Fitting rivets
« on: April 18, 2018, 08:51:48 AM »

Is there any particular special technique for fitting rivets when replacing a reed tongue? I assume you just hammer them. But can anyone advise on, for instance, if reed makers use a press, or a punch with a concave end, or a particular hammer... would a small ball pein be the correct tool?
FYI I’m replacing some bandoneon reeds.

It is a facebook based joke re my fixation with Victorian industrial/architectural installations and more specifically their rivets.

Unfortunately I know little or nothing about reed rivets.

Yes you need a rivet set which has a hole in the end of the same diameter as the shank of the rivet.  Place the rivet into the hole in the plate, place the tongue over the hole, then with the head of the rivet on a suitable anvil give a sharp tap on the rivet set to ensure the rivet, plate and tongue are snugly fitted together.   Then with a ball pein hammer work around the edge of the rivet gradually deforming it to spread out and hold everything together.  Some rivet sets also have a hemispherical hollow to form a rounded shape on the clenched rivet, but traditionally these are not used on reed rivets.  Then you need to align the reed tongue with the vent.   There are several videos showing this, like this one on facebook https://www.facebook.com/jurgens.ciccarelli/videos/926114247527471/?q=jurgens%20ciccarelli

Thanks Theo...I hoped you'd be along to explain it. Unfortunately I can’t see anything at that link.

Ah yes, thanks. I was just watching that one. He already has the rivet set up (probably as you describe above) and then hammers it  (as I was expecting).
Anybody know what rivet setter/punch  is in Italian?

GIYF

https://translate.google.co.uk/?hl=en#en/it/rivet%20setter

I don’t think it translates very well in this case.
Here is a reed rivet as sold by Carini ... they probably have the setter tools as well. I guess I’ll just ask them.
http://www.carinidena.it/MS5ECOMMERCE60/jsp/eco_cc_home_bs_portlet.jsp?p=dettarti&codarti=33032000600

...bulloncini ferro... translates to 'iron bolts'

I can probably make a setter tool.

A better tool than Google translate in this case would be Linguee, which shows actual translations in context. "Rivet setter" gave nothing of interest, so I tried "rivet tool" which produced rivettatrice manuale.

https://www.linguee.it/italiano-inglese/search?source=auto&query=rivet+tool

Doing a reverse search for rivettatrice on the same page suggests that it can mean a person (riveter) or a machine also, so the addition of manuale should, er,  nail it.

Edited to add: check https://dictionary.reverso.net/italian-english/rivettatrice

It will probably be a cold bluing solution for steel. It creates a thin, (relatively) impermeable oxide layer on the steel preventing further oxidation beneath. Used mainly by gunsmiths and gun owners. Also in a heated form by clock makers to make that intense deep blue colour on clock hands.

Various suppliers. Here's one:

I think thats unlikely, I’ve never seen a reed from any maker that was blued on the top surface.  More likely it’s a corrosion inhibitor of some sort.  Most reed makers apply some kind of of passivating treatment to the reeds.

Ah yes - you're right. I thought it was going on the underneath surface. Must watch more attentively!  :|bl
