Hello Susan, You can cut a 1/2" hole in a piece of metal (iron,
steel, aluminum or whatever) and a couple of slightly larger hoes up
to7/16". Buy some 3/4" copper tubing at the hardware store, anneal
it and draw it thru the holes. Easy.

Have fun. Tom Arnold

An idea… make your own… one can purchase Square stock at
hardware and farm supply stores. anneal 1/2" copper tube and one
should be able to work it over the square stock… just an idea.
These other links should give you more than enough info.

Hi Susan,

I am looking for 1/2" square copper tubing. Does anyone have a
source for this

If you can’t find it ready made, you may have to make it yourself.

You didn’t say how long a piece you needed or if the 1/2" was an
inside or outside dimension.

If the 1/2" is an inside dimension, the total length of the id is
2". If you make your own, you could use a round tube & using a bezel
punch or a 1/2" piece of key stock that has a small taper filed on
all 4 sides, stretch a round tube to a square shape. To find the
round size to start with, divide 2" by pi (3.14). 2 divided by pi =
.6366". That’s just a little larger than 5/8". However, that’s not a
popular size. You may have to go with 1/2" or 3/4" & adjust
accordingly.

The other option is to start with a piece of copper sheet & fold it
into the square shape you need

This is 1/2 the fun of metal work, figuring out how to do/make
something.

I am looking for round copper tubing, not Ace Hardware. Used for
cutting wax circles to set a stone.

Thanks,

Hi,

Thanks for your great suggestions! I put a group email out to a bunch
of metal suppliers from the list that one of you sent me. I am making
3 light fixtures and I need (3) 3.5’ long pieces. Because of the
lengths, it would be hard to pound it out evenly. That is definitely
an option though.

I 'll keep you posted-
Susan

You might have to plate some brass will be a bit stiffer and much
easier to find.

I have found it but only if I want to buy 50 ft. I am thinking of
switching to Stainless Steel because that is very easy to find and I
was going to do cold connections anyway. I’ll post pictures when I
am done.

Thanks for your help!
Susan
