Greetings and salutations

After a dozen years or so, my desk chair has become hazardous. I
didn't know you could crack an eighth inch steel plate, just by
sitting on it. But - I managed, somehow. This is the plate which
mounts the connector from the stand up to the chair bottom. Mostly it
got the left-right stresses as I shift around reach for stuff, but I
knew there was a problem when I leaned forward, and it "leaned" with
me.

So, JB Weld. Advertised as being "able to fix anything but a
broken heart", how it is for handling the sort of stresses of a
twisting plate?

And how does it handle stress fractures and failure?

It is either JB weld or I find someone with a welding kit. Or go hit
the yard sales, etc.

boys could lose a finger or two playing with."

You have 2 choices.

1. Replace the chair.

2. Find someone to weld a support plate under the old one..or weld
beefed up "splints" on the cracks. Know anyone who can weld it for
you?

A couple, but I have half the one guy's kit in my shed (the rest
is "in storage").
