Whenever I get a new blade for my table saw, I generally make (or buy) a new table saw insert so that I have a zero-clearance insert to match each blade. As you might imagine, I have accumulated quite the collection of table saw inserts over the years. In order to better organise the inserts, I made the handy caddy you see above.
PLYWOOD PROJECT. The front, bottom and back have aligning grooves. I cut all of the grooves in one oversized piece and then cut the three parts to size. Cut 19mm-wide rebates in the front, sides and back before assembling the caddy with glue. For clearance to install on a pegboard panel, I chamfered the upper back edges.
