I want to make my drill press variable speed, like my hand held VSR drill.?

Hand-held VSR drills use a geared motor to vary the speed. A drill press with a belt system uses a single speed AC motor and a system of different sized pulleys to vary the speed. If you want to vary the speed without moving the belt, you'll have to do it electronically.\n\nThere are speed controllers for AC motors on the market. Here's a link to a footswitch type.

Speed control in industrial drives can serve several purposes.  The VFD (variable frequency drive) or VSD (variable speed drive) can control the RPM of a motor which drives a fan, pump, conveyor belt or other machine.  The advantage of using speed controls is that the speed of the machine can be matched to the need, can be automatically controlled through feed back loops, and also the VFD/VSD controlled motor will use significantly less energy than a similar system using a bypass loop to bleed energy from the pump or fan system.

You want to use a 23/32 .718 drill bit.\nStart by spot drilling with a 1/4 or so then drill with the .718 bit.

Pretty simple. If you are going to employ a variable frequency drive or inverter to vary the motor speed you must then select an inverter duty motor. The reason is because motors are designed to cool themselves while running. Conventional motors are designed to dissipate heat at full speed (60 Hz). If a conventional motor ran at lower speeds then eventually it would get too hot causing insulation breakdown and then.....bad things happen. \n\nInverter duty motors have more insulation and can therefore handle the heat at slower motor speeds.

it is under Dodge tool. Or you can use Shift+O to cycle through Dodge, Burn and Sponge tools.

Hey lets make it simple...\n\nwhenever u use only proportional controller and tune it to good gain then also u will have an offset error i.e ur Process value will never reach the setpoint, so if u introduce I (Integral) controller it will reduce this offset error or even makes it zero, but u gota tune it porperly, If u increase more time valve of I controller they system will become slow so be care ful if want more details then refer to  http://en.wikipedia.org/wiki/PID_controller

Try the following,\n->start\n-->control panal\n--->mouse\n---->pointer options tab\n----->increase the pointer speed settings.

You should use pulse width modulation (PWM).  PWM is essentially an on-off sequence in time, like a square wave alternating between 0 and 1.\n\nClearly full voltage will give you maximum speed.  This happens when the voltage is always on.  Now, suppose you only wanted to go half the maximum speed.  You could send a a square wave with 50% duty cycle (on half the time and off half the time) at high enough frequency that the motor will spin at a constant 50% maximum speed.  The motor is like a lowpass filter and therefore, a square wave at high enough frequency will produce a steady response without oscillation.\n\nIf you want the motor to go slower, say, at 25% maximum velocity then send a pulse that is on 25% of the time and off 75% of the time.\n\nIn reality, if you want 25% speed you may have to send something like a 27% duty cycle because of the time delay between commanding 'on' and the system actually turning 'on'.  In this application, though, I don't think you will have this porblem.

drill it out and use tap die to re due new threads

Go under Nividia mixer and there you can control the volume and other things

you need to regulate 12 v down to 5v.\n\nYou could use a common 555 timer, and adjust the delay with a potentiometer for the Resistor in the RC network.

put an arm perpindicular on the shaft, put another arm pinned to the first, and slide the second through a sleeve.\n\njust like an old fasioned steam engine turned linear movement (piston) into rotary(drive wheel
