Decking Advice

[phil p]

Hi,

Can anyone advise.

I'm starting a deck for a friend tomorrow and initially thought it was just a normal rectangular one, however she now wants one corner on a 45 degree angle where it meets a path and I'm a little unsure how to do this.

How should I make the frame?

Would it be best just to make a rectangular one and draw a diagonal 45 degree line, dismantle it and make the cuts?

I'm also assuming the angle of cut for this would be 22.5?

As you can tell I haven't really got that much logic on this so any advice or tips would be greatly appreciated.

Regards
Phil

Yes, the mating parts will be 22.5. It's a very simple job to do but difficult to explain in words, so the easiest way for you if you are unsure is make the frame up as you say, then measure equal distances from the corner you want to splay along the 90 degree corner. Draw a line across on the two marks, then a mark at 22.5 from the furthest points in the opposite direction to the datum mark. Cut these, making sure you square the perpendicular line to cut to. You then measure between the longest points and cut a piece to this length with a 22.5 angle on each end, or simply drop a piece of timber on top and mark it with a pencil at each end. Nail this piece to the frame, then put in any more joists at the appropriate centres, which will be angled 45 degrees at one end.

Hope you understand that.

Could be worth doing a scaled drawing I suppose.

I have done 2 like that it's quite simple make a square and check the diagonals to be sure it's square and mark the cut its not worth trying to work out the lengths.
The ones I did we did a two plank border then ran the rest diagonally to meet in the middle of the diagonal from the middle of the cut corner.
I will take a picture that will explain it better.

Decking advice? Get the first punch in if you can. Oh, that decking ... use pavers instead, not so deadly in winter. :wink:

Sorry, I'll leave you to it. :lol:

Thanks lads for the info,

I was going to start today however Ive been rained off, however I think Ive already dropped a clanger before I start.

I went and ordered kiln dried 4 x 2 for the frame and just found out it's mainly for internal use.

Will this have any dramatic effect on the deck, ie warping, splitting etc?

Don't fancy the hassle for replacing if possible.

Would it still be O.K. to use it?

Kiln dried C16 or C24 is for indoor use, joists and roof timbers etc. Tanalised C16 and C24 is the external equivalent and will last longer. It's the same timber whether treated or not but untreated won't last very long in the garden. You would also be advised to check span tables for the correct support centres for the size and type of timber you use.
