A 14” bandsaw was donated to us by the Charlotte Woodturners. It needs repairs.

Demo turning a plate with a 1 ½ inches-thick piece rectangular to make square shaped plates in Ambrosia Maple. Use a smaller gouge with an “Ellsworth” grind approaching using the “riding the bevel” technique only. If a regular scraper approach is used it becomes too rough and tears out the wood when it would not need to be. Starting between centers the bottom of the plate is profiled, and by holding a white paper behind the plate sighting lengthwise along a side will easily show an irregular profile (thickness) and the uneven ridges inevitably formed during the bevel cuts.
Set the completed bottom plate back on the lathe by reverse chucking or use the “jamb chuck” technique to turn and finish the top. Most of John’s gouges were ground with the “Ellsworth” grind and he used them for all the cuts tonight. He also used the very slight burr formed on the rear side of the tool by sharpening on a grindstone as a standard reverse scraper and he made several very fine finishing passes resulting a quite smooth surface with very little sanding.
Double and triple check the chuck tension to verify the safety of the hold. A special technique is to drill a small hole into the top center the correct depth to determine the proper depth cut and rid the bowl of the middle “peg” early in the cut. Set the tool rest at the proper height to allow the final distance to rid the center “peg” from the bowl. Remember to use only “riding the bevel to make the smoothest cuts, less tear out, cutting from the outside edge going on to the center.
If one makes a smaller center “ring or ridge”, John showed how to use a wooden jig to mark a line off-center emanating from the center circle to the outer edges. This provides a motion element to a plate especially if the lines are then cut non-uniformly giving an added sense of high speed rotation. Al Stirt, a very successful carver/turner achieves high dollars per finished piece….over $1000 for a plate! John showed the Dremel with a vibrating adapter and a v shaped bit to carve lines and other accents on the pieces.
John reminded us to always finish a piece completely with sanding since it will change slightly making it impossible to sand later except by hand. Time spent at the first opportunity is slight compared to time later.
The evening was quite engaging and valuable for additional skills to make very interesting pieces. John is an excellent and accomplished teacher and we recommend him for other demo times.
The raffle produced $45 and several cherry blanks (donated by President McKeithan) sold for the clubs benefit was $25.
Next Month: Goblets, followed by Pepper Mills (Sept), and then Christmas Ornaments!
Meeting adjourned at 9:00 pm.
