MCW Aug '10 "Demo" (Tips 'n' Tools)
Aug 29, 2010Public
Photo: Bert Bleckwenn brought a screw chuck, of Al Stirt design, that has two adjustable points on the edge, which allows minor repositioning of a blank or a rough-turned bowl to allow for the optimum grain pattern in the bottom of the bowl.
Photo: Terry Lamb, with encouragement from his brother, Peter, made an assortment of four tools and used them to turn a couple small hollow forms.
Photo: Michael Blake brought an assortment of homemade tools.
Photo: Elliot Schantz made a large rear hollowing bar stabilizer, ala Lyle Jamieson.
Photo: Michael Colella showed a roughing tool, made from 5/8" bar with ¼" tool steel bit in bought (Trent Bosch) aluminum handle.
Photo: Clif Poodry brought an off-center chuck for making jewelry.
Photo: Bill Autry made a chucking system for turning napkin rings. A larger version will work for bracelets.
Photo: Tim Aley made a large "modular faceplate system" (aka donut chuck) to finish the bottoms of bowls directly, without impediment.
Photo: Ilya Zavorin brought a can of Clapham's Beeswax Salad Bowl Finish, a soft mixture of beeswax and mineral oil. It is easy to apply with a piece of cloth, and fast rubbing into the wood by hand does the job, followed by vigorous brushing with a shoe brush made from natural hair (a MUST). Several coats may be applied. The result is very nice matte finish.
Photo: Gary Nickerson made a leveled jig to set his grinding wheel exactly 7" from the notch and 4" high, for using an Ellsworth sharpening jig with the Ellsworth Signature gouge. He brought a picture of his grinder set up to show how the jig works.
Photo: Carl Powell brought a 5/16" tri-point tool in a quick-change handle made like a collet chuck closed by a hose clamp. He also showed two 5/16" nuts -- drilled out to accept the 5/16" bit and drilled and tapped for set screws to hold it in place -- used to grind the angles of the tri-point tool exactly 120 degrees apart.
Photo: Steve DiBenedetto made a complete sharpening system, ala Oneway Wolverine, out of wood.
Photo: Ed Karch constructed a grinder hanger out of a bamboo tube mounted on the wheel assemby from a desk chair.
Photo: Phil Brown shows a cone-shaped chuck for holding a deep vessel, with no pressure on the rim, while removing the shoulder and chuck marks and touching up the bottom-resting surface. The padded centering ring holds the rim in place. Tall vessels with narrow bases may also need an internal support.
Photo: Jack Enders made two simple and primitive scratch-built micro gouges/scrapers from nails. These are used for intricate grooving and undercutting on bottle stoppers. He ground a tiny cutting edge on the sharp end of a common 10d nail for one of them. For the other, he ground the head of an 8d wrought iron nail to a 'curl' shape for scoring and undercutting. The wrought iron nail is epoxied into a hole drilled endwise in a 3/4" dowel for a handle. He doesn't need a handle for the common 10d nail. His point is that you can quickly do 'one-off' tools like this for special needs, as necessary -- you don't have to worry about long-term life of a tool like this, and the investment is miniscule.
Photo: Gary Guenther brought an a bent hollowing tool mounted with an “outrigger” (aka “torque arrestor”). (This one was made by CA Savoy.) This is an inexpensive method for stable, comfortable, safe blind hollowing.
