North East Chapter – Irish Woodturners Guild

June 2015

 

Michael Fay, Dublin Chapter, was our guest demonstrator at our June meeting. His project was a ‘Crush grind pepper mill’, turned from a 300 mm x 75 mm piece of air dried Oak. Precise measurements throughout being critical to house the internal mechanism and the smooth movement of the grinder.

Mount blank between centers and form a 60mm spigot which will be the base.  Turn a tenon at top of grinder (tailstock end), and mark at 170 mm up from the base – cut off base at this point.    Remount base in chuck and clean top.  Bring up tailstock and cut tenon at top of the base.  Reverse chuck to work on base.  Start drilling base with 45 mm drill for say 5 mm, switch to 25 mm drill to an o/a depth of 55 mm.  Revert to the 45 mm and re-drill to the 55 mm depth.  Cut a shallow inside groove at the 55 mm depth: this is achieved with a homemade tool – using the top of a steel bolt ground with sharp square corners.  Reverse chuck to work on top of the base.  Using 38 mm bit drill to 15 mm depth.  Return to the 25 mm bit and continue to drill to meet the original opening.  Revert to the 38 mm bit and re-drill this opening. 

 

Mount the top section in chuck and using a 22 mm bit drill to a depth of 50 mm.  Cut tenon 35 mm x 10 mm deep to fit into top of grinder. Safety tip - when using calipers to mark the required diameter – only engage side nearest to you to make the mark.  Using the specialized grooving tool, cut a 12 mm groove beyond the 30 mm dept. 

 

Remount full grinder between tailstock and chuck & shape the outside profile using a spindle roughing gouge.  Finish with Danish oil and carnauba wax.  Finally, assemble be pressing fittings onto position.  Thanks Michael for a well researched, exacting and competent presentation.
