The spindle sanding bit for the drill press is not that expensive. Your drill press table probably has a slot to remove, for drilling through holes. just remove that slot for the sanding bit to fit down in, allowing full use of the spindle sanding bit. The drill press is designed to go up & down, so this would put a side pressure on the press, possibly shortening the life of the bearings on the press. Occasional use like this should be alright. Purchasing a oscillating spindle sander for around $150 is the better way.
