Dents, Gaps and Tears

Joshua Farnsworth recently filmed a video of me building a Continuous Arm Rocker. It should be published by Popular Woodworking in the next month or so. Today I started cleaning up the chair in preparation for painting and plenty of minor things needed fixing. I thought it might make a useful photo essay on finishing.  Here’s the first installment:

Rapsing

The concave side of the arm tends to get bumpy due to compression during bending. The only way I know to completely fix this is to rasp at a diagonal to the bumps, then scrape, then sand.


ripped fibers Somehow, one side of the arm had some torn fibers.

Gluing vertical surfacesThin CA (super) glue will fix this, but the surface you are gluing needs to be horizontal or the watery glue will run everyplace but into the crack.

0790 ripped fibers gluedLet it dry for a minute, scrape it flush, and it’ll look like this.  I probably should scrape away some more of the glue so I don’t see a change in surface texture through the paint.


torn reamed fibersHere some fibers tore loose from the arm-stump mortise during reaming.

puttying reamed fibersPutty fills these nicely —apply it with a screwdriver. If the putty is really thick (almost flaky), it won’t shrink much as it dries. You can cut or paint it immediately after applying it.

Chiseling reamed fibersTrim the putty with a chisel (sandpaper tends to hollow out the putty leaving a slightly concave spot).

0796 fixed torn reamed fibersFixed.


dentA small dent in the seat.  Steam this out.  If you scrape or sand, you will end up with a raised spot when the wet paint raises the dent.  For the same reason, any dents you get during the final scraping process should be raised with steam before continuing scraping.

steamingA wet rag and my new thrift-store iron.  Re-wet the rag if necessary: the more steam the better.

fixed dentAlmost entirely gone after less than a minute of steaming.


Gap around jointSmall gaps like this one around a spindle hole can be filled with putty.  Putty tends to show on bigger gaps, so use medium (or thick) CA glue, or make a wooden wedge and drive it in.
