thanks frank. this is a one time thing so going to try it. it does not need to be a great thread just kinda. .
 
written and in the "book" as suggested. thatnks again, it actually worked like a charm. finger screwed the dang thing together even. its a nozzle holder for a beeswax extruder.
its now beer thirty and after that, back to making some nozzles and a threaded end cap for the screw and piston assembly. im going to cheat and buy a threaded rod. there just ain't enuf time in my life for all that. . . . .pix when its finished. . .
oh, thanks again. . .
