Bifurcated Rivets.


Recommended Posts

I'm about to replace the Bushings of a Metal ended Wheatstone but it has those small bifurcated rivets which hold the wooden bushing plate to the metal end. From memory these can be tricky to remove without either damaging the wooden board or the rivets themselves.

 

I recall that the last time I did this job I replaced the bushing with the wooden plate and rivets "in situe" but this time I want to remove the wooden board.

 

Any suggestions ? Like where to buy new rivets of this type or replace them with something better.

 

Geoff.

you are looking for a split rivet

 

Google :APPROVED VENDOR 6LB78 Split Rivet 9/64 Pk100, from Tizaro

 

there are various lengths and I don't know the correct diameter off hand, but this is about 3.5 mm

Am I missing something? As far as I can see, the smallest size on offer here has a head diameter of 5/16" - way too big for the job (and brass-plated to boot!) But if anyone knows of a source of nickel-plated rivets of the right size, I bet I'm not the only one who'd like to know.

Could try this link

http://www.wessexpic.../product65.html

If I read it right 11 gauge is 3 mm?

Hmmm, interesting.... perhaps '14' might be better, if that is '14 Standard Wire Gauge'... I will have to look at what hole size I have, which will mean removing one( perhaps ireplaceable) rivet.

 

As I always think when it comes to old things that are not much utilised today "someone somewhere probably uses these, for something".

How many do you need to get you through this job?

 

Almost 40 years back I wrote off to somewhere trying to get some. The reply was a small bulging envelope, no letter, no invoice, just a small plastic bag of bif rivets. They definitely fitted a metal end Wheatstone Aeola I had. If my memory is correct, they came from here , but they don't seem to do them anymore. But it might be worth contacting them.

Hi Wes,

a dozen would be enough.. it is a big-ish Aeola Maccann.

Anyone got some to sell ? I'm obviously not the only one who would like a supply of these.

I've found this site also http://www.clevedon-...d-rivets-7.aspx

Looks as though they're industrial suppliers though may be worth talking to.If you look at the download page there is a full product brochure with a detailed table of sizes & specs for tubular rivets.

...wow, is that the perfect picture of what you guys are speaking of; it was in my minds eye, but it is always good to have a confirmation. What an interesting use of an interesting bit of a part. Concertinas are certainly confounding in their construction. I always appreciate these give-and-takes from you repair and construct guys! shelly

Yes that is it.... but getting the things in the size one needs Aggggg!! Originally, before and perhaps after the use of these B/F Rivets, a very small wood screw was used.... but getting them will perhaps prove just as difficult these days. I notice that Wim Wakker uses some very small screws to hold metal inserted sections on his wooden ended models.

However, replacing these very hard to find Rivets with tiny wood screws hardly appears to be an option because of things like "hole size variation" ..bigger holes being in the bushing boards due to Rivet useage.. screws won't grip unless holes are filled and re-drilled.. if screws could be obtained etc etc.

 

It can be a whole load of fun Shelly .

Are machine screws with nuts an option? There are several options here, including some withLow profile heads ( micro fastenings)

http://www.lancaster...chinescrews2012 If m3 is not too big, these are readily available from Screwfix in the uk in stainless steel.

Just a thought, maybe suppliers to clock repairers may have odd fixings?

Could you make them Geoff? Drill a hole the size of the rivet shank through a piece of scrap metal and put a slot in one side so you you can grip a piece of the right sized rod in it in a vice. Bifurcate the end (jumior hacksaw and needle file). Turn it over in the gripping device, hacksaw to length and mushroom the head with a small ball pein. You don't need dozens after all.

My first thought was to make them and I envisioned the use of a lathe. Turn the shaft down, bifurcate with a hacksaw, separate with a parting tool ground to the head shape. My second thought was, there's enough to make, if you can buy them do it...
