    Yes, noted how when I got it, the 20 tooth gear was used as a spacer in the original setup when the 50 tooth gear was the driver but when set up for slowest feeds using the 20 tooth gear as a driver the only remaining spare gear, 40 tooth is too big to clear the 100 tooth gear as a spacer. At least the set is complete with the 20-40-50-80-100 teeth change gears so if a spacer is all that's missing I don't think I've done too bad. Relatively easily rectified.

    Hi Mike,

    Thanks for the photos posted last month. Must admit I hadn't looked at forum for a few weeks.
    I'd say the ones on the right are the Qualos Juniors. Small world department: my neighbor 3 doors up has one of them!

    Have been tidying mine up and just waiting for rain to stop to finish painting the legs. Once that's done I will re-erect it. They are the only things I intend to paint as there was a bit of rust on them. I have painted the underside of the chip tray for the same reason, the lathe itself is being kept in its "working attire". It's looking pretty good just cleaned up. Sourcing a new Aluminum tailstock hand-wheel with a handle that looks a bit more like the original instead of the "pulley" that was used on it as a hand-wheel. Will still keep a lookout at Bendigo Swap next month just the same for an original.

    Cheers,

    Jacques

    Default gear setting

    Hi Jacqualos,
    A method I have used for years to set the mesh of the change gears is to insert a piece of paper between the gears when pushing them into mesh. After the stud is tight roll the spindle by hand till the paper is ejected and voila - clearance.
    Enjoy you lathe, Borriss

    Default Checking change gear clearance

    Hi Boriss,

    Thanks for that handy hint on setting the clearance on the change gears using a piece of paper.
    Sounds good to me!

    It's a bit like some of the old auto mechanics using a matchbook flap to set the points on a car. Worked well for thousands of cars too. Sometimes the simplest is the best.

    Cheers,

    Jacques

    I have the same model Qualos as your lathe Jacqualos. Can you tell me how many and numbers of teeth on the change gears you have?
    Also, did your lathe have its travelling steady with it?
    I have found that chainsaw bar oil is also more than adequate for oiling the beds ways and all the oiling points around the lathe.

    Good Day,

    I have the complete set which consists of 5 gears: 20, 40, 50, 80, 100 teeth.

    Have included a photo of the two point traveling steady on the saddle- took "artistic license" and did not bolt it down for photo. Still haven't looked through all the stuff in the box of bits and pieces that came with it. No doubt the bolts are there. Easy fix if they are not anyway.

    I was very lucky as the lathe was very complete for something built over 60 years ago. Even have the original Operators Handbook which our friend found in her late husband's bookcase and he was the second or third owner of it. It was leveled on 12th June 1951 as written in the notes so I have some idea of its age.

    Speaking of which, I had previously obtained a pdf file of the manual from Mitutoyo Qualos here in Melbourne and they have kindly given me permission to post it here if I wish. Also have some pdf file period sales brochures they also sent me.

    Let me know if you are interested, and if the forum allows files these large to be posted, I will do so. I don't think they are excessively large but must investigate what is maximum allowable.

    Cheers,

    Jacques

    A year or so back I was visiting a local oil distributor to pick up some bulk chainsaw bar and chain oil and the distributor asked me how tacky I would like the oil because he could make it as tacky as I liked. I was very impressed at how stringy he could make the oil. When I asked him what was in the tackifier he gave me a copy of the MSDS sheet and I do not recall it containing anything common like PVA. I just did a quick check of some MSDS for Chainsaw bar oil tackifiers and they show it contains polyisobutylene and ethylene-propyline copolymers, there's no woodworkers PVA in it or VV. Maybe it was once made like that but not these days.

    Hi Mike,

    No argument there! If Melbourne weather would dry out I would have had it up an running by now. I'm afraid the truck restorer comes out a bit with me on this project and I want it at least a bit tidy before I start. All I need is two good days to finish off painting the legs and I can re-erect it.

    Is it as addictive as restoring a Ford "Blitz"? If so, I am in trouble big time!

    Cheers,

    Jacques

    Default Qualos lathe on Gumtree

    No doubt many people may have seen this one but Gumtree has a 5 1/4" Qualos lathe for sale at Circular head.

    Still waiting for dry weather to finish painting the stands. Found when I stripped them they were full of a lot of casting flaws and looks like they were factory filled with a type of early spray putty on the visible sides anyway. Wish now I hadn't done it and just thrown another coat of paint over it but we are all wise in hindsight. So a bit of back filling and sanding is now required and the 2 day job has blown out to a quite a few days weather notwithstanding.

    Anyway, sorting out the big box of bit that came with it while I wait, and making a lookfor list for Bendigo.

    Have a question: Just curious does anyone recognize the trade mark on the tool holders that came with it? See attached photo. Obviously Australian made so would think they are the same vintage as the lathe.

    Cheers,

    Tool holder is a Lock. The one I have has this symbol on one side with a couple of other letters and Aust. Other side has LOCK.

    Default Qualos lathe on Ebay

    Hi Mike,

    No, missed that one even though I have "Qualos" in my saved searches. It has an aftermarket tailstock handwheel also as mine does now. Replaced my "agricultural" pulley of a handwheel last week. They must be a routine casualty.

    Thanks also Phil, for that info re Lock Brand. Could not find a lot of info on the company on the net other than it was Lock Tools Victoria. Since my earlier post I found some smaller tool holders in the box embossed with the word "Lock" but I never made the connection. Guess they are long gone like most manufacturers in this state.

    Cheers,

    Jacques
