More accurately, perhaps you mean require less imperfection than one's hand-eye skills allow one to achieve?

I have in the past made a curved jig for the thicknesser to put a shallow curve in some stool tops. You basically have to make a sled with the reverse profile on the bottom of the jig and feed it through the thicknesser taking shallow cuts and allowing a bit each end for snipe and screwing the blank to the jig. It sounds a bit dangerous but it worked suprisingly well. You will be limited to the width of your thicknesser so would have to glue up 250mm blanks after machining unless you have a wide thicknesser.

or sometimes you require perfection Well in point of fact very high levels of precision are possible with hand processes. This is the basis of all engineering, as David Pye also points out. IMHO if anything the engineering tendency tries to bring too much precision into woodwork. Perfection is not the issue! |

well from my point of view, that is an interesting idea jacob  i think with your favourite material, mdf you can be quite accurate in an almost engineering way, however, with REAL wood, it is more difficult because of the movement and grain direction. thing is if you do not have the various tools that the old guys used, ie compass planes, spokeshaves etc, it is very easy to assume you have to use a machine to get the effect, where as what you need to do is disect the item and see how you can make it more easily to allow you to use the minimum of tools and get the same effect. paul  |

The long version being: If your ten thumbed idiot, then using a jig takes out at least some of the room for error. Also, unless you've been doing it for 20yrs, getting 6-8 items exactly the same is a challenge to say the least. |
