From this position I was able to find the &#8220;average&#8221; nodal line&#8221; accross the set of bars from the individual node lines found with the salt test above.<br \/>\n<img loading=\"lazy\" decoding=\"async\" src=\"images\/marimba_bars_spaced.jpg\" width=\"450\" height=\"89\" alt=\"These are the \"white note\" marimba bars spaced out as they will be on the instrument frame\" title=\"White note marimba bars spaced and layed out\"><br \/>\nAfter a decent amount of measuring from this set up I was able to determine the exact frame dimensions needed to correctly support these bars. I won&#8217;t go over the whole process here as it&#8217;s a lengthy one, but it will of course be available in the building guide at <a href=\"http:\/\/www.makeamarimba.com\">www.makeamarimba.com<\/a> once the whole instrument is finished and the guide written up.<br \/>\n<br \/>\n<img loading=\"lazy\" decoding=\"async\" align=\"left\" src=\"images\/5_octave_marimba_frame_stage01.jpg\" width=\"217\" height=\"536\" alt=\"Stage one of the marimba frame roughly completed\" title=\"Stage one of the marimba frame roughly completed\"><br \/>\nAs I had already designed the frame earlier in the year, I was able to begin on the frame as soon as these dimensions from the bars were obtained. Of course it takes a fair bit longer than it should as I&#8217;m taking extra time to take photos and write the process down as I go. Nevertheless, frame building is a welcome relief from working on the bars and goes a whole lot faster. This weekend I put in a couple of &#8220;half-days&#8221; work, and have cobbled together the basic structure of the frame &#8211; at least to the point where it can stand upright! &#8211; photo is to the left.<\/p>\n<p>Hopefully there will be some time to make more progress during the next week.!<br \/>\nJim McCarthy<\/p>\n","protected":false},"excerpt":{"rendered":"<p>G&#8217;day again marimba enthusiasts!
