[TheForge] making d-rings

[Dan Brewer]

I would use what ever you are comfortable in modeling in.  Wood is very
flexible but will not provide some of the detail that you might want.  So
plastic, or nylon.  You can get these inexpensive cutting boards that are
nylon and they work with wood tools.

Subject: [TheForge] making d-rings

hello;

i have the occassional need for a pair of d-rings.
my occassional need may become more than occassional
if i were able to make my own d-rings. d-rings, are
simple items. as the whether the d-ring is welded or
not would depend on its intended use. the small size
d-rings could be formed cold.

a while ago i watched an old movie about forging chain.
the movie showed a length of hot steel/iron being placed
in a hydraulic bender. formed the chain link in a short
time and one heat. a properly geared handcrank model could
easily make d-rings. that is the key though a 'properly
geared' handcrank model.

whether it is making a link for a chain or a d-ring,
basically it is just link bending pipe.

when prototyping a device or even a project, what do
you use? wood, acrylic sheet, plasticine clay?
