What is it? Set 469

You expand it over the surface to be covered to mark the spaces evenly before drilling for rivets.

The tool used to maintain this:

Rivet spacer is correct.

I think this is probably correct but I haven't been able to find another one like it.

Good job, based on the links that were posted by several others it looks like you nailed it.

Correct, it's a rack for rifles and pistols but I don't know if it's rotary.

Never would have guessed it was a drum stick but then I've never heard of a bodhran before. Thanks for the answer and for the links, I'll forward them to the owner of it.

Posting from rec.crafts.metalworking as always:

2726) *This* one I know. It is intended to divide a space equally for rivets for sheet metal (aluminum, titanium) attaching in aircraft construction.

You mark the position for the first and last rivet, and then expand it so the end arms (all arms have a single hole at the free end) are over the first and last holes, and mark the rest through the holes in the other arms. If you need fewer rivets than the full count (twenty in this example), you can use one end and an inner arm over the end holes.

It could be for crimping joins of sheet metal instead. Or it could be for straightening bent pins on integrated circuit packages.

I am puzzled by the lever, however. I would expect it to be for closing the jaws more tightly -- but I think that as it sits, it is for opening them instead. Perhaps it is for separating two sides of an opening of some sort?

2729) Intersting. It sort of looks like a beater for a bodhran (pronounced bo-ran) an Irish frame drum), but it looks rather ornate, and to have been made of ivory. Perhaps for a similar drum in some African culture, instead?

With a bodhran, it is beat alternately with both ends rather rapidly by vibrating the beater back and forth in the hand. But the beater is normally wood in all that I have seen.

I see that the slots are numbered, so each soldier can recover the weapon which was issued to him/her specifically.

Now to post and then see what others have suggested.

Enjoy, DoN.

The previous owner of this one had some African artifacts so it could be from there, the current owner described it as quite heavy and said from its history it could be over 100 years old.

Thanks again to everyone who helped solve some of the items this week, the answers for this set can be seen here:

One answer is that the depth of the water is measured in fathoms and rope length is measured in feet. ; ) Actually, I'll still curious too.

I looked for a patent but didn't find one, so I don't have any information on how it works.

Maybe the boat doesn't have to stop for it to work (tougher with the rope)?
