Does this exist? I want a 3D simulation program where I can experiment with gears (including bevel gears), slots and slides, eccentric cranks, levers, maybe even chain drives and belts and pulleys. Ideally I'd be able to change sizes, numbers/shapes of teeth, location of the drive shaft, etc. to see how those changes affect the motion of the gadget. [more inside]

I have a BS in mechanical engineering and a couple years experience performing FEA simulations for a company in the US military/aerospace industry. I recently found out that there are consulting firms out there charging a lot of money for the same type of services I perform.
If possible, I'd like to get my PE license and begin offering my services on a freelance basis. If I can do that successfully, I'd like to form my own consulting firm.
My main concern is that I won't be able to find clients. How can I find my way into this market? I've heard that a lot of CAD work is being outsourced and I'm not sure if the demand for these services is really there.
I've searched for mechanical engineering listings on freelance sites but I've mostly found low paying odd jobs. My ideal customers would be legitimate companies that need reliable FEA services but are small enough to not have their own mechanical engineer. How can I find these customers? Any suggestions will be greatly appreciated. Thank you!

I'd like to buy a used (or possibly
new) reliable, easy to use mechanical (versus computerized) sewing machine available in Britain or the EU for very basic uses, mostly hemming, repairs, and making simple things like pillow covers, curtains, table clothes, etc., and I'd love some recommendations. I'll probably be looking mostly on eBay UK and Amazon UK. [more inside]

Prepping a car camping trip. I never take pork or chicken when camping in an effort to respect food-handling volatility guidelines. I do, however, ignore those same guidelines with respect to eggs and bacon (bacon is preserved and, well, eggs must be served with bacon at breakfast when camping).
I have been requested to bring 'fresh prawns' to grill. There is no water onsite and there will be no temperature-assured cold storage, but we will have an ice chest with other cold-dependent consumables in it such as the eggs.
The campsite is in the mountains of the Pacific Northwest and averages daily/nightly high-lows of 72/52 at this time of year.
Cursory research appears to establish that prawns are in the same set of volatile meats that pork, chicken and crab belong to. It may be reasonable to source and bring hard-frozen prawns and cook them from semi-thawed.
Departure to campsite expected drive time about five hours; departure to food consumption expected out-of-fridge storage time estimated nine to twelve hours.
I am leaning toward saying no to the request. Hive mind, your analysis please.

I browsed pocket watches on amazon.com and I noticed that nearly all mechanical ones show the skeleton movement (gears) inside. And it is not pleasant on the eyes. Why do manufacturers not hide the inner workings with cover, like the old times? Do they try to say implicitly "Look, we said mechanical and you see it yourself, no battery inside" ? Or is there some other reason for producing these ugly watches?

A few weeks ago I asked this
question. Consider this a follow-up question.
I have a 1993 Honda del Sol 5-speed Si that has a "mystery" problem of sometimes starting and sometimes not starting. It's always a cold-start problem. I put the key in the ignition, switch it to ON until the check engine light goes on, the fuel pump pressurizes, and the main relay clicks, and then crank it. Sometimes it will fire up right away. Other times the engine will turn over but not ignite. Once it is started, it will start up fine for the rest of the day. It only gives me trouble when the engine has gone completely cold and has been left untouched for upwards of four hours.
A new issue has developed since I first posted my question. Even after getting the car started, sometimes just a few minutes later during a sharp acceleration (approaching 4000rpms or more) the engine stalls out. I have to pull the car over and start it up again. It always starts up fine after that and will usually not stall out again. I had this issue looked at by several mechanics, most of whom hadn't the slightest clue what it was or willingness to investigate. The last mechanic I took it to said it was a faulty ignition switch and replaced it . . . but that has done no good whatsoever. Also, just FYI, the spark plugs are relatively new.
Any thoughts are appreciated!

About six weeks I purchased a 5-speed 1993 Honda del Sol Si. Overall, I'm very pleased with the transaction. It's in great shape and runs very nicely.
However, ever since a few days after I bought it, I've had a very frustrating recurring problem.

I'm looking for a book that was out around 1997 (the last time I remember physically seeing it) that detailed lots of different mechanical machines Chris Ware had designed/made, many of them coin-operated. I really should've just coughed up and bought it right then, because I've never laid eyes on it since, and no bookshop staff have been able to identify it. Do you know what book this is, or what it's part of, and if by chance it's still in print? [more inside]

Giant erector set filter: I am looking for fittings used to join square tubular steel in various ways without welding, for purposes similar to a large erector set. This is for self-fabrication of a large solar panel mount. The pipes I am using are square in cross section measuring 4 inch x 4 inch or 3.5 inch x 3.5 inch. I'm looking for straight splice joints, T, L, X, and 45 degree angles. [more inside]

Help me spend my $100 Mechanical Turk credit !?! I have about $100 credit with Amazon's MT system and I haven't used the service for about a year. I just don't need it for anything. If you know what Mechanical Turk is (see here
if not) please tell me how you would blow through $100 just for fun (or good use or charity or save-the-planet, etc.)

I'm trying to choose between bachelor's degrees in mechanical engineering and electrical engineering. Other than jobs where you are actually "engineering" things, what jobs would each one be able to get? Also, I hear that engineering disciplines overlap in some ways. What are the similarities and differences between electrical and mechanical?

The A/C on my car ('92 Honda Prelude) works great from 0-40 mph. Above 40 mph, the ratio of cool to hot air moves decidedly in favor of hot. Any ideas (besides the obvious: take it to the shop).
