Yes you need one, about 12 degrees initial (about 34 to 36 degrees total), and start about 1 1/2 turns out...but I'm only guessing.
So I'm trying to understand, you deleted your question because you didn't get a quick response? Sometimes the response can take awhile. I have more than once started a thread and have not heard from anyone over a period of time, be it hours or days. So I would just BTT or ask again. I have been ribbed, called out and what ever you want to call it. I believe you withdrew your question to quickly and should have posted again. When you see a thread with only a period on it, the first response is ? I get it work can get in the way, but you gave up to early and my stupid GIF was only meant out of fun, not to insult you. As for thick skin, it doesn't hurt to have it when your here.
Darin, I would say that most everyone on here stands ready to offer any serious help you may need, not just to ridicule. Often a little light hearted ribbing may accompany the advise but that’s to be expected with any gathering of knuckleheads. I for one just thought that you inadvertently hit the post button before you got your question typed in and was waiting for your return. Sent from my iPad using The H.A.M.B. mobile app
