Fork drilling - recommendations?

Borrow a drill with the correct sized bit for the brake, measure the middle point and then drill the hole.
Next measure the size of the allen key bolt and use a slightly larger drill bit to make the hole bigger, until it the bolt fits snug.
Its not that hard if you got access to the tools (which I think is the problem?) just time consuming to get precise.
I've been riding DIY for ages and everything is all good.
But for peace of mind paying £5 is probably worth it.
Good luck with finding a place anyways!
Cheers for the advice. Repped.
