Fabricating a new Hydraulic Suction Tube for the K&T Mill

[@RobertKohut]

Another great Sunday morning! Thanks for your great entertainment and efforts!!

[@raincoast2396]

A high level of craftsmanship skills and pride in ones work shows in the final product. When "just" good enough is not good enough! Way to go Adam. Cheers.

[@milspecmachine]

Looks Awesome Adam another outstanding job thanks for sharing the video with us I'm learning a lot from you on a daily basis.

[@esoomreltna]

Adam, Very nice!! You really do know what you are doing and it is a delight to watch. Eric

[@josephmagedanz4070]

Nice repair and fit, Adam. Everything is looking good. See you at the Summer Bash! Joe

[@tubalcain1]

Nice fab on that hydraulic suction line! You do good work buddy!

[@MikeDittmanmachining]

You always make it look so simple and easy. One day I'll get there... May be a little while.

[@reideichner8597]

Nice and clean, Adam. I hope you found the problems and get it up and running soon. Thanks, Reid

[@artemiasalina1860]

Fingers crossed over here. Best of luck on the reassembly.

[@danielwerger5641]

Very cool Adam....! Thanks for the video...! Cheers, Daniel

[@Barefoot3us]

Adam, Nice bending job and great position for the strainer off the bottom.. Stay-Silv did a really good job for you. You have to love the capillary attraction when the fitting is hot enough and it melts the Stay-Silv and sucks it into the joint. Nice work. Best, Jeff

[@paulbuckberry7683]

You make everything look so easy..........that's skill for ya!!!!

[@bobtroxell5733]

Sweet! Nicely done Adam!

[@mattcurry29]

Hey Adam, Nice work on the suction line. With all the small things you have found and the test on the pump and relief valves I believe you have track down the issues. Good luck with the reassembly. Matt C.

[@haydenc2742]

Nice! That lathe will happily be slinging chips in no time!

[@billdlv]

Looks good Adam, way better than the hose for sure. I used to do some bending, flaring, and silver brazing at my old job I miss that. Some of the guys were really good at it and showed me a lot of tricks. Glad you have Gill to help put it back together that will make the job a lot easier.

[@Abom79]

Bill De La Vega I like the silver brazing, and wish I could do more of it, just not much of it in my shop anymore. When done right it provides a strong and leak proof joint.

[@shawnmrfixitlee6478]

Great job Adam ! I sure hope and prey you got to the bottom of the problem .. Keep us in the loop man .. Thumbs up !!

[@Abom79]

ShawnMrFixit Lee We'll keep the updates coming Shawn. Thanks.

[@thatlittleworkshop]

Great job on the K&T so far Adam. Troubleshooting hydraulics is always a bit of a chore, especially when nothing looks drastically bad. In my opinion, from what I've seen, I think you're right on the money with all your diagnosing. I've seen a few jobs where its literally hours of work to replace a 50 cent o-ring or a 5 dollar seal that shut down a machine. Looking forward to seeing the K&T throwing chips. Thanks for another great video. Ian Little

[@Abom79]

Ian Little You got that right Ian. We've done many jobs at work that only needed soft parts replaced, and the time and effort to replace them is immense, plus the downtime for the customer.

[@trkycustoms]

One step closer to seeing it in action .... Good and thorough video .....

[@larry527az3]

Excellent job on the suction tube Adam, I do a lot of that kind of work for a living so it's nice to see someone else with skills doing it too. Can't wait to see if all of the small issues you have found will add up to the entire problem with the mill. Like you, I suspect it was many small issues versus one single issue. Thanks again for the great videos!

[@kenzpenz]

Great job, looking good. Getting closer and closer yea !

[@WallysPlace66]

It's fun to build something as simple as that filler tube, and when it comes out fitting just right it gives you a sense of pride in a job well done. I really enjoy your videos. I resubscribed under a new channel but have been watching for about a year now.

[@jimliechty2983]

Great job Adam!!.....although it wasn't completely necessary to teach all of us the details of how everything works, I am sure by doing it, it will have a benefit to you understanding yourself all of the particulars in the long haul....again....great job!

[@Abom79]

Jim Liechty I know many of the guys have enjoyed following along and learning how this system works, so that's why I explained some of as I went along. Thanks Jim.

[@3347861]

Count me in on that group, Adam. Good stuff...

[@one4stevo]

Nice job looks like a factory part well done

[@granpasgamings]

Cool video Adam,well done here.

[@craigleemehan]

Looks like you are really getting a handle on the inner workings of the K&T. When you first opened it up, I thought OMG how can anyone understand that mess of gears and hydraulics. I think you have done it right by methodically inspecting and looking for problems. The difficulty of disassembly and reassembly makes changing one thing at a time and checking if the unit is fixed, realisticly impossible.

[@RandallMoore1955]

Just right on the tube Adam. Lookin good.

[@robertkutz]

adam good job on the hydraulic line ,can't wait to fire it up.

[@craigs5212]

Great job Adan, I am hoping see you at Stan's. I do aircraft tubing every once in a while there is no way to hit it first time, so I just take a scrap piece of tubing and mark it off say in 2" spacing between bends. Go and bend it, see how it came out and adjust your dimension marks plus or minus as necessary. The second piece always fits. Craig

[@chemech]

Nice older tubing bender... when I needed to get one for doing 1/2" stainless tubing at work, I got one that needs to have an "anvil" riding in the channel with the tube... I need to work up a box that'll keep the parts with the handles... Also, it's nice to have a protractor - even a crude one - on the bender... Cheers, Eric

[@Abom79]

chemech We have a few of those benders and they work nice. I don't know the brand but there is a "W" with an arrow through it, the only marking on the tool.

[@duobob]

Abom79 Weatherhead. I have a smaller version of that bender for brake line tubing.

[@robertgiovannucci7144]

Another good video, Adam! Can't wait to see it back together and working. Ciao! Bob G Closet Machinist

[@jonhare392]

Love both videos today Adam. I had to laugh when you went for that last little tweak on your fitting. SNAP! I was actually thinking the same thing! Been there too many times. :-) your videos are brilliant and makes me want to find a good machinist that needs a shop rat to take care of maintenance while relearning the trade. I have worked on Swiss automatic screw machines back in the late 70's but I was not the set up man as my math is ok but that arithmetic always gets me in trouble. (My old foreman's favorite quote)! Got in to VW repair after that and met some amazing Porsche/VW machinists at Lightening Machine in San Diego who did all of the high end engine work in So Cal. I worked for them doing heads flywheels and rods and enjoyed it very much. My training was progressing but I took an opportunity to start a silkscreen business with my dad. I regret not staying in the trade. Although getting into construction did get me to Kauai in 1992. Btw could use another machine shop here. :-) see you at the bash!

[@llrustyengines]

Can’t wait to see the K&T makes some chips, good video .

[@danielrottino6230]

Nice Work really like the brazing job

[@jaydee123ish]

Excellent job Adam, pat yourself on the back. I really enjoyed that video.

[@Abom79]

Dave Graham I was quite pleased at how well that line turned out in the end. Thanks Dave.

[@petermundy3339]

Good stuff Adam and hopefully your thinking about a lot of small faults having built up to one big one is correct.

[@swarfrat311]

Hey Adam, Nice work on your suction pipe! That's a cute little bender. The only bender I've used is for 1/2" conduit and it's more substantial than yours! Good luck getting your knee assembled. Thanks for sharing your work! Take care . . . Dave . . . the Swarf Rat

[@krazziee2000]

looks good , nice work, thanks for the video

[@k5at]

Nice job on the tube. I sure like your tubing bender.

[@RyanWeishalla]

Between this video and SNS, a lot of good info on O-rings and sealing hydraulic systems. Hopefully you and Gil get some time to work on it this week.

[@Abom79]

ILGopher I have been working on it, but Gill has been living it up Las Vegas! LOL

[@workwillfreeyou]

My thoughts on strainers. Do not use them for hydraulic intake. Just leave the suction tube 1" off the bottom of the tank. Thank you. You are doing great.

[@jusb1066]

***** actually i agree with you in part, i think the strainer he has is the wrong one, it will all too easily allow it to pull in air and it lifts the pipe up too much from the bottom, there isnt very much oil above it, although i think he needs some kind of strainer still

[@darinspicer2753]

Cant wait to see k&t running again !

[@chucktipton9596]

The K&T's looking good Adam. If i were a gambling man I'd bet it works. Looks to me like it had several problems that compounded together caused the failure. Wish I could be at the bash, I would love to meet all you guys. It just ain't in the cards for me. Thanks for teaching us. Chuck

[@Abom79]

Chuck Tipton Thanks Chuck. Maybe next year!

[@pricetagg9730]

nice job look good..keep it up.

[@MrChrissy1r]

A little tip for the future, when bending pipe, there is a formula, I can't remember at the the moment of writing, but see Student Study Section, How to bend copper pipe accurately and efficiently.It's something like 1/"2 the thickness of the pipe plus the length of the bend ,, or something! This works with all round stock, pipe or rod of any size. Also you could have used annealed copper pipe , which you could bend literally with your fingers, then re heat and allow to cool to regain it's strength, because you are not dealing with high pressures here, to stop the pipe collapsing just pack it with damp sand, or use a couple of plugs , freeze it then bend it! Just a tip hope you don't mind!

[@oldschoolcopshop2194]

Adam Great Job with one possible exception, I wasn't clear in your video if you wire brushed the inside of the fitting after you brazed it. This should be done because you applied flux to both the pipe and the fitting. The heating during brazing will make a flux crust much like the flux we chip off after welding and it can break off in operation and contaminate your system. I always coat only the pipe or tube being pushed into the fitting with flux and never the fitting or what will end up being the inside area of where I am brazing. This way the flux will not contaminate your system and there is always the right amount of flux right where you need it. If you get a chance watch Halligan's video that he just did on brazing as it is spot on. I'm don't mean to be criticizing but trying to head off a problem if you know what I mean. Keep going as I want to see the mill up and running soon. Regards, John

[@Abom79]

Old School Cop Shop I mentioned on video that I bead blasted the tube and fitting after I brazed it, then washed it out with cleaner, and blow dried it. We're good to go there.

[@dangerrangerlstc]

Nice job. Almost looks like you knew what you were doing. Hope that fixes it. Looks like it's one of those jobs where a lot of little minor things add up to a big problem. Hope you don't have to take it back out again.

[@KnolltopFarms]

Nice! Thanks again...Aloha, Chuck

[@mikew9861]

great videos

[@rockityrock]

Nice job!!

[@fabpovilla80]

hola abom me gustaría tener el gusto de que algún día pudiera trabajar y aprender de un maestro como tu ya que en mi país es muy difícil tener una profesión como la tuya gracias por publicar este tipo de videos

[@63256325N]

A thing of beauty!

[@RambozoClown]

Looks great.

[@bcbloc02]

That suction tube will be a huge improvement! Did you take the piston components apart on those clutches for inspection? I am concerned you have excess leakage there.

[@12345NoNamesLeft]

bcbloc02 Are there more o rings in there ?

[@1jtolvey]

I CAN SMELL THE CHIPS ALREADY ! GREAT VIDEO !!

[@stanwooddave9758]

It's Beer-Thirty time, have yourself a cold one.

[@JRD77VET]

Great job on the pick up tube. The only point I want to add ( which you did ) is when lighting an oxygen acetylene torch, light with acetylene ONLY. Only add oxygen after it's lit so you do not have an explosion in the torch handle. It's rare but it could happen with disastrous results. Jeff

[@Abom79]

JRD77VET I always light it that way Jeff.

[@cfraley88]

What type of cutting fluid is that you were using in this video. Small can with a brush on your lathe.

[@lydck1]

Hey Adam! Do you think if it pulls a hard suction it will pull a vortex in the fluid? Just a thought!! Thanks for all your time you spend on your videos!!

[@sparkyprojects]

I think i would have started the bend a little sooner, then made a 45ish (or less) bend on the bottom while it would sit the way you have it, that would have raised it a little, and given you hand clearance while sitting parallel to the back of the gearbox. But the way you have it should work too ;)

[@gregkernick9073]

Hey Adam what was the brazing rod you used

[@WAVETUBE84]

Did the original hose show any signs of collapsing. Or a hole or leak: sucking air?

[@kb3nzq]

Where did you get the music for the end of your videos. I like it and would like a copy of it.

[@Abom79]

***** Most of my music is made by Silent Partner. All of there music is free to download straight from your Creators Studio.

[@timberk36]

Nice Job!!! What did you ever do with the poppet that showed it was leaking?

[@Abom79]

tim berk I wasn't convinced it was bad so I installed it to use as is. We will find out later if I was right or wrong.

[@w056007568]

Excellent suction tube replacement job Adam - vast improvement on what was there before! Frankly I'm surprised that the filter is as close to the surface of the oil reservoir as you appear to be suggesting -does your hydraulics expert or yourself see any possibility of air bubbles being sucked in when the machine is working due to oil draining back to the sump?

[@Abom79]

Dan Whiteford I have nothing to show the exact placement for the filter, or if K&T even put on on the machine. Many systems dont use one at all, just a line in the oil. I sure hope it works out fine.

[@experiencingtechnicaldiffi5184]

Abom79 I have repaired 2 K&T S12 that had similar problems with the feed and rapid traverse. Both of them had inlet screens like yours. One had a cracked inverted flare on the top of the inlet tube so I cut off 1/2 inch and reflared the tube. I did that through the access on the side, not easy. The other mill had a previous owner who thought all oils are the same so as the ways used up the oil he topped it up with used motor oil. Eventually it quit working so he sold it. I had to do a complete teardown (table, saddle, knee and power unit) to remove all the sludge. You can live with some internal leakage but if you were to test that flex line that was on the inlet you will find it was sucking air or collapsing, being intermittent and gradually getting worse. I love those machines. Probably the best mills ever made in that size range. I believe you're on the right track and will have a good running mill shortly so I expect to see lots of chips soon.

[@Abom79]

Moholo 88 interesting. Good to hear from someone who's been into these machines before. When you fixed ths feed problems was the inlet tube the only problem you found?

[@experiencingtechnicaldiffi5184]

Abom79 The one with the cracked tube when I opened the side cover the screen was laying on the bottom and would move when I touched it. I thought it was just loose until I took the fitting apart and saw the crack. Fixed that, did a lot of cleaning and refit the gibs. I used that mill for several years with no other troubles. The other mill got all new O-rings and seals because of the wear from the bad oil. It worked good but had a lot of wear on the ways so it eventually went to a machine rebuilder. I saw it later and it was like a new machine (and priced accordingly). An absolute joy to run. They didn't even open the knee. Testament to superior design. By the way, you need to take some square tubing and shafting and build a parking crane for the vertical head to keep it off the floor. They were an accessory that should have come with the head but were optional. About the third time I had to clean the chips and munge off AND use the hoist to pick it up I built one for each mill. There is a hole in the top of the machine just for that. It will save your time and back.

[@204052971]

Are those full flow fittings on the suction tube? BTW, that's a nice clean tube.

[@WAVETUBE84]

Maybe the suction hose was collapsing??? If the filter became clogged, or was just causing enough resistance, the suction tube "could" collapse. That is if it was a flexible line??? Does the electric motor turn the pump and the transmission gears for the shafts? The hydraulic system just for changing gears?

[@Landrew0]

Why not a flare-fitting instead of a silver-braze?

[@timr31908]

Love it just keep it in the oil..never have to clean it a life time.

[@royamberg9177]

Nice job on the pipe. Just a pointer on using a tube bender. If I can explain it so you can understand it. You don't use these benders to often I see. You put the line on the pipe correctly. Now when you place the pipe in the bender put the line looking at it from I call it the end there is a half circle to the round die Place the line ether to the inside of the half circle or to the pipe diameter away from the inside of the half circle . depending if you want the pipe to go over an object or inside an abject. This sounds confusing and it is if you don't use them daily . something I do when I silver solder. 15% for copper or 45% for steel when it soldered once the solder sets up and cools a bit I quench it with water to temper the pipe. Right or wrong I don't know done it this way for years. I do Refrigeration work and things vibrate it seems to help keep it from cracking .

[@pierresgarage2687]

Roy Amberg I've always been a little confused about positioning the pipe or the die, I'll look into your advice and practice a little... ;-)

[@royamberg9177]

Yes raw experience. I don't follow the instructions they give with the benders I'm in a hurry when I'm using them as the equipment is down and time is valuable . now it's a habit . I could draw my instructions a a paper and email is you'd like

[@pierresgarage2687]

That be great...!!! Just go to my channel, on the "About " section there my mailing address, thanks... ;-) (If you have any problem just get here again)

[@royamberg9177]

Can't find that email address

[@pierresgarage2687]

Roy Amberg Try this it should work [e-mail] I'll check why it doesn't work... ;-)

[@JimWhitaker]

"Snap" 😂🤦🏽‍♂️

[@Mr05sti]

I would of just mig welded that but that's extra insurance

[@pierresgarage2687]

Mr05sti This silver brazing is going nowhere.... !!!! Even with vibrations... ;-)

[@Mr05sti]

true but even with vibrations it can still break...

[@pierresgarage2687]

Mr05sti Probably not on or in the weld... :)

[@marceltimmers1290]

Hi mate. I could not stop talking at the screen. The only thing I would pay some attention to, is the wiring. The protection on them is not as good as it could be. I would hate it for you to get a short, when it's all back together. all the rest looks like a goer. Marcel.

[@Abom79]

Marcel Timmers I rewrapped the wires.

[@marceltimmers1290]

Abom79 Just at the moment I'm looking again, you putting the filter on. Thanks for the update it'll make me sleep a lot better.
