Marc (opfoto): Right now I have two of the HF chucks. I think one was bought on sale. I am very happy with them.
However, I would like to make a comment about drill chucks (Jacobs chucks, as they are called). These chucks are designed for drilling, whether the drill is in the tailstock or headstock.
Any use of these chucks where there is pressure applied from the SIDE or away from the taper will tend to dislodge the chuck. For example if you are using it to hold a bottle stopper.
In such cases it is advisable to get a taper that has internal threads in the small end. These threads are usually 3/8"-16. You use a piece of threaded rod from the taper to the outside of the spindle or tailstock, and secure it with a washer and nut (nylon wing nut in my case).
www.littlemachineshop.com sells these tapers, and chucks to go with them. You can get a chuck and taper combination for about $18 plus shipping. The tapers are Morse in one end, and either 2JT or 33 JT in the other. The chuck itself has to match the JT (Jacobs taper that goes inside the chuck.
If you want to get this kind of chuck, I highly advise to look at the site and then call Chris on the phone. He will make sure you get what you need.
The drawbar is there to hold the taper in place. You don't have to tighten it beyond finger tight.
