  • Well nearly a slotter gloat

    Nearly because no pictures yet, reason is part not delivered yet.

    Last week I had to make a new spline to go in the end of a DC motor where the old one had stripped, 12 teeth involute section.
    So hand ground a form tool and ran up three blanks, only 30mm diameter and 45mm long and set the Ravensburg slotter up to do them.

    Not too bad a job as the inbuilt rotary table has 24 divisions and a dividing head for weird numbers.
    Problem is all slotters are too low, when I had the Butler than Tim has now I stood it on two pieces of 8" girder and it was still too low. The Ravensburg is the same and it really breaks your back bending and falling forward all the time.

    Makes me regret selling the 2 or 3 Bridgeport slotting heads that have been thru my hands at odd times.

    So yesterday this guy who has a workshop close to me comes in looking for some linear rail and carriages for a loading jig on a press, he's also in the process of moving to a larger shop.
    I found a second hand rail and two carriages that came off a scrapped machine and the haggling started.

    I finished up swapping it for a Beaver slotting head he's had for ages, never fitted and can't be bothered moving it.

    So I reckon this fitted to the POS Bridgeport will be idea for small splines with something like a 10" rotary table and leave the Ravensburg for the serious stuff over 3"

    Pics to follow later.

        Thank you to our families of soldiers, many of whom have given so much more then the rest of us for the Freedom we enjoy.

        It is true, there is nothing free about freedom, don't be so quick to give it away.

              Since no one else has, let me quote you on this Bridgeport loving for future fun/teasing and definitely agree that hell has frozen over.

                  Using a POS as a head hanger has got to be cheaper than buying (even second hand ) 20Ft (6 and a bit metres) of 1" x 1" angle to make a propper job.


                  Regards Ian

                  Will it fit a Milford?????
                  You might not like what I say,but that doesn't mean I'm wrong.

                      Sir Johns addition

                      Have you designed something to stiffen the flexible Bridgy , otherwise the slots will be tapered.(as most are ).

                      On a more serious note , pics needed asap , both of the slotter and in use .

                      PLEASE!!!!!!!

                        I could swear when I first glanced at the title it said (well nearly slaughtered a goat!!). But I still would like to see some pix’s too.

                          I initially read "slotters are too slow, so I put it up on some 8" girders"

                          and have been trying to figure out how that makes them faster.

                            We used a Bridgeport slotter head to chisel out the throats of wooden planes that we made for the Historic Area in Williamsburg. We made very stout chisels from D2,and thick saws for cutting where the wedges went. The saws(more like broaches) had large teeth,and were 1/4" thick. They cut clean as a whistle with everything held rigidly in the mill. Used without rigidity,they would have been a disaster!

                            There is a video of Jon and me doing it on the Fine Woodworking web site,but you have to pay to access it,and the other videos there.
