Default Bending an eyebolt. . .

. . .is officially a Bad Idea, just like bending any bolt, but if
someone [cough] wanted to have the eyes of a couple eyebolts knocked
over about 45 degrees, is heat a good idea? How much attention should be
paid to the radius of the curve?

These would be small eyebolts, the i.d. of the eye is about 3/8 in. Not
much force will be applied in service; it's to attach a small instrument
panel to a plastic panel in a motorcycle.

Suggestions, jeering etc. are welcome.

The hardware store eyebolts (eye is formed from rod and not welded) are
usually hot rolled steel that bends easily without heat. Just stick in
the vice and use an adjustable wrench. Of course, they have no strength
to begin with so nothing lost.

I might add that my local home store had some inexpensive "1/4 inch"
(rod diameter) eyebolts. When I got them home and tried to add some
additional mounting nuts, it worked out they were 6mm metric. They got
them back as "mismarked and misleading"

Just get "Oriental" eye-bolts.

V-block below, eye bolt, bar stock sized for the radius you want, and a
hydraulic press. Go slow & easy and stay out of the trajectory for
when/if it snaps. You'll want to use mild bolts, this isn't a time for
something brittle.

If they're ordinary mild steel eyebolts, just bend 'em cold. I'd grab
the eye in the vise, slip a piece of pipe over the straight part and
pull until the desired bend was achieved. A brass hammer, or a steel
hammer with a block or drift of brass, aluminum or hardwood would also
do it. Heat would burn off the plating and they'd then rust
quickly unless replated or painted.

The steel bolt will still be considerably stronger than the plastic
panel to which it will be attached.

Sounds to me like what he really wants are ring-bolts, or tie-down
bolts.

Saw the eye open. It is less stressful on the bolt and you might get away
with it if you are careful.
Bending might weaken the entire eye.

I think you misinterpret what Bennett meant; he isn't opening the
eye, but instead is tilting its circle at 45 degrees, then bolting
through the eye to a panel to support it at desired angle.
