So I have an auger and I’m digging holes tomorrow. My questions are…how do I go about making the fence line straight and should I go with metal posts or wood posts.
For the first I was thinking some combination of string and stakes
For the second I’m leaning towards wood for the simple reason that the vast majority of the posts are already wood and I’m not replacing them.
I think that’s the way it’s traditionally done. Stake out the ends, string, stake the middle, repeat as needed.
Dont forget a level to help keep the posts true.
Freakin’ lasers!
Oh so opinion, I have a 6 inch auger and an 8 inch auger. Which would be better for 4in fence posts? I figure 6 would be easier to fill the hole but 8 would probably end up more secure.
I’m not using concrete, dirt and gravel
A long piece of string and a level. String it between the two end posts make sure its level and follow the string as a guide…
A third of the fences hight (for the posts should be buried and cemented)
oh and everyone knows, but it never hurts to say
measure twice cut once…
p.s. 6 inch for a 4x4 should be just fine. The cement and the third buried should be more than strong enough for just about anything but an act of god…
Except that hes not using concrete.
well than… just saying its fun to mix cement… come on all cool kids are doing it and it makes posts strong; like andre the giant strong. one third buried should still be fine, but come on there’s the a wheelbarrow and everything 
I would say stick with the wood to keep it consistent. Unless there is a reason locally to go metal (like high wind), but that would mean going concrete also. 6" might also be a tight fit (a 4x4 is 5" diagonally) so you may need the extra space to pack in the gravel and dirt well.
I would start by staking off and running your fenceline. Next measure off and place a stake at the center of where each post is to be set. You should check your local code to see how deep “the man” says should be buried.
After all the holes are dug I would reset the line above the holes at the point where one side will set (this will allow you to keep them all square to each other). Then if you are really worried about spacing run another line for each post perpendicular to the main line so you have the exact point where it should set to be square and spaced to each other.
Set the one end post first or use the existing post and run a line to the other end post and use the line to make sure they are at the same height. Then you can use the line to set all the other posts to the same height. Attach furring strips to the posts at a right angle toward the top of the post. Then attach to a stake in the ground and adjust the point where it is fastened to plumb it up. After they are set, just fill the holes.
The most important part is the posts. Get them right and the rest is smooth sailing.
Another plus for metal poles (I would still go with wood so everything matches) is that they won’t warp over the years (not to mention rotting) and bend your fence out of true.
OTOH, if you spent more time destroying your enemies, you wouldn’t need a fence. 
Do you have a newsletter and are you taking subscriptions?
LOL, yeah. When I read that I just nodded and said to myself “That’s so our Badger.” Awesome.
Do they make fence slats out of Kevlar?
Perhaps you could build it out of those concrete tiles they made on Mythbusters?
I recommend two critical things for installing a wood fence: A post holer and wood.
What is a post holer? You dig holes. For posts. Wood is secondary but critical.
I had an auger for today. SUCKED. Got all of 1 hole done, 2 sorta done. Absolute waste of time and money. And I damn near broke my wrist, slammed it into my stomach and thigh a few times, absolute crap.
Terrible day. Terrible.
