Well, this starts with me being a bit tight. I hate buying brake disks, especially when they haven't done that many miles, but the car has sat for a while (MX5).
So I thought, having a reasonable size bench mill, and a rotary table, I'd have a go at seeing what could be done with resurfacing the disks.
I've got a pair of scrap 2007 Civic disks I'm practising on, and this is how far I got tonight.
First I checked the rotary table for run out - couldn't detect any with a dial pointer.
I decided first to use a 12mm end mill to take off the outer lip and the inner one - I'll be using a fly cutter for resurfacing, didn't want the lips to add extra stress of collisions.
I wanted to surface first the inside face then use that as the reference for the outside face. At this point I'm actually thinking though, due to haivng a 6" rotary table, I'll actually get an old 4" bearing outer race to pack up the disk when I'm getting onto the outside.
See the results, surprised at the following:
Thickness of disk is uniform when tested with a mic.
My surface finish is too rough. (More RPM's at the fly cutter??)
The cut is not even all the way round - I'm reasonably certain the hub face is well bolted to the rotary table - perhaps the disc was warped??
