why you shouldn't use a vice to press in wheel studs
I was just saying "this vice could probably take this sort of load every day for a hundred years"... and then it proved otherwise.

The tradditional way is to pull them in with a nut and suitable packing spacers.

A piece of conduit and a couple of washers does the job nicely.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

I plan to use the other traditional method for the rest, i.e. pay a man to do them when I get a garage to press the hubs onto the uprights...

I did the exact same thing not too long ago when replacing a U/J in my Defender 90 front propshaft....
Not sure if it had anything to do with the fact I was hanging off the end of a 4' scaff tube on the tightening arm of the vice?!?

Bit of plastic metal and a couple of cable ties will fix that.........

Hope you got your toes out of the way in time.
Although I'm more concerned about the other items on your desk.

:-) Not my desk... can't answer for either of those items. Toes are fine thanks. The floor isn't quite as flat as it used to be.

Are you sure they're right for the hubs? They really shouldn't be that tight to break a vice. I've usually use a hammer to knock
them in/out and it doesn't need much force.

I reckon that if it's an old vice it's probably stress fractured as the force goes through much the same path every time.
No doubt some metallurgist on here will verify or correct this shortly.
Did something similar on an old vice which had belonged to an uncle. Vice must have been at least 60 years old and had a hard life.

Yeah... good question. The knurl on the studs is 14.3 mm, the holes are 14 mm. Which is quite a bit of interference (12 thou), but as far as I can
tell, that's what everyone does when re-drilling Subaru/Nissan hubs. I suspect this may be because 14.1 or 14.2 mm drill bits are hard to come
by, not because it's ideal.
But it seems just about OK, don't think it will damage the hub?

I have to admit, the only time ive changed studs (both on trailers to be fair) they have just tapped in the first bit and pulled in with the the nut
the last bit when putting the wheel back on.
Seen someone break a vice once before, but he was a bit of a brute, and he had mullered it up on a subframe before wrenching said subframe all over
the shop. Shame, becuase what was a nice record got replaced with the cheap Chinese shite.

4 pairs of ear muffs at hand 
If you were near-by you could pop over and use my 20 tonne press. That should do the job

14.29 apparently, maybe a touch too big. I could get a 14.2 or 14.1 drill easily enough, but I've drilled them at 14 now, not sure there's
any point going to the effort of enlarging them - a hydraulic press will get the studs in easily.
I think it's only worth enlarging if there's a significant risk of damage to the hub from the interference? I've read that 5-20 thou
is acceptable, I'm at 12 so I reckon this is probably OK?

Nah, he's got a vice 'n tools in the computer room!
I used a press for my front studs as the hubs were off and used nuts and spacers for the rears. They were very hard to draw through, IIRC they were
Rally Design studs (Sierra hubs)

Actually, it's a friend's front room - he moved to a house without a garage so his biggest and nicest room is now a workshop complete with
lathe and milling machine. He has an understanding wife. :-)

Finally, got them properly pressed in:
Apparently it took 5 tons to get the studs in, I guess I don't need to worry about them spinning. Lets hope I made them long enough...

You could pick up an adjustable reamer within that range and open them up.

Let's hope you put them in the right holes for your particular application!  I assume the other set of five are for a slightly different PCD?

Yeah, it started life as a BMW 5x120 hub, but there are no lightweight wheels for that fitment. So I milled some new holes at 5x114.3 in order to use
some lovely ultra-lightweight forged magnesium JDM wheels. Definitely the right holes!
