Could feed McMaster Carr part numbers on alternate materials that I use to replace the
asbestos pads, but that won't help. Instead perhaps look towards electronics suppliers or Grainger amongst other general industrial suppliers in Canada. Even electrical suppliers.
Most new lamp sockets come with a 1/16" thick silicone pad under them. The same type of silicone that would be used on a
circuit board. Might be an idea there in just putting blank
circuit board material under your lamp
socket. Another option is the rock Mica - you can buy it in sheets of the same
thickness. Further is what's called in the electrical industry "fish paper" - though I'm not sure about it's maximum operating temperature. Most of what I use is
ceramic fiber
heat shield material in sheets or rolls. The
ceramic fibers are bonded with stuff like plaster and other things and can be flexible like an
asbestos tape or solid in sheet kind of like what you would use for
ceramic tile wall backer board - only thinner. All sorts of materials can be used (gave away my home edition of McMaster and yet to get my new copy in getting another one home yet but,) if something non-conductive say 1/16" thick is rated for at least 200C or 450F - it should work fine to
block any short as a pad under the lamp
socket.
Side note, when using many of the above
asbestos looking materials, I take a pen and write on them "not
asbestos." This so the next person working on the
fixture knows not to worry about seeing the
asbestos look like pad in use.
Good to hear I misunderstood your intent. No still on the electrical tape, believe it's common maximum operating temperature is like 75C - so it like does what once inside a lighting
fixture? Remember the time I tried using Fiber tape inside a light.... somked up a storm in smolder fire. Never old in age, we often just take longer to collect up our thoughts sufficient that others younger might understand sufficiently. Remember like rule 8 of the tech bible: "If you think the TD is wrong, you must have mis-understood him." Or something like that. "Brevity is the soul of wit" - thus we are both witless, or we intend to communicate complete thoughts and if mis-understood can than clarify. This as opposed to how hard will it have been to make your post brief and get a good response to it? Did good and now are refining what is needed.
On the wiring harnesses pre-cut and store bought... how much does a 250' or a 500' spool of just plain white SF-2, 16ga
wire cost
thru your electrical or wiring supplier? A can of black and a can of green high temp. spray paint to without having to make it entirely the color - just sufficient to be
clear what color the
wire is and you now have lots of high temp.
wire on demand.
Production Advantage don't ship... lots of on-line theatrical suppliers like TMB, Creative
Stage Lighting, TechniLux, heck, even
RoseBrand, Bulbtronics
etc. and specifically
etc. probably have shipping issues figured out across boarders. Kind of surprised that there is problems in shipping
thru Canada
thru this supplier, but probably just a question of finding one able to do so. This if you cannot get the SF-2
wire thru your local electrial supplier, thatrical supplier or wiring supplier by spool length. Common product and should be easy enough to get with some
leg work in asking. Probably the same suppliers you can get say Scotch #69 Fiberglass electrical tape, from or the high temperature ring terminals from, will also be able to solve most of your other problems.
Don't forget to
ground the fixtures if doing all this work.
Ground wire to the plate the lamp
socket is mounted on and run all
thru the same
cord gripped hole in leaving the
fixture. Fiberglass over
wire sleeving for the conductors as with the above common types of sources is often also available
thru heat shrink suppliers. More or less just a
bit of
leg work and I'm sure everything you could possibly need is available
thru local suppliers. Might try also contacting say 3M for who they recommend to supply the tape, Carol or General
Wire for who they recommend to supply the heat
wire, and amongst many sources, say Pandiut for the ring terminals in loal suppliers at very least. Often on a website, just type in your zip code for a supplier or many. Reverce
track perhaps what you need as for supplier.
Old school P-28s lamp sockets - even if completely re-surfaced by me with a few hundred in experience in doing so might be really valuable in that even
Altman doesn't sell that style any longer. Nobody makes that lamp
socket any longer. On the other
hand, a market for "used lamp
socket" in general even if quality resurfaced wouldn't have a big market. This beyond the "as" is market in there is a lot of the sockets that are beyond fixing. Old school P-28s sockets.. big problem in getting - think I might if I put some parts together field like one or two even. On the other
hand the G-22
socket from the same period, lots of them and even know of a lamp that will work with them if you
jack up the lamp
socket. Also useless info. Save them old parts though even broken parts - good idea. Sometimes you will run across something electrically too pitted that can be installed into a
socket with a bad
porcelain with some work. (Granted this old school lamp
socket saving is all non-UL listed work talked about.)
