When I needed to cut biscuit slots in the ends of 3⁄8" slats, it was necessary to hold them dead-solid and centered to keep the joiner’s blade from blowing out a surface of the thin stock.

When I needed to cut biscuit slots in the ends of 38 " slats, it was necessary to hold them dead-solid and centered to keep the joiner's blade from blowing out a surface of the thin stock.

This guide jig uses a layer of MDF and two pieces of scrap stock to form a workpiece-sized slot that guides the slat end precisely into the joiner.
