Hello all, using a 10 ft. fence post as a flag pole. how do I stabilize it until the concrete sets? also, how much concrete is needed? will a 80 lb bag suffice? Thanks

2 angled braces (2x4s) down to the ground, The amount of concrete depends on the size of hole .

Drive 3 pegs in the dirt equidistant in a circle and tie a string off from about 5-6 ft. up on the post to those pegs with a clove hitch knot or a improved quick release clove hitch. The tension on each is quickly adjustable to plumb the post.








Given the post size + hole diameter and depth Neal will calculate the concrete needed.:vs_laugh:

if you were using locust or suitable wood mtl, conc collar's all you need,,, set the post & fill w/sand up to w/in 8" of grade,,, when the post rots, much easier to just hammer off the collar rather'n bust out a hole full of conc,,, use stiff conc & you won't need to stabilize it

If you want something Bad to put your posts in with, use this Sika foam. Set your post in the hole, stanchion it off, follow the directions on the package and in 10 minutes you won't move the post. https://www.homedepot.com/p/Sika-33-fl-oz-Fence-Post-Mix-7116170/300934597
