Question 1

how are the nylon pads attached? do they stay put? are they rigid or soft?

Accepted Answer

There are two fairly strong magnets on both the vice jaw face of the pads, as well as on the upper support overhang. The face retaining 1/4" dia.  magnets are positioned 3.150" apart, and the overhang magnets are 3.95" apart and equal distant from the ends of the jaws. The nylon is fairly hard as you cannot flex these pads by hand. As a compassion, they seem as hard as a frying pan handle. My comment as far as their practical use is that the contact face that bears against the vice jaws is only 7/8" wide, yet, due to the 3/8" additional thickness of the overhang that is above the normal contact faces of the vise jaws, any clamping done on smaller parts above center tends to twist these pads off the vice jaw faces.   Because of the deep ( .205" ) V groves in these jaws, they are really designed to hold round rods of more than 0.3" diameter in horizontal, vertical, and 45 degree positions, and will do fine for that. The upper and lower horizontal face-to-face grip surfaces resulting from the deep central groves are only 1/8" wide. So, not much face area for gripping. Again, these are primarily for grabbing round stock in their v groves, like gun barrels, etc.

Question 2

what vise jaw size do they fit [4"]?

Accepted Answer

The overall length is 4-7/8".  It is held to the jaw with two 1/4" round magnets.  Outside edge to outside edge of magnets is 4-1/8".  So while you're not going to get full contact with a magnet on your jaw, I would still think there would be enough to hold a piece on.  I've used them and they held tight without slipping or marring.

Question 3

Any reason they will not work OK in a 5" vise?

Accepted Answer

They will work FINE on a 5" vise. It is really just a matter of what you intend to clamp. Perfect for gun barrells or anything of similar diameter. Yet, the grooves are too deep to accurately clamp anything under 9/32"  Probably 5/16" is the smallest diameter you can grab--unless you file off some jaw material.

Question 4

What is the dimension of rectangular flat surface that rests against the vice?

Accepted Answer

1/2"X4inches
