gabjr, i took a stove bolt, adhered a piece of thick rubber mat to it,(rubber roofing would work as well) i got my rubber at hobby lobby.i think it is for cutting things i dont know for sure.then i took more of the mystery rubber and mounted them on a plate that fits in my vise that is shaped like a t so i can grip it.then i took another bolt and mounted it on the plate. take 2 pieces of pvc that barely fit over the bolt and glue them together side by side. slip one tube over the bolt (to hold it at 90 degrees),and slip your pen in the other.mount the stove bolt in the drill press, and viola a homemade pen press. hope it helps rich
