ok a up date
after prizing my son out of bed and then 10 min's later off his computer we made some progress
and did some work in the garage on the CNC machine

and here is the images of today's progress on the x-axis

we first (me) with the aid of pritt stick glued the printed templates to the 75x75 angle and then centre punched it, as image 1

after some choice words we finished and he went back to his computer, great I can get some work done (bless him, dad your drill is much better than the drill at school it would take hours to drill one hole, and we did 16 in 11/29 poor me)

But it was worth it just to see a smile on his little face

any way sitting down and having a coffee i thought how am I going to get two rail square?

this is what I came up with
