The first thing I recommend, is watching the video for insight and important aspects that can’t be reached through a static document or text.
In order to setup the default cut layout, simply click the “Open in Easel” up top
Using ½” dowels, cut two 3” sections.
Using your drill, put the dowel into the chuck.
Use the drill to sand the dowel to a slightly loose fit to the wheels and a loose fit to the car holes.
Using the dowels glue one wheel to each and let set.
Put the dowels through one side of the car and lay flat.
Run glue around the body and drop in some kernels to fill only one cavity and then take some away.
Put the body together and clamp while keeping the dowels in place for alignment.
Once the glue up is clamped and good, remove the dowels to avoid them from gluing to the body.
Let sit for at least 4 hours
Glue remaining wheels onto dowels, cut and sand any remaining dowel
With 100 grit sandpaper and moving up through to 320, all the edges are worked down and the surface should be completely smooth for a babies touch.
The inside isn’t too important to sand, but I’d recommend using at least a 150 for better gluing.
