I have a big interes on this latest T-slot construction.

I haven been planiing/doodling a new top slide for my small lathe. Original is that shitty that it is next to useless. I use it only when i can't avoid it, other times it is replaced with a rires block on the cross slide - much better and more stable. It also has two holes for mounting this riser, places are defined to maximize working envelope, original fixing point wast not even compromise, it had bad sides from the tool overhang and diameter capacity.

Milling the T-slots is the industrial practice, but not always easiest to do in HMS. And tou need a bigger piece on stock to start with.

Fabricating the pieces gives you more versatility and you can replace the parts. Also looks easier to make on small mill.

You planning to align the T-slots accurately with the top-slide I.E. nearly perpenticular to spinde axis?

Sorry Andrew.

Pekka the holes in the cross slide and the T-bars were all done on the mill. Admission: unfortunately the first time I drilled the cross slide I hadn't checked the mill vise from the last time I'd used it, and it was slightly off perpendicular.  :palm: :wack:

But, since I decided that 1-3/8" spacing between rows was smarter than 1-1/2" (because I could use 1" wide bars instead of 1-1/8), I plugged the old holes, indicated the vise in accurately, and re-drilled everything with the altered spacing. Because of the change in spacing, none of the newer accurate holes impinged on the old holes. so it was all in new material. Then I tapped them. So to answer your question, the T-slots should all be accurately parallel with the bed ways.  :med:

Pekka, you might recall I did a similar Tee-slot table before, though that time I just added the tops of the Tees:

Thank you, I remember that one, but it was good to read again.
