Post by typical.me on Jul 23^rd, 2005, 12:41pm

But something like this will do the job.

I assume the post will not be in contact with the ground?
Also if possible/practical the make sure that on top of the post you put a chamfer to allow water to run off. ;D

heeelllooo mick and welcome

first thoughts why do you need 4by4 if its attached to a wall
or is the wall only part hight!!!!![eg not a house wall]

if i had a wall to work to i would attach 3by2 treated horizontaly along the wall to attach the pugula to

ok read it more carfully would still dispence with the post and attach whatever horizontal members to the wall

of course if it effects simetry best keep the women happy ;D ;)

First of all, thanx for all your replys, good to know you can get "proper replys" on this site without feeling patronised!!
Big_all, reason im using 4x4 on house side is to keep the pergola looking looking "in sync" with the other 3 uprights. Take your point, but it is really for the overall look as opposed to any structural consideration.
once again thanx

If it was me personally mate i wouldnt put big bolts like that into my wall shaking the hell out of it when you drill.

If my house was in as bad a state as that I'd be outside of it whenever there was a slight breeze wafting against it.

Mick be careful if you are planning to machine tanalised timber, it is full of arsenic and chromium, wear a good mask and don't burn the waste it gives off the arsenic as a gas and concentrates the rest in the ash.

The only thing I would add about bolting the post is that if the post is going near the edge of a wall you could break the face off the brick on the adjoining wall if you used too big a fixing

That page opened as Page cannot be displayed then I refreshed the page and it showed up correctly.

I've fixed 3" fence posts to a wall using frame fixers similar to these
For a 4" fence post I would drill a clearance hole 1" deep beore knocking the fixers in.
If wanted the hole could then be plugged.

6mm x 150mm screws, 2 rawlplugs in the wall.. easy as, not to much damage to wall, good holding power. Done this recently, excellent result and cost effective. I also counterbored and plugged. As for the top, cut it at 20 degrees or so for "run off" and re-treat the cut end.
