Looking at the photos of the balanced handwheels gives me another idea.

Could you modify the design so the strap connecting the hub to the rim is thicker opposite the handle?

That is exactly the test that should be used. Is this of benefit to a large number of people or just a few? Even non drivers can benefit from public roads. They can walk or bicycle on secondary roads...

Most things are determined by the forum software, which is used but not created by PM.

Therefore I think the idea of a separate login for personal vs moderator duty is probably the only solution....

EmanuelGoldstein is 100% correct that the only way to do it economically is before bending.

A low buck way that might work is grease hydraulics. You'll need to make two mandrels long enough to...

Tungsten is an even better choice.

I wouldn't worry. Denmark is one of several countries where apparent sea levels are falling instead of rising. It has to do with plate tectonics. Venice on the other hand is in big trouble because...

Until only a few decades ago China had lot's of people but very limited military might (compared to western forces). They had to stop and rethink their strategy after their disastrous attack on...

It's also a problem for Hong Kong, Taiwan, Malaysia, the Philippines and Vietnam. Eventually it may be a problem for Japan and maybe even someday Australia.

China has plans, BIG plans, and they...

And that decline started approximately 50 years ago when Richard Nixon was convinced to adopt Henry Kissinger's principles of Ostpolitik and began to engage with China, convinced that having economic...

I note the Band-Aid on your thumb, You must be a machinist. :D

The buttons look great, well worth the effort.

Have you registered as a foreign agent yet?

I’m only half kidding, as your efforts on behalf of China on the PM forums have been pretty blatant.

You are constantly knocking the U.S. while...

The word "them" in this case referred to U.S. officials. It was in response to Sino-fan-boy's snide remark about the Soviet Union being dead and no longer a threat.

Taping some rubber onto the outside of the flex pipe in certain locations will also help. If you want the ultimate in dampening bore a hole through both sides of a plastic wastebasket and fill it...

Yes, but somebody else told them what a threat China was becoming.

(Hint: The information came from within the Chinese government in the form of a threat.)

Back when I worked for a company that manufactured consumer products in China I was told that one of the obstacles to quality was the Chines practice of moving people from rural areas into cities,...

Trboatworks has exactly stated the case. The argument for "defense only" precludes a navy that can go anywhere in international waters and might even actually be inadequate to defend U.S. coastal...

He's something "ish" but I suspect it isn't Amish.

Back to the subject of the actual cost of power from windmills, there are some situations where they absolutely make economic sense.

One such case is in the state of Hawaii. Normally electricity...

I think what he was alluding to is the issue of adding more generating capacity that is intermittent in nature to our current grid system which is based on a demand model.

In a demand based model...

It's worse than that. The true cost of wind power (and solar) should also include the costs of spinning reserves, which are natural gas powered turbines that pick up the slack. Wind turbines only...

I dispute the notion that "we likely will all/most be driving EVs in the near future". Most of the people I know have no desire to own one and no plans to own one in the foreseeable future unless we...

Not to hijack the thread but one thing I've always wondered about is if there is any simple way to test the UV protection of an auto-darkening helmet.

Although they are supposed to meet the...

Sorry but the site owner has forbidden discussion of hobby type machines here.

Let's for a second pretend climate change ISN'T real, what are the actual costs of "alternative energy" and how would one add them into the equation?

Co2 is NOT a pollutant. If it contributes to...
