Geoff Wooff Posted October 18, 2012 Share Posted October 18, 2012 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. Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...

Could try this link http://www.wessexpic.../product65.html If I read it right 11 gauge is 3 mm? Link to comment Share on other sites More sharing options...
Geoff Wooff Posted October 19, 2012 Author Share Posted October 19, 2012 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". Link to comment Share on other sites More sharing options...
wes williams Posted October 19, 2012 Share Posted October 19, 2012 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. Link to comment Share on other sites More sharing options...

Anyone got some to sell ? I'm obviously not the only one who would like a supply of these. Edited October 19, 2012 by Geoff Wooff Link to comment Share on other sites More sharing options...

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.

SteveS Posted October 19, 2012 Share Posted October 19, 2012 The rivets holding on the manufacturer's & number plates on some models are even thinner than those used for the bushing plates. So 2 dimensions of bif rivets are required ideally. Link to comment Share on other sites More sharing options...
shelly0312 Posted October 22, 2012 Share Posted October 22, 2012 http://www.clevedon-...d-rivets-7.aspx ...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 Link to comment Share on other sites More sharing options...

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.microfast...rewThreads.aspx http://www.modelfixi...hine_screws.htm http://www.lancaster...chinescrews2012 If m3 is not too big, these are readily available from Screwfix in the uk in stainless steel. http://www.screwfix....ack-of-50/32952 Just a thought, maybe suppliers to clock repairers may have odd fixings?

Dirge Posted October 23, 2012 Share Posted October 23, 2012 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.

Chris Ghent Posted October 23, 2012 Share Posted October 23, 2012 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...
