I have made 3 of the radius tools so far for use on my lathe. Two are the open "C" type, the other same idea as yours that mounts to the tool post plate, using a Timken bearing between surfaces to eliminate chatter when taking larger cuts. I think after you use yours more, especially if you ever turn steel materials will place a longer handle on the turning apparatus to keep the hot chips off, and your hand not so near the turning object. Also I found it quicker, more accurate and easier to thread the initial end you started with on the lathe, then I use a mandrel as you threaded the other piece of stock. I have mandrels made for popular thread sizes to save time, as I'm sure you will save the one you made for future projects. These tools are tons of fun! Thanks for getting into the set-up, centering etc. Most vides just show the ball being cut, leaving out the only important part-setup. Thanks for the video.
I watched this again and am not understanding why you chose to braze the carbide insert other than drill and tap so it can be changed or turned to another point? With patience the holder drills and taps easy for the appropriate insert retaining screw.
This is a fantastic design, I have a Boxford lathe which is more or less a copy of your Atlas, or a South Bend, I like the design, and plan to do this utilizing the spigot on the cross slide like you have. unless I'm reading it wrong, looks like you could have cut both sides of the ball at one setting, but hey you did great, many thanks, Dave
I like using the drill press vise to get the job done. Ingenuity is great in the shop. I think you could have used the vise that was already on the mill. It looks like the jaws can be swapped to the outside on that vise. Good video!
I didn't have the correct size metric tap on hand in the shop for the screws that came with the cheap set of insert tools I was cannibalizing. I probably could have used a different size, but I wanted to give silver soldering/brazing a try. .
Great statement. What do you do when it needs changing? Plus you ae unable to rotate the cutter to another fresh edge. I spend the extra time, and hold my breath while I drill & tap all of my tool holders for the carbide inserts.
I used stock from scraps that I had on hand. The aluminum for the base and rotor is 6061. The tool holder was a mild steel, probably A36 or 1018. Both came from the drop bin at my local steel yard.

Good work. We shared this video on our homemade tools forum this week 😎
Really nicely done

Why not make the carbide replaceable like on the tool holders by using a screw and instead opting to braze?
Just found your channel and Subscribed. Very nice machines.
Looks like a Southbend heavy 10.

You might be right, I'll check.Thanks for the tips!
Nice job! I like it! 😊
Thank you! Cheers!
that will be fun when you have to change insert
Great job, I like how the tool turned out and goes to show you don't have to have the biggest equipment to accomplish anything
In the immortal words of Michael Scott, "That's what she said." 🤭
@@thehalfgarageworkshop4358 no truer words have ever been spoken LOL
Funny how one job turns into three!
Nice video. Looks like you could use a stouter portable band saw stand😉
No doubt. It's on my list of future projects.
Awesome work! One question I did have is why braze the insert on instead of drilling/tapping a hole for it?

Thanks for the video. Is it me or does the side float around inside the channel?
Nope. Sorry. Craftsman. My bad.
Nice. What grade stock did you use and where did you source it?

I would suggest you might try to slow your speaking just a bit
Thanks. I'll try to keep that in mind.
Hey! I talk fast, in life I found that people who talk fast usually work fast.
POOR SOUND
