And don`t use the fence as it is now,put a piece of hardwood there,if you don`t have, you know where I live.
It is never square to the table,with those 4 holes you can put a woodfence and adjust the squareness with kitchen alu foil.Lasts forever.
You can also build a sliding fence,just 2 Mdf boards both sides of the blade with a long fence 90deg to the blade
But your first jig must be a 45deg cutting slidingtable,
basicly a big Mdf board that run in the right tablegroove with adj 40-50 deg fence 600L x 100H x 50W mm.
