Im 65, and I just got instructions from a 20 something years kid. Who made it make sense. I'm so proud 🥲

Bro, you came through for me 😮. Thanks man, you rock 🪨

Bruh, very good video it was spot on. And Thanks for not rambling on about a bunch of unnecessary stuff. Thanks from Florida.

July 9 2022, The Hobby Machinist; Practical limits of an R8 Spindle? The R8 collet system's limitations is not the only concern. The spindle bearings take a beating when the machine is pushed too hard. On a previous job, I had a co-worker that fabricated a 12" fly cutter to use on a Leblond mill with a 30 taper spindle. It wasn't long before the bearings were trashed in the spindle. I didn't see the bearings personally, but was told they came out in little pieces when it was disassembled for repair. I have a few 1-½" end mills, but they only get used on the Cincinnatti horizontal with a 50 taper spindle... and I'm pretty easy on using them. I'm pretty easy on my machines... I want them to last my lifetime, at least. -Bear ++++++++++++++++++++++++++++ I can’t provide a useful answer to the question but from the sidelines I see this as a very interesting and relevant topic. How exactly will people coming up learn if they don’t have the long time mentoring from senior hands, fathers, etc? Yes, we learn from our and others’ failures but hopefully it doesn’t cost us a digit or two in the process. How do you find out how short is too short to hang on to, or how long is too long to safely stick out? I have to think much of this is so ingrained in the brains of those of us who have literally grown up around building things. We have developed some kind of sixth sense of what is going to hold and what isn’t, and what is just plain crazy so don’t even go there. I have a new hire at work, he is not stupid by any stretch, but almost every action I see is lacking in good engineering practice. The blade on a razor knife extending full out to cut a piece of paper; pushing the off cut side of the sheet on the table saw; bearing down on the drill bit even though it’s clearly dull and now smoking it’s way through the wood, etc. He’s nearly 40 years old and not in his chosen profession now (he’s actually an architect but isn’t able to work here in that field yet) but still, some of these things are what I know as life skills. How can somebody make it this far without picking that up? Back to the real question though, how does the next generation learn this stuff when the old guys aren’t around anymore? As much as I like charts and spreadsheets I don’t think that’s going to do it. We have charts for things like feeds and speeds but as soon as we dig them out we supply the caveat “..just remember these are only suggestions..”. Maybe they do provide a starting ground but again, the background information of how much horsepower, what material, etc etc etc would make for an impossible number of variables to be useful. There’s got to be something inside lurking in the background to say “whoa, that’s not right..” But how to get that across in less than a lifetime? -frank ++++++++++++++++++++++++++++++++ Ed and Jr asked for your email and you seem to be failing to address this issue. So Ill address it. Ed and jr is right. That jason hull is a lame brain that doesn't up from down. How many forums, reports and other tech bulletins would you like me to post here on this topic? If you aren't aware yet what the real issue is, then Ill explain it in more detail for you. RUclips is full of people teaching each other bad habits that have no place in the shop, then you have people like jason hull tossing a monkey wrench into the mix defending those bad habits. If you're going to post videos and engage in something, do you think it might be helpful that you do some research first before doing something that is, on the books, WRONG and will cause damage to your and others machines seeing how blindly people follow other people off a cliff? Whats interesting is ed and jr pointed out on their original comment that he didn't think you would listen and I have to say, it sure seems that way now doesn't it?....

So I said something about the limits of an R8 spindle and that's considered negativity and hate? Where is your email address. I have some things to send you if you want to listen to that muffinfrock who has no clue about anything he spewed out here. I cant post it here because YT wont let me. That clown who long winded his hate speech is exactly what I'm talking about is wrong with YT. You go ahead and listen to him and you will be sending your entire milling head in for a complete rebuild sooner than later. And FYI, My Bridgeport is over 40 years old and I've never had to have the head rebuilt, it has its original spindle and its in great condition BECAUSE I FREAKING OPERATE IT WITHIN THE SET LIMTS OF THE R8 SPINDLE SPECS. Now what's your email. Ill send you everything you need from other experts who will say it like it is if you want to ignore what I said and listen to your hate ape who had to mouth off on my comment. Its because of jerks like him that I start hostile commenting because I've been though this so many times I'm sick of the freaking games. Email add. Ill send you all the stuff you need on the R8 spindle and what you're in for if you want to go down that road. The fact that he thinks balance is something on a fly cutter is more than enough proof to show he has no clue what he's talking about. You have a single point loading on the work piece spinning around many many RPMs. Its imparting a tremendous force on that R8 spindle because the spindle is small. Its also tearing up your bearings. Balance is gone and has sht to do with anything. I'm so SICK of these whiners continually interjecting acting like they know something when they clearly don't!

All thats going to do is ruin your R8 spindle on the milling machine. Im just not feeling giving you all the reasons and you aren't going to listen to any of them anyway.

Thank you for the input

I watched your video just now and finally found one that actually shows you the wiring. Many thanks for your video. I will subscribe and like. Take care and stay safe. From: Petawawa, Ontario, Canada.

You have no idea how you fucking save me. I am at hospital right now im not an electrician i dont want to be embarrassed but fuck!! Thank you! I change almost 50 lights today.

Where do you get the rollers rebuilt im in Ottawa

Very well done Matt. I appreciate your step by step approach to figuring this out.

What if there is one led bulb on same drive. How will be the wiring combination? Both blue are connected or one left open (wire nut). Thanks

My understanding is that the trigger is an on/off switch, and doesn't do the same thing as a pedal. Mine comes tomorrow, so hopefully I'll find out for sure.

All the LED tubes will be working with all ballast types without of damage or broken of LED driver of inside an LED tube

not exactly a pretty surface finish ... I'm guessing speed was the goal ..?

I know I am incredibly late thank you for posting. So if you would like to fix something like this again for the future. With this machine use mig and then just plug weld till its filled. This will allow it to accept the weld without blowing holes or excessive heat.

Just got a sub, thank you . I work in maintenance and know things here and there but this has help me tremendously

Hey Mat👋🏻 Very nice footage, I'm currently working on a BK 117 for the Microsoft flight simulator. In that context I wanted to ask you if there is a possibility to get the uncut cockpit footage from you. It would help me a lot with implementing the instruments and systems properly. There's almost no videos out there to work with.

Do you have a video with two ballast?

you're a life saver, thank you so much!

This is exactly what I needed. Thank you so much!!

I would love to fly one of these BK, 117's

Thanks...exactly answered my question in a nice and short and concise video...well done!

Thanks for the video. Helped me confirm what I thought I needed to do with the wires.

The difference is that the electronic ballast is instant start and the magnetic one is rapid start. A rapid or programmed start electronic ballast would have the same wiring as the magnetic ballast.

I got a planer just like that , with the same roller problem, where do you send the Roller to rebuild ?

2:50 was your MIG hose missing an o-ring on one of the sections?

Where did you send your rollers for recover?

Hi Matt, mine won’t stop running. Haven’t done much troubleshooting but where would you start? Thanks. PS: good job on the repair. Inspiring for sure.

WOW. Thanks so much for explaining this so easily. I had to replace a bad Magnetic Ballast with a new Electronic one that I purchased & install new LED tubes. Because of the different number of wires & colours I watched MANY videos, but only had the confidence to do the job after your explanation. Worked out perfectly!!!

Got the same welder, love it. Tons of adjustments to help us novice guys. Tossed the switch on the torch and just using the pedal. Look up ine fluxcore wire, save your money and don't buy gas.

Will this cause it not to charge/ fill the tank?

Everyone starts from scratch brother ⚡️😎☝️☄️

Thanks for your video, was going to give up installing the replacement ballast until I came across your video.

I like programmed start t8 not led.

*Awesome tool.A must have for bigger size projects.Easy to see line in lighted areas.Highly **recommended.My** crews love it.*

Where do I send them

Where do I send my rollers to have them refurbished

I'm really sure you can build it yourself. I did this 2 weeks ago thanks to the Woodprix plans.

Getting ready to return the ballast I just bought but thought, "Hey, let me make sure this can't be wired somehow. It was made for two T8 lamps so maybe I'm just missing something." Watched this video and 2 minutes later I had my lights back. Thanks for the simple and straightforward video!

hi i see a video from startup bk 117 inside in yours .is it possible please contact me over facebook .have no IG or tw.sorry i need that video please to make a sound for my bk 117 in X Plane 11 will be cool to have that sound ,greetings from germany markus

Thank You for this. I just bought the replacement and was dumbfounded at the difference in wiring. Nice clear accurate explanation.

Very cool video!

Whats the range like from the receiver to your laser level? Thanks

What software did you use for the design?

Please could you put the MTS 211 publication. If I would like to ask you, Jesse, is this machine capable of MIG welding aluminum and does it need any additional attachments? Greetings friend. .

Good job.pls,stay safe and stay connected.

Full wstch to your beautiful places.

the electronic ballasts suck and LED lights suck. i still use f40t12 fixtures that are pre-heat with the starters and some of the ones i have are from the early 50s and still work no issue. but the new electronic ballast struggles to last 5 years and the tubes dont last as long either, and LED lights are just harsh and boring and start to flicker.
