I had so much fun with the last guessing game that I couldn't wait until tomorrow to start another. I'll go easy on you folks this time. No name. Just tell me what it does.  |

Stumped but, I see that it is an adjustable piece. Has a knurled finger piece and a allen set screw. Are those roller barrings in the hole?

Okay, this one I've got!! My husband is a machinist, so when I showed the photo to him, he went into the garage and brought me in about eight of these tools! This is a depth adjustable tool for countersinking holes for flat head rivets, mainly used in the aircraft industry. Jean

I think motor homes have rivets too, so I'll bet they use them at Don's old job too!

Ah darn. I thought this would run for at least a couple days. You got it Jean.
It's also used with counterbores and drills. I'll post a couple more pics to show how it's adjusted, and how it works.
GR, the knurled nut just locks the adjustment, and the set screw is loosened to take it apart for maintenance.
Jean, PM me your address. I'll get a box of slabs out to you in a couple days.

Here's eight more of them, and another tool used to help with installation.  Don, this question is for you - Do you know the name of the tool, and how to use it? I'm sure you do... Jean |

No, but i do know how to use it. The Cleco pliers were going to be my next contest, but now that I see them on the right of your pic, I'll skip those.
Pics coming up.

As Jean said, this tool is for countersinking. Also for counterboring and drilling where depth is critical. First pic shows the tool with the knurled nut backed off. The top half of this tool has a strong spring in it. By sliding the top half back towards the knurled nut, it exposes 2 rows of teeth. Depth can be adjusted by turning the bottom piece. As I remember, each tooth will adjust the tool in or out 1/1000 of an inch. Tool with toothed parts wedged apart.  One of several sizes of countersinks which screw into this tool.  I have more sizes in my tool box, + counterbores and drills to fit it. Once the proper bit or countersink is screwed into the end on the left in the pic, The tool is either mounted in a drill press or hand drill. Depth adjustments are made using a scrap setup piece. The spinning shaft with bit attached is also spring loaded. Press down to drill or countersink. when you let up, the spring lifts the bit above the work surface. |

Hey Jean, does your husband have any of these clamps for his pliers ? I have about a dozen of these, and a .50 Caliber ammo can full of the rivet hole clamps in sizes from 1/16" up to 1/4" in various lengths.  |

Don, I just saw the last photo, and showed it to my husband. He said no, he says he's seen them before, but has never owned any. Jean
