Sorby RSPCN34 Patriot Chuck, M33 x 3.5. Drawn from many years of experience in selling, marketing and distributing another brand of chuck, the design of the Robert Sorby RSPCN34 Patriot Chuck M33 x 3.5 incorporates all the key features which turners look for in a scroll chuck. Because they started with a blank slate, Sorby determined that there were to be no compromises in the design.
This 4 jaw chuck is compact in design so it won't strain lathe bearings, yet it is ideal for all sizes of projects. It uses a spindle insert system (although this particular chuck has a dedicated M33 x 3.5mm insert) so there are sizes available to fit most commonly used lathes.
The single key operation with positive location, teamed with true compression angles on drive and driven gears, smoothly and easily opens and closes the jaws in unison. The key is also articulated to allow access behind large projects. Jaws stops prevent the slides from working loose.
The body of the chuck has an enclosed back to protect gearing against dust but, should you need to, the back plate is removable for easy maintenance and cleaning. A unique silicone safety band on the rim helps to protect turners from injury caused by contact with the outer edge of the chuck while it is rotating.
With a wide selection of useful, perfectly matched jaws from which to choose the Patriot chuck gives additional versatility and ease of use. The jaws are dovetailed on the inside and outside face and additional serrated teeth on jaws give extra grip.
The Patriot M33 model has been specifically designed and machined to work with lathes with an M33 X 3.5mm spindle, and also have the reversing option. It will work in either forward or reverse modes. Chuck is 4" in diameter and weighs approximately 4-1/2 lbs. Made in Sheffield, England.
