Product features Made from high grade cast iron Fits most 8″ self centering plain back chuck (please verify the bolt circle diameter and shoulder diameter on the back of the lathe chuck) How to process back plate to guarantee Chuck’s T.I.R? The fully-machined chuck back plates can be mounted onto 8″ 3 jaw or 4 jaw self centering lathe chuck (p/n 202-5412, 202-5434, 202-5474, 202-6189). All back plates have 0.04″ allowance, please measure the size of Chuck’s D1 before process your back plates. The size of back plates’s D1 should be a little bit smaller than the size of Chuck’s D1. Because the gap between back plate and chuck is smaller, chuck’s TIR is better. No gap is the best. You would not need to drill any mounting holes but you will need to turn the shoulder down .040″ to match the back of the lathe chuck to make the chuck & back plate more concentric with the lathe spindle. When turning the shoulder of the backing plate, ONLY TURN THE SHOULDER OF THE BACKING PLATE WHEN ATTACHED TO THE LATHE SPINDLE. If you use a chuck to clamp the backing plate and then turn it, the backing plate will not be true to the lathe spindle and will have more runout than specified when the chuck and back plate are put together. The back plate may come with two or three additional screws (depending on type) for removal the back plate from the chuck. They are not used to mount the chuck to the back plate, mounting screws should be included with the chuck Product includes 3 pcs of studs for mounting into the cam lock on lathe spindle We have other chucks & back plates available at My Ebay Store : Related products 8″ Fully Machined Threaded Back Plate with 1-1/2 x 8 TPI for 3 or 4 Jaw Self Centering Lathe Chucks p/n: 202-6201 8″ Fully Machined Threaded Back Plate with 2-1/4 x 8 TPI For 3 or 4 Jaw Self-Center Chuck p/n: 202-6202 8″ Semi-Machined Threaded Back Plate with 2-3/8″- 6 TPI FOR 8″ 3-JAW AND 4-JAW LATHE CHUCKS p/n: 202-5900 Related products THREADED BACK PLATE 8″ Semi-Machined 1-3/4-8 TPI FOR 8″ LATHE CHUCK p/n: 202-6161 8″ D1-3 Fully Machined Back Plate For 8″ 3 and 4 Jaw Self Centering Chucks p/n: 202-6153 8″ D1-4 Fully Machined Back Plate For 8″ 3 and 4 Jaw Self Centering Chucks p/n: 202-6154 Related products 8″ D1-6 Fully Machined Back Plate For 8″ 3 and 4 Jaw Self Centering Chucks p/n: 202-6155 8″ D1-5 Lathe Chuck Adapter Plate Semi-machined for 8″ Plain Back lathe chuck p/n: 202-5455 SHARS 7/16″ Self-Ejecting Lathe Chuck Key p/n: 202-2032 SHIPPING: UPS Ground Buyer pays ACTUAL UPS shipping & insurance, and a $3.00 handling fee for this item to be shipped to all states within the continental United States.
