I made the T-screw on my Atlas 618. I know the things I make are so simple to real machinist, but it is such an accomplishment for a new dude like me. The one I made is on the right. If you want to see how I made it, and the 3 other times I failed, you can watch my youtube video. It is #7 in my "Journey to Journeyman" series. Thank you in advance.......

Even though you boogered up the first couple of attempts, you kept at it and got a good looking product in the end. One thing is for sure, you won't make the same mistake the next time you cut some threads.
 
Hey great videos on YouTube. And a very good job on the lathe rebuild. This is my first post hope it works
 
Looks nice Jester!

This is why they say the lathe is the machine that recreate itself!
Exciting to make parts that improve your machine too

grandpaswagon: Thank you and you are so right. My next project went pretty well. Well, I mean I didn't make that mistake, LOL.

kycastings: Your post worked. And thank you very much! I did my best on the rebuild. And I made tons of mistakes, but it seems to be working very well. Thanks again.....

itsme_Bernie: Tru dat! The lathe is an amazing machine. I love it. And thank you very much.....
 
The Liberal Arts Garage: Too late, I already made another part, LOL! And, Thank you very much....
 
That's a good video clip , Thanks


Getting the root of the thread

If you have enough metal perhaps turn a step to the correct thread root dimension on the end of the bar and use that as the guide/helper to getting the depth of the thread .


Engineering wise & for practice at fiddly things ..... instead of gluing metal .

Re:- The pin you put through the clamp bolt's head if you noticed .....in your vidclip there is a " PINCH " in the bar which makes for indentation lips on the bar that secures the bar in place .

Lay the bar across the jaws of an almost closed vice and give the bar a smart cut with a hammer & narrow cold chisel to make the cut and raise the lips then tap the bar into place . First mark the distance with a fine sharpie etc so you don't knock it too far in .

OR

Gently dot punch the bar a couple of times around the mid length point then tap the bar equally into the bolt head.

Or

Give it a firm tap with the ball end of a ball peine hammer to make a slight flat on the bar that will cause an interference fit .

OR

You could also Knurl the middle of the bar if you have a knurler ,the small indentations raised should hold in a precision hole .
