Re: MEK sources

In the sixties I lived in Milan and was flying model airplane. There was a shop in the center of town that sold, to a 15 years old, the ingredients to make the fuel: Castor Oil, Methanol, Nitromethane, Amil Nitrate, Ethyl Ether all of which can kill you.

Re: MEK sources

In what application would you prefer to use MEK instead of Acetone? I just finished a can of MEK and replaced with Acetone, for my purposes (thinning and de-greasing) they seem to work the same without the MEK toxicity. I think the banning has to do with its status as "Table II precursor under the U...

Re: Tesla cars

The charger is in the car.
I did not know that. So the connection is AC and the charging time depends on the cable size and the AC receptacle on the wall capability?

Basically the size of the extension cord set the charge time. Of course you must have the proper service.

Re: Tesla cars

For the rare long trip there are options, like rental.
My wife wanted a 7 passenger SUV "for when the children come" ... once a year. We have a second car so is no problem going anywhere with the grand-kids.

Wavy Parallels. What are they good for?

I have a set and very rarely feel the need to use them.
The only application I found the useful is to drill a hole so close to the jaw that it will hit a regular parallel.
By positioning/guessing the location of the parallel so that the hole lands in the right spot of the wave.

Are they compressible?

Re: Rant about Home Depot

I have great success finding what I seek at Home Despot. Sure! If you only seek what they have. 3/4 of their inventory classify as hardware, by that standard they seems to be a hardware store. But they are not. They are an opportunity store, if belt driven shaking booty come fashionable again like ...

Re: Rant about Home Depot

Taking Harold gold data the ratio quoted is 59.15 In Gold parity terms the $3/gal fuel of today is $0.05 adjusted for inflation. Of course all is relative, price is just a number. The real value is the time of paid labor one has to expend to obtain the good. That depends on how fast the money rolls ...

Re: Choosing an end mill for the job

increasing the cutter diameter increases both the thickness and length of the chip so chip volume increases faster than diameter. This means that material removal rate increases with diameter at constant surface speed. Top I do not see the geometry justification of that. True the chip is longer bec...

Re: What is This Thing?

The cap has a bail latch. It may be easy to open and seeing the inside may give you a clue of what it does. Not necessarily what is the purpose.

Re: Layout dye

Has anyone else ever had a problem with spray cans leaking or exploding? I was painting from a can of red enamel. The nozzle plugged, but for an insane reason I thought it fizzled out so I poked a small hole on the top. Gas gushed out, but not fast enough for my taste, so I pounded a bigger hole. M...
