If you have a Bridgeport mill and not ordering parts from this great people you are crazy. I have rebuilt my 1965 mill with most all of there great parts and videos
Good morning friend, I have a milling machine similar to that Chinese brand and the automatic of the boom or spindle of the head does not work. the lever engages well but the movement does not work. Do you have a video to repair it? I would be grateful if you can help me. Thank yo

Barrywhat did you do to eliminate the oil system? My quil drips oil and makes a mess. Heather said there is a felt washer on top of the quill which I noticed you didn’t put in on reassemble. Please explain. What is in the rebuild kit if there is one and what does it cost? God bless. Frank
We use either sealed spindle bearings or open bearings with the high speed grease. If your spindle bearings are open and still good you could just get the grease and grease them yourself.

Barry, Thanks for all the great videos about Bridgeport milling machines. Will you please make a video specifically about all of the various J & 2J head noises, and help us to troubleshoot our possible issues. Thanks!
@@HWMachRepair That's unfortunate regarding the sound coming across correctly in the videos. At work, we have several Series One Bridgeports, each with their own issues! One however is making a horrible sound like the bull gears are clashing, but when the variable speed is cranked up, the sound lessens more and more. Could this be a simple adjustment, or do you think it needs to be looked at? Again, Thanks for all the great videos!
@@HowardWertz We do have a flow chart on head noise diagnosis, or please give us a call and one of the head techs can help you diagnose the noise: machinerypartsdepot.com/technical-support/variable-speed-milling-machine-head-noise-diagnosis/ 1-800-285-5274
My clone is all metric. I just had to match up the reverse pull knob threads because my pull handle was missing. It was a M4 x.7 I believe. Also the hole in the top of the micro screw for the reverse trip lever must have been a metric size. It was too small for the bridgeport replacement part. I had to ream it out to 1/4". So just a heads up for folks out there working on asian clones, that a lot of these parts aren't sae like the bridgeports. It will save you some headaches when ordering....measure first.
During the inspection phase of this repair, I'm sure all the parts and pieces are measure for proper sizing. so, my question is what is the proper clearance between the quill and the housing (head)? what is optimal and what is excessive? Also, if the housing is out oftolerance what if anything can be done for a repair?
Re: recoil spring: On my Comet clone I used my caliper depth feature to find the depth of the rivet head on the shaft. Then when I loaded the spring into it's housing I left the whole thing out about .100". It caught the rivet head the first time. My spring had broken diagonally near the inner end. I figured it was from having the inner end forced inward to catch the rivet, basically twisting the spring. I think the twist caused the diagonal break.
hello and congratulations for your videos and share your videos, I am from france I own a milling machine kondia vf-1 spare parts and maintenance is it the same thank you very much
I couldn't get my clutch to seat deep enough to gain access to the snap ring groove, thanks tomorrow I'll get a piece of tube & drift it into the worm gear. I had the thought the gear on the pinion was out of place by about 0.040". Thanks a bunch.

My new quill skirt comes back up with the spindle and sticks up out of the hole. Will this be a problem or can I count on the cradle hold it down well enough?
I have a Bridgeport with J1 head; Does the machine has to be running in order the quill feed selector work? when my Bridgeport is off, the selector is stuck at one or maybe two positions of the selector and I cannot move it to any other position ; I am wondering if something is wrong with the mechanism and gears( although I cannot visually see any wear on them) or this is the way it should be.
Yes! The only way to move those gears is while the machine is running and the downfeed is engaged. This is true for all milling machines with downfeed capabilities. -Heather
hello sir, can you help me to resolve my milling head shakes when running and its vibration cause run out in tool holder. dahlih gh2200v milling machine. could you tell me where i can check, find resion and fix it. many thanks from viet nam
great video--thanks for the detail. i did notice some chips and shmoo at 12:20 in the 3speed gear area. i have watched every one the videos multiple times. i think i can disassemble, clean and reassemble the whole thing in my sleep. i also notice that the only time you mention bearing orientation is on the spindle bearings. do other bearings (sliding housing, bull gear etc) have particular orientation. i am currently searching for suitable mill for my hobby use. would love to see rebuild of any other equipment--surface grinder, one the Lagun's omni present in several videos, lathes of any brand.
Hi Charles, other than the spindle bearings, the bearing orientation dose not matter. We would like to do other machinery, it's just finding the time and having the machines in there to go some of them. Thanks for your suggestion.
Without getting into the records of this head I wouldn't be able to tell you. There aren't any set parts that we replace every time because every head wears differently.
thank you for this great video I have a question I have a Bridgeport with a non-variable speed head and found one has come on the market which is a series 1 head variable speed are can this just swap out? and if soo in your option would you swap a head? i know the variable speed is nice to have but is there any downsides to them?
Yes, the heads can be swapped out between a step pulley and a variable speed. Most people prefer to have a variable speed although I love my step pulley heads. You can turn your step pulley into a variable speed by just putting a VFD on it. We sell one for just $600 that uses your existing motor and pulleys. There are downsides to both heads when it comes to general wear and tear of certain parts. Please give me a call at 800-285-5271 so we can discuss this further. -Heather
No, we don't have anything that goes into the cradle assembly yet. I'll put it on the list though. In the mean time if you get into it and have a question you can give us a call: 1-800-285-5271
I followed the Disassemble/Reassemble the Quill video exactly, but only for the Power Feed portions. All seems to work, except the quill does not move automatically. I have the Feed engaged, the Quill brake off. I tried all three speeds, nothing. While it is engaged, the handle will move the quill up and down without binding. Suggestions??? Bob

It's all in the spindle bearings. You can either use sealed spindle bearings or use the red grease that we use on the open bearings. Along with the shielded top bearing it turns the system into a closed system that you no longer have to oil. You can give us a call with any other questions if you prefer: 1-800-285-5271
@@HWMachRepair Ah I see, I had thought that the open bearings with the red grease did not qualify as a "closed system" Are the japanese bearings you use of a greater precision than the sealed timkin bearings? Or is there some other reason that you use these over sealed bearings?
@@johnfurr8779 In our open bearings we use a high speed aeronautical grease. Once the grease is packed into the spindle bearing you can't use oil or it will degrade the bearing and cause it to overheat, that is why it's considered a closed system. We had a head come back in for work recently that we had packed 20 years ago and the bearings were still good. We just cleaned and repacked. We prefer the open bearings mostly because that's what we have always used. We carry both because we want to give our customers options.

Ordered some parts from you yesterday and I'm sure more to come. These videos have helped me so much in my endeavor to bring back my Florida yard art Bridgeport. Are all the Series 1 quill assembly's the same? The machine I picked up has a nmtb30 taper. I have a parts head with r8 in it. Can I switch these out being as I have so much r8 tooling? Thanks..
The quill housings are the same between the Variable Speed and Step Pulleys on J style heads. You can change out the spindles, you will just need to switch over the spindle and the nose piece.
Hi love the channel. Does anyone know the name or part number of the shaft that operates the worm gear that allows the head to tilt clockwise or anti clockwise. Mine has snapped off within the casting while attempting to bring it back to 12 o’clock following delivery 🤦♂️
How similar is a series 2? I have one that the quill is sticking really bad in, and think it just needs to be cleaned up (I think it sat for a really long time before I got it). And thanks as well for the great videos, I love the extra time you guys spend to include all the part names/numbers for easy lookup to replace.

WD-40 will actually produce rust once it starts to dry, fortunately these machines won’t -likely- be in overly humid environments and not just sitting.
