In this video I address the proper gear setup for threading imperial and metric threads on the Jet 1340 or the Grizzly G4016 metal cutting lathe. If you're having problems with getting your threading passes to go on top of one another this could be your problem.

I think it's called gunsmith lathe. Not for threading I guess. 1700 on Facebook market. Looks very attractive but I guess it's not what you'd expect.

This one wasn't sold as one per say. It does thread, this one has an imperial lead screw, so it threads imperial threads by closing and opening the half nut. But if you thread metric, you must leave the half nut closed during the entire threading operation. In this video the whole problem was that I forgot that I had cut metric threads and forgot to change the gear back.

Thanks for the great information, I had that same problem with my Jet 13x40 lathe but I thought it was just a bunch of chips jammed up in my 1/2 nut but I was wrong. After I cleaned them out the problem was still there, so that's what lead me to see your video. Then I was able to fix the problem. I had a question about your three phase motor change over. About how much quieter did it run in a percentage? I ask because mine seems to be loud but I think its because its in a supper small space which makes it seem louder than what it really is. Also I made a video about my jet lathe which might interest you it called Jet Lathe Automatic Threading Stop. Thanks again for the great video. Gary

Hi Gary, yes, I just watched your video about a week ago. Nice job. The 3-phase motor makes a lot of difference, you have infinite speed adjustment using a VFD of course, the noise level on mine is half what it was. It's like a whole new machine. Thanks for tuning in.

Interesting video Dale, What a Beautiful Machine you have there ! What a Head Scratcher, But you sussed it out in the end, All the bikes you work on are Metric Threads I would have thought you would be cutting more Metric Threads than Imperial, and most of your measurements in your videos I notice you usually measure in Imperial, I often wonder how clever people are, the knowledge to design and build a machine so precise, and probably built long before computers/Cad came on the scene, quite amazing really. Well at least your keeping your brain sharp !! Well Done Buddy !! All the best, Malc U.K.

Oh man, Malc, getting old is for the birds. This thing was driving me nuts. Over a half a day wasted because I didn't change the gear back. One thing for sure...I will probably remember this. I am also writing on a piece of tape at the gear access what gear I have engaged. Its old technology for sure but I really do enjoy running it. It really does good work for a Chinese machine. Yes sir, I think keeping busy is the ticket to keeping the mind going. Guess I better get busy. Mine needs a little help. Thanks, Malc, and happy new year to ya.

Glad you worked it out Dale. I'm surprised you don't turn metric threads very often, with your work on Japanese bikes. I use paper slips to set my change gear backlash, yes, I'm that guy. Have a great new year my friend. Best wishes, Dean.
@montana2strokeracer
@montana2strokeracer Год назад
Hi Dean, you know I just don't turn many at all, just large ones like this, I do what most people do. Use a tap and die set. Thats alright if you use the paper trick Dean, I'm still your buddy.

@@montana2strokeracer thanks, I was worried about the paper thing. Taps and dies do make sense for most stuff. I suppose it's the odd stuff like pullers that require the lathe.

Good video. I am looking at a Enco 13x40 that looks just like this. I will check your videos out.
@montana2strokeracer
@montana2strokeracer 8 месяцев назад
Yes these lathes were labeled by many vendors. Jet, Enco, Grizzley just to list a few. 13 x 40 is the size. I converted mine to 220 3 Phase, it's like a brand-new machine. So much quieter and infinitely adjustable.
@chuckgilbert2035
@chuckgilbert2035 8 месяцев назад
what did you do to turn it into 3 phase?@@montana2strokeracer
@montana2strokeracer
@montana2strokeracer 8 месяцев назад
Hey Chuck, all I did was find a three-phase motor, in this case I got a 2hp unit, the original is a 1 hp. Then I set it up to run on a VFD that turns 220 single phase into 220 three phase. The motor was not a bolt on unit, had to make a bracket but it was really worth it in my opinion.
@chuckgilbert2035
@chuckgilbert2035 8 месяцев назад
Well I went out to buy a lathe, doing the trailer hook up to haul it on and the guy let know someone beat me to it. Sent a message to another guy with a chucker lathe, drove 100 miles to find out it was 3 phase. Bought it anyway thinking I could use a VFD. Get it home then doing more research found out that you have to have a VFD for each motor (this machine has 4) So now doing research for a Rotary Phase Convertor. Hardinge HC High precision lathe. Love this stuff.@@montana2strokeracer

You always provide worthwhile knowledge and know how with every video. Ran to the garage after listening to you're video and found out that my lathe is similar to your's (12x36 shun shin) with same gearing set-up. Mine is set-up on the 40-127 with the lower gear being a 32 t, found a 40 t is in the toolbox for the lathe. I use the lathe more for turning than threading and when threading I try to use dies. You're video made me realise that this set-up is not good and will relocate the 32 t gear with the 120 so I can some specific metric thread. Thank you Sir and boy am I happy you touch on this subject. Happy new year and keep them coming.

Wow that's great, I really didn't know if I should do a video on me forgetting to change my gear back, but I was certainly stumped. Was sure glad to figure it out. I only cut threads a couple times a year and just don't remember the last one I did. Sure, glad it helped someone, because I sure couldn't find anything on it. Sometimes you just have to put your head down and charge ahead. Thanks for hanging out in the shop with me.

I know Danny, if you have the manual for it, it is absolutely very little help. I don't cut metric very often and I always have to re school myself every time, I made a cheat sheet. Now it's easy.

That was a very interesting film. I had a similar problem recently, though not with repeat pick up, but machining the wrong pitch. I had installed a gear with slightly lower tooth count than the one I needed. I've used a Jet lathe, it was on a ship I worked on. It was an exact copy of a British lathe, a Colchester Student in fact. It was made in Taiwan I believe. It performed very nicely.

@montana2strokeracer Год назад
Well Carl, it's nice to know lathe gremlins are everywhere not just here in Montana. I believe Dean had one he told me about also. I have had this Jet lathe for about 25 years, and it really is a very good lathe in my opinion.

I had the same lathe , was a yangzhou brand, jet, grizzly, enco, and there were several other no name brands that made the identical machine, grizzly actually labeled there's a 13 1/2 x 40 , my yangzhou would turn just a little over 13.5 also, actually was a good machine , but keeping up with the change gears was a pain , I thread all the time and same thing with me you forgot to swap that bottom gear ....... WOOPS

@RonnieRose-f5x
@RonnieRose-f5x 6 месяцев назад
I seen the gear off the start of the video, and got a bit of a chuckle because I had done the same thing a time or two going back and forth between metric and standard threading.... But I like the fact that you put it out there to show mistakes happen, here's what to look for, and there is no perfect in the real world and didn't edit it out. I like RU-vidrs that don't care to share honestly, not try to make everything picture perfect, keep up the good work

@montana2strokeracer
@montana2strokeracer 6 месяцев назад
I agree, it has changed the whole operation for the better. I put a 2hp on mine, but I have a 3 hp motor also, I bought a lot of 3 phase motors when folks were giving them away. Now with the VFD's the prices have gone through the roof.

@montana2strokeracer 6 месяцев назад
That is a great price, those things are heavy mothers. I have used them in all kinds of equipment, the last one I used on my bead roller, the thing that's great is you can turn it way slow, and they still have the torque needed for the job.

Yes there heavy, I used to work at a plastic extrusion company in there maintenance department, there antiquated equipment was getting so out of date there DC drives and motors on there extruders was getting where parts weren't available so we had to convert them all to AC and vfd , the biggest motor they had was 150hp and yeah I wouldn't want that to drop on my foot lol

When I was working in Dallas Texas some 35 years ago I purchased the Enco model 110-1340 bench lathe. It was the same as your jet but much less refined, Manuals were printed on comic book paper. I drug that lathe with me to Las Vegas then on to retirement 40 Miles north of Seattle. As crude as the lathe is it has always been reliable and spot-on. It has been sold worldwide by Jet, MSC, Bermingham, Sharp and was sold by Grizzly as the G4016 - 13-1/2" x 40". I buy parts for it from Grizzly and have printed their manuals from their online catalog.

Hi John, well how about that, 35 years ago I was working in Ft Worth. I really enjoy my lathe, the best thing I ever did was change it to 3 phase power and put a VFD on it. Much quieter, smoother, and infinitely controllable. Yes, I have bought parts for mine from Grizzly also. The manual is still a lot to be desired.

Dale: I spent my first 19 years in Portland OR, I thought I had seen rain. Not so, saw 12" in an hour in Lewisville TX. Nice people, bad weather. If I wouldn't have spent all my energy moving around the country my lathe would have been 3 phase also. Following the evolution of the IT175 I think a 200 cc Yamaha engine in a YZ125 frame would make a great cow trailer.
