Rivet tool

[DalboyParticipant @dalboy]

Seeing the post on rivet gun and not wanting to take that off of what has been posted, I will start this one.

Is there a rivet tool for the none snap type rivets as used by us model engineers and if so what is the best search term to find it as everything I put in the search shows up as pop rivet guns.

I do have a set of snaps for the size rivets that I have but would be nice to see what is available which does not require a lot of hammering

For a non-percussive type, search for ‘rivet squeezer’. Manual or hydraulic.

The area to search is aircraft tooling suppliers. You would find them from the same people who supply Clecos.

An enterprising person might be able to adapt one of the cheap hydraulic cable lug tools if you could live with the very limited throat depth.

An arbor press might be another silent method.

Polly Engineering do them complete and as a casting in 3 different sizes and Atelier do castings

There was also a design in ME to make your own

It would not be hard to substitute a bit of steel flat or plate in place of the castings.

The green bit could be drawn up on the computer and plasma cut from 10/12/15mm plate to save a lot of hand work.

Maybe someone could find a photo and we could trace over it.

It is a bit small, but has a good outline drawing (of the 45mm version) and written dimensions.

Home made rivet snaps, and support, for 3/16″ steel rivets, plus test closures to determine length of rivet before closing:

Setup for closing rivets using a #3 flypress, which is far more effective than an arbor press:

I actually have the heavy ‘throat’ of such a device, which I purchased from from ‘Avro’ at Woodford [my employer] many years ago. It had been made in-house.

It’s currently squirrelled-away and too difficult to photograph … but I could do a roughly-measured sketch if there is any interest.

We have a set of rivet squeezers at the museum with two different throat depth bodies and about 6 different anvils. I made a pair of custom anvils, not as good as the originals, but they did work. They are intended for use with aluminium rivets which have been annealed. Annealing the aluminium makes them much more ductile for a couple of hours, after which time they self harden at room temperature.

That’s the idea, Jason 

… unfortunately the dimensions on your posted image are barely legible, but the proportions look fairly similar to mine.

They can be read on the Atelier link myself and DC31K posted

Or Here

Thanks, Jason

I hadn’t noticed that … I thought you had had traced over a photo of an aircraft one

… Must get more sleep before my brain shrivels any further !

Thank you all at leas I now know what to look for when I do a search. Also thanks for all the other links and information

If there was an effective search engine, you would find two designs, a standard and a long throat version published in the ME/MEW archives.

Oh the onward march of teknowleggy.

I can’t reach to measure it properly, but the one I saved from Avro was cut from a piece of steel plate a little over 2” thick … which makes it pretty hefty compared with the 16mm of that cute little Atelier one.

Obviously intended for bench, or stand, mounting … it was hydraulically powered.

Now we have a computer model of it, maybe someone could do some stress analysis on the frame.

In a way, the design is sub-optimal insofar as the large and medium versions only differ in width (throat depth).

The force on the rivet will be the same but the bending of the frame will differ between sizes. With them both the same size, either the medium one is overbuilt or the larger one is underbuilt.

Unfortunately, I can’t access the archive as I don’t have a subscription. If anyone has a copy, it would be much appreciated as it would be an interesting thing to make always like to make things as it helps by giving my machining practice, and boy don’t I need it (I would add laughing smilies but can’t find  them)

[JasonBModerator @jasonb]

The forum search using “squeezer” as the search term throws up both Rod’s set of three that he made from the castings and also Brian Abbot’s cut from solid version both report that they work. Brian’s has an additional feature that would stress it less. It also gives the issue number that a design was in.
