The Nova Titan Chuck is a four-jaw, self-centering scroll chuck for large lathes with a 20" diameter swing or larger. It is the largest, most ruggedly built chuck in the Nova range - a full 5" in diameter - and provides super aggressive holding power. The TuffLock geared grip provides incredibly smooth operation and vibration free performance. With single-handed operation, you'll spend more time turning and less time setting up. The chuck is operated with an included ball nose hex wrench with a large, easy-grip handle for fast, positive location. The Titan chuck also features a fully sealed backing plate that prevents buildup of wood dust, ensuring minimal maintenance. Includes PowerGrip jaws. 1-1/4" 8-TPI RH thread (dedicated thread only). Recommended for power workholding on lathes with a 20" to 33" diameter swing.Up to 838mm/33" diameter bowls (using PowerGrip jaws).Up to 482mm/19" length spigots (using PowerGrip jaws).Full packaged weight is (std) 3.67kgs/7.93lbs.Solid sheet steel backing plate prevents build up of wood dust, ensuring minimal maintenance.Precise geared grip with Tuff Lock technology delivers incredibly smooth power.Large 5" diameter chuck body is perfect for large lathes and big projects.Single-handed operation means more time spent turning and less time spent preparing.Ball-nose hex wrench with large, easy grip handle for fast, positive location.Body made from precision machined 1045 High Tensile Steel with a polished self metal finish to allow for closer tolerances.Able to take all Nova accessory jaws.Range of Powergrip Jaws: Expansion: 3.740"-4.961"Contraction (square): 2.165"-3.386"Contraction (spigot): 3.031"-4.252".
These machined solid aluminum plates mount to the Oneway Stronghold Chuck (30589, sold separately), and they have a unique combination of slots and tapped holes that accept rubber grippers for holding an infinite number of round, oval or square shapes.Chucking capacities of the Stronghold Chuck with Mega Jumbo Jaws:External (compression): 1-3/4" minimum, 14" maximumInternal (expansion): 4-3/4" minimum, 15" maximumNote: If your lathe has less than a 16" swing, the Oneway Talon Chuck (20761) is recommended. Stronghold Chuck jaws are NOT compatible with either the original Oneway Chuck or the Talon Chuck.
The Robert Sorby TurnMaster is a premium quality modular turning tool that accepts a variety of interchangeable cutters, allowing you to use a single tool for a wide variety of turning projects. The TurnMaster's solid 3/4" steel shank is flattened on the bottom for stability, and the patented TurnMaster head can be rotated to three indexed positions: centered for shaping, and left and right shear for finishing. TurnMaster turning tools are sold with your choice of round, square or detail point cutters in carbide, or a pack of all three in high speed steel. Additional cutters are available in a range of profiles, and in three materials for incredible versatility. For more on the cutter materials, click the "More Info" tab. Each tool ships with Robert Sorby's trademark ash handle installed with a brass collar. If you wish to turn your own handle, TurnMaster Shanks are available separately (e.g. 45649).Technical Details:Patented three-position indexable head can be quickly and easily changed by loosening the locking collar with the included wrench.Head is designed so that all TurnMaster cutters will fit one tool.Additional heads can also be purchased (48797, sold separately) if the user wishes to have a dedicated head for certain cutters.Three indexed positions allow you to go from shaping (centered) to finishing (left or right shear) with a simple turn of the head.Cutters are held in place with a high tensile torx screw which canbe easily removed to change the cutter.Which cutter material should I use?Cutters are available in Tungsten Carbide, High Speed Steel (HSS) and HSS coated with Titanium Nitride ("Excelsior").Tungsten Carbide:Designed to be disposable, these carbide cutters don't require any sharpening. (Carbide tips can actually be sharpened, but require specialized diamond abrasives).Carbide stays reasonably sharp for a longer period of time, but because of its coarse grain, can never be sharpened as finely as HSS.Gives extended cutting life with the toughest of woods.Sharpens to 0.7 - 1 microns.Hardness: 90 RC.Material: micro grade tungsten carbide.High Speed Steel (HSS):Due to its finer grain structure, HSS holds a sharper edge than carbide, but will dull more quickly.Very economical - can be re-sharpened multiple times with standard sharpening equipment.Provides unmatched quality for the discerning woodturner keen on getting the greatest detail from their tools.Sharpens to 0.2 - 0.4 microns.Hardness : 62 RC.Material: M2 HSS.Titanium Nitride (Excelsior):These cutters provide the same advantages as HSS but give added longevity before sharpening is required.No specialized equipment is required for sharpening.Repeated sharpening does not remove the titanium nitride coating, it simply renews it.Sharpens to 0.15 - 0.2 microns.Hardness of titanium coating is up to 85 RC.Material: Titanium nitride coated M2 HSS.How to use the TurnMaster:Set the head in a neutral position so that the cutter is horizontal when the tool is held flat on the lathe tool rest.This is done by loosening the locking collar with the unique wrench and rotating the collar a minimum of two and half turns, which will allow the head to be turned to the required position.Once it is set into the correct position re-tighten the locking collar with the wrench to secure the head into place.To assist with the tightening of the collar, the included small Tommy bar can be placed in the hole situated in the shank to give additional purchase, but please do not over tighten.The tool is now in standard scraping mode.There are three positive stop positions to lock the head for standard scraping, shear scraping to the left and shear scraping to the right.To remove the waste material and to create an initial shape, use either the square or round cutter depending on the shape of the project being turned.Once the required shape has been created, turn the head of the tool to the left or right following the instructions as above.Now the TurnMaster is in shear scraping mode and a more refined shape and finish can be achieved.To ensure the best available finish, always cut with the grain using a freshly sharpened HSS cutter. This will ensure that the grain is sliced to produce a clean surface finish.
