copper clad paxolin

I've seen a lot of references to this stuff - where can you buy it from and
how much does it cost?
Cheers

If you're thinking of making track, then don't look at buying sheets
of the material. The most common modern material used in copper
clad circuit board is a type of fibre glass which is sudden death to
most types of cutting tool. So cutting out sleepers can be a hard job
in the home workshop. You can get SRBP board as well but it tends
to be a bit thick for sleepering in the smaller scales and ain't that
easy to cut either.
There are several suppliers of ready cut sleepers and here's a sample
of one supplying 4mm scale products.

You can also get them in 2mm, 3mm and 7mm scales if you look around.
If you are looking for sheet there are many suppliers such as

http://www.rswww.co.uk
http://www.electrovalue.co.uk
and search for PCB or Printed Circuit Board. For model railway track
work it is advisable to get single sided material. Double sided
material can cause some interesting short circuits when you use metal
pins through the sleepers.

No I don't have the patience for all that ... if I do move to "hand built"
track I've no doubt that I'll go for C&L.
What it is I'd been having one of my periodical slack jawed mooches around
the "Dyserth Road" website and I saw the article for fitting additional
pick-ups on the Backman 08. Well to cut a long story short I've got a
feeling that the technique can be adapted to a wide variety of stock - cheap
and chearful as it is. A lot of my stock is old, second hand and to be frank
a little past its best, certainly additional pick-ups would help a lot of
the stuff and this method has some distinct advantages over teh techniques
I've been using so far.
I should really join a club, whenever I start on something I tend to spend
half my time trying to reinvent the wheel.

<blush>Doh! ... is that all it is, PCB board?</blush>

If you're just looking for smallish bits on which to mount pickups,
look at getting some 7mm scale point timbering strips which are 7mm
wide and about a foot long. They are probably around the width you
are wanting and it's quite easy to hack them to the lengths you want.
(A big pair of side cutters does the job very well :-) ) That might
be easier than having to buy a biggish sheet of the stuff from
electronic suppliers and cutting small bits from it.

Depends on the source - 2mm Scale Association sleepers are 0.76mm thick,
which is a scale 4.5inches.
Top tip from the man* I know who makes lots of different SRB based sleepers
for various scales and retailers, not just the 2mm stuff:
Warm the stuff boards a bit before trying to cut it.
(*) Amazing home built workshop which can reduce the thickness of the PCB to
suit certain applications, accurate to under 1 thou ; a fine gapping saw
which only cuts the copper clad, not the underlying board ; a chopping
machine to cut the sleepers to size in an instant ; cutters to mill
"concrete profile" sleepers ; etc.
And a numerical counter which suggests that there are enough 2mm finescale
sleepers for 15km of track somewhere (which is 1400 scale miles !!!).
