With say a cylinder it easy for me to think of some simple measurement say with a dial gauge to determine accuracy. How is accuracy specified for a lead screw? I am not a machinist but a

This guy makes new ones. http://www.millermachineandfabrication.com/products.html The slide screws also differ depending on if the lathe has large or small dials. Yours should have the small dials,

Would a 9" originally purchased by the corps of engineers in 1952 be military spec?

I saw somewhere if is a 5L470 for the 16 speed v belt set up. Is that correct ---In southbendlathe@..., <southbendlathe@...> wrote: I have a horizontal 9a v belt and i need to know what size the

I have a horizontal 9a v belt and i need to know what size the belts are? The belt from the pulley to the lathe is a b42 not sure what the belt is from the motor?

 The stack up height of the A/B apron for the crossfeed was set with the apron cross feed gear they are marked M forminus and P for plus, a common line card listing would be M 10 for minus .010 The

Thanks for the information. I am trying to approach this with my own attempt of order. My first step is acquisition of the A and B apron. The cross feed screws seem to be a bottleneck as well. I have

 John, if you are referring to the apron lead screw,there were three specs: standard; tool room and military. the military specbeing the best. these were sorted as they were ran in production.If

We have a new member and his pin would looknice. Comment from user: Principal Bibi fathimaCollege Bangalore I have two lathes and a 7"shaping machine Jim B.

Yup. He has it on eBay. I know someone with a 16/24 with a bed worn so much it has like a raised ridge on top of the V ways for at least 1/3 of the length.

I'm pretty sure that they're very similar, but not identical. The 16" bed should be a tad wider. I think a friend of mine has still a brand-new 8' bed for a 14.5" lathe (the bed was bought

Do a 14.5" and a 16", both under drive type, use the same bed?

Yikes, the legs are missing........ with that short a bed, it will tip over to the left , real easy. I know I have a 380Y with the legs and QCGB. If that is the correct tail stock, I think that is

Has power feed but no gearbox. http://www.ebay.com/itm/171156656620

Anyone on list in Philly area happen to know hours for Cook Machinery ? I need to pick up some toolholders for my lathe . Rick

John, You are correct. SB did claim that the lead screw on a tool room lathe was of higher quality then on a standard lathe. But the conversation is about the acme screw for the cross feed. I do not

Varying accuracy are claimed for different models of SB lathes lead screws. Also the different suppliers of acme stock makes assertions about high accuracy. What is involved and how is accuracy

Hi just wanted to say I got my lathe running today I made a nylon washer to put between the collar and the shaft casting worked great no problem. I ran it for a while oiled it up real good it runs

Thank you Jim, I have cut acme threads to fit a worm amce cast iron nut on my tail stock. Alec Ryals
