Left hand shooting plane.

[Tom Stenzel]

Hi Stewie,

That is some beautiful work. Nice little touches down to the chamfer on the front of the brass runners. Does the "knurling" on the right handed plane help with grip or is it decorative? You mentioned the wood is oily.

I know when I've tried pinning metal I can always see the pins. Looking at yours I don't see ANY evidence of the pins. Please tell me that the pins are in blind holes and don't go through. I won't feel so inadequate.

Nice Plane Stewie.

I am somewhat ambidextrous, equally bad with both hands.

Hi Jim,

I've long said that I was antidexterous as I'm equally incapable of doing anything with either hand. If you want to use the term too feel free. I won't sue. Besides, I'm too cheap to hire a lawyer.

If you want to feel really inadequate about pin visibility then you should read Konrad Sauer's blog for a while.

If you want to feel really inadequate ...

Too late Patrick. George Wilson took care of that long ago!

Hi Tom; the turned surface helps maintain contact between the webbing of the controlling hands forefinger and thumb. The brass pins are secured within the timber. Appreciate being told they are difficult to identify.

Wow, that's some seriously old-school thinking.

Back in the day we (society) decided that lefties were willfully rebelling, and forced them to "repent and retrain" on more or less that basis, sometimes using fairly draconian methods. With the advent of FMRI it's become pretty well established that left-handedness is correlated to real differences in brain laterality, so the theory that you can make yourself anything you want is questionable.

Really? That's not quite the approach I was advocating.

I've done some preliminary research on this, but I have not found any studies attempting to rule out the possibility that it's a self-reinforcing phenomenon / self-fulfilling prophecy. I do know that the prevailing theories currently are that there is some genetic basis, but I've not seen developmental causes specifically controlled for. We know that the brain is incredibly plastic and changes depending on how we use it. After a lifetime of favoring one hand over the other, even if that hand were arbitrarily chosen, do you not suppose one's brain would develop differently than if the other hand had been, again, arbitrarily chosen? I'm not arguing that there aren't observable differences, but that the development of those differences may be dependent on our actions and preferential development.

But, I digress. That's merely my intuition, and I've not come across any studies or information examining that distinction in a way that sufficiently controls for developmental factors. It seems it would be a somewhat difficult thing to study, given the kind of length of time and development that would be required.

Anyway, I don't mean to take the thread off-topic. I am genuinely interested in this topic and curious if you know of any studies that you think address my concern, though. I do acknowledge that I'm not as knowledgeable as I could be on the topic, so I'm definitely open to new information.

In any case, I still stand by my opinion that most people can easily develop skills in either hand if they so choose, but tend to choose not to due to preconceptions of hand-dominance. This is anecdotal and separate from my postulations on the underlying causes of hand dominance, though. In some instances, this is not necessarily a bad thing; it requires almost double the time and effort to develop both hands equally, and so often is not an efficient use of one's time. But there are many instances where it is highly beneficial to have use of either hand, and people would do well to take a more flexible approach to their perceptions of what they can and can't develop.

Well, it's questionable Pat, but I think Luke's telling us (as well as George) that he did it.

Some people have less lateralization than others. The fact that they can do it doesn't mean that everybody can. That was my main point, and yes, I realize that this is a slightly circular argument inasmuch as lateralization might change due to plasticity.

For the most part lefties tend to me much more ambidextrous than righties (left handed children tend to present as ambidextrous at first, as both of mine did), and also tend to have less brain lateralization in FMRIs. George is a lefty, and he's from an era when we tried to retrain them all into righties, so he may have both a predisposition to ambidexterity and possibly a lot of practice very early on.

The reason I'm kind of strident about this is because we did a LOT of damage to several generations of lefties (even if the stuttering thing was likely bogus) based on a non-evidence-based belief that they chose to be the way they were.

Luke, you aren't originally a lefty are you?

Hmm... I honestly don't know. I'm kind of ambidextrous, but for most things that are designed for right-handers (ie, writing, computer mice, etc.), I use my right hand. As a result, I do tend to develop my right hand more, and so I'd say that I'm probably right handed.

According to my parents, I had no clear preference for right or left as a child, so there is a possibility that I may have been left-handed originally I suppose.

I did do an experiment for a number of years, in which without changing my other behaviors, I always used chop-sticks in my left-hand. I did this for so long that using them in my right hand was awkward, and it was easier to use my left. I've long since changed back to my right hand, and now the reverse is true.

I do agree with you that, in any case, that there's no justification for trying to make children conform to right or left-handed preferences, and that it can be potentially harmful to do so. I think that to be true regardless of whether hand dominance is a genetic or learned preference, or some combination of the two.

I think people are wired different. Some can use both hands for various tasks. Others have difficulty. From what I have read the control of the right side versus the left side are controlled by different sides of the brain. There is one theory about engineers having the highest percentage of left handed members among their ranks of all the professions.

My left hand writing isn't as legible as my right hand writing. Of course our writing system is designed for right handed writers.

Brian; Its a crazy world of complexities.

Finished building my new shooting board. Works a treat on both left and right hand shooting planes.

[Derek Cohen]

Stewie, if you are using MDF for the platform, I would recommend that you edge the platform in hardwood. The hardwood will prevent the soft MDF absorbing moisture, and it will prevent it spelching.

Below is a doudle-sided shooting board, one of several I built 5 years ago for the public to use at a LN Tool Show at which I was demonstrating. Note that the platform is edged with Jarrah. The runways are not edged, but they were sealed, as was the entire MDF surface.

The design was borrowed from the LN website (appropriately). There is also a removable mitre fence.




The fence has non-slip added. This is a fine powder sprinkled over a layer of poly varnish). The non-slip is necessary for shooting mitres.



If you look carefully, you will note that there is a dust groove on each side of the platform. You should add this to yours. It avoids dust buiding up, which would affect the accuracy of the plane-runway interaction. I add these on all boards.

Derek; 3 coats of Feast Watson Proofseal has been applied to the mdf edges and top surface as an effective sealing agent.
