Detailed Description

Oneway Stronghold Scroll Chuck

Oneway's Stronghold Scroll Chuck offers powerful and versatile self-centering stock holding with their jaws that expand within a shallow undercut recess to grip the bottom of a bowl securely, or tighten around a foot, stub tenon or the end of a spindle. A variety of optional jaw sizes gives this large chuck a wide grip range; holding round or square tenons from just 3/8" (with Spigot Jaws) to 14" diameter with Maga Jumbo Jaws. The standard #2 profile jaws the Stronghold chuck comes with have an external capacity of 2" to 3-1/2" and an internal capacity of 2-5/8" to 4-1/8". It also includes a 1/2" x 1-1/4" Woodworm Screw, whose deep, sharp threads & tapered nose are bite and hold exceptionally well. The Woodworm screw installs easily and securely into the chuck.

The Stronghold chuck uses a large T-handled single chuck key to move the jaws in and out. The chuck key lets you single-handedly tighten and loosen the jaws so your other hand is free to support and hold the stock.

The Stronghold Chuck is the largest chuck Oneway makes. Its size makes it a good partner for larger lathes. The body of the chuck is 4-1/2" in diameter and weighs 6.75 lbs. Threaded taper-lock mounting adapters, available to fit a wide variety of lathes, center themselves perfectly in the chuck body, which can then be screwed onto your lathe's spindle nose. An adapter is required for the chuck. Extra adapters offer a very economical way to use the same chuck on every lathe you own. Only the Stronghold Chuck by handles 1-1/2"- 8 tpi mounting adapter sizes.

For all spindle sizes, a threaded insert is REQUIRED to adapt the chuck to fit your lathe. See the chart below for the sizes available. If you do not see your size call us for assistance. If you choose to order this chuck without an insert and you do not already have an insert, it will not work.
