Outstanding video---I have an old Logan...and boy you aren't kidding that the compound rest is the weak point. I am going to attempt this next weekend!!

I’m picking a 618 atlas this weekend. Very excited as it’s my first lathe!

Few go into the theory of why and what’s going on with tool post deletes. I love the idea of off setting the tool post from the centreline of the boss. Also, great idea with using a circular shield on the mill. I’ll borrow that one thanks.

You've contributed to my education. Thank you.

Don. I Also live in Florida😄 I've got a !0" Atlas Lathe bolted to a 3/4 Slab 8" x 45"of cold Rolled That was Blanchard ground. The original bed was wood When I bought back in Michigan.

Great vid.

Wow!

Don, this has been one of those things on my "To Do" list for quite some time. I wish I could add something useful but I think you covered it all; especially the offset you incorporated. I'll probably make two of them. One for my QC and the other for my 4-way turret. Hell, I might make one for my Lantern tool post too! I like options. Thanks!

Very interesting video don, 👍.

Very interesting video and solution. It would be simpler just to put the hole in the center as you can make almost of the work on the lathe but of setting the tool post shurely helps in terms of rigidity. It's a project on my list as i have a relatively small lathe and rigidity is very important.

Brilliant idea and superb instructions. Just picked up a 618 two days ago with tooling on original Craftsman workbench. The owner had been given it and didn't use it. But the best part is it was advertised as an Atlas 3950 so I was pleasantly surprised. Going to make this modification in a few weeks when I pick up my mill. Do you have a recommendation on the tool post brand? Thank You

This seems to be a popular thing these days to make. I guess for small, not very sturdy lathes, it makes sense.

The only way to eliminate the bending moment between the overhung tooltip and the tool post is to mount the tool directly over the vertical axis of the securing bolt for the quick change tool post. This would mean that you'd have to make a custom tool post. You're still going to have the same bending moment between the tooltip and the QC toolpost no matter where you mount it on the cross slide.

As suggested in this video, I went back looking for some “tricks” on stiffening up the compound/cross slide in your milling attachment video but I guess I missed it. Any advice for stiffening up my qctp set up on my 12” Atlas craftsman lathe? I’m chattering all over the place. I’ve replaced the thrust bearings in the headstock, checked my gibbs etc…. I’m not having any luck. Thinking about changing out my chuck as a last resort. Any help would be appreciated

If you used a larger diameter piece of steel for your solid tool post, your quick change tool post would have more support, and it would have better friction (more area) and leverage between the bottom of the QC tool post and the solid tool post.

Don Thais a very good video, I made one like that for me milling attachment. I am going

In industry I've only ever used a lathe with the compound slide on it for the last 60 + years......those that think removing it for a solid block are amateurs......of course, if the lathe is crap any modification will improve it.

can i order one from ya?

Q

sure would like to see parting run on this setup good vid thanx
