How about fixing the links!

hi all- here's the new link to all articles related to the build. enjoy and happy holidays!

Thanks for fixing that - some of the links still seem broken, but most of the interesting stuff is back

Did you really drill all those holes in the base and Y-plates with a hand drill? How did you do it accurately enough to maintain parallelism across such a large distance?

hi- the links took a while to get back up.. and there are more site changes coming

re: hand drilling. yes. a large mill would have come in handy, but the bolts used allowed a bit of adjusting the rails to within acceptable parallelism. we laid out the markings many times over and measured just as much to make sure the scribes were close, then center punched, center drilled, then used the shorter machine screw drill bits with a tap block to ensure perpendicular holes.. lots of work!

All in all, would you say that flat plate makes a good base for a DIY mill, or was it more effort than you expected?

Do you have any pics of your Z axis mounted on to the X-Y? In video of the X-Y in action, it looks like the whole assembly is upside down - unless the Y-axis really is on top?

hi digits. will be posting up some conceptual drawings and a prototype (on a small scale) of a 3-axis post adjustment design shortly. we'll be using 3" square cross-seciton 80/20 doubled-up side by side as the column and will be bracing that using our post-adjusting "thing" to finitely adjust for tramming and squaring true.

re: y-axis. yes, it's on top - the shorter table of the two.

happy new year everyone!

Is that cold roll steel that the guides is mounted to? Has it been surfaced? You might look into getting some tooling plate just to avoid pulling those rails out of true.
