Having moved this past winter the shop went from a dedicated building detached from the living space to an area in the basement. While the room is isolated from the rest of the house HVAC, noise and dust mitigation was mandatory by spousal decree.

The frame is 3/4” Baltic birch and the plex is 1/4” I first started joining with pocket screws but didn’t like the result so I went to half lap joints. The end panels are removeable in case I want to work on a longer piece of wood. To make sure the noise is cut down I made each a double pane with a 1/4” space between. Gluing the plex in place was a challenge. Finally settled on 3M P5200 marine adhesive.

I wanted the front of the top to also hinge up so I don’t have to climb inside when setting up or changing bits. All I have to do is lean in. The double pane 1/4” plex is very heavy and the joint between the top and front panel was joined with biscuits. The first time I put the hinge on, the joint failed with a resounding crack and crash. The next version I said “OK no more messing around” and it had gussets, screws, and re-enforcement blocks. Nothing subtle or elegant about it. Then I found the first pair of gas shocks were only 22 lbs and didn’t come even close to holding up the front. I finally settled on 50 lbs. units and they hold it up, but not by much.

Added some LED lights inside and some weather stripping to keep it tight. Cuts the noise down so that you can converse with a normal voice while standing right next to it. And all dust is contained inside. I haven’t added dust collection yet and may not. I ran a 1.5 hour job and the dust build up wasn’t too bad and the heat while noticeable was not excessive. It’s been way hotter when I had the dedicated shop and all the doors and windows were open and a Minnesota humid summer day of 95+

Best of all the spousal decree has been met. Everyone is happy

my concern is “air-flow and heat build-up and dust…” Yet if it is working for you? then great.
I wouldn’t go this route.
