139.4 Index pinRefer to Figure 16.Indexing is used to create evenly spaced featuresin a work piece, while keeping the lathe spindlelocked; for example, when cutting flutes on aspindle blank with a hand-held router, while thespindle blank is secured between lathe centers.Your lathe provides 24 indexing positions. Theseare identified by inscribed numbers on the spindlepulley (H, Figure 15)Figure 161. Rotate spindle until index pin (J) aligns withdesired hole.2. Push index pin into hole and rotate knurledhead (K) to engage threads and secure inposition.3. Perform operation.4. Rotate knurled head counterclockwise until pinreleases. Move pulley to next desired hole,and repeat. NOTE: A 3mm hex key can beinserted and turned in the hole of the knurledhead, to help tighten or loosen the index pin.Disengage index pin beforestarting lathe.IMPORTANT: Do not use index pin to lock spindle,which will cause unnecessary wear to the pin. Useknockout rod in hole of spindle collar for thispurpose.10.0 Operating controlsRefer to Figure 17.On/off switch (A): Pull up to start lathe, push downto stop. The safety key (A 1 ) can be removed toprevent unauthorized use of lathe. Key must bereinserted to start lathe.Speed dial (B): Rotate clockwise to increasespeed, counterclockwise to decrease. [JWL-1015VS only]LED light (C): Displays green during normaloperation of the lathe. If the lathe stops, and theLED displays red due to overloading, push and pullswitch to restart. [JWL-1015VS only]Do not start lathe at maximumspeed. Start at lowest speed within that rangeand gradually increase to full speed.Figure 1711.0 OperationThe information which follows is general in natureand is not intended to be a complete course inwood turning. Nothing can replace the knowledgegained by conversation with experiencedwoodturners, or consulting books or trade articles.Above all, simple trial and error will aid indeveloping proficiency in the craft.11.1 InspectionBefore operating the lathe, check that everything isin proper working order:1. Machine is on a level surface.2. Check bearings; adjust only if endplay exists.3. Check belt; it should be snug but not overlytight.4. Bed ways; keep clean, use steel wool toremove any rust spots, and apply paste wax toprevent buildup of rust and finishes.5. Tool support; use a mill file to remove nicksand dings.6. Spindle tapers; should be clean and free ofdust and chips for proper seating of tapers.7. Tailstock; clean and lubricate quill and lockingdevice.8. Lighting; proper lighting is essential toeliminate shadows and reduce eye strain.
