pay attention to what redline said so you get your terminology correct (if that's important to you). the clamp sets the helical, you control the offset.
I definitely want to get the terminology correct. Thanks for pointing that out! It seems to me that not using a right helical would be pretty dumb. Why even use a left helical if the target points are going to come unscrewed...seems right would be the only way to go. I understand that back in the day, it use to make a difference, but now a-days, it seems right helical would be the only way to go.
