There are 10 curved pieces needed for this crib. I needed one jig for the end assembly and another jig for the headboard assembly.

I used 2 sheets of ¾ inch particle board to make these jigs. The first thing I needed to do was make patterns out of poster board. I then taped them onto ¼ inch masonite and cut them out.



These templates were used to rout the first board of each size. Then the first boards were used as a template for the rest of the boards. I put the template on the bottom of each new piece to be routed. I clamped them together and used a flush trim bit with bearing. (Once you rout through the board, you MUST keep both pieces together; the top half and bottom half will fit perfectly together.)

The slats in the ends and headboard assemblies need to fit tight to the curved pieces. I used the same pieces for the jig that will form all the curved pieced. I laid out the spacer blocks, working from the center out, making sure the spacers hang over the curved edges. These will be routed off to the contours of the headboard bottom and the end assembly’s top. I need to order a longer bit to do this.




I continued putting pieces together until I got 5 layers. I used the combination square to keep the layers even. The most important edge to keep square is the contour edge. I marked them so that they could not be turned over by mistake. I would hate to be gluing up the strips and find out that one of the sections had been flipped over and they did not match.

I used a cloth tape to measure my curved pieces. All the curved pieces are going to be longer, then cut to fit during the assembly.

Now I am ready to get the cherry wood and start cutting strips into the different widths and lengths I need. I am guessing I can go with ¼ inch thick strips for the glue up. I will need to play a little to see what thickness will work. The next blog will cover the glue up of the moldings and trim pieces.

Thank you patron!

I know I could have glued up stock and cut the pieces out. You would have to cut them out on the band saw and try to sand them smooth.

Extra work? I felt it would take me less time (4 hours) to make the jigs than doing it this way.

Cost? I also wanted the curved pieces to be consistent in thickness and have a way to cut the curves on the ends of the slats. In order for me to do this, I felt it was justified to spending the extra money.

and you have right on jigs for future builds !

( fix the thinner jigs ,
not all the finished pieces one by one ) .

much more accurate ,
and less hair pulling and fixing !

Curved Pieces : 2- #11 Finished width should be 4 1/2, not 10 3/4. Note : Check all dimensions before you build.

patron: It looks like you are the only one with a comment. As this goes along, please feel to add something I might have forgotten. I would appreciate your expertise. What are the consulting fees these days?
