I have basic wood work ability. Just got a router and am hoping to use for the joinery of a toy box / bench I want to build. What is the best method for joining to form the box? The types I am considering: butt biscuit joints, edge mitre joint with spline, lock mitre joint, or rabbit joint ? Looking for simplicity with enough strength for a decent sized toy chest... Thanks so much! Just not sure..rabbit joint looks easiest but wasn't sure if that was appropriate for a large toy chest. What you think?
