Thanks guys.
I've often thought it would be nice to be able to actually sell stuff like this and make something at it, but unless you build them 'in multiples', it would be hard to get a reasonable price for them. In hindsight, it probably would have been a good idea to just make several at the same time as long as I had machines set up, and hope to sell them. :S
You'd be amazed at how much time you can put into something like this with setting up jigs, fixtures, stops, router bit depths, etc. (mainly the column with the flute spacing, etc.)
Pretty much a 'niche market' too.
