Bandsaw Cut

One of the most used tools for some woodturners is the band saw. In fact, I would recommend the band saw over the table saw for most turners while for cabinet enthusiasts the table saw is the first choice. However, while I consider the band saw to be one of the safest saws in the shop, safety is still an issue.

In particular there is the cut through a cylinder, not an infrequent need for many projects. Cylinders roll. If a cylinder rolls while being cut on a band saw, chances are excellent that the blade will get crimped and either draw a hand into the blade, snap the blade, weaken it to where it will snap the next time it is used or so damage it that it will come off the wheel. Of course any combination of the above is also possible.

At best, a piece of wood is damaged and at worst a serious cut is obtained with blood everywhere. Incidentally, if a catch happens it is extremely fast and a band saw for turning usually has at least a 1/2 and likely a 3/4 horse motor. There are very few people in the world strong enough to hand the wood and prevent an accident. Safety first.

Lately I had to cut off a section from a cylinder that had two diameters. For safety reasons I wanted a level cylinder. All that took was a shim under the smaller diameter. To keep the wood from rotating I simply took a clamp that rode on the table and used its holding power to grip the cylinder far more strongly than I could by hand. The arm of the clamp prevents rotation and what might have been a catch simply becomes a cut. Take your time through the cut if the wood is green especially.

Another Use for Bottom Jaws

Woodturners have variations on how to turn the bottom of bowls. Most use a donut jig or some sort of chuck jaws such as ones with plans on my web site, Bottom Jaws. However, any of these methods can also answers what has been a problem for many of us, how to save a bowl that has become a funnel.

By this I mean the times that I have had a bowl almost finished to find that a lapse in attention has caused me to turn through the bottom into the waste block I commonly use. I know; using a depth gauge would have prevented the difficulty but so would hove not permitting my mind to wander. However, I do know that I am not alone here, most of us have some pretty kindling with nice bowl sides and a hole in the bottom.

One way to solve the problem is to glue on a separate piece of wood to the bottom of the bowl and turn it cleanly. The difficulty is remounting to the lathe so as to leave everything centered. The answer is a flip.

1) glue the new bottom in place and about 1/4" too thick.
2) mount the bowl in the bottom jaws
3) turn a tenon on the bottom
4) FLIP the bowl over so as to hold the tenon in regular chuck jaws
5) turn the inside, sand and finish
6) FLIP the bowl into the bottom jaws
7) remove the tenon
8) turn and finish the bottom

hope it helps

Simple Tool Rack

I had a question lately about making a tool rack for woodturning tools. Generally I have seen three variations on the theme.
1) a series of tubes on end to take the tool shafts. The tubes may be in a bucket or box.
2) a box similar to a shallow drawer, sometimes literally a shallow drawer with dividers to keep the tools from rolling into one another and ruining the edges
3) a board with holes drilled into it to accept the tool shafts. The board is usually fastened to a wall or near the lathe.

I like the latter concept as it is quick to make and convenient to use. However, even easier is to pick up one of those tool holders at the discount bin of the hardware store. They seemed designed to hold all sorts of screw drivers and wrenches or the life but the holes seem to fit things life standard lathe tools, knock out bars, tommy bars for chucks, lathe wrenches and the like.

Poppy Hint

Here in Canada Remembrance Day is just around the corner, November 11, and poppies are being presented for donation reception by our Legionnaires. Lots of other
countries celebrate the same day under different names like Armistice Day or even Poppy Day. When I was serving as Legion Padre in Perth-Andover, New Brunswick, we would gather at the cenotaph in Perth for 11:00, move to the the cenotaph in neighboring Aroostook Village to conduct their cenotaph service, and then go to Fort Fairfield, Maine to assist the VFW in their service as they did not have a padre. Besides, some of our memberes had served in the American forces.

As a pastor, nephew of veterans, former Legion padre, and part time services padre, I encourage everyone who can to donate to the work of the Legion and VFW and to wear the poppy to commemorate the day and be thankful for the peace we enjoy. Take time during the day to pray for our vets and for the new ones being created in so many parts of the world. Of course I am thinking today of Afghanistan and Iraq in particular, but our men and women are fighting in many parts of the world and still lay down their lives for God, family and country.

Here is hint for the poppy wearers. I am one of those people who can lose a poppy just by thinking about it, or not. So, if you are one of those woodturners who makes ear rings and has a stash of ring backs, put one over the pin of your poppy so it does not fall off. Other wise go to the cheapie display of jewelry at the discount store and pay a buck or two for some gaudy junk you would not be caught dead wearing or knowing that giving it to your wife may be an act of suicide. After all, why toss the good stuff? Dump the ear rings and keep the backs for poppies. Now you can afford to give extra for the poppy because you know you only need one and fewer will be wasted. Better for the environment and everyone else.



By the way, for extra brownie points get a really nice pair of earrings, hide them until after Remembrance Day, use the backs for the poppies, get the extra back from your wife and then give her the earrings. That of course is for the fellas. Ladies can find their brownie points on their own.


In Flanders Fields
by John McCrae
Written in Flanders on May 3, 1915

In Flanders fields the poppies blow
Between the crosses, row on row,
That mark our place; and in the sky
The larks, still bravely singing, fly
Scarce heard amid the guns below.

We are the Dead. Short days ago
We lived, felt dawn, saw sunset glow,
Loved, and were loved, and now we lie
In Flanders fields.

Take up our quarrel with the foe:
To you from failing hands we throw
The torch; be yours to hold it high.
If ye break faith with us who die
We shall not sleep, though poppies grow
In Flanders fields.
