Barry completely customised his own frame for the P524 project, and came up with his own bar post design as well - beautifully milled! This great build should never sag and looks like a solid design all over. Practical and good looking.

Hi Jim, at long last, I finished the 5 octave marimba! The only thing I am worried about is that the low and high notes do not sound as "vibrant" as the middle ones. Is this normal? or perhaps my hearing is the problem ( I am getting on in years). I have only used a couple of home made mallets, one very soft for the low notes and a medium one for the rest. How many mallets should we use for 5 octave instrument? I have checked tuning with my Peterson tuner and also a couple of other brands, all show pretty much the same frequencies (calibrated at 440 Hz.) with external tone generator.

I used a Bruel & Kjaer precision sound level meter in conjuction with a sweep tone generator for tuning the very high resonators, seems to have produced a good result as far as the Peterson iStroboscope software is concerned.

Regards, and thanks for all your help during the project.
