Thing are happening! I started today with preparing the speaker cabinet. Since the plan is to put new oak panels in and new speaker driver I need to remove the previous mounting solution.

The back was removed and the speaker dampening material was kept for reuse.

speaker elements out now it just removing the brackets.

Since it was attached using epoxy it was quite a lot of work getting the brackets of the cabinet. Some prying and percussive adjustments did the trick.

One cabinet prepped one to go. after i remove the bracket I had to use a chissel and a sander to get the epoxy off.

Two done. I now used a sander to get a smooth surface.

There are sanders, and there are sanders. I used a mirka deros series sander. Almost built-in dust collection, orbital movement. it´s just a joy to use.

The speaker cabinets now have a smooth finish! Next it was prototyping the front panels. I have not done any two sided cnc jobs before so i made a quick plywood test. the test failed but I learned a valuable lesson. I cannot just use screws for alignment when switching sides. It was not near good enough. My next plan is to make a second sacrificial plate on top of the sacrificial plate that is already there. The sacrificial plate will have a pocket for the material I am going to cut in. This should mean the I will have precise way to fixture the material. Wish me luck!
