2 Chips & Bits September 2017 After all is said and done with Hurricane Irma, I think we can all say we really dodged a bullet with this storm. Still early in the season so I hope other potential threats blow the other way. With disasters come benefits and for woodturners there s nothing like a good blow to take down some choice trees for our addictions. The Florida Rosewood that came down in Venice was a prime example. Just ashamed it had to also take down an entire pool cage with it. Now s the time though to scour the neighborhoods for some choice wood before it goes to the chippers at the landfills. Hope to see some nice show & tell projects along with an Irma story to maybe go with it. The October 5th meeting is a go and the demonstration by Victor Marcone is on for that evening with a Sunset Bowl. You will enjoy this demonstration because it has a little of everything in it. Bowl turning, texturing using the Sorby texturing tool, Airbrushing, beading, and applying a gilt cream. Looking forward in seeing some of the snow bird faces returning and the evening should be a fun time for all. This months newsletter is a bit short due to the storm canceled September meeting, but with the October meeting approaching, we will return to a normal page length. Glad to hear all is OK with everyone and will look forward to seeing everyone at the October 5th meeting. Turn Safe...

3 Since there was no meeting this month and no Show & Tell, I thought everyone would like to see a really nice Cosmic Platter that Dave Beathauer did in his shop up in Pennsylvania this summer. Please feel free to send pictures of your turnings for publishing in the newsletter.

4 Chips & Bits September 2017 The Benefit of a Well Made Tenon Have you ever made a tenon for a scroll chuck only to reverse your bowl and discover it doesn t turn true? If you understand what shape and dimensions are required for a tenon to fit the jaws of your chuck most securely, and then make the tenon accurately, your bowl will turn truer and reduce the time required to retrue it. Most of my experience is with dovetail jaws. They pull the jaws tight against the base of the tenon as they are tightened around the tenon, which creates the best potential for a true fit. Profile jaws clamp straight in against the tenon compressing the wood with the serrations of the jaws and are less likely to clamp with as much accuracy. The inside of dovetail jaws, the clamping part, is smaller in diameter around the base of the tenon and larger in diameter around the end of the tenon. When the tenon is properly formed, the larger diameter of the end of the tenon will not pass through the jaws, holding the work securely in the jaws of the chuck.

5 It is best, when possible, to make the tenon the appropriate diameter to fit the jaws when the chuck is scrolled in nearly all the way. Scroll chuck jaws are manufactured in a completely circular form and then cut into four separate jaws that slide toward the center of the chuck as they tighten around the tenon. Vicmarc jaws form a perfect circle when there is a 2mm gap between adjacent jaws to allow for the kerf of the saw blade that was used to cut them into four jaws. When cutting a recess in a bowl blank for the outside of dovetail jaws to expand into, make the recess just larger than the jaws when they are completely closed. When the jaws are expanded beyond a true circular form, they will still hold, but your work is more likely to turn true when the jaws make contact completely around the tenon.
