Hi Don,

The baffles are removable and repackable. In the past I've made them from 2 1/2" perforated tube. I may need a different design to get down to the noises levels Bernie wants.

The advantage of the removable baffles is that you can tailor the sound to suit the situation/application. I'm making some free flow baffles for Bernie to se on the track and some quieter ones for the street.

I should have some pictures of the completed baffles on the weekend.

Cheers
