Welcome to the forum!
In case you’re interested, one of the interesting conclusions we came to earlier in this forum discussion was that “lemonwood” rarely if ever means “wood from lemon fruit trees”. These days, it seems to be used mostly to mean lemon from a variety of different other trees. The Oxford English Dictionary says:
a. A New Zealand tree, the Tarata; b. a name for several tropical American trees or their light-coloured wood, esp. the Cuban Calycophyllum candidissimum.
We’ve also seem some evidence that "lemonwood’ may have been used in the United States to mean pretty much any light hardwood tinged slightly yellow with sulfur or other treatments. For products produced here, that means mostly likely birch, which is plentiful in the northern part of the country and Canada.
My favorite takeaway from our discussion so far is that good shoe pegs can likely be made of many different kinds of hardwoods. We could potentially even use fancy woods for different colors and effects. But I personally haven’t found a way of making them myself at home that I’m excited to recommend to others.
