Febuary 8 2017

Notes of KWT Club Meeting of February 8, 2017 held at Frontenac High School.
· Nelson called the meeting to order at 1900.
 
· Les Clarke provided a reminder about the KWA Symposium to be held at Frontenac High School on April 8, 2017.  The early bird rate of $45.00 ends on February 28, 2017. Thereafter, the cost is $65.00. Payment can be made online. The Symposium will have 9 sponsors (5 in attendance), a gallery, and will feature presentations by 6 craftsmen. Lunch is included.  Les also noted that the KWA Gallery is being targeted for June or July, and asked any KWT member interested in participating on the committee to speak with him or Marty.
 
· Nelson reminded the members that sandpaper, CA glue, and End Sealer were available for purchase from the club. Lathes are also available for sign out from the club.
 
· Members were informed of the benefits of AAW membership. Promotional material was provided. AAW membership includes subscription to American Woodturner (published 6 times per year), FUNdamentals (on-line magazine published 6 times per year) and other publications.
 
· The Totally Turning Symposium will be held in Saratoga Springs, N.Y. on April 1-2, 2017. Demonstrators include David Ellsworth, Curt Theobald, Jimmy Clewes, Kurt Hertzog, Trent Bosch, Lionel Bedard and others. Some KWT members will be going so there will be car pools. If interested, talk to Nelson, Dave or Joe.
 
· The KWT library is always looking for new items. If you have a book, DVD, or magazines that you no  longer need, consider donating them. It was suggested that the library inventory list be posted on the website.
 
· Trevor and Ian from the Quinte Woodturners Guild attended the meeting. Trevor provided a demonstration regarding casting of alumilite (ie resin) with wood (eg burls, pinecones) to produce blanks. Trevor’s castings can be used for game calls, wine stoppers and many other small items.  Resin can also be incorporated into bowl turnings
 
o A pressure pot is required. Cost is about $100.00 including fittings.
o Incorporating resin can make a holey piece of firewood into a very attractive blank.
o Resin is available from Woodchuckers and Leading Edge Hobbies.
o Although the resin is pricey, wine stoppers incorporating resin typically sell for $40 and Duck Calls $80 to $100.
o Molds are required and can be made from hardboard. Mold pieces are glued with medium CA glue.
o Since substantial heat will be generated, the mold material must be robust (no plastic yogurt containers)
o Molds are single use and are cut off when the casting has cured.
o After the mold is made, it is necessary to seal all the joints with CA glue as well.
o A shop built tray is used within the pressure pot to hold 2 levels of molds.
o Since wood will float, the wood is glue to the mold. Toothpicks can be glued to the bottom of the mold so the wood will sit on top and the resin will also cover the bottom face of the wood.
o Only bone dry wood should be used.
o Trevor dries his pieces in an old toaster oven set at 180o to 200o. The cycle is 2 hours on and ½ hour off.
o If not being used right away, the wood must be sealed immediately afterward so that the blank does not reabsorb moisture prior to use.
o Any soft material (eg bark) has to be removed from the wood using a pick, wire brush, or similar tool.
o Since the resin flow by gravity, the orientation of the blank (ie orientation of the cavities) within the mold is important.
o Wax and end sealer is the enemy of resin. Resin will not bond to a waxed surface
o For finishing, Trevor uses spray lacquer.
o Pieces are wet sanded to 400 to 600 grit.
o Several options for coloring are available, including:
§ Dyes (translucent)
§ Fluorescent dyes (opaque)
§ Mica Powder (sold for use in making home cosmetics. Mica powder does not absorb into the wood)
§ Oil base paints (though these are opaque and will also result in the resin not fully hardening)
o Once the wood is added to the mold, screen fabric is glued to the top edge of the mold so the wood does not float away.
o The alumilite is mixed and poured through the screen. A smallhole can be placed in the screen to allow the alumilite to get through faster.
o The aluminlite is mixed by weight, not volume.
o The open time is approximately 15 minutes. It is not necessary to hurry, but it is important to be well organized and have all materials etc ready to go.
o The alumilite was mixed in plastic cups. A mixing attachment on a cordless drill was used to ensure the product was well mixed, which is critical.
o A red dye and silver mica pigment were selected for use in the demo. The resin mixture was divided into 2 cups, with Mica added to one and the dye to the other.
o There are no hard rules as to how much dye to used Beginners tend to use too much, resulting in a more opaque finished blank. Use of less dye will result in a more translucent look.
o Once poured, the castings were placed on the tray and put into the pressure pot.
o The pressure pot Trevor uses is rated at 65 psi. There is no reason to go above this.
o Although curing time is typically listed at 2 hours, it is better to leave the blanks under pressure overnight.
o Blanks can be turned 48 hours after removal from the pressure pot.
 
· KWT offers our sincere thanks to Trevor and Ian for a very informative and interesting demonstration.
 
· The challenge for February was to bring in a tool sharpened using the techniques presented at the last meeting. Items brought forward included:
o Home-made parting tool
o Parabolic bowl gouge
 
· The following items were brought forward for Show and Tell:
o Christmas bell ornaments
o Potpourri bowl (red cedar finished with butcher’s block finish)
o A hollow shallow form
o Winged bowl (spalted maple)
o Vase (red cedar, finished with tung oil)
o Bowl (cherry)
o Bowl (burl)
o Surveying tray with integral bowl
o Hollow form (maple burl)
o Pens (Maple, Japanese Olive, Walnut and Redheart)
 
· The next Club Meeting will be Wednesday, March  8, 2017 at Frontenac High School.  The challenge will be to turn an item made from a medium other than wood.
