Thread: How to make this bed?

I reckon I'd laminate the sides out of sheet material & cut it out with a jigsaw.

Hey Cliff, can you get plywood sheets that big?

A normal 2440 x 1220 sheet would be long enough, but probably not wide enough for the side frames of the bed.

Mr Ply & Wood sells bigger than standard sheets of plywood.....

3050 x 1500 mm in 12mm and 18mm thicknesses. The 1500mm wide sheets might be wide enough. It's imported exterior grade hardwood BC ply with exterior grade glue, so would be ideal for your purpose. Last time I needed some oversize ply for a project, I had to order it in as the Brisbane outlet of Mr Ply & Wood doesn't hold it in stock - but it only took a few days to get some up from Sydney at no freight cost on the company's normal re-stock order.

Alternatively, you could laminate the sides using 2440 x 1220 wide ply - maybe 5 layers of 6 mm thick ply to make up each side. To get the height of the sides, you'll need to lay two sheets of ply edge to edge in each layer of the laminate to get enough height for the sides. Just make sure that the edge to edge joins in each layer of the laminate are well staggered through-out the thickness of the laminate.

Hope those ideas are of some use.

Looks like a sheet of 32mm ply. Length won't be an issue, but you might need to squash it a little to fit a 1200 wide sheet.

That is how I'd do it, 2 edge to edge one way, 2 edge to edge at 90° to them & then another 2 edge to edge the same as the first 2.

That makes a big 2440mm square.

Given it's an outdoor bed unlikely to be ply. Looking at the grain pattern in the photo it's all aligned. I would guess this is made from solid timber.

Prep a ply template, glue up solid oak pieces that cover the right areas and rout to shape from template. Wouldn't actually be that much timber and may even be cheaper than trying to do in ply with the amount of waste.

I wouldn't do it in ply , half the grain is going the wrong way.

solid No, it would crack across the short grain.

I would Laminate it ( each side) up around a form with thin long strips , add the laminated horizontal section in with tenons or domino's later .
Im talking 50mm x 3.5mm x ? meters long whatever you like, as long as its straight grained and no knots . clamped around a chipboard egg shaped jig, 4 x 17mm thick = 68mm , clamped with a long steel strap and two pack glue.

That would be the strongest way . Its not going to look exactly the same as the picture unless its covered on the sides later . whats in the picture looks like birch ply .

Why is it unlikely to be ply for outdoor furniture? Marine ply will have no problems standing up to the weather. It's definitely NOT solid timber; there's short grain everywhere which would very quickly break. If you look closely at the ends you can see light and dark layers, which is a dead give away to it being ply.

Where is the grain the wrong way in ply? Structurally, it makes no difference because ply is cross layered.

Ply is not as good as a beam , by itself , as a solid piece of wood .

Ply is great as a brace , as in a fixed panel nailed and glued into place , but not as good as a shelf in a bookcase compared to solid timber .

You know that half the grain is going at 90 degrees to the rest of the lamination's EJ

In that bed design , it doesn't really matter because there is enough wood grain going in the right direction to hold the guy up , probably even a friend at the same time . but half of that ply , which it looks to be , is going at 90 degree's to the beam he's lying on . it's a weakness .

Laminated thin strips maybe a fair bit more work , but it would be the best way to build it I think. You could probably sit 12 big forum members in there at the same time , some on top ? no problems . you couldn't do that on the ply one .

Rob,
Correct....plywood has little strength gained from the cross grain oriented ply sheets as you load the beam .... Like splitting kindling compared to chopping a tree down.
Maybe Random Oriented Strand Board would be another option?

A plywood beam is like this picture, good and bad ...

Cheers,
Peter

blimey, would give a whole new meaning to 'having a roll in the hay'

fair go Ive got a dirty mind.
