Hunting for a small lathe [9x26]

Huh?????

Randy Replogle

Is the ability to turn and thread in a direction AWAY from the headstock worth a few extra bucks?

Would that ability ever be nice to have? > >

Fools rush in where angels fear to tread. I love the uncertain...

Consider working on a cylindrical workpiece in the chuck. You want to thread it away from the chuck so you can form the shoulder and threads without feeding into the chuck.

As to the toolholder, are you concerned about the toolholder being on the downfeed side? Otherwise, the turning forces are pushing the toolholder out of the toolpost? Mary, mother of multiple hold down bolts, hear my plea...

Oh, heck, I want to turn threads us> Can you explain how you intend to do that while not unscrewing your

I don't know about most of the guys on the group, but when I am threading, the last thing on my mind is snoozing. For me, anyway, it takes a huge chunk of my attention. Bill.

Dont spend the extra money. Threading to a shoulder is common practice.There are some tricks of the trade involved. Now you've gained some respect for professional machinists. :)

You can cut threads between centers. Leave a little extra material to clamp the dog on then cut it off later.

And never part between centers, at least not all the way through. Unsupported spinning parts can hurt you.

Where is a good source for understanding this technique?

Crash> Threading to a shoulder is common

Hmm, I wonder if a mandrel would work for barrels.

That was tongue in cheek. In a metalworking class at a local Tech college, I saw a 3 or so HP Bridgeport vertical mill with braille labels on it.

My idea of realistic is NOT doing a Helen Keller on a big machine while big cutting tools are moving.

I like to cut a "runout groove" where the threaded secton meets the shoulder. This is at least one threadwidth and a little deeper than the thread. You can do it with your parting tool. You still have to be alert but when the threading tool enters the runout groove disengage the threading lever and the tool just sits there in the groove as the part turns. This allows you to back the tool out and set up for the next pass at your leisure.

I agree with Randy. Fainthearted? No. But you really, really need to pay attention when you get close to this end of your threading. Bill.

Odd..I can thread on my lath up to about 1000 rpm, right up to a shoulder. Works pretty good

I could see that coming. I rarely single point threads, but when I do, my Feeler HLV-H clone makes me look quite good.
