I have really been totally engrossed with cutting threads lately and have learned I need another tool to do longer barrels so I can index off the bore and not the outside of the barrel.
So since I could not buy what I needed for my lathe....actually I didn't even look because I saw one similar to the on another forum and figured I could make my own.
What I am making is a "Lathe Spider" for holding and adjusting the end of the barrel that would stick out the back of the lathe.
Some pics:
Here is the tool in raw form
3.5" solid bar stock.
I did not take a lot of photos through the process but you'll get the idea
I cut off a chunk trimmed it up and punched a hole through it and then used a boring bar to size it prior to cutting the inside metric threads.
Missed a couple pics here. I threaded it first then once the threads were successful I contoured the outside
Next was to notch it for a spanner wrench
Drill and tap for adjusters
Installed
Now I have one last thing to do and that is to drill the center of the adjusters and make 3/8" brass inserts to keep from scratching the barrel. I wasn't going to post any pics until I was all done but I ended up having a few minutes with nothing to do.
I still have to make another tool for shorter barrels but I received the material for that today

Sooo I am now working on a jig for shorter barrels. this will be a simple Jig and wont takes much time at all to make and I can test it on the Ruger barrel.
