Mine works but the fine feed wheel is really hard to rotate, also the three position push pull stem is hard to move. I’m questioning if I can just pull it apart and just clean it. But I’m not wanting to have the mill down for an extended period because I screwed something up. . I can’t seem to find much information on this. But this type of information is abundant. Thanks for sharing your knowledge ! Have a great day.
There’s probably about 100 reasons why those pieces would be stiff Because I’m in an educational environment 99% of the time it’s from students hitting it with a hammer that’s crazy as that sounds when they’re hammering their work peace down they’re not watching where the hammer goes and it hits the stem sticking out If you can’t afford to have the machine down for a period of time, I would not take it apart if it’s still working some of these parts and we have replaced every part on these machines can’t be difficult to get I have a few other mill videos, or Andrew is taking things apart. We have a special station for stripping the head down where we take it off of the machine out of the shop and bring it up to our workshop repair shop, and the head can be stripped down at chest level, so you’re not standing on a ladder or anything like that, and it’s bolted to the side of a table And you have the perfect work for dismantling. Eventually, I will do a video on a full dismantle, but that won’t be for sometime. I hope this helped Ray
@@shopandmath thank you for the reply. It festered to the point I couldn’t take it anymore. I pulled the clutch and the trip arm. I pulled the gear out of the front and found it was packed with old hard grease. I cleaned out as much as I could and saturated it with spindle oil. Assembled everything and tested it. It works beautifully now but all the spindle oil is leaking out all over the table below lol. It was only temporary. But this machine has a grease zerk above it and I’m pretty sure it was not supposed to be greased, but oiled instead. So now I’m not sure what to run in it. But I’m going to pull it apart one more time and clean it out. Once I figure out what to put back in there. But thank you for your time and your reply. I hope you have a great day.
You can use anything to clean a surface plate just as long as it does 3 things 1 removes oils and dirt (lifting and encapsulating) 2 does not have an acid that will damage or stain the stone 3 does not leave a residue or film that will effect dimensional accuracy or have a high PH level to damage the parts that touch the stone I have seen someone clean the plate with some thing they shouldn’t have and the next day the part was welded to the plate (required a hammer to brake it free) Pure alcohol does leave a layer on the plate (I do not remember what it is called)
My problem is that the quill autofeed knob is almost impossible to engage either way. I can tap lightly with a small brass hammer, it will engage and work properly, but it should work with just fingers. Same with pulling out on the knob, which required pliers. Suggestions?
I tried drilling with a half inch bit into half inch steel plate using the auto downfeed and the highest feed rate but it wouldn't push through and it sounded like something was slipping. What am I doing wrong? Do I need to select a lower feed rate for more downward force?
This is tricky to answer. I kinda need to see it to understand what’s going wrong. There is only a certain amount of force that the power feed on the quill can produce. Usually, if it’s too much force, it will pop out of gear and not allow the gears to get damaged. Maybe instead of using the power feed, place the feed handle on the power feed, place it in neutral, and then hand feed through the power feed unit to find out if the tool cut smoothly, or you require more force to get the proper chip formation I know my statement might be a little difficult to understand. I hope that you can understand what I’m trying to explain. Ray
Hi kevin, unless I can see it and touch it, I’ll be honest any advice I gave you would be blind When you turn the machine on, is there any type of grinding?
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
Could ANYONE please refer me to a document or a video on adjusting the power feed clutch?? I know how to set the quill trip play, but no one ever explains how the clutch works and when it needs adjusting and how to do so. It's making me crazy....
Just bought a Bridgeport clone. Thanks for the instruction, you're an excellent presenter. Very well done. (I also subscribed)

Qual é o modelo desta máquina quero achar o manual na internet ou manual de reparos
Good demonstration. Nice video!

Quill won't engage . Any ideas
Hi kevin, unless I can see it and touch it, I’ll be honest any advice I gave you would be blind
When you turn the machine on, is there any type of grinding?
good one thanks
Glad you enjoyed it

We have a lot of machines
Sometimes we repair the power feeds next time I will try to remember to make a video of it
Thank you for commenting

Thank you sir.

THAT'S WHAT THAT LITTLE HANDLE IS FOR
I need to be a little bit more specific than that there’s a couple little handles
Could ANYONE please refer me to a document or a video on adjusting the power feed clutch?? I know how to set the quill trip play, but no one ever explains how the clutch works and when it needs adjusting and how to do so. It's making me crazy....

Your clockspring is set too tight. The spindle should not jump up when the feed is disengaged. It should remain stationary.
