This is what I have in mind. Just the z-axis is enclosed, the enclosure could be filled with flame-retardant sound-dampening foam (yes it does exist!), or some other wadding. Please excuse the rendering, but you can just make two baffles between the intake fan and the router spindle. These *should* allow air in, but reduce the sound out, due to the sound not having a direct "line of sight" exit path. Of course there will still be cutting noise, but that can be damped with the use of a rubber skirt, or maybe a brush type skirt that will easily flow over the workpiece. The biggest drawbacks will be the lack of air reaching the router, but how much does it really need, I have no idea to be honest! Comments appreciated. |
