Hi Meir,

Expando is a plastic mesh that slips over cable bundles and can be pulled
tight to hold the wires in a bundle. It is sort of like some WW II stuff
used by the RCAF, but that was cotton. (It is a small version of the stuff
used on some wine bottles and candles in jars). For example:

http://cableorganizer.com/Bentley-Harris/

It has been used by most of the big aerospace companies for 30 years +/-
to make custom cables for GSE. It works very nicely, IMO. It's made by
Bentley-Harris.

It can often be either salvaged from useless cables or bought on eBay. New
it's expensve.

Best,
-John

==================





> As John said, get the manual. I got a copy of the manual from Robert,
and it's indispensible in wiring the controls and maintaining the radio.
>
> My ARB to control box cable was homemade by the previous owner and it's
ugly because the individual wires are all the same color and gauge (#14)
but the length is only 2 feet - and the whole "bowl of spaghetti" is not
encased in a sleeve. I'll have to completely rewire it to look decent
and use the correct gauges.  If I recall, the manual calls out the wire
gauges and has an assembly drawing for the control cables - I'll look at
the book when I get home from work. Bear in mind that the control box
switches the primary 24 V feed to the
> dynamotor/filaments so the 24 V line should be large enough to carry the
current without any significant voltage drop for the proposed cable
length. The other wires are just control wires, but the
> bandswitch lines also carry some current at 24 V to the bandswitch
motor. I don't think it's more than an amp or so.

> John, I've been looking for some tubing which has the looks of WW2
vintage rubber cable jackets. I was thinking along the lines of
> thin-walled rubber tubing, but my search is unsuccessful.
> I don't know what the Expando sleeve is, I'll look it up.

>> Have you looked at the manual? Robert Downs likely has copies.

>> I'm pretty sure the cables are pin-to-pin w/o cross-connects, but
that's not certain.
>>
>> If you want period correct wires, that is not easy. I generally use 19
strand white Teflon hook-up wire, roughly #16 to #20, inside a jacket
of black or white Expando tubing.

>> Ready made original cables are likely still in the planes.
