Ok, loose is a bit strong, but...
I redrilled the hubs on my cf but i screwed up one of the half shafts.
On all the other 3 corners I drilled the hubs so the studs are a really tight press in (beat in with club hammer) fit and drilled the brake drums so the fit nice and snug over the smooth, non spline section of the stud.
On one corner, I drilled the half shaft to the drum size. The studs knock in but they aren't as tight as id like. They may be fine, but if a wheel nut seizes or is over torqued and the stud spins then I'll be in all sorts of trouble.
Redrilling them was alot of work as I had to flat spot the rear face of the half shaft which took forever so I'm wondering if there is another option other than replacing it and trying again. For the same reason, and space reasons, I can't redrill further round.
My only options I can think of are to reduce the size of the hole (I dot punched around the edge which showed a little promise), find some 7/16 studs with a slightly fatter splined section, get new stock studs and hope the splined are more pronounced, or put a flat on the back lip of the stud and a tack weld on the back of the half shaft to stop the stud spinning.
They really aren't that loose, they still have to be knocked in with a hammer, but one smack will do it rather than the repeated smacks the other hubs take. They would be fine to run, I'm just concerned about the slight possibility of them ever spinning if something out the ordinary happens (savage overtightening by tyre shop numpty etc).
Or, have I ruined it 😂
