What is it? Set 507

No ideas on any of the others

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

2957 -- Mason's star drills (I still use these things)

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

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.

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!).

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.

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:

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...

No luck yet on the wooden piece with numbers, the rest of the answers have been posted here:

I finally figured out my html problem so the answer link should work better than in previous weeks.

What..you want some star drills? Ive got a s*it 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.
