I have made over a dozen Roubo book stands. The biggest challenge is cutting out the space between each knuckle. Roy Underhill uses a pad saw with a hacksaw blade to sort of pull out wood to create a groove. This is an unpleasant task that leaves a messy looking crevice. Others on the Internet advocate using a fret saw. This is also a somewhat unpleasant task and I find cutting a perfectly straight line with the fret saw close to impossible. I have used a 1/16 inch chisel adapting Paul’s morticing method which works reasonably well but still leaves a messy looking groove.
Does anyone have advice or a better method? The powers that be on this website told me there would not be enough interest to have Paul make one as a project.
Hej Gary,
There is a video by Mr. David Charlesworth on knuckle joints. I think it’s called “The Knuckle and Rule Joints”. My access is by a streaming service, but it’s also available a DVD. It’s a two hour long class, which its price reflects.

London, UK; Boston, MAI have had pretty good results with PEGAS brand double reverse fret saw blades . A portion of each blade pointed in the opposite direction. It keeps the edges of the kerf neater.

The best success is with the 2/0SPR
They also work well for cleaning out dovetails.
