Setting your quick change tool post .....

[toolznthings]

Here is the method I use to set up my QCTP on the lathe to make the least amount of set up on the tools I use the most. I set the compound at 29 degrees for threading, or whatever you prefer. Then I set the tool post face square / parallel to the face of the chuck with a 1-2-3 block.

Now I can position my cutting tools in the holders with no need to move them again. Such as ... threading tool, parting tool, turn & face and all the boring bars are inline with the lathe bed. When I do need to move the compound or post for a special operation it is easy to return back to the original setting with the 1-2-3 block and the compound back at thread position. No need to adjust the tools in the holders.

Good idea... As a new-to-machining-guy, I like to see people's tricks. Thanks for posting that.

I've been enjoying toolznthings tips-n-techniques. Thanks.

Is there an advantage to using the 1-2-3 block rather than just coming up against the chuck jaws?

Hi,
I use the 1-2-3 block because I can't get the tool post up to the chuck face with the jaws in the way. Especially with the smaller 5" chuck. The 1-2-3 block is convenient, a parallel or any other accurate block would work.

Hi Brian,
 Can't remember if I saw this posted by you some place else, but I started using it & it works great, it makes setting tools square very easy, great for thread cutting. Been trying to work out how to hold the block, then an angle gauge, and adjust & tighten the topside all with two hands to cut better angles.
