After much Googling the only supplier I can find of a 2mm reamer is MsMaster
in the US......and would not send to UK due to 'export restrictions' .......
any other suggestions please.

......also I am trying to find mech. properties for silversteel and piano
wire.

Any help very much appreciated.

Cheers
Nick

Have a look at Drill Service in Horley for your reamer:
http://www.drill-service.co.uk/

Silver steel is a 1% carbon steel easily machined in it's annealed
condition and easily hardened in the workshop.

If you need to know specifics such as tensile strengths and yield
points, then why not contact Stubs direct for information

Have you tried Tracy Tools (www.tracytools.com). They have a very
good range.

Silver steel properties depend on how you treat it (especially heat
treat it). Its a high carbon steel with some chromium, and the
chromium may help its hardenability (no doubt someone will shoot me
down in flames if I am wrong). What properties are you after,
hardness, toughness, tensile strength ?

Piano wire is very high tensile stuff, high carbon steel. I think that
is has the benefit of heat treatment and being drawn through a die to
impart some cold work and get it dimensionally perfect. But like any
carbon steel you can make it change by heat treatment. AFIK its a
plain carbon steel, i.e. negligible chromium or other exotics. I think
in old fashioned units we are talking 100 to 120 tons per square inch
or more (luv them units!).

Thats the wonderful thing about steel, you can soften it to machine
it, and then harden it by heat treatment. And all metals can be
hardened by cold work too (hammering, drawing, rolling, shot peening,
etc ). Composition is just the start, there are lots of different
physical properties, and some - like ultimate hardness - might mean a
tool that shatters if given a shock.

Hi all and many thanks for all the replies.

Perhaps I should have said what I am trying to achieve.

Here's an image of the 'problem'

http://z11.zupload.com/download.php?...filepath=68692

I have made a swing axle for landing gear on a model a/c. I have bent 2mm
(14g) piano wire (?) into a Z shape. I am not sure if it is piano wire or
not, but as it is, it has taken some highish loads without yielding.

I need to bend a radius on the Z as tight as possible without
cracking.....oh yes, and I need the bend angle to be 85 degrees with minimal
deformation near the bends!

Should I use 2mm silver steel or 14g piano wire?...... I have sourced a 2mm
reamer...at last.....and doubt I could get a 14g reamer(?).

Cheers

Nick

Sorry, my mistake, I expected an image, rather than to have to
download a file.

Piano wire. Or spring steel wire. Or possibly something like en24, if
you can get it in that size.

But not silver steel, which is mostly used to make hard cutting tools,
and isn't at all tough, even when tempered.


And yes, you can probably get 14g reamers. One problem might be, there
are several different 14g 's ...

Hello Peter,
I do a fair bit of r/c aero stuff as well so we have some common
ground. Silver steel will almost certainly be too hard to bend as you
require and although I'm not completely clear how the component works,
silver steel will not be very springy. I'd always use piano wire for
tis sort of part.

That said it is getting a bit difficult to get proper piano wire; you
can forget the ground finish junk that many model shops a flogging at
present, I don't know what grade of banana it is but it's crap. As I
expect you know 'real' piano wire has a bright finish from being drawn
The most reliable source is the American imported stuff although it's
in inch (not SWG) sizes and is a somewhat dull finish.

For this sort of job, you'd probably be OK just drilling the hole
rather than going to the trouble of reaming, but guilding the lilly is
certainly nicer.

Hi, just a thought, but would new guitar strings work in place of piano wire
in this situation? Single wire, not the wound type strings?
