Since Paul was unavailable this week Duncan donned his double duty hat to both run the meeting and do the demo. Thanks Duncan for stepping up.
Among the twenty-five members who showed up for the March meeting were some of the returning Snowbirds. Welcome back.
Duncan reminded everyone that the deadline for early bird registration for the 2018 Symposium is the end of March. If you are thinking of coming do yourself a favor and register now:
If you are coming to the Matisho turning event this weekend please read and sign the insurance waiver. You can download and print a copy HERE.
Thanks Duncan for preparing all the information and showing us various techniques for holding items on the lathe.
Duncan is a big fan of using a vacuum chuck and he has developed inexpensive aids to make this possible. Using a tap with the same thread as your headstock it is easy to make a substitute for a metal faceplate. With this technique you can adapt any number of sizes and shapes of vacuum chucks to hold your work. Duncan uses plastic piping fastened to the wooden faceplate with Gorilla glue and turns the edge round to attach a piece of foam sheeting from Michaels or the dollar store.
Well worth the price of admission was this jig Duncan developed. He wanted to maximize the piece of expensive hardwood so he could make a lidded box. Cutting a piece off the already round wood is a dangerous operation on a bandsaw. Duncan solved this by cutting a hole in a piece of scrap plywood at the correct distance from the edge to hold a chuck so the wood is parallel to the bandsaw blade. A bolt is then threaded into the chuck and tightened. This arrangement then holds the wood solid and prevents rotation as you saw the piece off. It also has the exhilarating effect of keeping your fingers a long way from the saw blade.
This is fantastic Duncan.
In this picture you can see a use for the flat sanding disc described earlier. Duncan makes urns and after gluing up the tapered staves he needed a way to create a tenon on the bottom which is then grasped with #3 jaws on a Talon chuck and allows finishing the inside and outside. The sanding disc provides a solid non slip surface to hold the large end of the urn. An adapter (available from Lee Valley or Oneway) allows a chuck to be fastened onto the tailstock and precisely advance the cone to secure the urn between centers and turn a tenon.
Thanks Duncan for a very practical, informative demo.
Show and Tell.
Gus showed us the evolution he has gone through using split and reverse turning techniques to come up with some interesting shapes. He uses hose clamps a lot to hold the pieces in place while turning.
Dean explained how he made the maple and Ash bowls.
Cal used epoxy with black coloring to hold the two pieces of this maple bowl together while he turned it.
Cal uses some ingenious methods to create these off centered bowls. Be ready for some challenges with vibration as you turn these!
Steve made this lovely Ash bowl from a local tree. He explained how Ash can be difficult to work with as it is prone to forming cracks.
Gary showed us a bowl that provided numerous challenges along the way from cutting down to finished product.
This piece was intended to be a bowl but Gary felt it really wanted to become a box so he made a lid with a carved rabbit for the top.
