I cranked out a simple taper bar within a week of getting my lathe.
It was crude & I intended to upgrade it once I got all the necessities
out of the way but you know how that goes. It worked so well, I
left it untouched for almost 10 years. Then I saw the clever way
some others mounted their bar & it encouraged me to work on a new set
My original set up had a huge vertical misalignment between the cross
slide and the taper bar. Sure, it worked - but logic says that the
closer they are in alignment, the smoother & more efficient they will
These were the components needed to attach the taper bar base to the
ways of my lathe.
This bottom view of the taper bar base shows the range of adjustment I
have to pivot the bar.
This phantom view shows how the clamp mounts to the ways and how the
base mounts to the clamp.
In the left picture, you can see the pivot point of the linear rail.
The rail is installed in the next picture. I can now pivot the
rail easily about the center until I have the desired taper, then lock
Now I can attach the cross slide the taper bar. The Heim joint
provides a simple method of connecting the cross slide to the taper bar
while maintaining almost zero slop.
It's easy to see how much nicer the alignment is now. The taper
bar is now smoother than ever.
