Bigjigs Toys Jar of Wooden Nuts and Bolts - Construction Set

Product Information

The hex heads for the bolt are made just like the hex-nut blanks in step 3. The only difference is the hole is 1.5" diameter, and does not go all the way through. Glue the threaded dowel into the hex head to complete the bolt. In addition to fine motor skills, the Montessori wooden bolts material can also be used to teach children about concept of size and the associated vocabulary of small, smaller, smallest, and big, bigger, biggest. The wooden bolts material is engaging while also providing them with a sense of accomplishment and satisfaction as they master new challenges. Insert the nut blank into the hex-nut holder; and screw the hex-nut holder into the thread box. Install the thread box into the dovetail slide on the router base.

Current estimates indicate that galvanised heavy steelwork that is exposed to UK weather conditions will last in excess of 40 years. ELG: Moving and handling: children show good control and co-ordination in large and small movements. They move confidently in a range of ways, safely negotiating space. They handle equipment and tools effectively, including pencils for writing. You can tell from the pictures that I made some of my own dowels from laminated maple and cherry boards. I also used commercially available dowels made from hard maple and poplar. Hot Dip Galvanised (HDG) screws have a tough, protective layer of zinc which protects the steel fastener from corrosion for far longer than zinc plating. The electrochemical properties of zinc cause it to continue protecting the steel from oxidisation even if the layer is damaged by chips and scratches.

A wooden frame with three wooden bolts and three chunky wooden nuts. Tightening and unscrewing the bolts improves fine motor skills and hand-eye coordination. Take a 1.5" dowel, 12" long and drill a 5/32" pilot hole into one end; then insert a 1/4" lag bolt. This will help with turning the dowel when cutting the threads. Insert the dowel into the thread sleeve and make sure it is firmly seated. You don't want it to slip during the cutting process. Insert the dowel/thread sleeve into the thread box, and clamp the assembly to the router table fence. The front of the dowel should be just to the right of the v-bit. Adjust the v-bit height for a light first cut, e.g. 1 mm deep. Once you have a well-working thread you can cut the dowel to complete the bolt. You may include some unthreaded dowel length for a partially threaded bolt.
