    Antique hand forged lathe parts - info please

    OK, for your consideration - some illustrations from a most authoritative source for all to consider. Here is a reasonably similar lathe tail stock center and a square tenon drive socket on a lathe spindle. I think they support the idea that the parts I present here are quite possibly parts...

    Antique hand forged lathe parts - info please

    Anything is possible I suppose. The L shaped twisted and pointed piece in the last photo is identical to the tail stock of very old spring pole type lathes as shown in woodcuts printed in history of machines books I have, so I think it is quite possibly from a lathe. The right end of the shaft...

    Antique hand forged lathe parts - info please

    Here are the sellers comments: "Some iron parts to a late 18th or early 19th century lathe. The large gear, which is missing 1 tooth, is about 14 inches in diameter. The small gear, which has a poorly cast tooth, meshes with the large gear. The crank is about 13 inches in length. I assume that...

    Antique hand forged lathe parts - info please

    More photos. I am also looking for comments about how they were made, especially regarding hand forging. I am thinking these may possibly be something pretty special. I am not certain what I should or will do with them if they are (or are not). Any photos of similar vintage lathes wold be...

    Antique hand forged lathe parts - info please

    I have recently acquired some antique hand forged lathe parts. The big gear appears to be sand cast. I am looking for any information or opinions anyone wishes to provide and especially any possible references to date them or titles of books on lathes of this vintage.

    Antique air compressor tank - inspect & test or replace?

    As a P.E. too I must say that Joe has done a great job in advising all of you here regarding air receivers and the dangers they present. From personal design experience in the air-conditioning industry, pressure components and piping etc used there have to have a test pressure of 5 times max...

    Used Index Model 55 at HGR

    I had and used an Index 55 for over 35 years. It is a great machine - better than a BP. It weighs about 2300 lbs as I recall, and had wide knee and saddle ways. It is a very stout machine - nice and rigid. I may have a manual copy but I will not be where it is for some time. I still have lots...

    Gorton Question- 0-16 vs 0-16A

    I have a Gorton O-16A mill with the universal milling head and the spindle is for the Gorton proprietary collet - 1/2 inch max bore. The universal head tilts side to side, nods front and back. and traverses in and out. There may be spindle differences in the two different types of heads used on...

    How do I date and identify this old lathe - what tells the story

    The Stark lathe I have has a pretty low serial number stamped into the bed and came with both a cross and a swiveling compound slide both with lead screws, and a double lever actuated slide assembly with settable travel stops. As I understand it, Stark started in business in the early 1860's...

    How do I date and identify this old lathe - what tells the story

    Joe Thanks for your thoughts. The lathe is an enigma to me too - that is why I bought it I guess - no practical need or use for it - but it should make a nice display model. Really, the attraction was its unusual nature and the fun of the research trying to figure out what it really is, and...

    How do I date and identify this old lathe - what tells the story

    The use of brass for the head stock casting, the tail stock casting, and the head stock flat belt pulleys and gears seems like a significant departure from normal practice. My Stark from the 1860's is all iron except for the bearing shields. My Sebastian from the 1880's is all iron too. So are...

    How do I date and identify this old lathe - what tells the story

    I intentionally chose to start a new thread here because I wanted to develop a more systematic approach to identification and dating based on observable design features and measurable characteristics, rather than one based on Looks like and I think I saw something similar in ...

    How do I date and identify this old lathe - what tells the story

    Thanks Larry. As is the seller told me the collet draw tube does not pull out. He did not attempt to unscrew it. One of my first acts will be to unscrew the collet draw tube and determine if there is a collet in the spindle that is hidden by the chuck that may be screwed onto the spindle nose...

    How do I date and identify this old lathe - what tells the story

    This is the lathe discussed in a prior post - "another odd old lathe to ID". I bought it and had it picked up - and no - I did not pay the asking price. I will have it in my possession in about a month or so. Until then, I want to start researching it and learning what I can in the process. When...

    another odd old lathe to ID

    The old lathes I have worked on all used square head bolts and nuts. I noticed the use of hex head bolts on this lathe. When did hex head bolts become common and what if anything do they tell us about the date of this lathe - assuming they are original. Was the use of hex head bolts and nuts...
