I know about using bird shot, bb's, short brads, small pieces of broken glass, even course sand to prevent the pieces from sliding around. But I just watched a video where he(sorry pc incorrect) used tablesalt sprinkled on the glue for the same purpose! Has anyone heard of or done this? Wouldn't the salt cause deterioration of the wood fibers? Wouldn't sugar be a better option? Personally I wouldn't use either one! Hmmm, how about "Grapenut cereal"? It's hard enough to break teeth!
I found these pretty neat little things called 'dowels'...
I never got good results using salt on scarf joins. I did ok with clamping the pieces together on a sheet of melamine covered chipboard and with using toothpick dowels but these days, for simplicity , I just use a big spring clamp to hold things sideways in allignment, then I put two staples in the top surface. Then clamp good and hard. After the glue is dry I remove the staples, add side cheeks, plane and sand level and cover with a face plate.
