DIY Line Boring Tool
Вставка
- Опубліковано 3 бер 2014
- To get a really good O-Ring seal you need a close fit and Schedule 40 pipe can be out of round by as much as 20 thousandths of an inch ( 1/2 mm ). A line boring tool will cut the pipe nearly perfectly round and can face off the end as well.
Great video! We're looking at making a line boring setup so we can melt out the old babbitt and bore the holes for bushings for the tumbler shaft on the engine in our 40' steamboat. I love watching your videos. Keep it up!
At first I was trying to figure out why you weren't doing that on the lathe behind you then I saw the length of the tube that is very slick. You guys amaze me what a great job you all do together.
Both of you are truly an inspiration. Love the DIY/figure it out/git er done mantra that every project you tackle is flowing with. Keep up the good work!
Thanks for the good vibes.
Your ingenuity never ceases to amaze me.
Well done team!
Great video, I really enjoy following your projects, thanks.
thats excellent work
love the fit of the plug
now that is real art
One of those vice grip chain clamp tools would be perfect for holding the pipe to boring attachment.
Right on! Great way to get the job done!
very nice work there Doug
Amazing work! An idea to future projects is to use the piston rods of used shock absorbers, it's ease to get it free, in a workshop. Normally good material, and free...
Funny story for you, Years ago, my dad use to work for Hughes Helicopters (Pre Boeing days) as a Liaison engineer. They had taken delivery on a new, huge CNC, multi-head cutting tool that was about the size of a small shipping container and it had a robotic arm.
Anyway, after delivery, a couple reps from the company with the aid of a few Hughes employees got it set up but, it was missing one vital component, it's air conditioning system which was back ordered, and, it was a hot day inside this factory. After getting it started and programmed to run, it has been running about 20 minutes and due to the heat issues, the system went haywire and started selecting bits (which were large heavy items and "throwing" them across the plant. People were running for cover as these large bits smashed into walls and other machinery... luckily, no one was "KILLED"!.
Nice. I guess it was defending the big red button. :) I ran the database for the robotic parts system at the Boeing Apache plant. We never had that much fun.
Hi, Amazing job!! I've been a longtime subscriber and it's very motivating to see you folks clear these hurdles you come up too, watching channels like yours made me decide to start posting some of my own.
I do a fair amount of line boring and associated stuff, and it is really cool how your design is almost the same as a commercial unit, some of them even use a mag drill for the drive and feed, and they all use some type of self aligning bearings.
If I could make a couple of suggestions that wouldn't be too expensive and easy for you to do, instead of the hose clamps, maybe short lengths of chain that would be left too short and drawn up with threaded rod, and a really simple system to get the pipe mostly square and centered to the bar would be to turn a pair of tapered cones with a center hole the size of your boring bar, and then when you slide the clamps from each end of the pipe, it will kind of float and you can shim up to it.
If you would like, you can see a various line boring jobs on my channel being done on a commercial setup, but by no means a top shelf model, I think you can see me using the cones for lineup, I've tweeked that system a little and I'll be posting a video of that by the end of the week, including the line bore which was a bit tricky.
Again, awesome and inspiring work, and fun, which I believe is very important as well!
Thanks ...... Mike
Thanks Michael. And it great that you're sharing your work. The more stuff I have to borrow ideas from the better! And thanks for the tips too.
This is a great episode
pretty amazing.
Nice shop!, one day maybe ? I would love to have it .
great field tooling!!! works well
Hi I have seen all your movies in two weeks it's just an exciting book. I hoop to see many more videos of you.
Regards Rob de Bock Nieuw Vennep Holland.
the tool you guys made for the boring head looks a lot like the broaches I make, except I have to relieve the sides of the cutting facefor broaching a square slot.
using the shims and the angle iron was a great idea to square up the ends. You made it look easy. Back when I was making my camera housings from pvc, I used a wood box on top of a router and turned the pipe inside the box by hand over the router bit to even up the ends. and put the o ring groove in them too. It was sweet to see how nice the end cap fit, you guys do amazing work. somebody told me once that if you have the right tools, enough time, and a big easy chair to sit in and try to figure out what you did wrong, you can make anything.
Routers are wonderful tools in the right hands and dangerous as hell in mine. I was cutting a hole in aluminum one day when the router kicked back and I lost my grip. It continued to run and bounce around and spin. I almost decided to reach in and try to grab it but then had the bright idea to just unplug it. I almost got it unplugged about the time it cut it's own cord and started a welding process. :)
That is a good fit....pro job guys, when can we see you back at the battleship?
+ SV Seeker you should weld ears on the edge of you angle, the cut a 2 ft section of angle with ears and pinch the tube between the two angle sections. Like a V block
Very good common sense tool making. Enjoyed your video. A few have pointed out of course you could have achieved the same task easier on your lathe but what they're failing to see is that you have made a tool that can be taken into the field for repair and prototyping where machine shop equipt is not available. Genius. I'm sure you've already thought of it but I thought I'd mention if you have harmonic vibration problems on your stock in the field, you can wrap the stock with a cut up inner tube or something else made from rubber to absorb the harmonics during turning to ensure a smooth work surface. Chris B.
That's correct and thanks for the tips.
You can't do it on the lathe if the tube is longer than the lathe can handle though. I really enjoyed the video. I would take some time to refine the holding system. I'm all about making jigs and fixtures and making them micro-adjustable whenever there's a need for it. In this case maybe "micro" isn't necessary but something solid and adjustable would save you a lot of hassle and frustration if you're going to be making a lot of these things. Great work!
And all this begins with John Wilkinson in 1775. First boring machine. Great man Sir Wilkinson.
I know this video is pretty old.. But have you thought about drilling and taping some holes in the angle iron to insert bolts to use in stead of the shim stock? you will be able to adjust the pipe up and down as well as side to side. And and as for clamping the tube. maybe some swing over jointed straps (3/8 thick)also with threaded holes for bolts to clamp and adjust up and down .
I can't reply to your response message for some reason but yes and no if you steady rest and do a finishing cut on the OD then adjust the steady rest to that section and finish out the OD then move onto the ID. This way you have matching ID and OD depending on how long it needed to be.
Btw love the channel. Wish I could take part in a big project like you guys.
Right, that makes sense. Thanks
Years ago I use to use varsol as cutting fluid for aluminum. While it was set up for cutting the diameter the facing and 20deg bevel should have been done at the same time. Half of the work can just be setups.
Nice work guys. :)
This is a neat little jig, but I have to wonder why not the lathe? Take the tailstock off and mount the pipe on the compound. Then just chuck up the boring head in the 4 jaw. A steady rest, if big enough, would be a bonus.
Greetings from New Jersey
You're the type of people I would want in my foxhole if the time ever comes.....nice job!
Thanks! That's a great compliment.
Looks like a rock concert with the flashing light!
A nice piece of work and it does the job you want it to. To me though, that is not line boring. but boring. Line boring is where a series of bores are machined on one axis, with the boring bar supported either side of the work, e.g. the main bearings on an engine block.
That’s fun the little kid in the back ground playing with the setting on the welder I think. Good place for the little guy to get in trouble. Lol
Amazing what you can do in your shop!
Thanks. It's great having a heated shop. The last one had a good roof, but the walls barely slowed the wind down.
Wow, this really inspires me. I'm in the process of trying to make my own offset boring bar, not the actual cutting tool but the holder at least, to see if I can cut a quite precise hole (I'm okay with anything up to 10/1000 tolerance) in a piece of plate aluminium. Don't know if it's possible or if I should just pony up the cost of an offset boring bar. Time will tell!
Thanks for the video! Subscribed for future stuff!
Cheers!
/Daniel
you get can get cheap boring bars that do an awesome job and prob better than most guys can make at home and youll be happy and confident in the results, coming from a toolmaker ofcourse
Benjamin Harris Wouldn't you also need a lathe that could turn the largest pipe section to be bored?
in relationship to?? plate?? nah, ive made a few boring bars and after all the time and effort IMO you can easily get a 2nd hand one for a reasonable price plus i think this guy wants to use in a drill attachment from what i gathered
Benjamin Harris I may not be a tool maker, but I've made my fair share of tooling for my own purposes before. While the comment was made 5 months ago, and a lot of things have gotten in between, I haven't given up on this idea. I'm no stranger to making things to fine tolerances, so I don't expect this to be an extremely hard project. You can check out my channel for some examples of the stuff I've made thus far.
I wouldn't put it in a drill of any sort, but rather in a proper milling machine.
good stuff! thanks!
Very nice, It is cool to see the gadgets you come up with to solve a problem A+ for thinking outside the box.. Take care
Thanks, Super Dave gets the credit for that one!
Not necessarily too fast feed; the tool needed more relief. And that's jig-boring since the tool is unsupported on two sides! At 8:10 nice fit, hydrostatic film of air permits it to bounce like an air hockey puck ~ nice ~
Use motorcycle or bicycle chain instead of hose clamp. At 10:55, single point clamping will deform the tube when it's boring, so it will not come out truly round (this is a field of its own in cnc workholding).
Tool gumming up -> put more tool rake ( 15 deg) , 15 deg relief too. Add rake by grinding a groove in the tool (chipbreaker). Alumitap is excellent for all aluminium machining. Ethanol too, if you ever run out.
Thanks for the tips. Yes, one of those chain pipe clamps would be perfect, I'll need to expand my inventory.
I think you can just get adapters to fit regular bike chains, or make one and save money that way!
meocats Thanks, but they are only $18. Someone should start a video series of building everything only using tools they have made. Starting with an earth furnace and working their way up to a lathe and mill powered by a water wheel and then a steam engine. That would be epic. Call it "Raw Metal". I nominate you.
Would this work for boreing out ls cam Bering journals maby build a metal adapter plate that the mag drill attaches to??
Well done Sir....
Cool tool! Kudos to superDave (and you) for that one! Although I always thought 'line boring' meant the tool shaft went completely thru the work, supported at both ends. (there I go thinking again) I guess if everything is aligned properly, it'll work. :)
I've been using that style deburr tool for years. The only thing I don't like about them is their occasional tendency to "hang" and make gouges rather than smoothing the edge.
I see the winch is holding up nicely to the weather. (gotta love those ancient epoxies!) :)) Still waiting for the next spool casting vid. :P
Thanks. Yeah, someday with the spools. We keep moving the block molds around the shop to try and get them out of our way. Casting them would solve that problem. :)
Bravo come sempre!
Nice work done out of a specialised shop. In order to hold the pipe in your jig, do you have access to those Vise Grip using a chain ( like those for a motcycle) ?
remige2006 I do now, and that is what I have been using.
hi i have watch numerous of your videos i am very fond of what you guys are doing i would love to do the same but too young and harder in europe i hope that you success on this long journey and keep making those awesome videos
Harder in Europe? I've seen lots of great building going on in Europe. What's harder?
the fact that i live in paris and that i found the materials and the price was pretty expensive and i am maybe too young for the moment but i hope on day i can build one a litttle smaller than yours but i was wondering if there was a different way than origami and how how would it be to do it with aluminum?
EaZyIAYM Yes, aluminum works fine in origami. We almost went that route with our boat. The only thing I don't like about aluminum is how easy it is to gouge.
Awesome, I have the same mag drill and was thinking when I got it that I'd love to make it into a makeshift line borer.
Nice job the end cap looks like it fits really well. You may want a bit more chamfer on the inside edge of the pipe to make the plug go in easier when you have the o-rings installed.
You're going to spoil the next video Bill! But we actually can not chamfer the pipe because it would not leave enough material to support the 3.15 * (2^2) @ 2000 psi = 12.6 tons of force that will push the pipe against the bulkhead. So we are using a hose clamp to compress the O-Ring like you compress piston rings in order to slide the O-ring into the pipe. Works like a charm.
Very nice work. A question, instead of shims how about set screws in the angle iron, 2 on the horizontal and 2 on the vertical, that would hopefully allow a more fixed set up that would need only minor adjustment to each screws to accommodate the variations of each new work piece. Would that be helpful at all?
I don't think the pipe is going to vary that much, but the set screws are a great idea if a lot of changes to the adjustment would be needed.
Nice boring jig!
Doug & Kay,
For about $10K you can get a lathe that has a 3.15" spindle bore:)
Kidding aside, you could try Kant Twist clamps. The other thing that might make this easier is to have the angle stock that holds the pipe mounted separately and some adjusting screws. If this is a one or two off, very clever solution!
Good show! Pretty neatHuhu!
potrzeba matką wynalazków - proste wytaczadło własnego pomysłu a jaką profesjonalną pracę wykonało 👍
If you don't have a mag drill and a hand drill doesn't have enough control, I bet you could mount the tool to a drill press. It would probably be easier to lay the drill press on its side or back than to try to mount it vertically, but I'm sure either could be made to work.
Awesome video man!
Thanks
use T bolt clamps like on a air to air induction system on a cat motor . They are like a hose clamp but stronger they use nut and bolt basically to tighten the band and they shouldn't strip out and they are made of heavier material hope this helps
Right, T both clamps would be good. I have some, but they were too small.
Is your lathe not long enough to use a steady rest and boring bar? That way you could align the shoulder to the center cut. You could even make a steady rest simply enough.
Not long enough, and the steady rest is too small, but even with a larger steady rest wouldn't the fact that the pipe is always out of round cause a problem?
Nice build and video, but I'm wondering why use this instead of your lathe in the background? Wouldn't that be easier?
finster101 Too big for it and I want something that can be used in the field.
SV Seeker Ok, that makes sense. Thanks for the reply, I appreciate it especially on an older video like this.
Another option instead of shim would be to drill and tap a hole in the angle iron on side and bottom and thread through a bolt backed up by a jam nut. You could have really fine adjustment and put 2 or 3 throughout the length of the part. This would negate the spring effect of stacked shims
where can I buy the boring tool
hello a question that means DIY and I read almost all the videos thanks
Do-It-Yourself ...and thank you.
What kind of bearings did u use...kindly share model/make. Did u ever check the run out of the shaft between the bearings during cuts ?
They are self aligning but nothing special. I think I got them from Surplus Center: www.surpluscenter.com/Bearings/ And I did not measure the runout but we got parts round to within a few thousands.
Cool video!
You're thinking steam engine cylinders! :)
SV Seeker Yep
were did you find a small adjustable boring head like that? it must have a left hand tread or something to connect it to the shaft, all line boring I have seen working in bush camps as a welder, the parts or pin bosses of say a boom pedestal are always between the 2 bearings, not out past the 2 bearings, I know I always had to weld the bearing plates that the bearings were bolted to. had to tack weld them plates to ether side of the bushings being line bored, the cutter head was on a really fine threaded shaft, and as the 1/3rd hp motor turned the shaft, witch was belt driven, the cutter would slowly move down though the pin bosses at each side of the boom ears after I welding in the new pin bosses. many machinists that came to the camps had home made line boring, made from a washing machine motor and transmission, they would rattle a way like mad, but made a really nice job.
We got that one from: www.wttool.com/ ...then Dave threaded the bar to replace the little bar that came with the head. And it' just standard threads.
Thanks

Really great.
I'm looking at your picture I wanted to make boat.
I am studying to be a few years ship.
I direct ship ever built, and I would like to sail the sea.
Get to work, We will meet you in Hawaii. :)
I love the low voltage warning system, I thought I was the only one. lol
We have an electric instant water heater so I always know when Kay is doing laundry or taking a bath. :) And Dave and I were running 3 electric heaters, the CNC table, the bandsaw, and the mag drill.
There's been several times where I've kill the circuit breaker run the air arc. lol I thought another idea from your clamp system would be a large truck exhaust clamp they work great.
SV Seeker
hahahaa - a few times a year I'll be in the shop Tig welding and blow the feeder panel in the house - now I'm sitting in the dark with the hood on trying to find the door. The shop really needs its own service.
Every shop needs a dawg.
pretty good way to solve the problem cant think of a way to have done it an eazier way without some fancy machinework to make custom clamps and using way to mush cash and time to make it for the use its getting
you think this accurate enough to bore and engine?
+dantheman1998 No. I seriously doubt it.
8:07, insane
For facing could have taken small increment cuts.
I want to come up and work on the boat :)
Awesome! Drop me a line at svseeker@ymail.com and tell me what you need to know.
That boy is so cute！！
"To a person who always FINDS a Solution ..." What would be a way -> 2 opposite pointing Forces...giving 1 (constant pointing) OUTPUT?
+a Boswell Inniss A wedge?
A+ for effort, but you could do this in the small lathe that you have. Put the boring head in the lathe chuck. Make your V-block fixture, angle iron, whatever; and affix it to the cross slide (take the compound slide off). Then you can use the carriage to move the tube in and out from the spindle to bore it, and adjust the cross slide to center it or face with. Shim the fixture for height when you set it up. This is all very possible in your existing lathe. Not bashing your efforts in any way, just saying the lathe was right there and would be easier to set up, and cut better. -Doozer
We considered that, just didn't come to the same conclusion.
But if I ever have to bore something in place, like backhoe pins or something, I will copy the kind of setup you made, because it seemed to work very well.
To quote the wise words of keith fenner "I'm happy with that"
Mine would be "I can live with that." :)
lower RPM ...but I like it
should have saved yourself some time and put the boring head in the chuck of the lathe and take off the tale stock,
mounting your angle iron and pipe where the tool post goes. I have done it before with off center holes on pieces to big for my 4 jaw too.

Have you crush tested that AL pipe yet? Humm....that could be a spoiler.
Not yet, but the crush psi is suppose to be almost 3000 psi. www.sapagroup.com/pages/522736/Brochures/Sapa%20Pipe%20and%20TubeTechnical%20Inserts%20June%202011.pdf
love your videos svseeker but for all thoes who dont know DO NOT WELD with out gloves you will damage your sking or burn your self Hes a bad ass dont try that at home
+victormendoza871 If you weld you do what you do !!! Safety my ass.
Take that job to any machine shop, get it done in 1/20th the time for 10% the money !!
And learn nothing.
You know . I went to college for Manual data input (for gcode on cnc) , blueprint design and construction , Computer aided design and computer aided manufacturing.
Point being I have a few certificates and degrees in machining. I can make parts with the best of them I would like to think.
I dont know how to cut threads manually on a lathe. I own a manual lathe also but no clue on how to cut threads. Crazy huh?
Good on ya. Treading is not hard. Most of the job is done setting up the machine. Check out videos by mrpete222 MACHINE SHOP TIPS #24 Acme Threading Part 1 tubalcain
SV Seeker
I know there plenty of how to but CNC makes it .... me lazy :)
You videos are great . I love watching them . Thank you for taking the time to film them. Whens that boat going to be on the water?
Mark,
What will make you NOT lazy (and how to learn to do things like threads on a manual) is learn to build a Live Steam locomotive from just plans. I now, I'm a CNC machinist on Okumas and Nakamuras. But my lathe at my basement home workshop is a 1957 South Bend model 9 A. bench lathe
John Tee
I did my first manual threading operation after this post. Really wasn't hard.
I think changing the gears out and grinding the correct hss tip was more complicated than the operation.
Mark Rich
perhaps you ought to try internal threading, internal grooving, move on to using the taper attachment, then after that maybe some line boring. Actually certain types of gears can be made on a lathe, did you know that?
a grand kid in the shop.who 20 yrs from.now will be sayn shit wish i had of paid more attention to grandad granny etc
The boring head does allow for precision but my thought is that precision is lost with that setup.
i have used a ratchet strap on a pipe to angle iron before which worked great. the way i did it was not to use the provided hooks. instead i put the tail through like normal and brought it around object then put the tail back through the rachet. so you end up with two pieces of webbing in the rachet. this way i am using the ratchet as a evenly disturbed band clamp of approximately 300 psi. this also works great when pulling pipe together to make a welded taper. also sometimes its advantageous to slip the hook under the ratchet hook under the band so the rachet doesn't flop around. this also works with the trucker rachet straps that are well over 1000 lbs test to make a wide high tensile strength band strap for less than $100 each and easily found.
hope this helps...
i would have done this on the lathe because you can make the head also statoniarie on the dril holder en let the pipe spin in the chuck excuse my bad english hahah
I would do it on a lathe too, if I had a bigger lathe. :)
