The bare walls didn’t look like the inside of an old wooden building. Having the use of a laser cutting/engraving machine made producing the inside wood panels a relatively easy job. That is after I made up the drawings.
Once the panels were glued in place it was time to cut the notches and fit the roof joists.
In order to give the inside walls a bit of age, it was time to apply some MinWax stain. Easy job except that stuff is really smelly!
