Fully machined back plate can be mounted onto 5" 3 jaw or 4 jaw self centering lathe chuck (p/n 202-5594). As long as back plate Shoulder Diameter 3.78"> chuck's D1, all 5" chuck will fit in. 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. D1 need to be processed before back plate can be mounted. 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 Lathe Lathe Chuck Diameter BRAND MODEL SWING SPINDEL THREAD 3" 4" 5" 6" ATLAS 6" 1/2"-20 202-6231 ATLAS 10100 6" 1"-10 202-6107-6, 202-6107-3 ATLAS TH42 10" 1 1/2"-8 202-6230 202-6108-6, 202-6108-3 202-6192 202-9106, 202-6119 ATLAS 5991 12" 1 1/2"-8 202-6230 202-6108-6, 202-9108-3 202-6192 202-6109, 202-6119 ATLAS 3986 12" 1 1/2"-8 202-6230 202-6108-6, 202-6108-3 202-6192 202-6109, 202-6119 EMCO MAIER MAXIMAT V10 5" M39X4MM 202-6214 202-6215, 202-6217 GRIZZLY G8688 7" 3" FLANGE GRIZZLY G4000 9" M39X4MM 202-6214 202-6215, 202-6217 HARBOR FREIGHT 33684 7" 3" FLANGE HARBOR FREIGHT 45861(BV20) 9" M39X4MM 202-6214 202-6215, 202-6217 HOMIER 03911 7" 3" FLANGE JET 920N 9" 1 1/2"-8 202-6230 202-9108-6, 202-6108-3 202-6192 202-6109, 202-6119 KING CH-920 AG 9" M39X4MM 202-6214 202-6215, 202-6217 LOGAN 9" 1 1/2"-8 202-6230 202-9108-6, 202-6108-3 202-6192 202-6109, 202-6119 LOGAN 10" 1 1/2"-8 202-6230 202-9108-6, 202-6108-3 202-6192 202-6109, 202-6119 LOGAN 11" 2 1/4"-8 202-6234 202-6110, 202-6120 LOGAN 12' 2 1/4"-8 202-6234 202-6110, 202-6120 LOGAN 6510/6560 14" 2 1/4"-8 202-6234 202-6110, 202-6120 MICRO-MARK 82710 7" 3" FLANGE MICRO-MARK 82500 7" 3" FLANGE SEARS 101.07301 6" 1"-8 202-6106-6, 202-6106-3 SEARS 101.2899 12" 1 1/2"-8 202-6230 202-6106-6, 202-6106-3 202-6192 202-6109, 202-6119 SHELDON WM-46-P 13" 2 1/4"-8 202-6234 202-6110, 202-6120 SHERLINE ALL 3.5" 3/4"-16 202-6212 SIDNEY MACHINE LOT 160 14" 2 1/4"-8 202-6234 202-6110, 202-6120 SOUTH BEND CL187ZB 10" 2 1/4"-8 202-6234 202-6110 Related products 5" Fully Machined Threaded Back Plate 1-1/2"x8 p/n: 202-6192 5" Fully Machined Threaded Back Plate 2-1/4"x8 p/n: 202-6234 5" Fully Machined Threaded Back Plate 1"x10 For p/n: 202-6261 elated products 5" Adapter Back Plate D1-3 p/n: 202-6121 5" Adapter Back Plate D1-4 p/n: 202-6122 SKU 202-20313/8" Self-Ejecting Lathe Chuck Key click here to visit my Ebay store now 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.
