I glued two flat walnut boards together for the bottom and cut a frame in beech for the tray. I routed a groove for the bottom to sit in and mitered the corners.I drilled two holes for the handles and routed the rest out on my home made router table.Had some burning but that cleaned up nicely.Dry fit made me realize I needed to trim the bottom a bit.Using the table saw I made two end pieces with cut-outs where the slats will sit.While the tray was drying (boiled linseed oil) I glued the slats in the end pieces.Aint that grand?
