Hmm,Thanks for the input fellas.Now i really wanna do this,sounds like a challenge. ive done a couple of elevator shafts and xray rooms in 1’thick drywall it had a layer of metal inside aswell. most of the time it was two layers some walls required three for fire rating and always over lapping the last seam.I may do somthing like this with mdf like @dtilton71 did but i may do layers and add sound proof stuff inbetween the layers as i go.Ill have to decibel it and report back (thanks for the idea Dustin),
@markwal (baffle for exhaust and line it with sound dampening foam.) ?? Do tell…what do you have in mind for the process or any links for the thought?
Thanks for the advise but im going to stick with the vac for now.It was a gift and it has just sat here needing a job to do,its just to big to tote around so im always using the little one,ever since the enclosure it has had a home and it does its job well.But when it finally dies i may decide to go the harbor freight (green) route.I already have mdf on hand and the noisy sob of coarse,small trip to the depot should come together with little as possible spent.at this point even if it was a tiny bit more quiet would be a great start,Im finding most of my run time is in the evening very very late evening and the shop sits closer to the neighbors than me and im afraid the noise may be to much.No complaints yet so im thinking if i just do a little somthing ill def be in the clear.
Thanks everyone please add more if you come up with somthing
