    Default Seeking a good turn from a local member with a lathe!

    G’Day all,

    I have a need to turn a 1/8” slot into the two weight pulley wheels for my clock.

    The plans recommend a lathe or laminating different thickness ply, but I cut them out of the 1/2” ply thinking I could use my router.

    I’m not keen now to dice with that!

    I have a friend in Queensland who would do this for me in a flash but I really want to at least be there - if not get a quick lesson on how to do such a simple job on a lathe so I can do it myself.

    So, I figured I could put the word out to see if any members are local enough to me to help out.

    I’m on the upper north shore of Sydney (Tuzza)

    And flexible during the day at the moment (between jobs and desperate to get my clock ticking before I start Mum next one)

    If anyone can help I’d sure appreciate it!

    Here are the wheels


    The dotted line indicates the channel depth.

    I’ve not done any finishing on the wheels yet; straight off the scroll saw and a turn on the disc sander to get them roughly equal and round.

    Best,
    Will

    If you don't get any offers, something simple like that could be done in the drill press. Think of it as a vertical lathe. For a tool rest, mount a bolt onto the table, you could use an ordinary chisel to do the grooves. Practice on some blanks first, to get the hang of it.

    Hi Kryn, this crossed my mind actually but I was uncertain about it - i figured if I tried it with any of my tools it would just dig in and gouge.

    What tool would I use to cut the slot?

    Do I get a narrow kind of chisel with a particular end or something?

    Will,

    try contacting either of these clubs, they would be happy to help im sure

    http://www.snbwoodturners.com/ - these guys are at Narrabeen

    or Western Sydney wood turners at Lalor Park - Western Sydney Woodturners - About Us

    6 of one as to which will be closer to you. Although this probably should be put in the wood turning section.

    cheers

    Richard

    Are you particularly attached to those wheels?

    Spinning them on a lathe is rather risky, now that you've cut out the central fretwork. Particularly with cutting into ply "end-grain." It would've been better to have the disks rounded and turned, then cut out the spokes.

    How were you planning on rounding them before you though of turning? Mounting on an axle in a jig and then using a linisher? The same sort of jig should work reasonably well with a router... taking several passes that only remove a mm or two of depth each pass.

    Personally I'd probably temporarily attach another layer of thick ply on the top face, just to keep my fingers that much further away from the router bit if I felt - for some odd reason - that I needed to hold the piece close to the router bit.

    FWIW, if you still want them turned and can't find anyone closer than Oberon, I'll happily spin them up for you. Under the caveat that there's no guarantee you'll get anything more than splinters back.
    I may be weird, but I'm saving up to become eccentric.

    That all makes good sense.

    I accept I’ve got the order wrong on this one.

    I have various options when it comes to jigs I use for turning the wheels against the linisher disc.

    I should spend some time perfecting these so I can adapt to the router.

    This is one tool I have tremendous respect for but not enough experience to have begun to develop confidence.

    It would be a trivial excercise to cut the groove on a saw bench vertically.

    Thanks to John, AussiePens who pointed me in the right direction, lent me some slot cutters and instructed me on how to set up my router with a zero tolerance fence.

    This has been a great learning exercise and gone some way to building confidence with my hitachi and the Triton router table.



    Results were perfect - depth width and bang on the centre line - no damage or safety concerns. Just great.

    Thanks to all who made suggestions!

    Will
