What is it? XLIX

#272 Window Lock #273 A clamp-on sight of some sort. #274 Pinstrip painter? #277 Tee nut

All correct except for 273.

Correct, except on this old camera part the shutter is in front of the iris.

Kinda small, but I suppose you could always call 'em and ask for a bigger picture.

#271 - Something for distilling?

277 isn't drywall - it is the backside of a wood piece that is bolted to something.

The Iris could be a shutter for a color spot or bright lamp - or carbon arc lamp to shut down the volume of light to the subject. The real question is how tough is the item - is it very thin - then camera - if reasonable thick then lamp or a projector (carbon lamp) limiter. or on/off switch.

I have the model type - a professional hand holder - less ink - but in a box the size of a check replacements box - and another one full of various heads.

I planned to pinstripe a model I am doing but got interrupted by excessive work at work....

The heads seem to be the same or like that on the auto one - massive ink supply.

Martin

that is the one I have - nice movie and general site.

I'll use it in book binding and other little tasks.

Iris, not shutter. It's adjustable to control the aperture, not open & shut to control exposure. An iris like this can't be fully closed, for one thing.

Oh how I wish the researchers at work would realise that and stop wrecking them on the furnaces....

Does anyone know why #275 has all that Rube Goldberg clockwork and stuff? Why is it so complicated? (Yes, I know what it is, that's been answered a lot. :-) )

Thanks, Rich

There's also one on one of the lathes where I work. But in the pic #275, the points didn't look like wheels to me, and it doesn't fasten down.

The background is all dark, because the shop is shut down for the night.

But you can see the source of my confusion! :-)

Cheers! Rich

When I was a kid, there was a series of books either by Time-Life or Bell Labs/Disney or something, with all kinds of interesting scientific stuff. In the volume on numbers, there's a cartoon of a guy trying to do long division in Roman numerals. ISTR that after filling up a whole page (like filling up a whole blackboard in a comic strip) the guy gives up. :-)

I said "complete shutter *assembly*". That is shutter blades, timing mechanism *and* iris diaphragm.

The iris is only part of it. Did you bother to look at his latest set of images of that one item from many views? It has the provisions for setting several (quite slow) shutter speeds.

The shutter happens to be open, so what was initially photographed and presented in the puzzle was only the iris diaphragm, but he has the whole shutter assembly there -- except for the lens elements which screw in behind and in front of the iris and shutter.

Enjoy, DoN.

It is definitely not a wall anchor. (although it could be used for one if put into place before assembling the wall! ;-) )

Cheers! Rich

Yep! What you photographed is a steady rest, not a lathe dog. It is intended to have telescoping arms extend out of the three arms shown at 120 degree intervals. The knobs on the end of the arms extend the inner ones to contact the workpiece and support it on center as it rotates.

The lathe dog shown in the puzzle clamps onto the workpiece with the square-headed screw, and a pin from the faceplate fits between the two legs to rotate the workpiece with the spindle while it is supported between centers.

Enjoy, DoN.

Sorry, no I hadn't - I'd only seen the original close-up.

Nice to see a shutter with the original pneumatic remote release.

Is Rube Goldberg an American Heath Robinson?
