Router plane

Large Router Plane drawing. A-A is if you cut the drawing “A” in half and turn it on end.
Use two pieces of wood..a hard wood for the sole such as service berry, white oak, hornbeam and another wood for the rest of the body eg maple, walnut etc
Glue up the pieces
Do the above drawing on graph paper carefully and Lay this out on the wood.
Drill the holes..make sure of what size cutter will be used.
Saw out the slot
Router the top profile
Sand up




  Large Router Plane



Small router plane 4 1/4 inch x 2 3/4 inches  7/8 inch diameter hole.The depth is 1 1/2 inches
Use  a hard wood for the sole to resist wear : Hornbeam, Serviceberry, Ironwood,

Drilling, Using Hack Saw, Shelf project continued

Attendance: Keenan, Shawn, Jim Hiltz, Jim MacLean, John, Miles, Paul, Rick

Leo had some firewood scraps that he turned into vases: Russian Olive, Lilac, Beech
He challenged us to identify the wood..Rick rose to the challenge

He discussed how to drill a hole down the center of a rough piece like these;

Locate the centre on each end
Make a platform for the drill press
Chuck in a straight rod
Drill a small hole in the center of the platform and move it so that the rod enters the hole
Clamp the platform in place
Place a dowel pin in that hole
This locates the center of the wood blank accurately
Drill down through the top half way and then flip the piece end to end to drill the opposite end
See photos

Leo discussed how to straighten a bent rod:
Place it in the drill press
Turn it to locate the high spot and strike it with a hammer

To cut a nut in half:

Clamp it in the vice
Use a Hack saw to start a cut and take long strokes
After a few strokes turn the nut 180 degrees and cut again
This minimizes wandering of the hack saw blade
Once done, the nut is cleaned up on the metal lathe

Tips:

Shafts are always measured in sixteenths: thus a 3 inch shaft is actually 2 15/16 diameter

Rick worked on the bowl lathe

Miles, John, Shawn, Keenan started the dovetail shelf project  using hand planes to flatten the wood
Paul and Jim Hiltz cut the threaded rod into 7 inch lengths to make the screw chuck for the large vase turnings

Vases

Keenan, Arno,Jims,Rick Miles, Paul

Rick began to work on a new bowl
Arno and John and Keenan worked on the lathe between centers-shaping coves
Jim Hiltz had a large pine log that he started to shape into a large vase
Leo helped everyone along and set up the Machining jig for Ricks bowl


Miles had  a segmented bowl project going on

The new members practiced making coves on the spindle lathe using various cutters: scraper, gouge, and skew.

Leo discussed making the heavy duty tool rest for hollowing out a vase and the older members plan to work on making this device. (Also Paul, one of the younger members, wants to make one). We need some plate metal welded into an "L" shape and a rod to mount into the tool rest holder for each persons lathe.

Leo discussed his new method of mounting a vase on the three-jaw chuck. He manufactured a sturdy screw mount from a large threaded rod that fits into the 3-jaw chuck. The jaws are reversed and then tightened into the rod which is itself screwed into the end of the blank. This creates a solid hold--better than the usual chuck mounts. He decided to help make the needed components for this mechanism.

Rick volunteered to gather up the metal supplies for this project.

The steps involve:

Getting a length of threaded rod (cadmium coated) of suitable diameter for each person's chuck
Large nuts and washers
Drilling into the wood blank
Placing the threaded rod into the drill hole which is filled with epoxy ( i.e "casting" a threaded receiving hole into the wooden blank)
Drilling an escape hole adjacent to the main hole to let the epoxy out
(Parting agent and wax are applied to the rod so that it can be unscrewed once the epoxy sets)
Making a Tap to clean out the newly formed threaded hole

For the time being he advised we can use a Lag screw or Coach screw in the 3-jaw chuck as this is also a solid way to mount the blank for a vase.
Leo turned down the square heads of a few lag screws tonight to fit the various chucks that we brought in.
The images help explain what this discussion as all about.

Rick, Arno, Shawn, Paul, Jim Hiltz, Jim MacLean, Miles

The meeting was held at Jim MacLeans.

Rick reviewed the history of the "association" and we all reflected on the past sessions.
We discussed the upcoming year and tentative projects.

We settled on doing a simple shelf  using sliding dovetails for the brackets as  a good project for all of us, and the new members especially, as this re-inforces the need for sharp tools and Straight, Flat , and Square measurements. Also such a project will never be a redundant piece as we always need a shelf somewhere. There will be great satisfaction in a hand made shelf, no matter how small. The project will incorporate finishing issues as well so will be a beautiful initiative.

We reminisced on past projects and bragged a bit

The Craft Show at Leo's that we did ,  and the Proletariat display last year at CBU  were big hits with us all.

The new members seem to have an enthusiasm for woodwork that  matches the old timers so we look forward to a good year and hope that Leo's health and our own hold up.

Shellac flakes, Gold leaf, Staining Cherry

Keenan, Arno, Jim MacNeil, Jim Hiltz, Rick, Paul, John

Leo set up an old Craftex lathe that Miles had sent over and started to explain to the new members the principals of lathe work.

Arno wants to have Leo take them through the bowl process starting from scratch--ie the raw wood blank from the tree.

Paul worked on the Gold leaf vase. Jim Macneil helped out with that.

Jim Hiltz brought in a finished bowl, ready for staining and finishing.

Leo discussed finishing Cherry.
It is very hard to stain as the end grain absorbs too much stain. Best approach is;

Finish sand to 800-1000 or higher
Spray on Shellac.  Shellac is food safe. It is a biological product gathered from a certain tree species. Insects produce the shellac.
Let that dry
Wipe on the stain . Mix the stain first with household ammonia. This makes the stain adhere; otherwise it would not .

Then let that dry and repeat the cycle a few times. This results in even staining. The more coats the darker the cherry will become.

Shellac is best made using flakes; blond or super blond best. (Available from Wood Essence-Canada)
Use one measure of flakes to 4 measures of Methanol.

Keep flakes in a dry place as they absorb moisture and get spoiled .

We discussed having a separate meeting with the new members over the Holidays to discuss plans for the upcoming workshops.

NOTE

Leo discussed Shellac. He is studying modifications on the use of the age old finish.
Shellac comes from the secretions of insects;

Lac is the scarlet resinous secretion of a number of species of lac insects, of which the most commonly cultivated species is Kerria lacca.
Cultivation begins when a farmer gets a stick (broodlac) that contains eggs ready to hatch and ties it to the tree to be infested.[1] Thousands of lac insects colonize the branches of the host trees and secrete the resinous pigment. The coated branches of the host trees are cut and harvested as sticklac.
The harvested sticklac is crushed and sieved to remove impurities. The sieved material is then repeatedly washed to remove insect parts and other soluble material. The resulting product is known as seedlac. The prefix seed refers to its pellet shape. Seedlac which still contains 3-5% impurities is processed into shellac by heat treatment or solvent extraction.
The leading producer of Lac is Jharkhand, followed by the ChhattisgarhWest Bengal, and Maharashtra states of India. Lac production is also found in BangladeshMyanmarThailandLaosVietnam, parts of China, and Mexico.

Shellac flakes can be dissolved in Methyl alcohol
They come in various colors: Orange, white, blond, and ultra blond: 
(Available at Wood Essence in Ontario) The flakes will deteriorate unless humidity is low.
Orange is the hardest to use as it colors up the grain too much
Use a ratio of:   1Flakes : 4 Methyl alcohol
This solution should be stable for a good while
This dilution is OK for spraying  use a low pressure or it will gum up on the surface of your wood.
Jig for getting into the bowl to turn
Note the plate on lathe bed, the wood rest on which the metal arm sits

The L-shaped rest is sturdy  3/8 to 1/2 inch metal plate
