2957 Star drills. Almost everyone will recognize these. Used to bash holes in masonry. Is there some trick here?

I second the star drills used in mining as well in the early days for boring blasting holes in the stope face.

Masonry and stone. Funny you should take umbrage with them I have tried a few times to buy some because mine have all gone the way of the dinosaur. The big box hardware stores don't seem to have them, and only the older people working there even know what they are. Maybe in another generation or two nobody will know what they are.

You won't find them at the Home DESPOT, but you will at any good concrete yard or full-fledged builder's supply.
Although there are easier ways to make MOST holes, there always comes a time when a star drill is the best tool. It's most aggravating, though, in a vertical 'down' hole. You'll need air or water if you drill that direction.

I've had good luck finding new "antique tools" through Amazon and affiliates, decent prices too. See:
(Amazon.com product link shortened)
or for different sizes:

There just doesn't seem to be enough volume on stuff like this for brick and mortar stores to consider stocking them. Try finding a new Brush Scythe, Cross-cut Saw... locally, at any price...

What..you want some star drills? Ive got a shit load of them
And I think Ive still got a Black and Decker Industrial Electric Masonary Drill motor that uses star drills, unless it was in the van when they cleaned it out.
Interested in them? Ill go look in the morning if you are.

No trick, I had posted one years ago but someone just sent in these photos and I decided to go ahead post them again.

Well... there IS a trick... to using them. One doesn't 'bash' holes in masonry, if using them properly. One 'drills' holes. Neat, clean, and with a minimum of spalling on the back-side, if penetrating.
You don't just hold 'em in place and whack with a hand-sledge. You rotate them slowly while tapping (albiet with a heavy hammer and some authority!).

2956 Let me make a wild guess here. This is a chainwheel from a bicycle, made special by being from the Wright brother's shop.

Yes, it's a sprocket from a bicycle but I don't think it's related to the Wright Brothers. I posted it because I hadn't seen one recently and thought it looked interesting.

anything but straight line type drive, so my guess it for turning square shank drill bits
Nope, it doesn't use drill bits

You're correct that it's a handle for something.

Is 2958 a bird call? Apply a little powdered rosin, put the two parts together, and twist.

2956 looks like a bicycle chainwheel. The small hole between the Y and T is to bolt the chainwheel to the crank, and the axle of the crankset passes through the large hole in the center.
2957 is clearly a set of star drills (chisels for drilling holes in concrete or rock).

if the crank is a cast/forged item (an Ashtabula crank?) it's just a boss on the casting, not a bolt, that goes through that hole, to drive the wheel (friction on the center hole is NOT going to support the required torque).

#2954: Notice that each of the numbers 1-6 appears equally often.
Since this (proposed) die has 12 sides, one side would land up.
I offer the "guess" that it simulates the rolling of 3 dice, such as would be used in the gambling game "Chuck-A-Luck"--popular at carnival's and casino's. Basically, in that game, one bets a chip on a number 1-6, and get a chip back for each time the number is rolled (among the 3 dice), and loses their chip if the number is not rolled. Seems fair enough, huh? Itcan be shown thatit's not.
The fact that there are duplicate numbers on every outcome on this die, gives the house a decided advantage in the game. When the outcome of the dice consists of three different numbers, the game is "fair" (no house advantage). Every outcome on this die gives the house the advantage. This fact is not obvious (which is why it's a "sneaky" game).
So, my long-winded guess is that it'sa fancy die! : )

Maybe the maker of the wooden one didn't want to pay $450?

2953: It looks like something long is being twisted by crank action. The stationary part is probably a handle... maybe a crank for raising/lowering louvers or an awning?
2958: These could be grease applicators. Fill with grease, insert the wood bit to push the grease into the bearing.
