Bills Advice on Turning:
Work from the edge in to the center!
Hold the gouge behind the ferrel.
Use an overhand grip on the steel.
Or grip over top with Index Finger under the steel (Combo-grip).
Place your Thumb on top to relieve fatugue of over grip.
Keep the tool above the centerline of the work.
Keep your body behind the tool rest or you’ll be in the target zone!Make sure the point of the tool has support (some metal from the tool body) below it when cutting.
Project the tool from the tool rest into the work at approximately 10 o’clock.
Glass and Duct tape can be used to remove wood! That is, protect yourself from the glass you are holding with the duct tape, use the glass edge (sharp from being cut from a sheet of glass with a glass cutter), change the glass frequently by re-cutting with glass cutter.
I’m tempted to add: "Do not try this at home!"
Use a SKEW to cut beads in your work. Lead in forward and rotate handle of skew upward to increase depth. Your beads should look like squashed tennis balls! Remember to create some clearance (by cutting down into piece first) before attempting to cut beads.
Use a CURVED GOUGE to make the coves. Start vertical and rotate into horizontal position.
Bill passed around a Scottish Spurtle and a Spatula. He intended to make these, but recognized an accomplished group when he saw one! Therefore, instead of merely tackling the difficult, he launched into the impossible and turned an off-center mock cabriole leg. No words can describe this undertaking, so I will end here, except to say…
Thanks Bill for an excellent presentationNotes and commentary by Richard Derganc, 18JAN01.
