Layout
The people at the clinic wanted to use their logo which they d supplied to me. I converted the jpg image to vector lines and edited them to make a smooth image. I wanted to make the logo textured so I used a simple wave model from the Vectric clipart. The wave pattern was loaded in the background, a depth set and then cropped it to the logo vectors.
Cut AndCNC
I didn't include images or video of the actual machine running. There are many videos online if you are interested in seeing what these machines can do. I pre-sized the pieces on the table saw before taking them over to the CNC router.
Assembly
The person wanted the clock to have a thick profile so I cut a ring from the same 18mm thick material and attached it to the back with wood glue an 1-1/4" flat head wood screws. A french cleat was added to the back for hanging. The cleat that is fastened to the wall was pre-drilled for 16" OC. A heavy clock should be fastened through the drywall and to the studs. Everything was sanded to 180 grit.
Finishing and Letter Painting
The entire piece was wiped down with a microfibre cloth to remove all dust particles to prep for finish. A cost of PolyX was applied and left to dry overnight. The clock was then sanded with a 320 grit sanding sponge and then wiped down wit a mirofibre cloth. The second coat of PolyX was applied and left overnight to dry.
After 2 coats of PolyX were applied, I started to apply the paint. I always seal the wood before I paint to avoid colour bleeding into the wood and causing the edges to look blurred. I blended a brown and black acrylic paint together and added some water to make it more of a wash. I used an artist brush. If the board is sealed with PolyX you can wipe exess paint off easily as long as you do it immediately.
A final coat of PolyX was applied. Always check between coats to see if more sanding is required.
Finishing Up
The clock mechanism and hands were installed. Here is a very helpful video on this.
I included some #8 wood screws to attach the cleat on-site.
