Hi Zoe,
Oh...okay...
I do not know what a 'thermistor' is...I will have to see if
anyone I know may have one to show me...
But I wonder, on principle, if making new ones from scratch
might not be a worthy curiousity to explore?
My understanding, so far as 'old' parts...is that the
condition of the part, ideally, is happiest when it matches
innocently, that of the Car itself.
But practically speaking, "N.O.S." ( New Old Stock - being
implicitly distingished as being the exact item as the Car
or whatever came with when it left the Factory, and made by
the correct and same supplier of those parts, as at the time
supplied them to the manufacturer of the Car ,) is
considered the highest...
While 'N.O.R.S.' ( New Old replacement Stock - being a
'period' aftermarket replacement as may or may not be found
to be quite 'exactly' the same as N.O.S.) is second...
And... repaired Original-to-the-Car Parts, shall be valued
variously according to the kind of repair, their appearance,
whether they function as well as they should or did, and so
on...
"re-pop" or reproduction Parts, being some now-a-days
effort, usually are considered the bottom of the Barrel,
but, there are exceptions...and considerations there too...
It all varies too with the taste or aestetics of the owner,
the tastes or expedients or fidelities resorted to by the
repair personel, or, as are (later) held by the 'Judges'
as-may-be if in some kind of Judged event, or, the kind of
Judging event it is...
Few things end up in their overview being as 'simple' as one
might have hoped...
Repairs as can not readily be detected should satisfy pretty
much anyone, so long as the function has not been
compromised...
Good luck to him!
Oh! ...when I was 23 ( which would have been in 1976-7), my
Favorite Cars, for urban settings and Highways, were the
same as now...1933, give or take a year...
Or, if for rural settings, many from the mid to latter 'ohs
all through the 'teens and 'twenties...
A five thousand odd lb. 1906 "Thomas" (among various
others,) with it's hefty 5 or 6 hundred odd cid "Tee-Head",
in-line "6", could hold a steady "80" with four-to-one
compression ratio, and take miles to come to a
stop...'Leather contracting Band Brakes' for the rear Wheels
only...and...I would say that takes guts to drive on a
modern freeway...even if it would be fun to do...
I blush just thinking about it...or is it cringe...?
Anyway...

My son is starting a business restoring old car parts for use by other
restorers. He gets lots of old ceramic (porcelain?) parts that are cracked
or otherwise damaged. Many of these are in moderately high temperature
applications (c. 550 F). He wants suggestions on how to repair them. He
would like to fire them back together in my kiln since he is worried about
longevity of adhesives in high temp environments. I don't think this will
work. Any suggestions on how to do this? Books? Products? He spends
hours restoring beat up old parts to factory specs and painting factory
markings back on. The stuff he does is actually rather fascinating.

Hi Zoe,
You caught me eye here...
The only Ceramic parts I am familiar with on old Cars or
their Engines, would be the Porcelain insulator of the
dis-assembleable Spark-Plugs. Or, on the Ford Cars (before
the Mdl."A") the hi-tension insulators of the
spark-coil-box...
What are the Porcelain parts he is working on which need
repair or restoration?
I gather since you reference a metric temperature method,
that these are not American Cars?
Are these 'porcelainized' exhaust Manifolds?
Yours,
Phil

terminal blocks and thermistor insulators. I should say that since this is
a 23 year old kid, the cars he works on that are "old" are from the 60's,
primarily buicks and especially corvairs, although el caminos sneak in
occasionally. Currently he is working on some thermistors from corvair
racing heads that are cracked. NOS thermisters sell for $280, so repairing
ones with cracked and chipped insulators is an option. He also has some
terminal blocks from a 30 or so buick that he is trying to do something
with. it is cracked, and appears to be an industrial porcelain. I gather
in restoration, an original fixed part is best, followed by NOS.
