Re: I Need a 3 Jaw Chuck

 

There are times when it's nice to have the center of the turned area coincide with the center of the lathe's X-axis. Less lost material, for one thing. If you're doing a cleanup cut on a shaft, for example, you don't want to lose a significant portion of the shaft. The better the TIR, the less you lose. If it is critical, you should be using a collet or dialed in 4-jaw chuck, but not everyone has one. If you need the utmost accuracy, you should be turning between centers. But they don't even teach that in machining school now. At least not where I'm attending. I know about if from extensive reading of the old info in literature from as much as 150 years ago. Once upon a time, no one had a chuck. Centers and a face plate, and dogs to lock the part to the face plate.

There were amateurs then, too.

Novice question here.. I see everyone is giving a TIR (Total indicated runout) reading but not how it was measured. Over a year ago I purchased a Sanou 6” 3 jaw chuck along with a backing plate that was predrilled but needed the boss and face machined to fit. When done I put in a precision ground rod and measured it 4” from the tip of the jaws. The TIR reading was .002. I was very happy with the results. Is this the correct way to measure the runout of a chuck? I did it this way because I did not think that measuring?just the diameter of the chuck is accurate enough.

My wife's effort to clean my shop would involve a bulldozer. So I made a deal with her. I will clean the kitchen for her, if she won't clean my shop. Works well for both of us. ;)

Re: 618 milling attachment jaw plates

 

Wow, that’s amazingly great luck. Good for you. My lathe is currently in pieces on my work bench in All of the major components. Over the weekend I did some more shop clean-up and finally got all of the “stuff” off the top of one of my benches. I was then able to move the lathe pieces onto my second bench and free up one bench so I can actually start working on projects. I actually bought the lathe in pieces and did not have the benefit of seeing it run. I got brave and pulled the motor over to the working bench and rigged up the wiring to test it out. I was delighted to hear the quietness of the motor as it turned on. No noise, no vibration, just quiet. When I unplugged it and it started to slow down I waited like an expectant father and then there it was. That lovely click as the centrifugal switched snapped shut.? Pure music. Given the 1939 age of the lathe, I was sure I was in for a motor refurb including new bearings. What a pleasant?surprise.

Best Regards,

John

Your results are quite good, to be sure!. ?I suggest measuring a few different diameters and distances from the jaw tips.

?Good Morning,?

so the lathe I am putting together did not come with the original counter shaft assembly. The previous owner tried to make a motor mount / counter shaft assembly and jerry rigged everything together. He never had it running. I removed and remounted to correct the alignment but the carriage he built is out of aluminum and flexes a little. Also using the motor to weight the assembly does not provide enough tension on the belt.?

I am considering buying an original assembly but the only one i can find is over 200 on ebay. Anyone build any that work well, or maybe some ideas on how to modify mine to add tension? Anyone have a cheap one they want to offload?

thanks in advance

I made mine 25 or so years ago and do odd jobs almost weekly on the lathe with no problems. ?

Re: 618 milling attachment jaw plates

 

What do you need??

Couple little case-hardened plates for the milling vise.? In a pinch I expect could do without the case hardening.? 2.5x7/8x0.25" and the same but 3/8 thick with crossed vee grooves for round stock.

Yrs,

Oh that stinks.? I lost my set screw on the threaded collar at the back of the lathe spindle.? I saw it fall and cant find it anywhere.

Looks like your milling attachment is useless now, so I could take it off your hands for you for $75.? Haha!

Can't help from here but that sucks!
As far as trash cans go in my "nest", wife won't touch it no matter how full!
Might have a comment though.?

I did a bad thing the other day. I was cleaning up my bench and dropped the jaw plates for my 618 Atlas lathe milling attachment in the trash bucket and promptly forgot to go for them as soon as I could do so. The phone rang, and someone came to the door to ask a question. I, forgot the plates, until the next day and my clean up wife had thrown the contents of the bucket in the trash that was collected. Now I am in the middle of a job and have not jaw plates. With the virus scare I am not allowed out of my cage so, do any of you have a set you want to sell or duplicate for me?
I have no steel stock on hand to make a set from so can anyone out there help? I would greatly appreciate it!
Thanks
