Cheap tweak from Virtual Dynamics:

I agree that the equal torqueing of the screws probably is as important as the composition of the screw.

Hi,I looked at the wheeler online and it looks like the lowest setting you can get is 10 lbs,How do you get to the recommended 8 lbs.

It does say 10 ft.-lbs on the ad I recently saw. Rick was using one in the VD video, and he mentioned it goes down to 6 lbs. He uses it to adjust gun stocks on his high end target guns.

Guess I'll find out when I receive the wrench. If 10 ft-lbs is the lowest setting, then 10 ft-lbs it shall be. At least all the screws will be equally torqued.

Apparently this Fat Wrench is offered in a couple of versions. Here is a site where the model shows 5-60 lbs. I don't think the differenc ebetween 8 and 10 lbs. would be that dramatic. Chances are if you manually tightened the screws down it would be more than even the 10 lbs. so you should be fine.

Hope I ordered the right one!
