lew Posted December 8, 2014 Report Posted December 8, 2014 This part will cover the glue up and trimming of the inserts for the rolling pin. I found it easier to glue if I oriented the blank with the diagonal cut facing up. In this picture, you can see the three strips to be glued into place. They measure 2†x 10 3/4†x 1/8â€. Test fit the pieces first to make sure they will seat into the slot. I originally used an old restaurant cutting board as a gluing work surface and pieces of the cutting board as culls and pads. More recently, I substituted a Corian counter top cutout for the work surface. It is more sturdy. On my first attempt, I didn’t use enough clamps- using more clamps and culls assured that all of the joints were tight. I probably overdid it with the amount of glue. A liberal coat over all mating surfaces. Clamped up After the glue has dried and the clamps removed, the blank is ready for trimming. I made a special jig that holds the piece above the saw table. Trimming assures the piece will sit flat for the next diagonal cutting operation. Blank is raised above the saw table. Trim the blank, rotate and re-clamp Trim, rotate an trim again. At this point it is a good idea to “sweeten up†the layout lines, if the trimming operation removed them. ALSO: IF YOU USE THIS TRIMMING METHOD PLEASE REMEMBER TO LOWER THE SAW BLADE BEFORE CUTTING THE NEXT INSERT SLOT (don't ask how I know this). EDIT: I found it easier and quicker to do this trimming operation on the band saw. It is just as accurate and doesn't require a change in the table saw blade height. Now it is just a matter of re-mounting the blank on the diagonal cutting jig and repeating the operations for making the second diagonal slot. The diagonal slots, glue ups and trimming operations are the same for each of the remaining three sides. A slightly different pattern can be made by changing the sequence of cutting the slots. I cut the slot on side 1 first, then rotate the blank to cut side 3, then side 2 and finally side 4. After the four sides are cut, glued and trimmed. On the lathe, ready to be turned. The final dimensions on this rolling pin were: 20†long; diameter at the center: 1 9/16â€; diameter at the ends : 1 1/4â€. I have tried two types of tapers. One started at the center and continued to the ends. The other starts at the ends of the ellipses and continues to the ends. Personal preferences will determine the tapers. In Part 5- turning with a special taper jig. Quote
