Pesky Parker jaw inserts.

[NJ Marty]

I have shot these screws with PB blaster for 2 days and still no luck. I can turn each screw about 1/64" counter and clockwise and that's it. Anyone have any tips on getting these out other than taking it to mechanic friend and have him try impact gun with drive attachment? The other insert is broken and
I am going to the machine shop at work and will ask if I can get a pair made.

Use a hand impact driver and tight fitting, hollow ground bit.

Marty: you can hand drill out the screw heads, take the jaws off and then unscrew the nubs left of the screws out with a pair of vise grips.

did you say that is a Parker vise? i'm used to seeing Parker vise jaws pinned in place so can you show more pictures of the vise?

People hammer on the jaws and then bend the screws. I'd drill them out.

That's a little one, look at the round slide bar.

BB: i did see the open screw so assumed it was a wee one. Marty must be busy shoveling snow so hopefully his power isn't out too.

Marty: you ok?? any full size pictures of the little Parker? also Fretters hand drilled out some jaw screws and showed some great pictures on the Vise Repair 101 thread.

I'd go with the drilling. It saves a lot of farting about. Centre punch, run a small diamaeter drill down and then go in with a bit the diameter of the shank/thread, to the depth of the head. The heads will then literally just fall off else a quick tap will partthem from the shank.

These are several of the photo's DIF is referring to. These are dome head screws, but same method applies for any type of screw. Running the small drill bit down first helps to stop the larger bit snagging and trying to skip out of the slot.

Centre punched:

Screw on the right has had the small drill bit run down to the depth of the head, and the left hand screw has had the full width drill run down to part the head from the shank.

You're then just left with the shanks/nubs when you remove the piece.

Drives,
These jaws are from the Parker 66 I got a few weeks ago, the pictures are in the link below. All is good here, The worst storm humans will ever see as the weather channel made it sound dumped a staggering 2 inches.
I will drill them out like Fretters showed in his post.
