I want to build a wooden palisade fence, what is the best way of constructing it and attaching the rails to the posts? The fence needs to be 1.5m high. What size posts, rails and pales do i need?

thanks

Is the fence you want build the same as this (bottom of page)
fence ?

If so, the posts are 75mm x 75mm and both rails and uprights are 75mm x 19mm.
The rails are machined out to a depth of 19mm to accept the rails and there is 1.8 metres between posts.
You should be able to buy them in ready made pressure treated sections.

The fence will need to be quite sturdy as it will be in a school. This is the spec

posts 100 x 150mm <to allow for the 50mm to be machined out
rails 100 x 50mm
pales 75 x 25mm

Posts at 2.5m centres, 3 rails, pales at 75mm centres with rounded tops. The posts are machined out 50mm to accept the rails. What do you think? do you think the pales should be wider? is the post to big? Is the 100mm wide recess wide enough to take two rails and secured with coach bolts.

Seems alright.
The only thing I would say is the posts might be better at 1.8metre centres.
If you have been given a spec. then it is probably not open to discussion any way.

I have to disagree here

This spec is what I would use at a school (and have done.see http://www.dcgardens.co.uk/services.htm. click the fifth from the left picture)

Posts. 1.8m x 100 x 100 round top planed all round Morticed 2x
posts at 3m centres
Standard arriss rails, planed all round.
75mm x 25mm x 1m pales, round top planed all round

Dont forget to allow for end posts(which are only moritced half way through) and corner posts if necessary.

Set the first post, then use arris rails to get the distance for the next. set arriss rails into posts as you go. Nail up at the end.
I use a pale as a spacer. (i.e. 75mm pale,75mm space,75mm pale etc.etc.)

Hope this helps

this is what i have put together please tell me what you think.

does the post need to be wider, as the 100mm doesnt seem enough for the two rails to sit as it just leaves 50mm each.

50mm is enough - remember that with two rails, the joints should occur on alternating posts - so, one post 1 the bottom rail is jointed but the top rail goes through, then on post 2, the top rail is jointed and the bottom rail goes through, Try to avoid having both rails jointed on the same post.

The posts will be installed to a depth of 600mm, in concrete. How much concrete? I was thinking 200mm surround? Is that ok?

If you have good, firm ground, then there's no point in removing large quantities to be replaced with expensive concrete. Think it through - no matter how much concrete you use, it eventually has to be constrained by the ground itself, and if that ground is firm, then 100mm all around the posts would be adequate.

If the ground is suspect, then extra concrete support might be justified, but you have to bear in mind that big dollops of concrete create their own problems of instability.
