thanks, gearheads, i didn't consider the support of the threaded rod when asking about the motor mounts; obviously a critical consideration...
even though i bought JOHN CONRAD KLEINBAUER's plans, i am going to deviate from them because i am making as much of a junkyard machine as possible... (all of it scrounged but the motors, controller, s/w and roller blade bearings...) i understand how he has (more or less) engineered his machines to work fairly well as designed; but certainly the general design is amenable to variations that should work as well (or better ?)...
i guess it will be easier to spring for a couple bucks for the tubing/hose clamp couplings that are proven to work satisfactorily; besides, i *do* already have a couple dozen hose clamps buried in the shed somewhere... somewhere...
since i got she-who-must-be-obeyed to pick up some lag bolts last night, i can go out and attach the new drill press to the shed floor and finish setting that up... just came up with an idea (okay, i copied the method of a cheap mitre box i have) of using a shopmade cam clamp as holddowns for the stock on the moving table, and the drill press will make the job of making them pretty easy...
even though i have yet to do a lick of work on *this* machine (other than the exhausting tasks of daydreaming, sketching, and imagineering), i'm already thinking about the next one... let's see, if i use I-95 as the X-axis, and I-10 as the Y-axis, with the Space Shuttle gantry for the Z-axis, that will give me an effective area of 300 miles by 200 miles by 150 feet ! ! !
i can cut out my own little state ! ! ! hhh
...okay, step away from the cnc forum before somebody gets hurt.
