    Default Ring Cutter Vases

    G'day
    A few years ago I aquired a Leady Ringcutter .This is a device, designed by the late Bruce Leadbeater, to cut rings at an angle from a flat disc cut from a board .The rings are then turned over and glued together to produce a cone shape which is then turned into a bowl .I made a few bowls using it ,but was never real happy with the shape of the bowls which was constrained by the cone shaped blank .
    Bruce showed some pictures of vases on his web site made by glueing two bowl shapes together ,so I started playing around .
    I started with a disc about 260mm x 20mm thick ,cut on the bandsaw and hotmelt glued a tennon on . I then mounted this in a chuck , trued up the diameter then using the ring cutter, cut the corner off at 55 degrees and discarded that ring . I then cut two more rings at 55 degrees 12mm thick, with the ring cutter . See picture .I then hotmelt glued a tennon onto the remainder of the disc while it was still in the chuck then remounted the disc on this new tennon then turned off the old tennon .This is now the base or the neck of the vase .I then glued the two rings onto the base, trueing up the edge and face after each glueing . I found this was easiest to do by removing the chuck with the base in it and just using the weight of the chuck to hold the rings in position untill the glue had set .
    I next cut a disc from the original board, slightly larger than the cone glueup above and glued a tennon on it . After trueing up I then used the ring cutter to cut a ring 12mm thick but with the cutter set at 90 degrees . I then glued this ring onto the cone. Next day I did a preliminary shaping . I felt it was safer to do this while I could see the inside and I could judge how much wall thickness I had to play with .
    I then repeated the above proceedure to make the second half of the vase .
    I now glued the two halves together by mounting one half on the tailstock .see picture . I then turned off the tennon on the tailstock end then bored through .The neck is made from a series discs cut out of the offcuts and just bored through as I built it up.
    I now made a smaller vase using the remains of the discs used to supply the 90 degree rings .
    I was pretty happy with how these turned out and the use of the 90 degree rings in the middle enabled me to produce what I think is a better shape.
    I decided to have another go and this time I made my board by glueing together a couple of bits of cypress floorboard with the T and G cut off, that I picked up from a council roadside cleanup . This time I only used one 90 degree ring at the junction and changed the profile . I think it turned out OK .
    I don't know what the timber was in the the first two vases . It was a shelf from a bookcase that I bought from a second hand furniture shop about 60 years ago .
    The finish is DO .
    Comments or questions welcome .

    Bruce came up with some pretty clever gadgets. When I bought a lathe from him he showed me the ring cutter in action. Pity I never got one at the time. I did get his chuck and and a few other bits n pieces. For anyone interested Mcjings have a version of it.
    The vases look good and a good way to use up offcuts.
    Regards

    Default Bruce and his gadgets

    Yup, built my own similar design to his. But never got around to using it, ended up giving it away to Woodnut in Clarence Town and I doubt if he has used it either

    The problem that Bruce was solving with his ring cutter was the nature of the timber supplied to schools, viz standard board sizes. Up bush we could always get a lump of wood if we wanted to make something larger, but in city schools that wasn't an option.

    BTW, Bruce and I grew up in the same small country town, which still had its own timber mill during my childhood. Bruce was a generation older than me, so the only contact I had with him was when he taught me 'manual arts' for awhile in the local school. Clever man, but I probably learnt more about working with wood from his father.

    Well done Ted, reading your post reminded me that there was one in the shed somewhere. As a result i dragged it out and had a play. I made a few very thin, transparent, lamp shades. But as you said, the finished bowl wasn't very exciting so the "tool", went into the gadgets to ply with later.
    Can't remember where the unit I have came from, but it has "Ring Master" written on it, I suspect it was made in America. It would have to be about 35 years old, I acquired it without the instruction book, so I was at a disadvantage.
    Nice to see you pushing the boundaries a bit. I like what you have done.

    So that small town was Alstonville where there’s a Leadbeaters lane.
    I worked with Bruce and years later Michael at STC.
    I remember Bruce mentioning a lineshaft workshop back home.
    I knew the building from driving thru every day on my way to work at Ballina slip.

    Yes, that was Alstonville.

    That lineshaft was in the old Norco factory that you would have driven past every day on your way to and from the Ballina boat slip. Bruce's father worked there at the factory on mechanical maintenance back when it was in operation. My father also worked there for Norco before WW2.

    Later on Bruce's father, Horace, established a wood workshop in the old factory after Norco ceased operation there. I spent a lot of time in that workshop when I was a kid picking up (mostly by osmosis) some of the fundamentals of working with wood.

    Bruce got some of his inventiveness from his father, who adapted a small car gearbox to provide dynamic speed control for his wood lathe; as it were MVS long before EVS. That certainly beat stopping the lathe to change the belt every time you wanted to change the speed!
