Truly remarkable. I have 3 college degrees and I greatly admire the acumen level displayed by so called "blue collar" workers. It definitely rivals people with degrees, as many I know that've gotten through college are dolts.

You would need a chuck with t-slots cut into it between the jaws. Weights are added to the slots and moved towards/away from center to find balance. I've been fortunate to work with some really gifted people and I've learned a lot. Young people have a lot to teach with technology as an example. I always tell my students "we are all teachers". Thank you for your kind words.

Little trick I use is to chuck up the dead center in the tail stock, lock the stock, and while holding the plate, with the jaws open enough where they don't interfere, introduce pressure with the tail stock until it presses the metal plate against the jaws. You then lightly tighten the jaws, and proceed exactly as you did. The advantage is, it gets you a lot closer to center quicker, making less adjustments to the jaws. Just a time saver.

Use a lever type dial indicator and adjust hole towards the center by halving the total reading. You can get it very close to true by using the center (light pressure) to hold the block when you start and then bring the jaws in until it touches the block. Then use lever type dial indicator for final setting. Always works and is quick!

Put your lathe in neutral the chuck will rotate to the heavy side...6 o'clock. Add the weight at 12 o'clock. I drill a hole in round stock maybe 3 inch dia. 2- 3 inches long (depending on how heavy your part is) slide it over a t- nut and stud and tighten a nut on the other side. Move the weight towards and away from center until the part will not move in any position in 360 degrees. It should be balanced. Watch your rpm, it is not meant to turn fast. Watch your fingers there is a lot going on with that chuck face. Good luck.

Best Racing Tips Win At The Dragstrip Hi Tommy, most 4-jaw chucks have elongated slots on the face to take t-nuts (not this chuck). The easiest way is to face a short length of round stock and drill a hole through the center. Place the stock over the stud and t-nut and hold it tight with a nut. The stock should be opposite the offset of the material being machined (square plate in this case). The elongated slots allow the stock to be moved towards/away from chuck center to find the balance point. Thanks for the question, hope this helps.
