    I have this same lathe, but mine had the Harbor Freight name on it, and although it’s 20 years old, I just acquired it still in the box! Certain parts of mine were packed with that sand/grinding dust crap while others were fairly clean. I did a total disassembly and cleanup/tweaking to be safe. The cast iron lug that rides under the ways to lock down the tailstock was an incredibly poorly cast and machined piece that broke in two after several uses. I repaired it with nickel electrode, then it broke elsewhere! Grizzly’s G4000 is the same machine, so I searched their website and found the p/n and photo. That pic showed another hideously produced part, but I ordered one anyhow, and also made one on the mill. What I received was an absolutely perfect part, so well done that I didn’t even use the one I made! There is a definite difference in these similar machines depending on the company selling them! Some evidently don’t hold the Chinese producers to any kind of quality standard! Great fix Matty!

    No problem with the intro, just worried your tea may go cold!.
    Yes, production shortcuts, and zero quantity control, makes for a good profit with customers unable to return items, or be corrected. Getting the casting sand out is a pain, but that amount is unbelievable. Anyway, nice job for remanufacturing. Alkyd red oxide paint does a fairly good job on sealing castings, and resistant to mineral oils, the Glyptal is a full gloss enamel paint, and helps oil flow where necessary, but the Red Oxide Alkyd is plenty good enough for standard machines. Does anyone else have experience in using this?
    Thanks for sharing Matty.
    Best regards from the UK. John.

    • @MattysWorkshop
      @MattysWorkshop  4 года назад

      Gday John, the headstock did have paint in there but not enough I’d say to glue the sand to the sides, I’m going to take the apron off again and paint the back, I’m pretty confident I got 99% of the crap off, I didn’t paint it straight away because I was to excited to see if it was going to work, it’s easy to remove so it won’t be hard to paint.....

    • @howardosborne8647
      @howardosborne8647 4 года назад

      No experience with the Glyptal but I always pressure wash and abrade the insides of iron castings and then apply 2 coats of 2 pack etch primer. That seals all surfaces and ensures no further grit/sand gets free.

    • @bostedtap8399
      @bostedtap8399 4 года назад

      @@howardosborne8647 2 pack paint is difficult to beat, guessing historically that most paints were linseed oil based (excluding Cellulose, though they is obviously others), there were very few that were oil resistant, even less fuel resistant. I had a Royal Enfield engine as a youngster, only the bottom half, and it was painted a light grey/cream colour and found out it was to improve oil flow.

    good job Matty. I enjoyed watching it. If I remember correctly there is a paint called Glyptol that is used to seal cast iron inside engines and gear boxes. The better lathes will have it inside the gear boxes. Thanks for sharing.

    Cincinatti to the rescue!
    Dual feed, leadscrew like the Hercus Lathe.
    Lubrication is an issue on your lathe lead, feedshaft, I wonder how Delrin Bushes would perform.
    Can't remember how Hercus is set up.
    My 12" lathe has separate feed shaft from the leadscrew and also runs directly in the casting but has an oil bath that I must regularly top up.
    I think the manufacturer should have installed bushes so they can be replaced as you have done, the right way.
    Good job Matty.

    Worked out real nice there, Matty. If the boring job hadn't turned out good you still had another couple of alternative options by milling out the 2 iron lugs completely and screw fixing a couple of new lugs made from steel with bronze bushings in the bores. Always more than one way to skin the proverbial cat.

    G'Day Matty, rock solid methodology in that repair and it worked out beautifully. Yes, Chinese lathes from Hare and Forbes. I bought a small lathe and converted to a CNC, and the bearings seized up. The reason was all the sand in the Headstock. There was even a 4" nail embedded in the casting used to hold the core together and it was rubbing on the spindle. All they had done was spray paint over the sand to try and hold it in. I had Hare and Forbes purchase new Timken Bearings for me and I also had the Hearstock sand blasted at their cost to remove any other muck. You won't have those sorts of issues with your new Taiwanese Lathe, they are first class machines.

      Gday Cam, it all worked out well in the end but I did do a lot of time wasting triple checking myself😂, I only had one crack at this repair so I had to get it right, Hare and Forbes supplied the bearings for the head stock and I think the may have been Timkin bearings, it’s funny you say about the nail, a bloke in town here brought the same lathe as mine and had the same issues with the headstock, he also got a nail out of his, I thought he was pulling my leg until he showed me a photo, I think the Chinese factory’s need to be controlled a little better and improve the quality, cheers Matty

( No Q/C G/box ) I also have the same problem with my lever going all the way on to the apron and hard to disengage it . ( But i know how to fix that Now ....Thanks ) when i brought the lathe the bloke said the lever for the half nut was seized , but in actual fact its the Half nut that has broke . so i go onto Hare & Forbes site and find the part saying its for AL50A 1.5 pitch and think great I'll just change it , .... woope doo ! BUT what they don't tell you that there's 2 different Threads on the lead screw ,1.5 and 2.0 , And the 2.0 is unavailable , and of course they want a restock fee if i return it . SO , here's my question ! Can I just simply change the lead screw from the 2.0 pitch one that's on it , To the 1.5 one to match this new half nut ? .... Of will it mess all the gears at the motor end ? ....Cheers ... Johnny.
