What would you say to me replacing the Bob's Knobs adjustment screws on my C-11 with Allen head screws? I have been wanting to do this because of the difficulty in turning the screw heads in small increments when very tight. Like Eddgie said in his collimation guide, these screws are not head bolts for a 454 CID Chevy V-8. So I'm aware how tight I should go with these screws in getting collimation adjusted. Given the extra torque available with the lever arm of the Allen wrench, I would need to be sensitive to the maximum force to be applied. The advantage would be in seeing small rotation angles as the screws are adjusted.
What do you-all think? Has anyone done this? If so how has it turned out?
