ohh interesting! then the middle of each picket can be the same distance from the rail. so that side looks consistent too. thanks for your reply!
i might try that. (after all this is only like 4 posts length on this side easy to pop down!)
Happy fencing!
thanks! trying the parallel to ground idea.

Keeping the pickets vertical like that looks tidy
Now you're cookin
thanks!
Damn man you’re giving me the confidence to take on my fencing project.
thanks! go for it!
Dude great job so far. These things are difficult the first few times. Good going!
thanks for the kindness!
I'd say make it so it looks good to you as long as it'll stay upright!
For the run post to post are you referring to keeping the fence boards level? If so you should be able to lift the boards up to account for grade. Just don't go past your bottom support.
If your terrain is irregular along a given panel, you might have to straighten it out a bit so you get level tops without ground interference at bottom anywhere.
If you have two opposing slopes forming a ‘V’ (valley)… well, theoretically that join is possible. :)
thanks! trying this for a bit now that i took the other parts down. bottom gap i am thinking may be a slight too big but i need to landscape around anyway too. for dogs plants etc.

My only comment is I want the top rail horizontal to resist wind load at the top. I like this design, with the top rail being a cap, that protects the endgrain of the pickets. I'm not sure about putting the bottom rail in the dirt, however.

gotcha. thanks!
