    Default G’day Guys

    I’m going to use my actual name as my username which is Hugh Venables. I live in Ferntree Gully Vic with my wife Di and my garage. I grew up in Eltham and completed HSC at Eltham High. I was fortunate enough to do a fitting and turning apprenticeship with Repco from 1973. I had a crack at a degree in Mech Eng at Preston Institute of Technology but wasn’t really heading where I wanted to go and dropped out in late second year. Most of my working life has been in the workshop of the department of Mechanical Engineering at Monash University from which I have just retired.

    Some years ago I was able to purchase a Demco Record lathe and a Startrite 24-V-10 bandsaw when Monash’s Faculty of Education wound up its workshop. I mainly wanted the bandsaw for restoring the timber body of my 1930 Oakland but the lathe has been very useful although not of great quality. More recently my son, who also did a fitting and turning apprenticeship but then completed a degree and works in Geospacial Science, go figure, and I went looking for a versatile mill like a Deckel and ended up with a much more affordable X8130. Nowhere near the quality but with all accessories a very useful machine. As I was about to retire the precious petals my work colleagues got spooked when the camlock chuck on the very nice CVA lathe (1966) occasionally came loose and decided to scrap it so I got it! It is about 900 between centres but weighs 1500 kg, a bit tricky to move but is now where the Demco was and I have repaired a lot of oil leaks, the spindle brake and very likely the chuck loosening problem. See ya round Guys.

    I had a CVA and I dont remember there being any kind of spindle brake you just flipped the motor into reverse. Any question ask away I had mine fully apart a few times.

    On this CVA there is a rotation detector on the motor shaft that, on rotation, closes a set of contacts that are in series with the normally closed contacts in the contractor that is switching the rotation and the contractor coil for the other direction. When the rotation is switched off the opposite direction is automatically switched on until rotation ends and the rotation detector contacts open. The rotation detector has a motor driven drum that rotates around a magnet that is drawn around. The magnet has a peg which is trapped between a pair of spring loaded levers. When the peg pushes against either of the levers the contacts for that direction close. I guess a brake is not the best description.

    Thanks Grahame. I have a message from Neil asking me to go to SETTINGS to make sure my email address is up to date. I haven’t been able to find SETTINGS.

    Thanks Grahame, it looks like I wasn’t looking for SETTINGS at all. My email is fine but the message is still there. I’ll just ignore it.

    Hi Hugh,
    Im a patternmaker by trade and have also spent a decade or so in Uni workshops/teaching labs. Made sure I left in good graces with the senior T.O.
    They had a lot of nice equipment back in the day.
    They are wary about ohs probs with selling it to the great unwashed nowadaze so just dispose of it.
    Did you have to lift your lathe out of a skip or did it fall into the back of your ute/trailer.

    Hi clear out/H,
    I hear what you are saying about the great OHS fiasco almost all of which is just an enormous cost to industry and a waste of time and effort. The last raid we had by Worksafe required that any cover on a machine had to have a tool to open, not just a hand knob so the person with the wish to damage themselves had to go and get a tool to remove the cover. In the case of my CVA the top cover on the back of the headstock just sits there but had a hand knob catch which had to be altered to a smaller diameter that needed a hex key. The end result of this piece of official brilliance was that no one bothered to get the tool to secure it and it just sat there unsecured. Unfortunately that allowed it to fall off the machine on the truck on the way home and was damaged.

    I was a bit lucky. I was the CTO and got on exrtremely well with my boss the Resources manager. He organised for the machine to be written off and had no objection to me taking it. One of the guys put it onto Cranetruck Joe’s tiny crane truck that was small enough to get through between the fence and the house at home with a jib on a forklift and left the bars and chains on it for lifting it off. Joe also loaned me a perfect pair of skates that I could use to move it from the carport into the garage.

    But the paranoia with disposing of apparently potentially dangerous equipment according to the untrained and largely ignorant has caught a magnificent disc sander with 900mm wheels on each end of an enormous electric motor and tilting tables that was declared unsafe by the University’s OHS idiots and condemned. Then the head of that section was determined that it must be scrapped. I suggested to his second in charge that we should tell the scrappy and the interested pattern maker to get together and he said that would be dishonest. What an idiot. I greatly regret I didn’t do that myself. I might have got my wrist slapped but I was retiring anyway. It would have been sad if they decided not to let me have the CVA though.
