    Hi jim,
    That looks like a great little box , and a great solution
    to the problem, I have just made a couple of boxes
    just like that but without the threads , I will take you
    up on the challenge , maybe this time next year !,
    I only hope It would be half as good as yours
    Thanks
    Cheers smiife

    Default chasing again !!!

    Hi guys,
    Spent a couple of hours playing around with threads
    again on sunday , and finally got to join 2 pieces of scraps
    together with threads that actually work
    I was as excited as a pig in poop!
    now i wonder if i can repeat the process or was it just a fluke
    Oh well i had to take a photo or two just to show off!

    Good job Smiife, good feeling isn't it? Suggestion.... cut the male thread first, then cut off the first three threads until the marks just disappear. That will give you the inside diameter for the spigot for the female thread.
    I still think you should just chase threads without trying to make boxes, for a while any way. Tends to be a bit frustrating when the threads don't match, or the male thread is a bit small. . Probably a good idea to have another look at the Alan Batty video.

    Hi jim,
    Thanks for the tips,, I am definitely not ready yet to
    mass produce boxes , and will keep practicing with
    different timbers and use up a few more scraps
    Thanks for the advice on taking a few threads off
    for sizing too, never thought of that
    I am having trouble holding the arm rest tool and
    trying to hold the female threader and concentrate
    on what I am actually doing , any tips....?
    I seem to end up with a back ache after awhile?
    Cheers smiife

    Hi Smiifie, You probably have already done this, but, make sure there are no nicks on the top of the tool rest or the back of the arm rest, most important. I will even buff them on a buffing wheel. That makes them nice and smooth and also warms them up. Gets down to 23c here sometimes during the day. . Put your left hand under the tool rest with the thumb gently on top of the arm rest. The left hand fingers should reach the arm rest from underneath. Move the arm rest together with the female thread chaser.
    For practice pieces, turn a 50mm blank round and bore a 25mm hole through it. This will give plenty of room to work without the problem of "bottoming out", and enough wood to allow you to turn the thread off and go again.

    If you are getting a sore back, sounds like your lathe is too low?

    How long is the handle on the arm rest? Mine is 300mm long and fits comfortably under my left arm. The big advantage of it is that there is good access to the job and visibility. Seems like you have the tenacity to succeed. As mentioned before, it took me about 30 minutes to unceremonously and carelessly place the tools in the corner of the shed. Keep at it you will succeed.

    Hi jim,
    I will have a look at the toolrest and "warm it up ", only -2º
    this morning, I feel I am becoming a " pita" with all my questions
    but I really appreciate your help and thank you for it ,
    The lathe Is at bent elbow height at the spindle centre
    The whole tool measures 600mm , and the handle is 380mm
    I don, t think the tool Is the problem i think it, s the operator
    that needs adjusting , thanks again for your tips
    Cheers smiife

    Check to see if your tools or rest have become magnetized as well. ;-)

    I remember being in Armidale in July on our honey moon. It was so cold we bought and wore thongs so our feet would not stick to the floors in the showers. You are on your own baby.
    I do not consider you or your questions are a "pita", I think there might be a few people on the sidelines listening as well.... . I am only to willing to help, if I can.

    Yeah, I'm sitting on the sidelines enjoying the action. Dabbled in thread chasing ages ago, will have another go when time and patience permit.

    The types of wood have quite a bearing on results, and believe Catoneaster, Rhododendrum, coachwood, Magnolia, and possibly Teak are worth trying, amongst others mentioned above.

    Perseverance, persistance and patience and the odd profanity will help in your journey.
    Good luck with it.

    Hi alan, there has certainly been a bit of cussing and swearing,
    I think It always helps

    Jim, what thread tpi is that? What brand tool were you using, or for that matter, who makes the best tool in your opinion?

    Default still chasing !!

    Hi guys,
    Spent most of the weekend , practicing, practicing and
    more practicing, trying different timbers and different
    ways to run a thread , finally came up with one that
    kinder worked, not 100% happy with the result but
    did get a buzz when the threads actually worked.
    Not sure what the timber was but didn, t take a thread
    so decided to use some ebony inserts for the thread and it
    seemed to work ok.included some photos of the weekends
    efforts and the final box , it, s been a very big learning
    curve , but still a long way to go
    any comments and advice welcome

    Excellent, well done. Two things to keep in mind,
    1, give the tools a quick touch up before every thread. Look closely at the top of the chaser and you may notice the points on the chaser are looking slightly down on the top. They are then not sharp.
    2, don't be tempted to slow the lathe down too much. The Woodfast midi that I often has a bottom speed of about 350rpm. I have found that to be a good speed. The problem here is, with los speeds the thread is quite to establish a "kink" in the thread, often refered to as a drunken thread.
    Don't put too much on making a box yet. Concentrate on cutting good threads. I learned this from experience.

    Thanks jim,
    The low speed on my woodfast on pulley4 Is 290rpm,
    so maybe alittle too slow, I did notice the thread goes a bit
    out of wack about half way?
    I have noticed on the u-tube they all use box wood or similar
    Is that the same as our box gum trees?
    Cheers smiife

    in this case,,

    Smiife, not sure what timbers you have access to. I have chased threads on citrus fruit trees, maybe you could try some of the stone fruit woods. Can't vouch for them as I don't have access to those up here.

    Jim
    Jim, are any Eucalypt woods better than others or are they all the same? Raffan recommends boxwood, African Blackwood, lignum vitae or gidgee. For Cocobolo and ebony he suggests cyanoacrylate application to prevent chipping. He has nothing to say about Eucalypts though.
