Discount Lee Valley Stronghold Oneway Scroll Chuck Kits

The Stronghold scroll chucks have a nickel-plated body, case-hardened base jaws and a scroll coated with a dry, long-lasting lubricant. Precisely made, the chuck body typically has less than 0.001″ of runout; with the jaws mounted, runout can be expected to be less than 0.005″. Due to their special construction, the jaws can be easily tightened on round or square stock. A stop pin prevents overextension of the jaws. The chucks use a 5:1 ratio chuck key for tightening, ensuring greater holding power on large pieces, and weigh about 8 lb.

The arbor is an adapter that is mounted separately. The unique taper-lock adapter makes the chuck run truer, while guaranteeing safe use of the chuck for right- or left-hand turning. The 1″ × 8 tpi adapter is specially threaded for both inboard and outboard mounting.

Match the kit to lathe brands and their headstock thread size:

• Beaver: 7/8″ × 14 tpi, #1 Morse taper
• Craftsman and Coronet: 3/4″ × 16 tpi, #1 Morse taper
• Rikon, Delta and General 160: 1″ × 8 tpi, #2 Morse taper
• General 260: 1 1/4″ × 8 tpi, #2 Morse taper
• Shopsmith: 5/8″ plain
• Harrison: 1 1/2″ × 6 tpi, #2 Morse taper
• Conover: 1 1/2″ × 8 tpi, #3 Morse taper

If you wish to use the chuck on a different lathe, you need only purchase an adapter separately.

This kit includes a taper-lock adapter, a standard 1 1/2″ woodworm screw, a #2 jaw set, the appropriate levers or chuck key and a hex key. The Stronghold chuck is also available in a body-only version (without jaws, woodworm screw or taper-lock adapter).
