The Output Speed is generally the main difference. To increase the torque (strength)of the drill, the motor is geared down. The motor in the high speed drill and the high-torque drill may be turning at the same speed but the chucks or bit-holders will be very different.\nMost drills come with two speeds. If the speed is controlled by a gear assembly, then the torque is much higher at the lower speed.

Maybe the following picture will give you an idea:\nhttp://pg.photos.yahoo.com/ph/dpeter508/detail?.dir=/c51a&.dnm=b97fre2.jpg&.src=ph\n\nThis is a binary pattern painted on the shaft, with three sensors (red dots in the pic).  The outermost sensor will detect black and white squares, and can determine rotational speed based on the rate that the black and white squares go by.  As the shaft rotates, the sensors will detect the 3-bit pattern painted on the shaft at any point.  If the shaft is turning in one direction, the pattern will appear to "count up" or down depending on direction.

If you need this information to buy a compressor then other factors need to be taken into consideration over just the PSI.\n  \nDifferent power tools require different pressures, and each power tool has a max PSI that is available to it.  For example most cut-off wheels are not recommened above 90 or 100 psi as they would spin too fast and can cause the cutting wheel to explode when it comes in contact with a material. \n\nThe next thing to consider is the time the device will be used.  For example you would probably not want to use a 1 gal tank to frame a house, as you will wait forever for the pressures to constantly be built back up.  Jitterbug sanders require more volume and will use up a 1 gallon tank in a matter of seconds.\n\nSo heres the best thing.  Get a medium sized compressor maybe 20 gallons, get it with a max PSI of maybe 140, and an adjustable pressure output, and you should be pretty good at taking care of just about whatever you need.  You may have some wait time for pressures to be built up if you are constantly using the tools.  But that also depends a lot on the compressor.\n\nHope this helped some

Well there are alot of variables to your question.... water temperature, clarity, depth, stream or pond/lake..... but here are my top three....\n\nGrape soft plastic worm... usually a curl tail... and rigging depends on those above variables.\n\nBuzz baits and spinner baits.... with a slow retrieve.... and a nice trailer never hurt anything..\n\nAnd top water poppers and hard baits.... poppers for the noise and spooks and torpedos for good action

The answer to that depends on your application, you need to decide whether you want hardness, ductility, hardness, hardenability, or any of a number of other characteristics

Designing one is relatively cheap. Building a prototype is not so cheap. You would need to use precision linear stepper motors or other actuators and their power supplies and  cooling systems and so forth.\n\nI suppose that if you already have a lathe or milling machine you could possibly modify it by replacing the manual positioning and stock feed or tool advance controls with the above computer-controlled steppers, etc. I don't think it would do as good a job as a commercial unit. You would have to have a separate controller for each axis or each degree of freedom that the machine can work in. \n\nHave you tried looking for a used cnc machine that someone might be replacing with a newer unit? It is rare that they would just junk them; you might be able to find a used one or a model that is no longer in production. Try contacting manufactureres. Those are my best ideas, Hope they help.

EDIT: Note additional comment.\n\nWhether you can use a potentiometer depends on the torque availble to turn the shaft.  I would say that in most cases a potentiometer would not react fast enough.  A variable capacitor could work if you could make it small enough and with low friction.  It would help if you gave more information on what exactly you want to measure.\n\n\nEDIT: ADDED COMMENT:\n\nAfter reading your additional explanation, a potentiometer would be the cheapest and easiest solution.  Be aware that most single-turn pots do not cover a full 360º;  if you really need ±180º rotation, you should get a multi-turn pot.  They are much more expensive, but they are also much more precise and repeatable, and also would have much better durability than a carbon-composition or wirewound pot.

A tool is only as good as the operator; no black or white answer would cover all possible factors that would need to be considered - looking forward to reading a good discussion about this subject
