The twins are coming along well. The four sides of both base cupboards have been dadoed, rabbeted and sanded. The cut-outs have been roughly cut with the jigsaw. Since I was making four identical cut-outs, I made a template and used the router with a flush trim bit and then I rounded over the edges with the trim router and a 1/8" radius roundover bit.
The whole projects should start on my website soon, with all the details, closups and videos (as usual), after the twin bookcases will be completed and posted. AW readers are at the front seats!
