About the MultiMachine

Filed under: — pat @ 3:12 am

Take: 2 old engine blocks, 2 pieces of pipe, 4 import bearings, some steel plate and a $69 crossfeed table.

Add 2 hours of machine shop work and a few minutes of welding, drill a whole bunch of holes and end up with an accurate metal lathe (with an up to 2 1/2″ spindle bore) that also end and horizontal mills, drills or bores in 3 or 4 ways, chop saws, surface grinds, spins and can be a cheap and rigid CNC platform with all these functions.

It’s rigid. The MultiMachine uses 2 full size engine blocks solidly clamped together with 1/2″ x 12″ steel plate and (4) 3/4″ clamp bolts. This makes it almost “chatter” proof but is still easy to dis-assemble into managable pieces. The built-in “crane” makes re-assembly simple.

More…

  • Fits in a space 2 1/2′ x 4′ (or less with a smaller table)
  • Uses an inexpensive but accurate 30 to 60 lb. spindle assembly with a chuck thread, register and shoulder that are finish machined in place for accuracy (without change gears!)
  • The 250+ lb. vertical slide can be raised .0001″ (thats right, it’s no typo!) at a time and does not move when the clamps are tightened!
  • Make a spindle big enough to bore an engine block or small enough for model making. Add a tool post grinder and work on a manhole cover!
  • Even use a heavy 8″ 4 jaw chuck (at low lathe speeds).
  • Put the the crossfeed table in a pan for a clean way to use coolant.
  • Power it with anything from 3/4 hp electric motor to a 15 hp gas engine or a tractor PTO.

Best of all

After you find all the needed good junk, get 2 or so hours of machining done. Then after that, all that is needed is a drill press to finish your MultiMachine. Spend an extra hour in the machine shop letting them drill and counter-sink the holes in the heaviest parts and then all you need is a strong 3/8″ pistol drill to finish the whole thing. When it’s finished you have all kinds of new ways to make holes and don’t even need a drill press anymore!
