I am considering constructing a roof woodie under my car port. Can anyone tell me what the minimum thickness of the ply should be? Cheers Col

Hi there,i am designing the same sort of training board,and its taking longer than i first thought!.It seems the recomendation is anything above 18mm,it will have enough strength to hold avg weight,hope this helps cheers.

I used 17mm (or 18?) OD plywood & it's fine. OD is 'Outside Defect' which means one side of the ply is a bit knotty. Makes it a little cheaper.

Make sure you use good T nuts. I started using some cheap crap but soon found the bolts strip the thread on the T nut if you over tighten. I got much better quality T nuts from Keable bolts in Nth Melb., although this was about 6 years ago so I can't guarantee they still have the same product.

ply mostly comes in 17mm or 19mm both are good 17mm is cheaper and if you are worried about strength just put in a couple of pine studs to stop flex. I have used 17mm for my wall & roof section no problems.

good advice from robin on the t-nuts get good quality ones. The crappy furniture making ones such as are avliable at bunnings useless and also rust in no time. Nickel plated nuts last longer.
And make sure you drill a 12mm hole for the nuts as any thing smaller will result in dificulty getting the bolts to seat properly.

another tip is to scout around building sites for form wood. This is used to form concrete and is great quality. It is usualy 19m and BLACK ply wood.bits with only a few defects/holes are often discarded.

my # 1 tip is Dont paint your woodie

@Hatman Why not paint?

Hatman pretty much sums it up, but I've found it's either 12mm, 15mm or 18mm that you'll find in places like Bunnings. 15mm is fine providing your supporting structure is solid. If you want to minimise costs - then go with this option. It also depends on what angle you're talking about. Obviously the less steep - the less you need to really worry about thickness of board (generally speaking). We've used in the past 12mm for 15 degree (overhanging) - but with very good supporting structure behind it. If you're building a steep (45 degs or steeper) board and it's using 8x4 sheets - then you'll definitely want 17 or 18mm. We've got 17mm and 18mm at an angle of 70 and 55 degrees - and it doesn't flex at all - even when 90kg+ users pull down on it (we're all cake-eaters here).

I have found that textured paint just wears you hands and shoes, leave that for the real rock,

and normal paint can be a pain, it will either cause you holds to spin on the slick surface or after you tighten down the holds a few times the paint will act like glue! Some of my holds I had to hamer off my old painted woodie as my bodyweight could not dislodge them!! this will all so leave ugly scars on your wall.

Thanks - due to the mix of timbers, I thought a coat of normal paint would be a good idea to provide a neater finish...

Teenuts can be acquired from "Metro Bolts" in Swan St Richmond. Ask for George. He is the man we've been dealing with to buy the supplies for Burnley and understands which teenuts climbers want.

It depends on your ethics. All sorts of woody materials can be "aquired" without major expenditure.

Might want to be a bit careful about how you phrase this conversation.

When I was a boy there weren't many woodies in the 'burbs. There were, however, lots of half pipes.
Half pipes, as it turns out, are made from plywood supported by framing. Now the rumour amongst the skaters was that if one were to wander the streets late at night one could find stacks of formply lying around at building sites.........those skaters sure were an unethical lot!
