That's for the great ideas !
So had a little machine time the last few weekends:
track profiles turned up so experimented with forming the right bends etc
it needed a little trimming
End result
the gap between the pads was a little too big so had to readjust the jig

these are the ones I will be going with
they need slightly milling at the front so there is a couple mm tolerance but generally they operate well. still need practice on tig as my welds are shocking: )
