I had a long dispute with myself whether to get the JBLs back to the original condition or to get them redone just to match visually better to my room. I finally chose the latter as my friend (the carpenter) said that he can get them easily back to original shape later if needed and nothing reversible will be done.

I do not actually know what they will finally look like as just briefly discussed the main idea with my friend- one internal braze will be added and then some suitable veneer etc. We'll see..
