Doll Cribs

Our grand-daughters are at the age where they love to play with dolls. They are infatuated with the American Girl style 20″ dolls, now adding the American Girl Bitty Baby 15″ dolls. To go with them, they want additional “furnishings” beyond the cases I built last year. A couple of them have their hearts set […]

Isla’s Bed – Completion

After staining, I waited a couple of weeks to let the stain fully dry. The reason being that the gel stain used is oil based and with the winter weather, I needed to use a water based finish. My favorite for spraying in the winter is General Finishes Endurovar. It generally flows out well and […]

Laser commissioning / to do list

With the laser in and basically running, there is still more to do to get it ready for “production”. I did the first pass beam alignment but did not check the exit beam at all 4 corners. Up to Mirror 3 it is good at all 4 corners. Near the center of the bed it […]
