Thanks for the book, err - reply ;-) Congrats on the new addition to the

Glad to hear the 'American' is still in the works and thanks for the info
on the alu. bronze, I wondered why it wasn't used more often! I suppose it
would be good for bearing material?
Please do keep us informed

PeteH,
That's a no no. Aluminum bronze should not be used

OK, Arthur's note makes me wonder -- just what IS aluminum bronze good for? Just in
case I might need it and not know some day.

Thanks for the info Ken.
So, how is the American project coming along? I don't recall seeing any
'progress' posts in quite some time?
Kindest Regards,

Hi Group,
Regarding the warpage of cold rolled steels...
I learned this in Machine Tool Tech school years ago, and I'll relate my
crude understanding as best I can: When cold rolled metals are rolled out
into sheets, stresses are created on the surfaces which are greater than the
internal

This is as accurate a description and examples of the problems with CRS
as I have heard lately. Obviously it has it place and uses, otherwise they
wouldn't make the stuff, but one has to know how
I've used 304 s.s. for laser cut frames (1/8) recently and not noticed any
warpage after cutting axle box slots. Laser cut connecting rods (1/8)have
been slightly warped but I attribute that to heat generated during the
cutting process. In any case, the slight warpage was easily straightened,
) or in a toaster oven in the shop.
Just an idea.

I can't recall the temperature but my understanding is that steel must

Dear Jon,
Excuse me but I have to correct you on your concept of

any other metal

We have some 900C+ annealers at work... though I don't think they'd let me
try putting a piece of mild steel in with a wafer. *devious grin*

Oooops um yea 400C is more like it, sorry.

Actually, it probably will. The self-cleaning feature on ovens made in the past 20
years
or so raises the temp to 900F (482C), which should be sufficient.

Anybody uses 4130 steel as used in the aircraft industry? I do and find it

Tim,
4130 steel is for case hardening. In it's soft state it can be used for
anything in a model locomotive where a steel component is needed.

I have always used hot rolled steel for frames. It seems cold rolled
develops stress areas and loses it's shape or warps.

I use what sheet metal shops call black iron (at least here in the
South.) This is hot rolled mild steel plate (or sheet) and it has a dark

Pete,
If you are going to weld the components of the frame together and then
machine the area that was welded you will have to use a low carbon steel
like Cold Rolled steel known as 1020 or 1018 or iron like in bars of iron
you buy in a hardware supply store. They sell angles, round, square

By larger objects I refer to main frame members and the such. Am I correct
to assume that it is not so much a strength issue but more of a
machinability and/or cost of material?
For small engines, like gauge
Well, looks like about half of you like cold-rolled and half like
hot-rolled!
Here is a snipit on hot versus cold rolled carbon steel sheet from Carroll
Smith's book Engineer To Win : I do not want to know about hot rolled
steel sheet. Admittedly it IS more malleable and therefore easier to form,
I, too, have heard the warnings about stress deformations in cold-rolled. But I wonder
if
it makes any difference in this scale. I've seen loco frames made of brass -- much
softer
than steel -- which were quite rigid once they were stayed with three or four cross-
members. I feel like steel
