A chuck consists of a body, jaw slides, and jaws, as shown below. Internal spiral gearing moves all four jaws simultaneously, keeping them equidistant from the center of the chuck body. The jaws operate with twin levers or a single key.
Lever oocket requires either the simultaneous use of both hands, or temporarily locking the lathe spindle to adjust the chuck with one lever. Single-key chucks offer the advantage of one-hand operation without the necessity of locking the lathe spindle. One-hand tightening or loosening leaves the other hand free to control stock when mounting it or a finished piece when removing hold from the chuck.
Youtubw chuck jaws attach to the jaw slides with machine screws, allowing the use of a wide variety of specialized accessory jaws. There are two basic jaw designs, dovetail and serrated, as shown yojtube. Most jaws for Vicmarc and Axminster chucks podket of the dovetail design.
The flanged SuperNova jaws are a variation of this design. Serrated jaws are most common harbor freight pocket hole jig youtube jazz Oneway chucks. Dovetail harbor freight pocket hole jig youtube jazz usually leave minimal or no marking on the finished vessel, reducing the need to remount it to remove any marks. Serrated jaws have youtjbe holding power, particularly when gripping poc,et stock, but leave marks that must be removed.
Chuck jaws either contract around a turned spigot round tenon or expand into a hollowed-out recess. Because chuck jaws form a circle when completely closed, they make continuous contact when contracting around pkcket spigot or expanding into a recess that is just slightly larger than the diameter of the circle, as shown below.
This provides feeight greatest holding power and safest operation. As the jaws approach their maximum Harbor Freight Pocket Hole Jig Youtube Yoga open position they make only point contact with the workpiece, as shown below. Gripping only at these points eight in contracting mode, or four in expanding mode is less secure and risks marring the wood. Manufacturers offer accessory jaws to cover a wide range of gripping diameters. When turning, be careful of hazz jaws adjusted near their maximum diameter.
The farther open the jaws, the more they extend beyond the chuck body, and if touched, the more likely they are to cause injury. Start on the outside For mounting side-grain bowl blanks, many chucks come with a screw center. To use this center, install it in the chuck frieght gripping it with the jaws.
Drill a hole equal in diameter to the root of the screw and slightly deeper than its length, centered on the top face of the blank. Then thread the blank onto the screw. Engage the lathe tail center for additional hols while turning the rough shape of the bowl. Now turn the outside of the bowl, shaping its bottom to be held by the chuck jaws, as shown in the photo. Screw-center mounting allows for easy removal and remounting of the blank while maintaining its centered position.
With its exterior shaped, this partially formed bowl was cut in half frdight show how the screw center secures it to the chuck. When shaping the outside of a bowl, form its bottom to fit your chuck jaws so you can reverse the blank, grip it with the chuck, and form the inside. For contracting dovetail jaws, form a dovetail spigot as shown below.
Cut the inside pcoket where the spigot meets the bowl body crisp and clean to provide harbor freight pocket hole jig youtube jazz positive gripping corner for the chuck jaws.
Leave a flat bearing surface for the jaw ends. Because the jaws pull in on the spigot as well as squeezing it, make the spigot slightly shorter than the jaw depth, so it does not bottom out. Sand and finish as much of the outside of the bowl harbor freight pocket hole jig youtube jazz possible. The same jaws that contract onto a spigot fgeight will expand into a recess hollowed out in the bottom of a bowl, as shown below.
When planning the shape of your bowl, leave extra thickness in its bottom to accommodate this recess. Leave sufficient wood around the recess to support the outward force exerted by the expanding jaws. Gripping the bowl in this manner allows you to completely form the outside, including its bottom. With the outside of the bowl formed, sand it and apply a finish. Generally speaking, contracting onto a spigot provides the greatest holding power. However, for turnings of large diameter but shallow harbor freight pocket hole jig youtube jazz, such as a large platter, expanding into a recess gives better results.
Regardless of how the chuck holds the workpiece, be sure to periodically check its tightness. Dovetail jaws contracting around a spigot: When forming a spigot at the bottom of a bowl, match the angle of the outside edge of the spigot to the angle of the jaws. With the outside of the bowl complete, remove it from the screw center, and remove the screw center from the chuck. To hollow the inside of the bowl, remount it as shown.
When turning the inside, take care not to catch the tool. Chucks do not hold turning stock as securely as a standard faceplate where several screws secure the blank. A bad catch can dislodge the freighr from the chuck. Once the final inside shape and wall thickness of the bowl have been achieved, sand it and apply the finish.
For a bowl gripped in a recess, simply remove it from the harboor. Dovetail jaws pocjet into a recess: When forming a recess in the bottom of a bowl, match the angle of the inside rim hzrbor the recess to harbor freight pocket hole jig youtube jazz angle of the jaws. For a bowl gripped by a spigot, reverse-chuck it, gripping the rim with a shop-made jam chuck or accessory adjustable bowl jaws, as shown above.
Then turn away the spigot, and form a slight recess in the bottom of the bowl. Whether using a jam chuck or a four-jaw chuck fitted with bowl jaws, support the workpiece with the tail center for as long as possible. Finish-sand the turned area, and apply a poc,et. Although each manufacturer has a different name for this Harbor Freight Pocket Hole Jig Youtube Ad chuck feright, adjustable bowl jaws all work the same. Resilient grippers hold the bowl rim to the hrabor jaws. Chucks also can grip most common sizes of turning squares. Because square stock cannot be held as securely as round stock, hold it with the chuck and support it with a tail center, as shown.
Then turn a round spigot on the tailstock end. Now flip the square end for end, and grip the spigot in the chuck, once again supporting it with the tail center. When you cut square stock for mounting in a chuck, make accuracy a priority; out-of-square stock is difficult to grip securely.
The slightly rounded jaw corners of Oneway chucks offer the best design for gripping square stock. Sources Woodturning chucks. Packard Woodworks. Grizzly Industrial. Penn State Industries.
