In this video I’m showing how I fill a knot hole with 5 minute epoxy resin coloured with the sawdust of the wood for a close match.

Thanks for dropping by to have a look.

Thanks for the video. I do the very same thing often to repair knots and other defects in the gunstocks I carve. Sometimes black epoxy mixed with the sawdust makes a more invisible repair. It just depends on the color of the wood around the defect. For smaller pinholes, I use sawdust and super glue. I just fill the crack or hole with sawdust as I’m sanding and use thin super glue to flow through the sawdust and make the defect solid all the way to the bottom. It makes minor defects disappear. I’ve not covered the surrounding area with masking tape, I usually do the repair before any sanding so there is a lot of extra material to sand away.

The chair you are working on looks fantastic. Every time I see a sculptured chair, I see the same curves I carve and sand into gunstocks every day. I’m going to have to make a couple of sculptured chairs soon.

In this case the knots didn’t need to be filled, so I asked and was told they would rather have the holes filled so the holes were filled, thus all ready sanded.

Also I think the tape keeps the epoxy from getting squezzed in the pores of the wood.
