New assortmentsystainer for Domino!

In the UK this is called blockboard.

Lumber core plywood was much more common in the states decades ago but I actually saw a few sheets in a Home Depot once. (Once out of hundreds of trips)

It’s a great material combining the best features of both solid wood and plywood. I have some mid-century furniture made with walnut veneer lumbercore. Drexel Declaration

Thanks for all the different names of these boards. I wish we could source it here. I tried that link for the furniture but it didn't work. I think I first saw or heard about this material in Germany by way of an art show being installed. But that was probably more than two decades ago I think.

It's basically the original plywood (one core layer).

It was an often used material in the beginning of furniture mass-production but has been mostly displaced by (laminated or not) particle boards (inferior in some aspects, like durability, but way cheaper to produce) and multiplex (better form stability as of no twisting).

So I keep bringing this up in different places but what is the deal with no one offering a truly engineered hollowcore sheet good? Ikea has the R&D to make this happen. Ironically their packaging material does it on the level of cardboard. And now with nanocellulose wood pulp coming to market they could make it plenty strong enough. Anyhow, it seems ridiculous at this late stage of material science to be stuck with one single sheet good option like plywood. Too bad crowd sourcing is bored with topics like these! Otherwise, someone independent might be able to go for it. Could the plywood lobby be that large and powerful? It's a bit like the formaldehyde issue in plywood. Why is there still only one company (to my knowledge) doing it without this hazardous chemical?

Have you looked at IKEA furniture lately? I am convinced that most of their stuff, at least the bigger wall thicknesses are moving to honeycomb cardboard with melamine coating.

But I am also sure that they will not bring this to the open market, since they will try and user their R&D as competitive advantage...

[member=32478]mcooley[/member] sounds like you’re talking about a hollow core door. True hollow core construction requires the panels to be made in the final use sizes. You can’t cut them down later without loosing the required solid material around the perimeter.

IKEA does make use of hollow core panels in the thicker (like 30mm) panels but they contract for millions of the specifically sized parts to be produced.

And one of the issues with hollow core is the use of fasteners.  I remember reading an article in probably Fine Woodworking a long time ago about the use of hollow core panels in the interior of custom helicopters.  The use of fasteners required that specific cores had to be filled to accept fasteners.  I now that we are talking about simpler products but the concept is the same - fasteners won't attach to air.

While it would be more effort to fill some honeycombs with something that can be screwed into (would take a while longer as one would need to wait for whatever stuff one fills it with to cure) a system which injects through the hole one will need for the fasterer anyway shouldn't be that difficult.

Problem I have with the ikea style honeycomb contraptions is that they seem to be pure throwaway stuff, modification or repair is quite impossible.

I agree, the fastener problem seems easy enough to engineer. I am not aware of any Ikea hollowcore that is here in US for cabinets, furniture and the like. The issue of changing sheet good size does seem like a challenge. But I would think with the aforementioned wood pulp coming to market one could make the sheets cut friendly, i.e. not losing stability in the board with cutting etc. Who knows maybe the nanocellulose wood pulp can result in a solid board but at half the weight of plywood? Time will tell. But as more things are now shipping flat pack it would make sense to start getting rid of the weight.

So question on the assortment kit, what is the purpose of the 36 mm dominoes? There isn't a cutting depth on the tool that easily gets to that number (12mm on one side, 25 on the other?), and it the recommended 15mm depth on the corner side and 28mm on the other seems big enough that you should just throw in a 40 mm domino that we already have. Can someone explain what the purpose of the new, slightly smaller size is for?

On the question of the availability of honeycomb panels- there is a manufacturer: Singcore. http://singcore.com/  they used to sell to individuals, but now it seems you have to be a business.  But, they have some interesting use-cases on the website, from tiny-home walls to large accordian doors.

I have ordered a set of the connectors and hope to have a play with them so that I can be more helpful with questions, but of course here in North America we are behind the introduction curve.

Where I live there are a lot of companies that have the exact same policy. They want to know your VAT number to put on the invoice etc., but when you say you will pay right away, they don't give one iotha what number you give them. It's just that they don't want to deal with consumer protection laws.
