-155W is sized to 0.309". See, even with the el cheapo Horrible Fright lathes functional parts can be made.

Yup.

I made a straight-line powder-thru-expander die for my .308, similar concept to the Forster Benchrest seating dies. Stuffed it all in a long rifle charging die. The sliding sleeve was cut with a chamber reamer to perfectly align the case body to the expanding spud. Had to make the spud from 5/8" O-1 instead of 9/16 because the die was bored to about .567" and I wanted a closer fit to eliminate wobble. You can part 5/8 tool steel with a chinesium mini-lathe using HSS but you'd better have your feeds, speeds, tool height, lubrication, and blade sharpness/geometry dialed in. Making a carriage lock helps a bunch, too.

You guys that have the skills and machines to make your own reloading tools are my heroes. A significant percentage of my reloading kit consists of dies and spuds made by Buckshot, and to run castings properly in mass-produced rifles requires tooling that the mass-market toolmakers do not offer.

I need to point out that the enthusiast does not need to be a master machinist or have top of the line tooling and machinery to craft custom tools or parts.

I would never consider myself the equal of some of the masters on this and other sites but I do try and emulate them and even though my self-made tools are not as polished they do get the job done. Even though I can program and use the CNC machines at my disposal I typically just use my old mini lathe or mini mill to make the parts needed because of habit and stubborn pride, old school Dutch characteristic.

I stand in awe at the custom mold makers, such as Tom @ Accurate, and don't know how they can afford to deliver their top-notch products at such an affordable price. As the prices of even the utilitarian Lee molds have sky rocketed the decision to spend a little more to get a top-notch mold that matches your specifications becomes a no-brainer. I used to be in the camp of spending a lot of effort to modify Lee, and other, molds to fit my needs but the custom molds are the cheaper option unless your time is free.

I frown upon the opinions in threads regarding what lathe or mill to start with or buy that insist that the minimum entry level meets a much higher level or price than what could be purchased from places like Horrible Fright.

I am a rank amateur.
What I like is being able to make what I want or what my guns want.
I have way more bullet sizers than I would if I as buying them. If I want to see if .001 smaller or bigger would help I go make one and give it a go.

Iowe a ton to Buckshot and Keith who gave me guidance before I bought my lathe. YouTube was a hell of a good educational resource.

The most important thing is a natural curiosity to see what happens if I try something. Now I can just try it and keep it to myself when it fails.
