- | To be avoided. | + | |
- | I had to spend a fair bit of time getting the surface of the base lined up properly after gluing. Lots of sanding and tweaking, and the end result was OK but not great. If I were to do this again, with the same size sheet of ply, I would cut the playing surface out, and cut up the remainder of the board into four corners. | + | This became a running joke in our household. "I'm going downstairs for a bit to put the final coat on the crokinole board," |
- | I'd also make the gutter 1/2" narrower to bring the final circumference of the base down under 2.4m. This would give me one join in each edge strip rather than two. I could also possibly reduce the size of the playing area surface by 1/2" and still have a spec-compliant board. | + | === Dust === |
- | I would get the surface of the gutter to a good state, then cover it with masking tape before gluing on the edge strip. I had issues with glue squeeze-out preventing stain from soaking into the base where there were traces of glue left. This took a lot of fiddly inside corner sanding to resolve. | + | {{: |
- | ==== Playing | + | My first few attempts at a final coat involved sanding with an orbital sander with 240 grit paper down to a matte finish, then a coat of unthinned varnish. The next day I would inspect the dried surface |

+ | I drilled some small shallow holes in the reverse side of the playing surface and very gingerly, by hand, put in a few screws. I used these screws to hang the board angled face-down from the ceiling. The idea was that dust would not settle on the board. I set up a bright work light off to the side so I could clearly see where I'd sprayed already. | ||

+ | === Final sanding === | ||
+ | |||
+ | I had been doing my between-varnish sanding passes with 120 and then 240 grit sandpaper. I bought a new orbital sander with functional dust extraction that I could hook up to my shopvac. My old orbital sander had been repaired and the dust extraction holes were full of liquid nails. With this new sander I could get a good matte finish, but I wanted something nice and glossy. | ||
+ | |||
+ | I have a roll of 600 grit sandpaper, but I found that it would quickly clog when trying to polish up the 240 grit surface. After trying polishing | ||
+ | |||
+ | === Waxing === | ||
+ | |||
+ | I applied a generous layer of pure carnauba furniture wax with a circular waxing sponge thing and left it for ten minutes, then buffed it off. The result wasn't quite as glossy as I wanted so I applied another coat and buffed it off almost immediately. The result was excellent. I screwed in the posts I'd made earlier and left it overnight. | ||

+ | |||
+ | Some guide suggested using steel wool to apply the wax coat. The 0000-grade steel wool I had would readily shed lots of fine steel dust which I feared would end up in the wax and rust over time. I stuck with the sponges. | ||

+ | We modified the rules to even up the game a bit. Alex could shoot without having to hit one of my disks. This was pretty much the perfect handicap for us. The penultimate score was 95 to 90 when he scored an enormous 60 points on the final round and won the game. | ||
