ECCENTRIC ADJUSTMENT BUSHINGS ASSEMBLY. SET-UP AND ADJUCTMENT PROCEDURES Recommend using Weldon style end mill adapter that uses two side locking screws. 1. Scribe line on front face of adapter exactly 90 degrees from locking screws. 2. Load eccentric bushing over drill shank and into adapter lining up the scribed line on adapter and bushing. 3. Before locking the set screws in adapter, line up OD insert in drill with both scribed lines on the bushing and adapter. The drill in this position will drill a nominal (drill size) hole diameter. 4. With the drill and bushing loaded into the adapter and the OD insert in line with the scribed lines, apply the rear set screw (B) in adapter locking the bushing in place. Use only hand pressure to tighten the screw. Applying the set screw to the bushing provides positive axial retention of the bushing and hand tightening allows radial adjustment. 5. Rotate the bushing either plus or minus to desired position then lock the (B) set screw using a wrench. This will lock the radial position setting in preparation for drilling. 6. Lock the front (A) set screw in the adapter using a wrench to lock the drill into the holder. You are now ready to drill. Please check to make sure all screws are tight and assembly is rigid before drilling. Once you produce a hole with the current setting and inspect the diameter, you can repeat procedures #5 & 6 if required to achieve desired diameter. 690
