All i use is the bandsaw, i have a piece of wood with a test cut from the bandsaw, get a piece of wood from the bin, start cutting the veneers using the marker on the guide rail set to just over 1mm (My Kerf Size) try it in the test slot and adjust till i get my fit. I then use the wood i want for the veneers. Just a little tip. Once you get this set up correctly have a look around your workshop at other woods you have and cut some veneers from this, it saves so much time when you next need inlays for the Celt Crosses. Just to add that i never have to use any sandpaper when making veneers this way ..
If you have run off with the bandsaw you will need to make the adjustments needed, there are quite a few good videos on youtube that can help you with this.
