West Hawaii Woodturners
Minutes of December meeting 12/12/2015
President Ralf Soderberg opened the meeting promptly at 10:00 am and determined that the next meeting of the Woodturners will be February 13, 2016. Coffee, Christmas cookies and candy were up and ready for consumption.
Visitors – Dick Wagner introduced his “nephew from America” who happened to be an electronics/sound expert who fixed our faulty sound system. Thanks, Dick.
Kelly Dunn was available to collect membership dues, and a few members complied. As the treasurer, he also provided the cash balance in the Treasury. Due to security concerns the amount is not disclosed herein.
Potential Demonstrators – Kelly reported that the only demonstrator now on our schedule was Dixie Biggs for May 2017. A discussion of potential demonstrators was discussed. Dick Gerard, who is known for his work on totem poles, boats, and other unusual projects, will be in Hawaii soon, but not on a Saturday that we could set up for a demo meeting. He could however, be available for a private demonstration. Suggest that interested members contact Kelly if interested in setting up a private demo. Kelly suggested that we invite Craig Mason from the Honolulu Club to do a demonstration.
Next Challenge – Jack suggested that the members “try” to make a helical segmented piece. After the members asked what helical piece looked like, Jack passed around a helical vessel for the unknowing to examine. It was determined that Jack should be the next demonstrator of the helical process. After little discussion, it was determined that the challenge piece for the February meeting will be a platter or disc shape with no size limit.
Show and Tell – John Mydock did it again!, and presented a finished vase that is beyond adequate description due to my limited vocabulary. See the photos. The vase was a re-iteration of a prior Harley gas tank project, but this time it was a collaboration of Gregg’s masterful segmented turning and John’s ultimate expression of art and patience to produce it. The magic paint he uses is catalyzed urethane.
Richard Roberts presented a number of split logs pieces that had circular cutouts taken for turning, but he pointed out the left over firewood could actually become artwork.
Dan Gerhart presented a sample board of sanding and finishing techniques that he employs. His favored finish is water based polyurethane manufactured by the Valspar Company. He normally sands the surface up to 220 grit, applies the first coat in Gloss and then works the additional coats through a series of MicroMesh grits, all the way up to 12,000 grit with vacuuming between applications to remove the prior grit particles. Very informative.
The Christmas gift exchange – Participating members in the gift exchange brought a woodturning item for last meeting’s challenge piece. Each participant was given a number card that Kelly paired with another number. Each pair swapped their challenge gift. The following “gifts” were presented:
- Rick – Pair of sugi pine bowls approximately 5 inches in diameter
- Steve – Turned bottle stopper with Niles stainless steel stopper plus a second stopper for the recipient’s imagination.
- Al – An inside out ornament with a spiked ball insert.
- Jeff – A full circle candle holder made from curly maple & koa
- Gary – A Mango goblet
- Kelly – A “Mana Ai’I” koa bowl, which is traditionally given to the first child in the Hawaiian culture.
- Dan – A kaleidoscope made from Macadamia
- John – Three inch diameter Milo dish with front and back wood burned engraving from his “Aloha Series”
- Richard – Footed mango bowl
- Gregg – Mango vessel with ebony and burned embellishments
- Ralf – Segmented Candle holder
The winners of the gift competition were:
- Novice – Ralf Soderbergh
- Intermediate – Dan Gerhart
- Master – John Mydock
The Demonstration/Lecture – Kelly Dunn discussed his methods and tools used to prepare a turned surface for finishes, also known as “sanding”. Some of the salient points follow:
- The normal chain of grits used for bowls is 60 through 320
- Use “UHU” for remover
- Use 2” and 3” sanding discs with Velcro backs
- The best velcro sanding pads are from Australia, be sure to buy the extensions with the pads
- For aggressive work use the Power Lok system, which is available locally from Fastenal on Maiau Street in the Kaloko Industrial Park or through the many catalog sources.
- Buy velcro backed sheets of industrial sandpaper by the yard. Make cut outs with dedicated scissors and leave some square corners on the rounds as they “help” the sanding process.
- Use 5” PSA (glue) pads by Norton
- Ryobi makes tapered and round buffing pads that work very well.
- Make your own sanding devices from cork and all thread, attach sand paper with Shoe Goo. Also experiment with Adhesive Sprays – 77 for replaceable discs, 90 for more bond.
- Dremel type split mandrels hold sandpaper for “tiny” work.
- Foam for pads can be obtained from rubber slippers, kneeling pads, glass spacers, camping mats, etc.
- Learn to sand in forward and reverse rotation
- Put up and down layers of sandpaper on screw top Dremel mandrels to make a flap sander for small spaces.
- Jewelry supply outlets have numerous devices that can be used for burning & doming on wood.
- Dremel grinding stones make burned-in holes in wood.
- Learn to operate at slow rotation speed for irregular shapes
- When hollowing learn to go from out to in on side grain turnings and in to out on end grain turnings.
Miscellany: Ralf gave out lemon juice dispensers for stain remover, which also works well on the hands after cleaning fish. Steve provided 2”x 8” turning squares made from clear Canadian Spruce.
