The biggest problem with with 'pop' rivets is whether they are open or
closed. An open rivet is relatively easy to drill out.....it's just a
matter of knocking the 'mandrel' out (the piece that expands the
rivet) &
then drilling the head off, then the shank can be 'knocked through'
with a
centre punch!

A 'closed' rivet is a different kettle of fish, normally the mandrel
cannot be knocked back...it's a matter of drilling the 'head' off & then
knocking back with a punch and expanding the origional hole.


When is a pop rivet not a pop rivet?

When it's a monobolt http://www.erivet.co.uk/monobolt.htm

Looks like a Cherry lock to me :-)

Wish there was a decent drill sharpener on the market. I have two and
they're both near useless on anything other than large drills. Which even
I can do as well on a grinder by eye.

You don't need a drill sharpener. It is a bit late in the night to
describe the method. But if I have not gat back to you within 24 hours.
Feel free to poke the e mail address.

The last thing is that standard HSS twist drills dont work that good
on ali, try a gold coloured coated bit instead..

Sorry, but that is just plain nonsense.


well I'll take your word for it. I thought ali tended to stick to hss
at higher speeds.

Only supersoft crappy alli.

If drilled or machined dry, ally tends to stick to any cutting tool.
Applying a lttle parrafin occasionally, is usually all that's needed to stop
it happening.

I don't think mono's would be allowed on aeroplanes ;-)

I used them (in a past life) when I worked for a trailer manufacturer.

It will take quite large ones if you want. Use the upload file page for
the photos:

http://wiki.diyfaq.org.uk/index.php?...Special:Upload

Then you can drop them into your article with a simple reference in the
text like:

[[Image:RCDSocket.jpg|Socket with built in RCD]]

The bit after the | is the name you want to appear in the alt image for
the photo.

Just select any other article and click "edit" for an example of how to
markup your text for special features etc (only don't same it unless you
want to change it).

OK I'll give it a go later on, when I have some time to put it together.
