    Iíve got a few questions about an old sac shaper.
    I think itís a 1960s model.

    I donít know much about sac but apparently they made shapers for other brands including powermatic.

    Whatís with the spring?
    This is the third shaper I have owned and the first one that had a spring.
    Itís too short, it wonít let the spindle drop all the way down.

    Can I just disconnect it?

    The motor mount is cast iron and part of the bearing housing casting.

    Iíve got a 4hp 220 volt three phase motor for it that Iím planning on running with a vfd from jack.

    I will have more questions later

    Thanks

    Nathan

    Second question

    How does the pulley stay on?
    It has no set screw/any way of attaching it to the motor shaft.
    The motor shaft had a threaded hole, do I add a bolt and washer to keep it from flying off the end??
    Iím feeling like I must be missing something!!

    Thanks

      I bet you that spring is for assisted lifting. Might be harder on that bronze gear if you don't have it on there? That gear looks kinda knackered....I'd price out a new one and see if you can have it on hand.

        Re: Help with sac shaper

        As Brent indicated, the spring balances the spindle assembly mass, and probably works fine with the motor installed.

        The pulley may well be retained by the end cap screw...........Rod.

          Thanks!

          Next question
          The spindle height lock is stripped.
          It looks like someone stripped it, then welded a nut to the cast iron - then stripped the nut.

          Whats my best option for repair?
          1 - cut off the nut and weld a new one

          2 - jb weld on the threads to build them back up

          3 - helicoil?
          ive never used them before so I have no clue how to install one

          4 - drill it bigger and tap the hole for a larger size bolt

          thanks

              cast drills & taps very easily, so you could drill & tap the cast AND the nut.

              if you need a tap, good chance I have it.

                  Thanks Tom
                  Im helping my cousin drywall his basement and heís got a tap and die set.
                  Iíll borrow it (70 sheets of drywall... my back hurts just thinking about it).

                  Im leaning towards helicoil.... mostly because Iíve never used one before and I like trying something new.

                  But drill & tap does make a lot of sense.

                    I doubt helicoil will work for long. They are best for bolts that get secured once and stay there, not constant tightening and loosening like a lock screw. best tap oversize if that is practical.

                      I can't give any better suggestions than you have been given. But i noticed the label on the machine is from Fischer on Cleopatra drive in Nepean. That was Klaus Fischer, he was my neighbor when i had my cabinet shop a few doors down from his. He bought and sold woodworking machinery. He closed up shop not too long after i moved in, I wonder what happened to him.

                        iamtooler Thanks Rob I didnít know that about helicoil.
                        I will drill and tap.

                        hennebury thatís really cool that it came from your neighbor.

                        I got the shaper from Igor - I donít know where he got it from.

                        I have no idea how old it is
                        It has a heavy gauge sheet metal body with a cast top.
                        The fence is fairly basic but seems to work well. I donít know if itís a factory fence or not.

                          If you decide to weld another nut on , suggest you find a grade 10 nut then use a lower grade bolt or set screw that will wear out first.

                            I borrowed a tap & die set and fixed it that way.
                            I donít have a welder in my shop and the thing is just heavy enough that I donít want to drag it to a friends ;)

                              if you ever need, my welder is an inverter style, multi voltage machine. so relatively light, and runs off 110v or 220v, mig, flux or stick.
