Barrels, casks, and other containers

http://www.math.nmsu.edu/~breakingaway/Lessons/barrels_casks_and_flasks/Barrels_Casks.html

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

Minutes March 24/09

Attendance: Joe, Paul, Chris, Wilson, Naq, Miles, Robert, Roy

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.

Chris Caldwell

Chris Caldwell is another gentle giant...there are a disproportunate number of them in the club !

Chris is a Golden Clubber..member since the start.

He is a millwright.

He never misses a meeting.

He is a prince of a man.

His retreat is MacKinnons Harbor..you have to see it to believe it.

Meeting March 3, 2009

The meeting tonight was a business meeting, held in the school on Hornes Road. Thanks to Rick for arranging this with the school.

Attendance: Miles, Murphy, Leo, Rick, Lawrence, Jimmy MacLean, Jim Hiltz, Chris Caldwell, Roy Troke

Jim Hitz presented a letter that has been received from the Nova Scotia School of Crafts. We have been invited to host a display of crafts in the Lyceum on George Street in 2010. The display would be hosted for one month. It was proposed that each member have a few pieces to display. Another idea was to have a display on the evolution of a large bowl, starting from choosing the tree and working to the end creation. A slide show or video are other options. A display of curious tools was also suggested.

The membership agreed that we are interested and Jim will contact the School and submit our agreement. We agreed on the $25.00 submission fee.
Serious work has to be done toward this project.

Lawrence noted that we have a substantial bank balance and all dues are up to date.

The next item was a presentation of the new web page by Paul who stumbled through this haphazardly.

People seemed to think that this is a worthwhile thing and that we should endorse it. Each member had an opportunity to play around with a computer terminal to see how to navigate through the site.

Paul demonstrated the elements of the page, how to navigate through it, and also went through (rather quickly) the development side of the page. The good thing is that the whole thing is absolutley free. The template that is presently being used is good because it it easy to read (ie the color scheme), and if you click on the right hand bottom corner of your screen page , you can drag the page to the widest view that your screen allows and the page elements will expand to fit this.

This has great potential, including the possibility of making a few dollars if we permit advertising.
It also has the potential of allowing those of us who make a living out of our hobby to advertise their work.

We need ideas on what elements to include on the site, such as:

links, posting items, gadgets, tools etc.

Please let Rick or Paul know by email what you would like.

For the time being the administration of this site was left to Paul in order to avoid confusion and haphazard altering of the main elements of the web page.

Send Paul pictures by email that you would like posted.

Also let Paul know if you want your "bio" changed. The present information is just a test start. Ideally it would be nice to have a short bio on each of us with some interesting background information..stuff that you don't mind being on the world wide web.

Next meeting is this upcoming Tuesday, March 10/09.

Miles MacDonald

Miles MacDonald is one of the newcomers to the club. he joined in the latter part of 2008 and is showing great enthusiasm so far. Miles' work is intricate as you can see.
