Thanks for the tips so far: it's a PH2 with a starting crank like this - can this a) be removed and blanked and b) is this a good idea? I can't see my daughter cranking it successfully and the tower gets in the way. So far, she has stated 1st time every time
I had envisaged building a metal platform over the top, leaving the sides open, and then fixing a sound attenuating board under the platform. This would leave enough space for air flow, and also it would be hinged to allow access for maintenance. Getting the crank tower out of the way would make life much easier
I was amazed at how much reduction in the noise level was even by pulling the hatch closed and leaving the doors open. Closing 1 door helps even further but both would block access to controls
