Replacing my vise with these!

[MasterMaker]

Unfortunately I haven't gotten a chance to use them yet as there is always something that needs to be made in the vise and thus preventing its removal.

Kind of utilitarian but I think they will prove useful. I made a whole bunch of them(several of each type) and the low profile ones protrude above the mill table less than 10 mm, the tallest are a surfacing cut shy of 30 mm.

I think I need to buy a better camera though.

So... What are they?

[J Tiers]

hah....

neat idea. That jaw won't rise up!

Look at the nose of them.... the flap is hinged at bottom, pushed by screws. Tilts down as it moves out to grab.

Biggest problem is that now you have "disclosed" that (used to be a) possibly patentable idea publicly

[TGTool]

Probably not patentable. At the USPO they would probably say it's "obvious to one skilled in the art." And besides, there have been recent articles in Model Engineers' Workshop about low profile clamps like these recently.

Still they're a nice idea and those are a nice execution. Good go.

[J Tiers]

yabbut, he's in Norway.

And, you have not seen what gets patented. Stuff in older patents has been patented...

In any case, a good idea. I may copy it, since it is now in the public domain!

[DR]

Variations of these have been around for years.

The only time I've had occasion to use my factory made versions are when the part to be held is wider than the milling vise opening.

The Chinese obey no international patent rules.......IF he had one.......it will be on sale w 800 watt by weekend.........

Nice job..........

Ahhhh. Gets rid of the ways, so theres no way for the jaw to lift. Nice.

[Black Forest]

I still don't see how they are used.

Explain it slow and in simple words for us dummies!

Yep, and in countless before too. Nice idea, but no patents were harmed in the making of these I assure you!

Black Forrest, they bolt down onto the table using the t-slots, snug up against the work. Then tighten up the horizontal fasteners, this spreads the slot you see in the pics, clamping the work to the table. Using these or eccentric versions, the work size is restricted only by the size of the table as no vice is required; the table IS the vice.

PS It was December edition actually, but 9/10 for memory

What stops the clamp sliding along the Tee slot, apart from the friction grip from the clamping bolt holding it down?

The friction grip from the clamping bolt holding it down

[gwilson]

If those are aluminum,better place a piece of paper in their jaws to keep parts being machined from moving. Maybe they are steel. I can't tell,but the color looks like aluminum. I made some of those in the early 70's.

[jackary]

Pete F if you only have the friction grip clamping axially along the Tee slot the clamping force is limited to this and can move under a heavy cut.
