Members MargeHowel Posted September 8, 2011 Members Share Posted September 8, 2011 someone gave me one that's not "Regulated" (tuning the action)but it looks to be in sound shape it's a simple on a "z-box", apparently they made kits in the 70s or so Link to comment Share on other sites More sharing options...
Members suitandtieguy Posted September 8, 2011 Members Share Posted September 8, 2011 who made it? what do the jacks look like? are the jacks wooden or plastic? Link to comment Share on other sites More sharing options...
Members MargeHowel Posted September 8, 2011 Author Members Share Posted September 8, 2011 Z-box's are made by zuckerman -- but they sold kits, so who actually MADE it is up in the air the jacks are pearwood I believe (that's pretty traditional, right? could be another wood, I'm not very good with wood species) but the plectra look to be a synthetic material Link to comment Share on other sites More sharing options...
Members mate_stubb Posted September 8, 2011 Members Share Posted September 8, 2011 The action is so simple, I don't know what adjustments are available or needed. Tuning is a different matter. In either case, it should be way simpler than working on a piano. Link to comment Share on other sites More sharing options...
Members MargeHowel Posted September 9, 2011 Author Members Share Posted September 9, 2011 The action is so simple, I don't know what adjustments are available or needed.[/quote there are adjustments on the jack -- there's what looks to be jack height screws and the plectra are on that pivot mechanism that has what looks basically like a "preload" on the return . Then I suppose there's the plectrum position and shaping and that sort of thing. seems like a black art to me though Link to comment Share on other sites More sharing options...
Members suitandtieguy Posted September 9, 2011 Members Share Posted September 9, 2011 the screw on the jack is the only point of regulation on my harpsichord, which is a Baldwin solid-body electric harpsichord. my jacks are plastic and eventually i'd like to re-jack and re-string this thing. the good news is that you can experiment a lot because your jacks are cheaper to replace than mine!

Members MargeHowel Posted September 9, 2011 Author Members Share Posted September 9, 2011 On the down side of the wood is that the whole show changes with the temperature and humidity and such. A person told me a common trick is to burnish the jacks with graphite powder into them to help the 'sticktion', but I haven't tried it. The action is simple, but it seems like that puts a lot of the burden on getting the simple parts set up jusssssssttt right (it doesn't compensate for itself)...I'm not looking forward to shaping and setting the plectra, though it looks like the "preload" adjustment on the pivot could help fine tune that any advice on getting those in the sweet spot?
