Cross Slide Exstension

[Smithdoor]

My build on cross slide exstension
Add over 1" of travel

Milling the exstension note the drill bit use for line up the holes to the flat.

IF NO MILL JUST CHUCK UP AND TRUN FLAT

Threading the cross feed screw
The other end is unfinished

FINISH THREADING

READER TO INSTALL

I guess this means I am not the only one mad enough to add extra travel on a cross slide then....

This is one of the mods I am doing with the 7x I am rebuilding. New feed screw, new boss to take bearings plus a split nut.

I would think it questionable that a screw cut with a die would be possessed of any degree of accuracy, as it seems that the longer the thread, the likelihood of camming of the thread increases.

I would slit the nut but as the screw wears it makes to problems. So just use a one piece nut.
I had one lathe that had just you could zero clearance in center but the ends was to tie.

As use the screw it wears and there is no accuracy in screw.
I use for some work a dial indicator and skip the dial.

Still going with a split nut.

I am not worried about wear as I can always swap the nut halves for the (multiple) spares I am making. Besides, the new feed screw will not wear so much given what I have in mind when I have finished machining it.

Sounds good
