Setting a start point.

Please tell me you did this to a not so expensive machine and not a VMC because id cry if even so much as a spot drill hit my table by so much as 1 micron...lol.
What your saying is a good way of doing it if you dont want to be setting up everytime you take a vice on and off the machine but constantly working in the same area of the machine will wear the guides down over time while the rest of the guides are nice and new.

I take it you didnt read anything into the part that said " 25mm spacing 6 initialy" i should have elaborated i know but that was going to be in another post and i have a 20mm sacrificial bed on my machine which i was also going to put in the same post, i didnt want to put a huge paragraph on the post confusing anyone but you are quite right and i cut from all over the place on my machine because i know where all the spaced out holes are lol
