What is the machine???

How about a link to the video?

Not sure this is a link....

SQUARERULE FURNITURE - Making a White Oak Table

Look at about 4 minutes and 20 seconds in.

Incidentally, it's on YouTube

Here’s the link *LINK*

Like Barry said, about 4:20in

This is the machine ...

Derek Cohen (in Perth, Australia)

It is essentially a circular saw with a rise-and-fall table. Part of a combination machine (mainly a table saw). Quite old vintage Japanese iron.

I had a video of it, but the link is no longer working.

Frankly, a bandsaw makes more sense - safer and fuller cut.

Interestingly there seems to be no obvious allowance made in the construction for widthways expansion and contraction of the table top. He attaches it with threaded inserts screwed into the underside of the top and then uses connector bolts and washers through the bearer and into the threaded inserts. This occurs from just before the eleventh minute onwards.

It's possible the holes are oversized through the bearer for the connector bolts to pass through, which should account for movement, but I couldn't specifically make that out as I watched the process. Slainte.

I would have to answer "that machine is scary!".

That was my thought. That 10 or 12" blade out in the open scares me. In one version I don't think it has any sort of guard.

Even with the sliding table, there will be some "corners" left. As much time as these guys spend with chisels and planes I can't imagine it's much more accurate than a bandsaw for cutting the cheeks. Or a tenon jig on a TS. I'm just trying to understand why they have it and not some other system.

How strange! I was blown away when the guy had to tilt the workpiece a bit so that the circular cut would go all the way to the edge of the board.

Maybe uses as homage to his mentor or something....

I really admire Japanese woodworking, but the days when we just assume that if the Japanese use this technique it must be better are long gone. That's how we just into this "Just-in-time" manufacturing fiasco.

Bit of a stretch from JiT to woodworking. I did take a seminar from a Japanese plane maker who was missing two fingers on his strong side from one of those machines that uses two huge chisels to toss out 80% finished plane parts. So yeah, not everything in Japanese shops is safe. Those things are candidates for Chiselstop.

I see nothing wrong with that machine. It is not guarded, but it does not appear that one would need to put one's hands anywhere near it. Most US machinery is about that bad, which is why we have kludges like Sawstop. I mean that in a non combative way. The US TS field (nearest machine) is still cruising on a design that is really old, and has many bad features to which some very clever aftermarket kludges have been added.

Compare the exposure in that tenon machine to something like a jointer with a swing guard, the classic and still sold US design. You can feed you who hand into one of those. 8 inches of basically wood chipper. Rent Fargo for information on use to which such machines can be adapted.

What makes a machine of that type safe to use, is if it is actually used in a way that limits the option to that one safe procedure (assuming it is as safe as it looks). Bad things happen when people are still experimenting as newbies; Push tools to do everything, as often happens with routers and TSs; and the tools have design flaws.
