Re: Bumper-mounted trailer hitch bracket for Jeep Wrangler TJ
Real Jeeps have a triangular reinforced frame for mounted PTO power
equipment, of course it will hold a class three ball:

*******sigh******** I'm probably pissing into the wind on this one, but
here goes anyway. Why not just do it, cover the situation where
"Someone Else" might be tempted to overload it. This is called
engineering. Plan for the worse.

The rev head culture amazes me too sometimes. Driving to the local
shops in a 2 ton 4wd vehicle fitted out to blast through the Amazon
Jungle defies logic. But as long as they dont do anything to kill me,
they are welcome to it. So, by your logic, refusing to take even
minimal precautions against misuse is OK because "other people" do even
more stupid things. Do you write software this way?

Written by a true, tunnel vision, engineer. A pity that the rest of
the world doesnt, or cant think like this.
Richard, you posted the design on this group. People responded. You
negate any feedback you receive. They are not personal attacks - at
least, not until you started responding in a silly manner.
One of the beginnings of maturity is recognising how little you know as
an individual. Intelligence is then finding the information you need to
overcome this. It is not just "Jeep trailer hitches" - its for the rest
of your life, and your life to date, as well. Think about this -
please - your life might start to get better and less confrontational.

I am an engineer.
I define engineering as the economical application of scientific
knowledge to a physical application.
To "plan for the worse" is not engineering, if the worst is not worth
planning for. It is spending too much on the biggest and baddest in the
catalog, which is the anti-engineering mentality of "I built it as
strong as possible, so I didn't have to think about it, nothing more
could have been done". You don't build a wooden crate when a cardboard
box will do, even though it won't stand up to a gorilla jumping on it.
Look, the item tows my boat, economically, and with some material
analysis, albeit casual. It does not fit the worst case, nor is it
intended to.

Ya gotta love Usenet. Posters simulating critical thought with

A (smaller) backing plate is only a glorified washer, good only against
shearing through the attachment point. The rest of the bumper will have
failed before that happens, so it adds nothing.
A larger backing plate would be tantamount to replacing the bumper with a
stronger cross-member, and at that point you might as well put on a frame-
mounted hitch instead of using the bumper.
