May 10 2017 Malcolm Zander demo

Notes of KWT Club Meeting of May 10, 2017 held at Frontenac High School.

·         Nelson called the meeting to order at 1855.


·         Herb discussed the Joint KWT-KWA symposium to be held at the Communications Museum of June 10.

o   Objectives of the Gallery is to show the public the work KWA and KWT members do and to raise the profile of our respective clubs

o   Show to be called “Artistry in Wood 2017”

o   Registration for the event is free to KWT members but the organizers need to know you’re coming. Therefore, there will be a registration. Registration forms were available at the meeting. The registration form will also be posted on the KWT Website.

o   A brief description of items should be included with the registration. The “item size” part of the form is not really applicable to KWT. It is geared toward KWA, some of whom could be bringing in large furniture items.

o   Entry of items will be open to KWT and KWA members (only) and items will not be screened / juried.

o   Members were strongly encouraged to submit at least one item. Organizers are looking for a broad spectrum of work from turners of all experience levels.

o   If you are unable to attend, please leave a piece or 2 with someone to take on your behalf

o   Tables are 6 ft in length.

o   The room is available for set-up from 1300 – 1600 on Friday

o   Small posters are available. Please take 1 or 2 to post in local businesses

o   There will not be an entry fee to members to display / sell items or a club commission on sold items.

o   Sale of items will strictly between exhibitor and buyer

o   In order to encourage attendance, entry will be free to the public

o   Exhibitors must bring their own extension cords if they need them


·         Malcom Zander from the Ottawa Valley Woodturners made a presentation and demo of turning thin walled pierced vases. See also Malcolm’s handout (available on KWT website at

o   No sophisticated tools are required.

o   A 60o bowl gouge is used for 95% of the time, with a 45o bowl gouge also used

o   Endgrain and cross-grain examples were presented

o   Why thin-walled?

§  Create a form with lightness and delicacy

§  If the item is pierced, a thicker wall “closes off” the holes when viewed from obligue angles.

o   Why use dry wood?

§  Dry wood moves much less during turning

§  Gives more time to the turner to cut the thin wall without the piece becoming oval during turning

§  The piece can be sanded to its final finish on the lathe

o   Why use cross-grain blanks?

§  No special tools are required, just bowl gouges

o   Malcolm’s current work evolved from starting with natural edge bowls with sapwood rims

o   Most lace is based on a hexagon shape

o   The “Heart” bowls are turned end grain

o   One idea can lead to a whole series. For example, the natural edge with leaf motif

o   For a natural edge piece, the high wings must be the same height. It is aesthetically ok if the low wings (ie front and back of bowl) are of different heights.

o   Use the tailstock for support for as long as possible

o   The cone center can be effectively used during hollowing

o   Once the wall thickness is about ⅜” thick, switch to the longer bevel (45o) bowl gouge

o   To create an even, thin wall sight along the profile using both eyes.

o   Calipers can also be used. Set the calipers so there is a gap at the desired thickness. As you progress down the bowl if the gap lessens, the wall is too thick.

o   When entering a cut near the edge, use your left thumb as a steady/fulcrum to prevent the gouge from “skating”  toward the rim

o   Work in 1” increments so that the piece does not become prone to flexing during turning

o   Once you are done a section, you can’t go back.

o   When hollowing, set the tool rest to be parallel to the profile.

o   The bowl in the presentation was approximately 12” diameter with 1 mm wall thickness and sanded to 2000.

o   Piercing can be done with a dental drill or an NSK unit.

o   Both turn at approximately 400 000 rpm.

o   The NSK is a “pen” configuration, while the dentist’s drill is a right-angle configuration

o   The NSK has enough torque to handle a wall thickness of ⅛”.

o   A dental drill can go up to about 1.5 mm (1/16”)

o   A 40 000 rpm unit, such as Foredom, tends to track the grain

o   Cut with the bit perpendicular to the surface of the piece

o   Use one finger as a fulcrum for steadiness.

o   File the holes with a diamond file to smooth them and to get rid of burn marks.

o   Prior to filing, most of the burn marks can be removed by “wiping” the cut surface with the edge of the NGK (or dentist’s drill).

o   The Rollie Munro “Holy Rollie” hollowing tool was demonstrated and discussed.

o   Good light is essential for thin walled vessels and for piercing


·         Several items were presented at Challenge / Show and Tell including:

o   Box incorporating alumilite resin

Malcom has provided us with a PDF hand out from the demo he did for us .

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.
