Quick and dirty bowl finish


 
For my beginning wood turning class, I just completed my first bowl. It had a few dings, and is made of plain poplar, so looks unremarkable. This is compounded by the limited amount of time I had in which to sand the bowl on the lathe. I was able to get it slightly sanded, but not thoroughly.
 
This left me with a dilemma. I could either hand sand it to a very fine grit, and get it to shine, or I could do something quick and dirty.
 
Being as I was planning to use this bowl to hold various bathroom toiletries, (as it’s too crude for a gift or for display, but is the right size and reasonably stable) and poplar is semi-soft, a labor intensive high polish would be scuffed in no time. So I went for something quick and dirty.
 
Step 1. I sanded it down to 200 grit. It still has some marks and dings, but feels smooth. A particularly prominent ding had a leaf carved over it.

Step 2. About twenty-four hours apart, I applied two generous coats of walnut oil. A denser wood may have needed to be wiped down after application, but the poplar was porous and swiftly absorbed most excess oil. Walnut oil is great stuff. It’s non toxic (which makes it great for kitchen utensils and toys), brings out the woods natural color without yellowing it unduly as Danish oil might, and it’s ridiculously easy to apply. As with any oil, oil soaked rags, paper towels etc have to be dealt with cautiously, and anyone sensitized to Walnut sawdust may wish to research its safety specific to them, but it’s really great stuff.

Step 3. There is no step three. Any repairs or maintenance on the bowl can be easily accomplished by sanding or adding more oil. I wouldn’t quite say that it glows, but it looks warm and does its job.

The Left Handed Myth

I stumbled on an old myth that annoys me, so brought this blog out of storage to rant a little.

Studies have been done which show that the number of left handers drops severely with age. This is presumed to indicate that left handers have a notably shorter lifespan than right handers.

This is an interesting theory, except that it is incorrect. Back in the olden days, lefty schoolchildren were forced to switch to being righties. Senior lefties who were subject to this, learned to write with their right hand, and thus closeted, would be counted as righties. After school policies became more civilized, younger lefties were never forced to switch, and would be counted as lefties. Because senior lefties appeared to be righties, the number of young lefties to old lefties would seem to drop severely.

Thankfully this drop is caused by the statistical error described above, not the grave.

Two final thoughts, there's a hilarious Dave Barry article that made me nearly hurt myself laughing here, http://articles.chicagotribune.com/1991-07-14/features/9103190719_1_right-handed-people-lefties-desks and second, I've noticed that a surprising percentage of contractors are left handed. I don't know quite what to make of that, but find it interesting.
