Thanks Brett !

A very interesting video and a very useful set of clamps !

I like his mill !

Only odd thing to me was that the jaws are not keyed on in some way as all the downward clamping force is taken by a couple of small cross head screws?

Nice horizontal borer and I like the packing blocks he was using with their tapped holes so you can get the clamp stud right up close to the work

Very nice work, Solid looking clamps.

Beautifully 'sculpted' ... and much larger than I imagined, from the opening shots.

Very impressive.

MichaelG.

love them.

but question about it from someone who knows little about milling having only done very basic bits on one.

i assume he used cutter to start bolt hole then finished with drill bit as cutter less likely to wander giving better accuracy?

.

Correct, Mick

The side loads on the drill would be appalling, otherwise.

MichaelG.

Wouldn't mind his mill.

The idea is entirely scalable, and is a good one.

Jason, the jaws are held on with two screws that look to be one size smaller than the main clamp. The vertical clamp load, neglecting friction, could then shear the two jaw screws. As the area of the jaw screws is about 20% greater than the clamp screw, it's theoretically possible to shear the screws when clamping down. In practice, because friction exists, this won't be likely. I agree a key would be useful, I wouldn't argue against it - based purely on all the un-necessary brochure machining already being put on the clamps, so adding a key would be a negligible increase in machining time. But the key is not strictly needed.

I would love a set of clamps like this albeit a bit smaller. The question is, can I afford the time it would take to make them while working at my normally relaxed "speed"?

Nice bit of workmanship there. When I saw the first picture I thought how did he manage the large radius? Good to see the techniques used and the finished job. Now all I need is an enormous bed mill that cuts steel like butter.....

I think there's a few of caught on the horns of that dilemma.

Of course, if all you really gotta do is scrawl a few chalk lines on a block, chuck it in the mill and turn on, I dunno what all this engineering mystique is about...

Good link Brett, thanks. I would have liked to see what the mill he used looked liked though, seems to be a monster! Also, the finish straight off the machine didn’t look particularly good on those clamps but then in the final shots they looked great? The Vee blocks from rail track video is also pretty good.

I saw a tape measure and one time a vernier but the chalk intrigued me, All this careful marking out seems a waste of time. He did use blocking in the table grooves and that machine was quite powerful it seems.

I think the chalk was for the camera, I one shot you can see he has blued a line and scribed onto that.

You can see a bit more of his borer in this video. Or if you have 25,000 Euros to spare this is the one for you!

cheers for that.

a good day as learnt something new.

Fabulous machine, in a great workspace

< drool >

But I'm a little surprised that he hasn't discovered the merits of a decent ratchet & flank-drive sockets.

MichaelG.

I was even more surprised to see him brush swarf away with his bare hands, is this man a god?

Nice clamps though, although his machining skils and tooling means that he probably made them, just because he could, I'm somewhat envious.

Nice clamps. He certainly knows how to use that vertical boring machine. I guess this is the same guy that made that very large vice I saw on You Tube. not a lot of activity going on in that factory, maybe he was working in his own time on a weekend maybe?

Concur, great vid, great component finish.
