Thx Doob, Ive done a bit for myself before (not the gates), cut the holes with a mag drill (see attached pic).  Im at the scoping the job phase, its a straight 100m run this time for myself again and trying to see if it's worth the effort or just buy in and weld on site.  Its a soulless task drilling 500 holes and grinding 100 post tops☹️.  What do u think it would cost in materials..ball park? Appreciate the feedback!

It's only a souless task if you don't have the right tools. Mag drill is great if you have a big metal bench you can site it on, and also tack some end stops/side quides so that you can drill every first hole, then change to every second hole etc. You'd really want a coolant system too so it gets complicated and a fly press and punch starts to look like a good idea.

 

For grinding the tops, get yourself a firm vented backing pad and some ceramic fibre discs, 36 grit. Clean steel just melts away, they are controllable and 'soft' allowing you to radius easily. And they cut cold too, not much heat. Basically as they wear, the grain fractures exposing a new sharp edge. The ultimate is a wall mounted grinder with a rest plate at the font.

Just make a jig to slide post through to drill all holes in one pass.

Have used fabrication shop  to punch holes but posts have come back bent like a banana.
