i haven’t seen this mentioned but as i’m only a few month member i could have missed it but i had tiny gaps in a half blind dovetail. the joints were almost too tight to work, these were not full gaps. it looked like very thin slivers came off the edge of the male & female tenons when tapping it together, ok it was a bit more then tapping. i hate any gap so the idea i saw in a video about wet sanding pen blanks with 150 grit & medium or thick Ca came to mind. i got out my sanding block, some medium CA and a somewhat used piece of 150 grit. a minute later i had no slight gaps with no waiting time for gap filler and it was sanded. these gaps were no bigger then a pencil line and they were sporadic along the joint line. the best thing was it matched exactly in color unlike mixing epoxy and sawdust which i always find to be a bit darker then the wood. i think if they were even a bit bigger 120 grit or 100 grit would have done the same thing. just thought i’d pass it along.

Thanks for the tip, Bill. I will try this the next time I hand cut dovetails, although with the results I have been getting I may need something larger than sawdust to fill my gaps. :)

Well, I never have gaps to fill in MY dovetails so I wont need this tip….....................

So did you say to use thick CA and 150 grit?

OK, I’ll be the goat for all the others who don’t know either: what the heck is this ‘CA’ that is so commonly known that it should be recognized by its initials?

CA = Cyanoacrylate, commonly known as SuperGlue.

Sometimes it is possible to saw a new kerf that is large enough for a sliver. Scary.

CA glue is some great stuff, it comes in thin, medium and thick. There is also an accelerator for it, one draw back about using the accelerator is, it sets so fast it will oxidize the surface leaving a white power. There is also a debonder available for when you glue your fingers to your project.

Woodcrafters has a good supply, I get mine from my local model airplane hobby shop.
