And so...it begins. This is the first in an ongoing thread where I'll document the construction of an isolation cabinet for my small tube amps. To clarify, this is not for a speaker cabinet. I will be putting my whole amp in this. So, it will not be thoroughly sound-proof, as I'll need to provide ventilation. It will, however, greatly attenuate the external sound. So, here goes... This shot just shows the framing members after I cut them to length: I decided to join the members using lap joints. To make things go faster and improve consistency, I built this little rig to lap the end of four pieces at a time. You can see I already have the ends done on one side: Here are the frame members all lapped. You can see how much sawdust this creates. Sorry for the blurry pic. Here the frame is glued and nail-gunned together. It is sitting on the birch ply that I will use for the sides, top, and bottom. I'm getting ready to trace the floor in this pic. Finally, this is a shot of the rough-finished floor. The slot is to allow air to enter the cabinet from the bottom. I will be installing casters so the air can get to the slot. I'll put a slot like it in the lid when I get to it. So, that's all for now. Stay tuned!
