One advantage of DIY is you can make stuff no respectable professional craftsman would, unless you offered a lot of cash and he still wouldn't sign it. :haha:

Pass.

On both.

I find this hard to believe, no splitting and I didn't see drilled pilot holes. I guess it's like the 2x4 through a phone pole from a hurricane. I suspect the "nails" have to be fresh, plus the right phase of the moon and weight of the jockey.

That is cool.

Easy to drill out if one is defective, but hard to know whether one is defective, before or after use. I would expect the relative hardness of the woods to matter. Beech is fairly hard, and "compressed beech" is probably harder. If there's any other treatment/infusion to keep it compressed, it would be even harder (and may compensate for defects in the wood grain).


Not sure I'd trust it as the sole fastener for the use shown in the video (fasten 2x4 as table leg, fasten corners of a bedframe), but I probably wouldn't trust a metal brad for that either. To keep a real joint from slipping, though, it ought to work fine.

Interesting concept.

It's basically dowel joinery, without the glue. But the glue doesn't matter if the "lignin welding" actually does bond between the wooden nail and surrounding wood like they claim. HM is right, though, that it's not going to make a very strong joint all by itself.

I can see it being used to nail decking down. Gravity is holding those boards in place anyway and the wooden nails just keep them from shifting.

Here is the technical data they offer for the strength of their LignaLoc wooden nails. I'm not smart enough to understand what that means. I think shear strength is probably the most important value. They talk about "Shear resistance" being 362 Newtons for the wooden LignoLoc nails. When I look up values for screws to see if they compare, I found this one reference that talks about Simpson screws having "fastener allowable steel strength" in shear of 800 lbf. One lbf is 4.45N, so the steel screws have 3,560 N of shear strength vs. 362 N for the wooden nails.

So steel is ten times stronger than wood.

But maybe you don't need all that strength for everything you make.

Very useful if you're sneaking a deck through airport security.

"Sir, are you hiding something in your pants?"

"Just my deck."

Mama said, if you're going to have vices make sure they are clean ones.

I like. It's very ornate, of course, and I would be afraid to really whale on that little anvil surface at the front by the clamp. But it's perfect for smaller more precise tasks.

Get out of my head.

xoxoxoBruce 08-18-2018 07:58 AM

Tricky case...


BigV 08-18-2018 10:18 AM

Hell no. A thousand times no.

The butterfly is pretty.

If you're going to fill in the voids with resin, why not be honest and make it visible.
