Hi All, Here are a few interesting pages that may give you some ideas on building a keyboard from scratch. http://www.sentex.net/~mwandel/organ/organ.html http://www.well.com/user/smalin/organproject.html http://www.angelfire.com/mn/organlcms/organpro.html http://www.archive.org/ and put shift.merriweb.com.au/harmonium/diy/index.html into their search box, then pick one of the page dates and click on the link on making a small organ keyboard. (The original pages on the 'net are gone, but the Internet Archive has them archived.) Later, Mickey
