    Potentiometer causes motor drive erratic behavior, but only when mounted/grounded

    Hi all, this is an area where I am normally in my comfort zone but this issue is odd enough that I have run out of ideas and ruled out the causes that make sense to me. Take any of my reasoning, editorializing, leaps or conclusions below with a grain of salt, since I clearly am missing...

    Repaired OEM Bridgeport lights

    Slowly going through a few things on my new-to-me Bridgeport series 1 2J (1.5hp) mill, both of the originally-installed lights were non-functioning. Perhaps someone can comment if these are an actual bridgeport accessory, versus if this was just something outfitted by the dealer These are...

    800 mile Bridgeport move with 1995 Ford Ranger

    This writeup is split over two posts in this thread due to the attachment limit -- "today" (now a few weeks ago), I picked up a series 1 2J head Bridgeport I bought at an auction in the Chicagoland area, and drove it home to Northern VA. Originally when I bought the machine, it was at the...

    [How-To] Mounting a Z axis DRO on a Bridgeport (Clone) Quill

    Hi All, A few years back I completed the DRO installation on my mill by adding the Z Axis to the head, that is my mill is a bed style where the head raises and lowers not the knee or table. However, I found it not be as useful or at least user friendly as I thought, mainly due to the fine...

    Highest Quality Rotary Table

    What are some of the best Rotary table brands you can buy? I only buy tools once so quality of the most important thing. I’ll happily buy vintage if people truly think they are better. I have a Bridgeport (pictured below)

    Bridgeport x/y bearings

    Good day, I need some advice. I have taken apart my 1955 round ram table and saddle to clean out the grease put there by previous owners. What a mess. While apart, I am curious if I may need to replace the bearings. The left side of the table, there are two Norma bearings that are 20mm x 47mm...

    Spiral milling

    I filmed this over a year ago and just got around to editing it. It's shows me setting up and cutting a course pitch spiral in a piece of 32mm silver steel (drill rod) for the column of what became my Quorn project. Enjoy:

I found one within 1.5hrs from me. It's a Bridgeport J head 8 speed SN 61006. I looked at it...

    [Newbie] J-head And Hardinge Restoration (1957-ish)

    Howdy all, I just posted this over in the Bridgeport section http://www.hobby-machinist.com/threads/1957-series-i-j-head-and-1957-ish-hardinge-hlv-new-to-me.51795/, but figured I'd slap it here as well. I acquired a couple of (free!) machines which came from a small maintenance shop and were...

    1957 Series I J-head And 1957(ish?) Hardinge Hlv [new To Me]

    Greetings All, I just acquired - for the low, low price of nothing, two things: 1) 1957 Series I J-Head Bridgeport - pancake motor 2) 1957 (near as I can tell) Hardinge HLV Lathe Overall, I don't think that - given their age - they're too bad off. They certainly need some extra special TLC...

    Smooth Arc Function

    Last year I bought a 3-axis DRO to go with a new BP clone, and I was excited to find out about the smooth arc function, however I cannot get it to work. I assume there are parameters I do not understand, but I'm a smart guy and I am at a loss. For reference, it is a DRO Pros 3M, Z on the knee (I...

    Questions About 6" Bridgeport Mill Vise

    I picked up a 6" Bridgeport mill vise at an industrial garage sale for $50. It works perfectly, has little wear, and only one pockmark. The only thing wrong with it is the jaws are missing. I can make new ones, but I have a couple questions: What kind of steel is best suited for mill vise...

    Testing A Rotophase Converter

    I'm not experienced at all with 3 phase, so I have a question about how to verify that a Rotophase is in good working order. My brother is selling off some equipment, including a 3Ø BP and the converter. Probably the BP will be first to go, but then there's nothing left to run off the...

Then I turned the stop all the way south on the Z, pulled the quill lever, smooth all the way down Just about 5.25" of travel. Then I...
