Poor Man's Rivet Sorter

They exist for large quantities of rivets, but what if I want to just sort a few?
  [vote for,

I was reading Matt's RV-7 Project blog <link> and wondered if there is an easier way to sort various-sized rivets that sometimes come grouped into a single bag.

My idea is to take a piece of Delrin® or other hard plastic and use a router to cut an angle, equal to the angle of the rivet head, along the length on each side angled towards the center.

At the botton of the vee, an additional slot that is equal to a specific length rivet would be routed. You could have multiple sorters for different size rivets.

You should be able to pour the rivets into the trough and they should settle into the groove and all rivets beyond the depth of the groove would stand "proud" of the trough. Remove these and you should have all equal length rivets.

If you start with the shallowest (smallest) slots and work your way up, you would be able to sort a large quantity easily and cheaply.

       Rivetting. Absolutely rivetting.   

       On the same catalogue page as the glass eyeball sorter.

       You don't say how to remove the long sized rivets. If you have a thin plate that slides in from the sides to partially cover the heads of the rivets, this would hold them into the slot. Then you could just dump out the ones that are too long or didn't enter the slot properly. It could work with only one such plate. If the sorter is somewhat flexible, it could have a slight lip built-in, to grab the rivets.

[Idischler], it's best to keep all the glass eyes organized in the eyeball cabinet. Once they get mixed up, it's over.

       [Amos Kito] I like the addition and it still keeps the spirit of the idea. Thanks.

       Bun. This would work out much better than paying the nephew 5 bucks to sort each bag - cheaper in the long term, there'll be fewer mistakes, and it won't quit in the middle of the job to go play Guitar Hero!

       Could you not simply borrow a rich man's rivet sorter? Mine is called Jabbins, and he's free on Wednesdays.

It's the dang kids playing marbles with them. They lost them in a game of ring taw, and now old granddad Jabbins is using a pair of brass rivets. I painted spots for the pupils, but it ain't the same.

       True. Never keep the glass eyeballs and the real eyeballs in the same pocket.

       I would use a vibratory feeder to get them all in the same orientation, and then run them along a track with holes of different lengths, like a coin sorter uses.

       If you shake eyeballs too much, they go all squishy. How about a current of cooled saline, with progressively larger holes that they can bob up through into holding tanks ?

       I can hardly believe that I've managed for so long without a rivet sorter - it seems so essential that I'm now compelled to buy a giant bag of mixed rivets and set this device into action.

       Maybe there is hope for you after all [xen].

       I'm going to have a sleepless night counting rivets instead of sheep.

       In that case you may wish to invest in the Combined Rivet Sorter And Counter with the additional Ovine Enumeration option.
