    I have the same lathe . imperial , i think you can cut virtually all the metric pitches you will need with the set up you have , the gears are a fortune !! been looking for months on ebay, too tight to pay the prices they want , £175 for the compound gear is about avridge !
    i would get in loads of practice cutting threads , before you attempt to make anything , also remember the thread dial indicator is no good with the metric gears on , you need to keep the half nuts engaged all the time when taking cuts .
    mr pete and this old tony have some great thread cutting vids, good luck !

      Thank you Paul. My lathe is more than good enough for what I need I think and is getting put to work regularly. It's cool that once you make something, you instantly think "if I can make that, I could probably make this other thing as well...?!!" Hehehe... Great little lathe in my book.

    A large printed template fixed to the gear blank and a pointer would be accurate enough for low speed gears btw, keyway broaching could be done on the lathe so a gear tooth cutter for the mill is the only real outlay

    Just a wee tip, try and not use the halfnuts for normal turning ,always use the clutch ,save your "nuts" 🤣 for threading .The guys you mention on the vlog regarding gears always charge way too much ,personally I will not be ripped off . Look on ebay there are always sets of gears or single gears for sale at proper affordable prices . I know I'm a bit to the party in the comments ....

    • @QuickBikes

      A very good tip matey... over time I've come to do all my roughing out passes by hand and then use the clutch for the final pass to get a nice finish. I'm learning as I go, but that's a good tip, thanks for chipping in matey 👍

    Hey there, how did you go with your gears? I have made a lot on my wee AUD boxford out of tufnol, cast iron and steel for smaller gears. Made a fly cutter set up that mounts where my tool post sits and index from the back of my spindle. Believe it or not I use an electric hand drill for my fly cutter drive and a Kenwood cake mixer for cutting steel gears. Works awesome for me.👍

    • @QuickBikes
      @QuickBikes  3 ปีที่แล้ว +1

      See, I love that... it seems you can do all sorts once you get a lathe, all you need is a bit of imagination. I've been told you can use them as a tube notcher as well.... put the hole cutter in the chuck, a V clamp in the tool holder to hold the tube, set the angle you want the notch cut on the compound and feed the saddle in to make the cut. Haven't heard of a cake mixer being used before though 🤣😂😅

    Have a look into phenolic for homemade gears mate, no reason for hardened steel as you said. Even cast iron would be a hell of a lot easier to work with

    @markrainford1219 3 ปีที่แล้ว

    You only need one or two more gears to cut virtually every metric thread with the setup you have already got. Delrin gears on fleabay are only a tenner or so each and perfectly adequate. I've been using a set for two or three years now. You definitely don't need a 72/18, not certain but I think that's the conversion gear for the variable speed lathe. Sure you've worked this out yourself by now though.

    • @QuickBikes
      @QuickBikes  3 ปีที่แล้ว

      Yup, just waiting on Jamie to do his wiring thing and we should be in. Basically I need to be able to reverse it without disengaging the gearbox. Once that's done, I'm sorted 👍

    0.2 to 6 covers everything you'll need for metric threading unless you're doing full-on "art" stuff like that 10 start bidirectional bolt that crazy russian put on youtube recently. I've never seen anything bigger than a 6mm thread used anywhere, and I've done a lot of *big* stuff. Anything over 4mm is pretty much exclusively stuff like leadscrews.
    Does the boxford not have a setting for auto-feeds that doesn't use the leadscrew directly, instead driving off the groove in the leadscrew? That's the normal setup, and it doesn't wear out your split nuts, andit's normally internally geared on a feed per revolution basis that's way lower than the leadscrew gives you (it's usually around 4:1).
    I'm just jealous that your lathe does threading, though. Mine don't :)
    As for "don't have a stud"... You have a lathe and a mill.

    • @QuickBikes
      @QuickBikes  3 ปีที่แล้ว

      Unfortunately the power feed is thr lead screw, not a separate shaft, but I'm not complaining 🤣😂
      The other gears I ordered turned up today so I can do all thr usual.threads now I think, but I'll have to check again to be sure 🤣😂

    • @wibblywobblyidiotvision
      @wibblywobblyidiotvision 3 ปีที่แล้ว +1

      @@QuickBikes Yeah, it's through the leadscrew rather than having a separate feed shaft, pretty common setup that, but it should be driven by the groove in the leadscrew rather than the threads themselves. You use the feed change lever and feed clutch control that are found between the handwheel and the half nut lever.
      IIRC they interlock with the half nut lever, so you can't engage both at the same time, but, from memory (it's been a while since I've played with a boxford):
      - half nuts disengaged
      - move the feed select lever up for cross feed, down for saddle feed, in the middle to turn it off entirely and either hand feed or use the half uts.
      - screw in the clutch knob until it "bites".
      - robert is your mother's brother.
      Can't remember if there's a quick disengage. Like I said, it's been a while.
      The difference in doing your power feed this way is that you don't have to engage the half nuts (which *do* wear out, and *will* cost you a new arsehole to replace), unless you're actually cutting threads, you get a finer feed and thus better finish, and you should be able to power feed the cross slide as well as the saddle (a low speed power feed cross slide can be really good for cutting off. Or breaking cutoff tools :).
      Stay safe.

    • @QuickBikes
      @QuickBikes  3 ปีที่แล้ว

      Sorry, I misunderstood you. Yes, you can drive the saddle and.the cross slide via the clutch, but as you say there's no quick release for it, you have to.turn thr knob which is rotating.with the clutch assembly. I've never used it for that reason but maybe I should have a play and see how I get on with it 😁👍

    Perhaps check this out: www.herosteamengine.com/RideTheGearTrain/ - You just programme in the change gears you have and what you want to do and it spits out all the options. As you have the gearbox, you'll find that you can actually cut a range of threads with only a few change gears.

      @@QuickBikes No worries. I have a Model A (even older than yours) and find the resource very helpful. The manuals generally give one way of doing things but the software gives options - often you can achieve a lot just by changing the settings on the gearbox whereas the charts might have you getting the spanners out!

  • @wibblywobblyidiotvision
    @wibblywobblyidiotvision 3 ปีที่แล้ว +1

    Making your own gears isn't that hard once you have a way of indexing. *You do not need* a set of module gear cutters (which are stupidly expensive) to do it either. Actually, thinking about it, they're probably "diametric pitch" cutters, which are even more fucking stupidly expensive, and depending on the age of the machine you'll need to worry about what pressure angle they have, too.
    The easy and cheap way to do this is to make a fly cutter, and grind a form tool for cutting the teeth. It's slower than cutting with a dedicate cutter, but frankly who cares if you're not making enormous series of gears anyway?
    You'll also find that you can get away with using softer material for the gears. Sure, cast iron gears are stronger, but aluminium is fine for occasional use, and so is plastic (heresy)
