Alright, wow, its been 2 whole years since i bought this thing. I wanted to put this thing back together a long time ago, but i got lazy and had other things i ended up doing. In fact, I nearly cleaned and painted everything very early after my purchase. Had removed grease, gunk, chips etc. But...

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...

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...

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...

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...

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)

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...

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:

Hello everyone, I've been on this site for a little bit but this is my first 'real' post on here. I'll start out by saying I am a machinist by trade- I started in the tech program in high school and have been doing it for about 8 years now, but I also have machines in my basement and love to do...

Hello everyone, I have read so many helpful things from this site over the years that led me to my first lathe purchase a couple years ago (PM1236) Right now I'm looking for a knee mill under 84" tall. I found one within 1.5hrs from me. It's a Bridgeport J head 8 speed SN 61006. I looked at it...

Breaks down the serial numbers by year of manufacture.

Dear All, I am delighted to be allowed to join the forum. The rules state that I should begin by posting an introduction: I hope that I'm doing this in the correct place. I enjoy making, fixing and exploring things. When I'm not working, or messing around in my home workshop, I grow...

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...

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...

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...

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...

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...

Today, while continuing the setup and contemplating the CNC conversion of my new mill, I decided to check the full range of all the axises. X 29.75", Y 12.25"... 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...

I'm wanting to start buying some equipment to start my own shop but I don't have a ton of money to work with. I've seen old Bridgeport's with CNC controls on EBay for $4500-$6000 but I've also been told auctions are where I will get the best prices. I guess what I'm wondering is if anyone has...
