Hello, I would like to ask your help on how to set up for threading
Mainly 5/16 18 for ferrule tenon and 3/8 10 for shaft thread and joint....too many knobs ... I never done this before... this is my lathe set up... thanks in advance. ...

Many here could give detailed instructions - but IMHO - you would be much better
served by searching Youtube.

With that said - there should be a threading chart on the headstock that tells which
lever to put where to get the TPI desired.

From your setup, you better not thread IN. :eek:
Make sure your chuck will be spinning away from you.
Your on lever would be UP for counter clockwise spinning.

As Dale mentioned, you need to check the chart for the TPI combo.
You will need to set the RPM to the slowest setting .
I don't know if you need to change the belt location. I do on my lathe even though it's a gear head . You will also need to make sure they installed the Imperial gears. Not metric.

The thread engage lever is the horizontal one on the saddle ( rightmost ).
Down engages is and up disengages it. Have your hand there ALL THE TIME after you engage it .

Find a youtube video as Dale suggested . This stuff is dangerous.

Well, I think I see your first problem. Lathes are meant to run horizontally, not vertically.
Lay that puppy on the floor, feet down.
Second is, you shouldn't touch the 'start' button until you've taken classes.
If not, you're about to make a HUGE mistake, AGAIN. There are cleaner ways to kill yourself.
I'd say that buying, or even thinking of operating a lathe that you have no clue
of how to run is a disaster in the making. Son, I'm going to put it to you bluntly: YOU ARE DELUSIONAL.
 
I have no idea on your lathe skills at all.
My suggestion is to find a night school class and learn the basics of turning.
There are just too many things to put in a post to threading on lathes.
You need to check that the gears in the drive side are correct for what you want to do.
You need to verify that the pitch it is producing is the pitch you want.
Ensure that you engage the correct lever for longitudinal travel,not the cross travel etc.
There are youtube videos galore, but there is not substitute for a teacher or someone to show you 1st hand. Once you get familiar with various aspects of turning, whether it be a Grizzly or a Hardinge, it won't matter, as you will then have the skills to figure it out.
Long skinny tools on routers can be a challenge in itself and dangerous as well.
Be safe, be very safe. You just can not think of safety too much when operating shop machine tools of all kinds.
There is a big difference to thread cutting on a single phase lathe to 3 phase as well.

Reading the manual on your new $ 4000 lathe should be the first thing you do...
There are atleast a hundred videos on youtube on threading and how to operate a lathe.
But threading is quite easy, select the right gears for the desired TPI.
If you're treading in ( from right to left) set your DRO at 0 where you want the threading to stop.
Move your threading tool so it just touches the rod you want to thread and set your thread dial to 0 on your cross slide.
Back of an inch or so from the rod you want to thread. Start the lathe and engage your feed while watching what number comes up on your thread dial indicator.
When you reach 0 on yor DRO disengage, turn lathe off, back off the cross slide. Go back to start position, move the cross slide in a few thou and start over, be sure to engage the carriage and the same count on the dial indicator, so the threads match up.

Best thing you can do is start by removing the DRO, I'll tell you why in a minute.

1980, I was 15, I learned many things on a full size metal lathe, I made many threads in hard steal, inside threads and outside threads, I still have the vice that I made then, it works great to this day. I even learned how to make square threads, in order to do that, you had to learn how to make your own inside thread cutting tool. Don't let anyone tell you that School is not cool.

Oh yeah, I'll pm you my address, when you get the DRO off, you can send it to me, Thanks, Dave.
 
Take a class, watch some youtube video's on the subject and also buy a good used copy of a machinist hand book. But if I were you DONOT just try and operate that lathe without any prior experience or lathe use knowledge. Be safe out there.
 
Your set up looks ok.

One thing I like to do when cutting threads in wood with a thread mill is to put the head stock in high gear or in between gears (most lathes will still turn the lead screw like this) then I spin the chuck or spindle by hand. This gives you more control to stop it before it runs into a shoulder, and on my lathe the lowest speed is still kind of fast to cut threads in one pass.

Just remember safety first and go slow when you are learning

This one you can release the gears and crank i manually.
Great workout. Lol

Pamp. spend a semester at your local college. Machining 101 is a must take.

Take a class or hire a machinist to work with you until you are familiar with your lathe. Don't risk your body parts without getting some needed education. The You Tube videos are good but I still think you would profit from "hands-on" help.

Best of Luck!

Just based on the pics,what concerns me most here is his thread mill.

That router better be PERFECT or that cutter is coming apart. Tommy D.

Grizzly lathe help how to operate...

If he has the router spinning true enough for it to do the job without becoming a carbide missile,then I'm all for it and applaud him.

Just seems like the kind of thing that might go horribly wrong before he even touches off. Tommy D.

Been using Makita grinder and router to thread for almost 12 years now.
Tried a cnc spindle too but the slow start turned me off.
Kress router works well too. So does Bosch Colt.

And here I was waiting for Joseph to suggest the same, as he usually does.

Nice set up that you have just the same. In this case, if you have not any practical
use on a bigger lathe as what you have, Community College, Google and Utube are you bestest Friends at the moment.
