So after doing TONS of reading online, watching tons of videos.... There does not seem to be any consensus on what is the right way to set a fence post. Put gravel at the bottom of the hole, don't put gravel at the bottom of the hole, fill the hole with cement, don't fill the hole with cement... If you fill the hole with cement, make sure the cement is proud of the ground and shaped so water runs off it, or cover the cement with a few inches of dirt so you don't see the cement. I can find 100 posts for any given method with people saying the 20 years later my fence is perfect! So is there really a definitive ""best" or "right" way. It sort of seems like if you do a "good" job with any of the potential methods you end up with a good fence?

I want to insert 1/2" into a newel post. I want it to be permanent. What type of adhesive should I use to make sure the lag bolt will not come off?
