Producing handles or knobs for any tool is a tricky thing.  Everyone’s hand is a little different as are their preferences as to what “feels” right.  It’s not surprising then that with the six router planes we studied the shape, diameter, and height of the knobs were all different.  Stanley, for instance, had the shortest and fattest knob while Millers Falls had the tallest and second narrowest.  Lie-Nielsen’s knob fell right in the middle of height and diameter and I would say theirs is the most balanced of them all.  Veritas, on the other hand, was the most unique with handles that tilt roughly 30 deg off vertical and were some of the tallest in the group.

The Preston 2500P knobs were unusual due to the fact that they are designed to be quickly unscrewed and moved to different positions on the tool (more on that in a later post).  The knob itself is not very tall, but its height ends up right in the middle of the other planes because of how the body is designed.  The diameter, however, is by far the smallest of the six measuring only slightly larger than 1.5″ where as the others average about 1.7″.  That may not sound like a lot, but you can feel the difference as soon as you put the tool to work.  This left us with a decision to make; remain as faithful to the original as possible or deliver what we think is the best all-around knob we can.  Ultimately we decided to leave it up to our customers.  We’re going to offer knobs that are replicas of the original as well as knobs based off the Stanley which are a little over 1.75″ in diameter and have a mushroom style profile.  The Stanley was our personal favorite among the all the profiles we tested so we wanted to make them available, but offering the Preston style has historical significance and will undoubtedly be preferred by some portion of the woodworkers out there.  We will also be happy to sell either style knob to those of you who may own an original Preston plane with knobs that need to be replaced.

So that’s the story behind the knobs.  We haven’t finalized our material yet (feel free to comment on cherry vs. walnut), but we will be offering two styles which hopefully counts for something.  Next time we’ll discuss a few changes we’ve made to the original design and how that benefits the user.
