Installation Instructions for Mounting Back Platesonto SpindlesAll Bison semi-machined and fully machined backplates will have the mounting dimensionsfor their respective spindles fully machined. The fully machined backplates are designed forscroll plain back chucks, which are .030", etc. They can be used on other styles/models,but the existing bolt hole patterns have to be reviewed for mounting interference.
In all cases, the backplates will have to be finished/machined on the mounting projection,both on the OD (approximately .030" oversize) and the length.
1. With an indicator check the spindle to see if there is any radial or axial runout.Refer to the chuck manual for spindle nose accuracy.
2. Wipe the protective factory grease off the backplate, then mount it to therespective spindle making sure that all fastening components aretorqued appropriately.
3. When initially installing the bolts, leave finish tightening to a second pass,and make sure to alternate to the opposite bolt to evenly distribute pressureacross the spindle’s taper. Using the dial indicator, recheck the radial and axialbackplate runout. If there are major differences, loosen the backplate and refit it.
4. Once the backplate is in place, a technique used to further ensure a closetolerance to the chuck would be to blue the front face of the backplate andtake a skim cut. In most cases this is not required.
5. Next, measure the OD and depth of the counterbore on the backside of thechuck; these will become your working dimensions for final sizing. Dependingon the size of the chuck, the OD should be .001" to .005" less than the ODdimension and the length can be approximately .015" to .030" shorter. Thisminus tolerance will eliminate the possibility of the projection pressing againstthe back of the chuck, which can impact the scroll and create unnecessaryfriction with the jaw teeth. This could make it difficult for the wrench to turnthe pinions and in turn the jaws. Machine the backplate until a snug fit has beenachieved; this may require removing the backplate.Note: The purpose of this backplate projection to the chuck counterbore is to relievethe stress on the mounting bolts, and is a critical part of maintaining chuckconcentricity.
6. The semi-machined backplates recommended for independent chucks donot have mounting holes, and will have to be machined to the chucks bolthole pattern. Dimensions are available in the BISON catalog, online athttp://www.toolmex.com/learn-more/online-catalogs.cfm, or by calling a customerservice representative at 800-992-4766 or 508-653-8897.
7. Bolt hole patterns may require removal of the backplate for machining. Oncemachined, follow the procedures from steps 2 and 3 before mounting.
8. Re-indicate the chuck for basic run out on the OD and Face.9. Take a round piece of ground stock and enclose the jaws. Then, indicate the
part for runout at the jaws, half way across its length, and at the end. This will giveyou an idea of the parameters that will have to be accounted for in part production.

Installation Instructions for Mounting Back Platesonto SpindlesAll Bison semi-machined and fully machined backplates will have the mounting dimensions for theirrespective spindles fully machined. The fully machined backplates are designed for scroll plain back chucks,which are .030", etc. They can be used on other styles/models, but the existing bolt hole patterns haveto be reviewed for mounting interference.
In all cases, the backplates will have to be finished/machined on the mounting projection, both on the OD(approximately .030" oversize) and the length.
1. With an indicator check the spindle to see if there is any radial or axial runout.Refer to the chuck manual for spindle nose accuracy.
2. Wipe the protective factory grease off the backplate, then mount it to the respectivespindle making sure that all fastening components are torqued appropriately.
3. When initially installing the bolts, leave finish tightening to a second pass,and make sure to alternate to the opposite bolt to evenly distribute pressureacross the spindle’s taper. Using the dial indicator, recheck the radial and axialbackplate runout. If there are major differences, loosen the backplate and refit it.
4. Once the backplate is in place, a technique used to further ensure a closetolerance to the chuck would be to blue the front face of the backplate andtake a skim cut. In most cases this is not required.
5. Next, measure the OD and depth of the counterbore on the backside of thechuck; these will become your working dimensions for final sizing. Dependingon the size of the chuck, the OD should be .001" to .005" less than the ODdimension and the length can be approximately .015" to .030" shorter. Thisminus tolerance will eliminate the possibility of the projection pressing againstthe back of the chuck, which can impact the scroll and create unnecessaryfriction with the jaw teeth. This could make it difficult for the wrench to turnthe pinions and in turn the jaws. Machine the backplate until a snug fit has beenachieved; this may require removing the backplate.
Note: The purpose of this backplate projection to the chuck counterbore isto relieve the stress on the mounting bolts, and is a critical part in maintainingchuck concentricity.
6. The semi-machined backplates recommended for independent chucks do not havemounting holes, and will have to be machined to the chucks bolt hole pattern.Dimensions are available in the BISON catalog, online at www.toolmex.com,or by calling a customer service representative at 800-992-4766 or 508-653-8897
7. Bolt hole patterns may require removal of the backplate for machining. Oncemachined, follow the procedures from steps 2 and 3 before mounting.
8. Re-indicate the chuck for basic run out on the OD and Face.9. Take a round piece of ground stock and enclose the jaws. Then, indicate the
part for runout at the jaws, ½ way across its length, and at the end. This will giveyou an idea of the parameters that will have to be accounted for part production.

Principal Mounting Dimensions for Bison Adapters
Type 8205
• After selecting a suitable backplate for the lathe, mount it onto the spindle nose of the lathe• Proper mounting is very important in order to secure concentricity between the lathe’s spindle and the chuck• The back of the lathe chuck has a counterbore diameter, E, finished in H7 class, with depth, C• Prior to maching the adapter, accurately measure the chuck’s counterbore diameter, E, and depth, C• A good press fit, H6/k5, is most desirable• To ensure satisfactory concentricity, it is important that this procedure is done accurately
* S = length of the boss of the supplied backplate** Sx = length of the boss after machining

* Backplate OD has to be turned down to fit chuck counterbore
See pages 84 and 85 for plain back chuck dimensions
Chuck and Back Plate Selection InstructionThe back plate OD (size A) should match the plain back chuck counter bore diameter (size E), see pages84 and 85. Check the back plate thru hole diameter (size C) and compare it with the chuck bolt circlediameter (size F). Be sure that you have enough room on the back plate body to drill and tap the chuckmounting holes. In the case of “A”, “D”, and “C” back plates, be sure that the chuck mounting bolts willnot interfere with the spindle mounting bolts or camlock studs (diameter D). It is recommended that theplain back chuck bolt circle diameter (size E) be larger than the spindle mounting bolt/camlock stud circlediameter (size D).
