Boring hole vertically in post
Hello all,,
I am looking at upgrading my current fence to something a bit nicer. At the moment it consists of ~50mm diameter posts with chain link in-between, about 1m high. These posts are concreted into a slab (and I assume lower than the slab as well), so digging them out will be hard.
What I am looking at is getting a 90x90x1800 post and somehow boring out a 50x1000mm hole from the center of it, so I can place these posts over the top of the existing ones, then then just bolt through.
Does anyone know how i could do this and get a straight hole, or a place in Adelaide that might have the equipment to do this?
Cheers

It might be easier to get two 50 x 100 s and cut a 1m channel that will fit you existing posts in one end and then bolt these over the existing posts. Alternatively get the 100 x 100 posts and cut them up the middle and then do as the above which will give a better match at the join.

If the existing posts are 50mm steel tube, you could cut them off about 200 above the ground and use them as post anchors.
then you would only have to bore about 180mm into the end of your new postsregards from Alberta, Canada

Yes cut them off is even better.

I would cut them off flush with the slab, then start fresh - bolt brackets to hold new posts to the slab....

There will be definitely be one gate (about 1000 wide), but that will be attached to the house wall so will have lots of support there. The other gate(s), if I do them, will have some wheels on the bottom to reduce the load off the uprights.
Using 90x90 uprights with decking planks going across, spanning ~1.6m.

Digging out the posts may not be as hard as you think once you get stuck into it - a spike and post hole shovel does the job for me. Alternatively maybe hire a digger for that bit... Might open up more options for post placement and/or require fewer posts.

Decking planks going across, spanning 1.6 m?
Do you mean just nailing them to the 90x90 uprights in a horizontal way, one on top of the other?
Or perhaps an upper and lower plank to which you will fix something like colourbond or similar in a vertical fashion?
