I'm making a cabinet dresser much like this in mdf carcasses and tulip face frames and doors. Like the photo below how should I go about doing the posts and skirting, I don't have a spindle moulder. Thanks

You can purchase pre-kerfed MDF, kerfed either along or across its length., which could be used for the corners. The plinth corners are probably best formed from solid blocks of wood, cut and shaped to suit.
Thank you. I will be using tulip Wood and have bought a ball nosed router bit for the table router so that and the kerf calculator I will give it a go.
