Having a go with F360....

Ok, back to this task, nearly ready to get cutting now :)



My thoughts are to fix the waste strips down to table,
set plate square to axes,
clamp plate on top,
mill the slot
drill the three holes tapping size through
drill the part holes to clearance size
tap the holes in the scrap and bolt part down
remove clamps
mill the two large holes
chamfer
mill the outer profile
flip over and bolt down
mill slots
clamp part again
remove bolts and counterbore three holes.

I think that maintains accuracy between the slot/holes and the two big holes??

I could maybe add two extra holes between the three bolts for 6mm dowels if needed?

The bottom plate will be easier as i only have to drill the three bolt holes and maybe dowel holes and then clamp down using the same offsets for the part.
