Cheers Lee, all good info.

Tiny update:
Drilled 3mm pilot holes ready to open up and tap to M5. These are peck drilled right through the 20 mm part using a 1 mm peck with full retract in between, and dab of oil each time the drill comes out of the part to clear the swarf. These take the leveling grub screws:



Then the part was flipped and the counter bores machined for the M12 cap heads:


Then bolted down onto the top slide using the T-nuts I'd made for another fixture. The M12 bolts are a bit long so will need to cut them down. They will hold onto the side of the spindle block which already has M12 holes in it. There are some random threaded holes in the part but they were in the piece of scrap I made the part from:

Look forward to seeing the lathe work, will you be video'iiinngg it as you machine it?

OK, as requested here is a video of making a fixture, setting up, and then line boring the spindle housing . . .



Still lots to do but another step closer.

I've decided to do another video, which takes much longer to put together so let me know if this is better than posting pictures.

In this video I attempt to align the 4 rails flat and parallel to each other. They still need lateral spacing/alignment but that will be the next step when it is assembled into the Y axis and they are trammed in. Here are the edited highlights:

It's always a joy to watch a true crasftmans at work

great work, with the level of attention you are paying to the details this is going to be a very impressive machine at the end!
