Does anyone know a good source for hi-temp wire ? I am rewiring a LM
and looking for the correct wire. I would rather not have to buy 500ft
of each color and size I need.

If you can't find anything, try a local high performance/automotive
racing/boat shop. They sometimes stock quality wire made for high
temps that they sell either in small rolls or from bulk. A local shop
that builds race cars may have a scrap bin they would sell from cheap.

UL1015 wire will probably match original.

Sources:

Waytekwire.com (I have used them - they do a good job)

Lowes - big box home improvement store. They stock small spools of
1015 in 18AWG, but color selection may be limited to red, black, green.

original is UL3135 and another number which escapes me at the mo', but
which is equally difficult to obtain. the one online source that

Like the great industrial supply house, McMaster-Carr. For 16 awg, two
10' lengths would cost $22.30 plus postage. Powerwerx's minimum length
is 25', two for $33.50 plus postage, a better deal if they're reliable.
And then there's the eBay listing I found: five 20' lengths, $26 total.

"Teflon" covers a lot of territory. Some teflon insulated wiring is UL
rated for 250C. Are you basing your assertion on having bought some from
the same vendor and examined the markings or have you inquired of the
vendor or do you have a TV Crime Show Magic Image Sharpening Tool that lets
you read markings that are smaller than a single pixel from the photo on
ebay or what?

felix inquired of the vendor. the blue is UL1213, which is 105C and
only 150v, but the guy is claiming it's 200C because all the other
wire is "made from the same materials" but Mil-Spec 200C and not UL.

I would try your local auto parts store. Much of that wire is expected
to withstand underhood temperatures, which can be comparable to or
even higher than those experienced inside an espresso machine,
especially during Summer. Look at the ratings, of course, but in my
experience good deals on small spools can be had. Only trouble for me
has been that for whatever reason I can't seem to find white wire, so
I revert to using red for hot and black for neutral. Confusing at
first, but you get used to it.

Good luck!

Thinking about it further, you could of course use black for hot and
yellow for neutral, which is how I wired my popper, and which makes
more sense if you have a familiarity with modern AC wiring (in the
US).

i'm pretty sure the bulk of it (except for element wiring) is 18
gauge, but i usually use 16 ga. the element wiring is 10 ga, i think.

Mine is very stiff. Some of it is 14 awg tightly twisted into pairs,
and the rest is 12 awg with thicker insulation than usual. Both use
PTFE. I think Tefzel only goes to 150C, but what about the rest of the
fluoropolymer family? Strand gauge is also a factor. To compensate for
the extra insulation, my 12 awg is made from finer strands. The cost of
silver plating is an issue, but sometimes it's fun to scour the 'net
for sources of surplus goods. (For a long time, I've been intrigued by
the odd lots sold by Surplus Sales of Nebraska.)

As for stripping ... silicone isn't bad, but Teflon slips off as fast
as a shmoo jumps into a skillet :-)

My point is that automotive hookup wire and temporarily (?) scarce
UL1335 aren't the only alternatives.

I believe 1015 is only rated to 105C, whereas 3135 is 200C. 105C might
be adequate, but why skimp on a LM?

3135 wears a silicone jacket, You can get 200C/600V wire in less
flexible jackets that would probably be adequate and easier to strip,
e.g. McMaster-Carr 7304K14, but silver-plated strands cost more ...

I think I may have wired something exclusively with white-jacketed
cable, coloring different parts of the circuit with permanent markers.
I hope I don't do that again :-)

silicone is easy to strip.. it's that darned fiberglass or
silicone/fiberglass that's so tedious.

the stock wire is Silicones Inc UL3135, 200C 600v.

i've used teflon jacketed wire for some applications, but the lack of
flexibility can be a drawback on some of the hookups.

that stuff is a pita to work with.... which is why, i guess, marzocco
switched to silicone (all my older machines use fiberglass wire).

i'd go teflon before going glass.

With the caveat that I know nothing about how wire is routed inside
your machine, I have to say that I wonder why you and Barry both have
wires that cannot be reused, i.e. if the OEM wire is truly adequate.
Manufacturers balance cost, quality, and assembly convenience when
selecting materials/parts. Rebuilding only one machine, you might be
willing to spend more to get better quality or more convenience, or
endure a bit of inconvenience to produce a more durable result.

I have an integrated amplifier that I built from a kit that specified
that the input signal wires should run across half the back of the
case, past the output terminals, along the right side to the front,
past the headphone jack and the LED indicator, to the potentiometer.
The route along the left side is shorter, but it passes the power cord,
power transformer, etc. I created a short route below the circuit
board, by attaching conduits (plastic coffee stirrers!) to the base.

On the other hand, you bought one of the first Bumper knock boxes
(right?), so maybe you could ask Paul if he uses something like UL3135
when he replaces LM wire and ...

it depends. on my 4-group, i reused the complete glass braided wire
harness, but i had to go through and replace or put heat shrink tube
on every connector. the insulator on the connectors seems to be very
vulnerable to the prolonged heat exposure, as are the terminal blocks.
in other machines, the wires have been overly dirty, damaged, missing,
or otherwise in need of replacement. keep in mind i'm rebuilding some
machines that were moments away from a dumpster, after years of hard
use/abuse/neglect. also, if i modify the wiring for PID or other
systems, it's nice to match up the new wires with the original.

That sounds like the norm for ex-restaurant machines ... I have some
sympathy for the designer(s) in these situations, but also know there
are situations where the designer is supposed to anticipate abuse.

If you decide to use Teflon-insulated wire for your current LM project,
you should consider buying it via eBay. There's a 16 awg listing that
looks appropriate:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=260013238866

I'll mail you more information.

Yes that stuff looks good. I do indeed use 18AWG UL3135 silicone wire
for the control and then silicone with fiber glass insulation for the
heating elements.

I think the main reason a lot of the old machines need to be rewired is
not really one of safety but on aesthetics - although safety is another
big cocern. They almost all have used fiber insulation and many
machines I have only 1 colour of wire. After a while it all looks
pretty grotty.

The other point to bear in mind is the type of quick crimp connectors
that have been used. If it is the 2 piece type VERY commonly used in
Italy where the sleeved cover slides on over the crimped brass part, it
has a tendency to become brittle after a few years. If you then try
and pull that from the switch it is attched to more often than not it
will shatter. Therefore you must then cut the brass part away and strip
the wire - in the process you are removing as much as 3-4cm of wire
which is enough to leave you short, hence a little new wire is needed.

I mentioned to Greg and Barry that I could send some (once I find it
after we unpack boxes at our new office) but it is really heavy.

one thing i've found is some of the glass braid wires will lose their
coloration, with formerly red or blue wires becoming white (if only
for a portion of their run). it can be very confusing when tracing
wires....

finding teflon is no problem; there are several reliable sources.
