Mr. James Hiltz, Miles, Rick, and Paul had completed some work on the project.....the body was glued up and the top/bottom pieces were done and ready to be profiled.

Leo demonstrated how to turn the outside of the urn body on the metal lathe.
He then set up the wood lathe and turned the inside of the body (of Paul’s) using the steady rest we made previously this year and his rigid heavy cutter fed into the interior of the piece by a handscrew apparatus.

Very productive workshop tonight.

April 7/09

Attendance:Paul, Rick, Miles, Joe, Chris, Jimmy MacNeil, Robert

Leo reviewed the formula for rough estimate of volume of a cask:
It is D*H/20, which give a close estimate of the volume in gallons
D is diameter, H is height
Paul brought in a Stanley #50 combination plane and Leo demonstrated how to sharpen the beading blade and how to make a wooden fence to make it more versatile.
We then discussed the Urn project.
Once the staves are glued up, we start on shaping the top and bottom.
The solid piece is mounted on the lathe between centers and rounded.
Then a foot is cut on each end:
The piece will be sectioned into two parts, one for the top and one for the bottom.

Learning point: A cylinder , once rounded on the lathe, can be smoothed using a hand plane on an angle with the lathe running.

Leo then demonstrated several of his home built contraptions for deep vase turning using heavy steel tubes and rods. Most ingenious.

Ranald Ross (Margaree) is coming into Sydney this week with some wood for me. He can take some wood in if anyone wants to see his products. Let me know what to ask him for.

Coxheath Trail-Sample photos

Here's a few photos of the trip up the trail, done on Sunday April 5/09.
It is very pretty and worth a few hours of exercise.
I think we should go up now, and again when the trees start to bud to get some close up shots of the process, and then again when the leaves are on and again in the fall.
One or two photos are out of focus...I was distracted by the young lass that I met on the way.
I took a movie of her but she bound me not to show it.
Too bad for you lads!

Not many trees have IDs but I can get someone from lands and Forrests to give a guided tour.
Shall I do that??
No charges for that as far as I know.

There is a trail in Coxheath near the Blacketts lake turn.

It goes up the mountain. People can park in the church parking lot.

The Coxheath Wilderness Association has scouted this out and marked trees with ID.

Anyone interested in scoutting it out with me to see if the club might want to do it?

Barrels, casks, and other containers

I would say that this is what Leo was referring to.

Take the average of the diameters of the barrel that you know and then , Volume =Pi*(average R)squared x height
If one does this in inches the result is in cubic inches so convert this to gallons
f you did it in feet the conversion is different.......cubic feet to gallons




So if a barrel had a diameter of 3 feet in the middle and 2 feet on top
that average is 3+2 divided by 2 which is 2.5 so use this diameter to get the rough estimate of volume

Leo discussed drill bit sizes and types. Twist bits come in inch sizes eg. 1/32,
1/16, 1/8 etc
Sizes in between this are given numericals from 1 to 80
1 is about 7/32
Sizes in between this are measured in Letters from A to d
Leo went over the method of sharpening various bits.
The Drill Doctor is a gadget that can be used to sharpen twist drill bits.

Measuring the volume of a barrel:

The barrel sides are formed by the arcs of a complete circle on each side.
Magenta line is the height H
Green is the barrel diameter (the radius of the circle that forms it )
Formula( H x D)/2 = gives volume in quarts
Divide by 4 to get volume in gallons


Next we continued on the Urn project.
11.25• angles x 4 is 45 degrees

45•

When making the strips for the body of the urn, use this trick. Cut one extra strip and use it to play with the angle .
The angle subtended by glueing two short pieces of the strips of wood together should make a 45 degree angle. Use this trick to make fine adjustments in the stave belly strips that you cut : i.e change the angle of the saw blade until you can make a 45 degree by gluing the two together.
Then cut all the strips on the saw and glue them up as was demonstrated at the last class. Plane the sides in the sled we made.
Leo helped fix Paul’s project pieces so that they glued together correctly.
Leo demonstrated how to make your thickness planer be a jointer:
Make a platform that is 12 inches wide (if you have a 12 inch planer. The best way to do that is use a core box technique of gluing it up so that it will stay flat over time and not warp.
This platform is used to lay the workpiece board on. Use shims to steady the workpiece. Tape the shims in place. Once it is fairly solidly arranged, run it through the thicknesser and you will have jointed the top face of your board.

Styrated sand paper is best for sanding finishes like laquer.

I have contacted Clarence Barrett, a forester with Parks Canada (Ingonish National Park) to do a walk through the forrest to learn about tree identification. Presently there is a ton of snow in the woods so this would not be until at least a months time.

If it goes ahead, I would appreciate suggestions about how we might reward Clarence for his time.
