    Amazing series Jon, im in the middle of rebuilding my RF45 clone gearbox and i can confidently state this video series is THE master reference on the Internet for this process. No way i would have got the shaft order correct without the hard yards you did!

      Also if u get more noise developing check out the keyway on the sliding gear shaft closest to motor shaft. Its a common issue that the 5x50 keyway gets flogged out (mine was)

    Your video helped me a lot. My milling machine is the same as yours what happened when I switched the motor on and clicked the gears the motor was running but none of the gears were turning so the head wasn’t turning so I thought that the key fell out of the motor shaft but no it was still connected so then I thought that the key fell out of one of gears so I started to lift the lid to look into the gear box but it was too much for me it was like opening a can of worms. The bloke who sold the machine to me said it was still under warranty it is only 6 months old so I boxed it up and sent it back to him. So he is sending me a new Precision Matthew’s PM 728 Mill which should arrive in a couple of days. Thank you for sharing with us your videos it was very helpful. Cheers Doug from Australia.

      Hi Doug, thanks for the comment, it's certainly not a well designed gearbox for easy maintenance. Sounds like you did the right thing. Cheers, Jon

    It just shows what a huge difference careful assembly by skilled hands can make. Imagine the price if they came from the factory with that level of preparation. It's a good machine now John. Dean.

    • @jonsworkshop
      @jonsworkshop  4 ปีที่แล้ว

      Hi Dean, thanks for the comment. You're right, it also shows that the rest of the machining on these things is actually to a fairly decent standard, and they throw it all away at the dressing and assembly point. Certainly skilled at inserting and removing gear shafts now if nothing else (those things were in and out more times than a pensioners leg at a Hokey-Cokey convention)! Cheers, Jon

      @jonsworkshop  4 ปีที่แล้ว

      Hi Tony, thanks for the comment. Kinematic numbers are almost where I would want them to be, could always be better but I need to remember what I am playing with here, no point trying to make it into something it isn't. The lost motion check is probably one of the best indicators of spindle bearing adjustment / wear etc and is universal across all machines (horizontal spindles need a bit more care due to effects of gravity). Lol, I actually considered foil for the funnel, but in every "think through" it ended in disaster! Cheers, Jon

    Jon I've just started watching thanks to DB and ABE's pointing in your direction. I decided to watch one of more recent ones 1st then went back to the beginning so glad I have then worked my way through and will continue to do so. To see how you struggled with crap camera, sound and minimal gear but wealth or knowledge and experience behind you shows how it can be achieved by many. This series on the mill is scary for all Asian made units as 99% come out the same factories no matter the brand or country where they are sold from. I have a HM-48 and have my concerns even though this machine was a floor demo model and the people I dealt with will have done their best to make it as good as they can. Keep up the good presentations.

    Very nice walkthrough of the process. I just finished cleaning an used one. It was full of chips and grease in the wrong places. Only concern to me is the quill gear and low-high speed gear. They are way above the sight glass level. I don't know if they are lubricated by splashing, but when i opened the top, they were pretty dry....

As I have always said, to not know and get it wrong is excusable, to know and still get it wrong is criminal! On the plus side, I didn't spill or splash a drop (which I am pleased about because that gallon cost £13)!! On another plus note, my homemade midget enema kit worked really well. Cheers, Jon

    Nice one Jon, I have enjoyed this series. Good to see your mill up and running again. 👍🏻
    It is just a shame you have had to do all this to a new machine. All in all would you still recommend this make of machine to another potential buyer or knowing what you know now would you have gone for a different option yourself ?
    Am looking fwd to your next projects.
    Take care Jon 👍🏻
    Regards Tony

    • @jonsworkshop
      @jonsworkshop  4 ปีที่แล้ว +1

      Hi Tony, thanks for the comment and feedback. Its 6 of one and half a dozen of the other really, any Asian import mill would benefit from the same level of work so the brand almost becomes irrelevant (they are all pretty much the same). I look at it like this, I paid £1700 for it including the stand and delivery (Dick Turpin would be proud of that), and I have spent £100 on bearings and £6 on oil, so £1806 all up. If I bought a used Bridgeport for the same money it would be absolutely knackered and probably need another £2k spending on it to make it useable, and probably more hours of graft. I would have preferred the Bridgeport but the savings I made paid for my lathe. Its a no brainer really for a home shop, just got to be prepared to roll your sleeves up. Hope this helps answer your question. Thanks for the support. Cheers, Jon

    Is your lathe motor close to the max(2.2 kW)of the static converter?And if so is it coping well?Robert

    • @jonsworkshop
      @jonsworkshop  4 ปีที่แล้ว

      Hi Robert, thanks for the comment. I am pleased with it now and I hope that you will find it useful information. My Lathe has a 2.2kW motor so right on the limit. It copes OK but it is all a bit of a compromise. The transformer is designed for a, static load like a compressor or a generator etc, the lathe is dynamic as each cut will draw a different amount of power. I have found the best setting (number 4) and work round the compromise. It does pretty well really. You will probably need some help setting yours up for the mill as you will need to alter some settings inside the unit, let me know when you get to this point and I will give you the info I got from Power Capacitors. Cheers, Jon

    G'day Jon and greetings from Tasmania Australia, one question I have, my mill is a HM 46 very similar to yours, do you have problems shifting the levers for Hi & Lo and speed, mine are very tight and hard to move. I have subscribed to your channel kind regards John

    • @jonsworkshop
      @jonsworkshop  4 ปีที่แล้ว +1

      Hi John, thanks for the comment and subscription, much appreciated. Can't believe my humble little channel has made it that far round the world, I am honoured. In answer to your question, they were both very stiff as new, they are much better following the clean up work (but still a bit stiff). Having seen the detent arrangement on the shafts, I am confident they will slacken more with use (the spring that holds the ball bearing into the detent positions is quite strong). Hope this helps and thanks again for your support and interest. Cheers, Jon

All resellers are the same regardless of name. There is a reason they are cheap and this is it.

      Hi Greg, thanks for the comment. If I was in the market for another Chinese machine, Cormak are as good as any of the other importers. You need to be prepared that you are buying a kit of parts (from any of them) that will need significant work to make it half decent. They get the first 80% of the manufacture done not too bad, and then throw it all away on the last 20 through lack of cleaning, de-burring, and fitting crap bearings, all the Chinese import stuff is the same.

    • @jonsworkshop
      @jonsworkshop  3 ปีที่แล้ว +1

      Hi woo zhi, thanks for the comment. It is exactly the same machine, just re-branded. My personal opinion is that you may struggle with a big fly cutter, mine struggles with a small one! This is due to the gears in the head being plain spur gears with lots of backlash (clearance) meaning with an interrupted cut, the head is very noisy and this translates through the spindle affecting surface finish. I think you would be better with a direct drive model for your application. Hope this helps. Cheers, Jon

    • @woozhi9218
      @woozhi9218 3 ปีที่แล้ว +1

      @@jonsworkshop Thank you for the reply and your experience with this machine .Would it be okay if i run the spindle slow and with a low gear that is torqy or just fix the backlash,but i would be running it slow anyway unless its a finishing or i have to get it done quick?

    • @jonsworkshop
      @jonsworkshop  3 ปีที่แล้ว +1

      Hi woo zhi, running slow will help. You won't be able to remove the clearance between the gears as there is no adjustment in the head. Success will really depend on the material type you plan to cut and the depth of cut, very light skims (shallow cuts, 0.2mm) on soft materials will be OK probably. Don't expect to be taking 1mm depth of cut on steel with a big fly cutter, it won't be a good result. Hope this helps. Cheers, Jon

      Hi Steve, thanks for the comment. Good question. I am sure normal 10W 40 would be OK, but the gallon of ISO 32 cost £13 and that will do two fills so will probably last a couple of years or so. After all the effort and hard work, saving 3 or 4 quid by not putting the recommended grade oil in just seems a bit foolish (and that is coming from someone who is tighter than 2 coats of paint.... Lol). Cheers, Jon
