Paul I have the Nova DVR and it came with a 12" tool rest. I went to Woodcraft and bought a 4" and 6" tool rest. I bought 1" posts for each one as I don't like screwing and unscrewing to change the rest. These are the ones I got and they work just fine for getting in close. The one for turning boxes works great when getting inside with a scraper. You can get right up to the bottom and don't have the scraper hanging over the edge way out there.
