Your little line boring machine is a clever, workable solution to your needs. You'll be modifying it for as long as you use it, it's never going to be "perfect", and there's not a thing wrong with that. The steadfast attitude you display toward problems arising is great! I don't know why your channel was recommended to me, but I'm thankful. Easy choice to subscribe.
This reminds me of the cheap 1960 Case backhoe I bought once. I couldn't afford anything more expensive. I lived with it for over 20 years, while I fixed almost everything on it. It looked like it had fallen off a trailer at high speed, or had a big accident, because everything that moved was cut off and rewelded. It was a mess. But it delivered miracles over the years. All in all a true pain in the ass.
That is awesome. I put a $500 downpayment on a Fordson Backhoe and I was run over on my antique Harley. I will not be able to make the 3 more $500 payments now so I have to call the guy and tell him in a couple days. It really sucks.
Very nice job. Your line boring set up is so smart. I noticed you feed manually. I remember enjoying your trebuchet videos and the good interactions with your grandpa.
Awesome machine. Grandfathers find the best stuff. I wish mine were still around. You can find some great things at auctions. Thanks for making this video. I am starting a small engine , mobile welding and custom fab business and really enjoy watching yours. Those welds were definitely from another time. I never came across anything that was hardened like that. Great job getting through that.
Reminds me of the "Goodson" machine at the engine machine shop, when I was a kid. Great idea with the hyd. Motor and power pack, thanks Grandpa! Really enjoyed it.
Working in some tight spots, line boring machine sure does a nice job. Can't beat the arc of an old Pipe-liner for smoothness, that little inverter never will. Most of them do a pretty good job if you use a rod they like. I will have to look back and see if there are some other videos on this earth mover, for some reason I am not getting notifications. I will check on that. Take Care and Stay Safe Bob
The first video is linked in the description, and at the end of this video, just in case you're having trouble finding it. Yeah, I've been hesitant to get a little inverter welder as I figured they weren't much good, but a customer had it and asked if I'd trade my labor on his repair for it. It welds nice with 7014, not so much with 7018, but given it's small size and ease to move around, it's a handy little thing! It also has TIG and Plasma cut built in. Pretty neat little unit.
If you make the support for your boring motor straddle the axis the support won't torque away. Or you could put 4 supports. But like you said, work in progress. Thank you for posting. My welding truck has a PTO hydraulic pump and hose reals on the back to drive hydraulic tooling. 250 hp hydraulic drive system ;o)
That was a neat line borer WIP is pretty normal for tools you need to use NOW. Spent way too much time machining stuff that was welded without pre or post heating. I didn't know at the time but found out since, most carbide tools are only designed to cut around 65 Rockwell material (or softer) and 'hard spots' in welded material can be above 65 Rockwell hardness. I'm actually glad I don't work on construction equipment any more.
Good video. First one if seen of yours and you have a new subscriber. You're sharp with a get er done with what ya brung attitude that hits home with me. Thank you for sharing it and I'll be doing some catching up watching your other videos and any new ones you make.
nice simple little setup you're got for line boring. one thing that could make life easier is to drill and tap 2 holes in one of your bar clamps for pushing the cones into place. we have done that at work and it makes all the difference when work by yourself. The only side note is to use SHCS as a regular hex head will need too much clearance to use. keep up the good work.
... Points of Reference (for where the finished bore 'should' be) in-the-field are called "Sky Hooks" - skilled hands make 'em.... Great Job tooSavvy @Lockdown UK
I hope it helps. If you'd like a little more information, I also have a video series (they are long videos, and I think they are titled "Tractor Axle Line Bore") on line boring a front axle on a 2290 Case tractor and a video (a single video) on line boring with a slightly different setup on a loader bucket pin on my 1370 Case tractor. I think it's titled "Loader Pin Repair." Good luck with your project!
Well done Matthew that is no easy job. Line boring takes time even with an expensive set up so kudos on that. I assume you were using 7018 to weld your bushings in. I know it seems like some inverter machines don’t weld good but that’s odd on 7018 most of them do really well. Maybe it was just my ear but I I could’ve swore the way it sounded like it was on the wrong polarity, but it’s hard to tell I’m sure your bushings will be just fine though Press fit as hard to move especially with the weld on them lol. Going to be a nice piece of equipment though I’ve ran dirt pan myself and then things can move mountains.
I did use 7018 on the bushings and Somebody else mentioned they thought the polarity was reversed. I plugged in the leads according to the labels on the front of the machine, but maybe they aren't labeled correctly?? But now y'all have me thinking I better check it with my multimeter!
Nice job, I used to works an inside machinist for a ship yard. We line bored stern gates with a tool just about like yours. Slow and easy with the feed. We would have the welders add material on the wire side to keep the bore where it belonged.
Great job! Nice home made boring bar. Looks like it works pretty good. The only thing going to a large dia drill like your 7/8 right off the hop is the web area of that large a drill is blunt for drilling. Even something like a 1/4 or 3/8 pilot drill it will make for a much eazier large hole to drill. It did work out for you but posting this to show others a more proper way to drill large holes. Nice work all around!
Lol, I really thought the bushings only got welded in, not such a precise press fit, that was my plan to help out my neighbor anyway. Got to rethink this.
Nice work Matthew. I like the homemade line borer. If I end up getting a bunch of torn up farm equipment to repair I may have to build something like that.
for cone set up. get a bolt big enough you can drill thru it to the cutting bar size.. drill thru the flats on the top for allen set screws to lock it to the cutting bar.. use a nut on the threads to push against the cones.. you may want to drill holes in the flats to allow you to use a 6" rod like winding a garage door roll up spring to tighten the cones in position by using the rod to tighten the nut.. may have to drill next to the holes for the set screws on the bolt head for pins also.. try to get a fine thread bolt and nut. be sure to use dog tip (Blunt and thread relieved) allen screws so you don't mar the boring bar as you tighten the 3 allen screws in the head of the bolt.. free hand with your 1/4" die grinder a relief in the original oval bore to allow your cones to center where you want them to also works..
Like your final reference to 'Hitchikers Guide to the Galaxy', the radio episodes were the best! Particularly the 'precognitive elevator (lift)' which tried to persuade it's passengers not to go up.
Nice job on the home made line boring machine! I was wondering if possibly that hole hadn't been worn out to about 3 inches and filled back in with weld where it looked rough.
Bravo on boring machine .......love it ......im thinkn of building a mini lathe......have u tryed carbide cutter.......u running 6011ac or 7018dc negative ....cheers
@@WideVisionMetalFab I was restoring a hydraulic power pack for pressure testing cylinders on my back hoe, when I came across your video. Would you know what the gpm is on yours? Seems like a perfect setup for that line boring.
@@FFLFFS 10:30 in the video I explain it. It's advertised at 1 gpm but the hydraulic motor's RPM on my line boring machine is too slow for 1 gpm. I think the unit is actually producing something like .75 GPM.
Well, he still step drilled, he just took big steps. I know that I should still to final size on my lathe at work but that cheesey Taiwan tailstock can't hold enough force to drill in one pass. And it is a 16x60 machine.
Super nice line bore machine you got there. I´m fascinated of this process and often wanted to make something like yours. The feed mechanism has always puzzled me so the closeup was much appreciated. The ones i´ve seen use an electric motor with higher speed and make lighter cuts as in a lathe. You can do it in one pass? Beautiful lathe, aswell. Looks like the one Dave Mathews Steam Power Machine Shop uses. What clearence bored hole to bushing? You sir, are a pro! Greetings from Sweden.
The "feed mechanism" for my machine is the screw clamp from an abrasive chop saw. I did try to do the entire bore in one pass, but didn't have enough power. I think I made 4 passes? I usually press fit the bores about 0.004 of an inch. (Roughly 0.1 MM?) My lathe is an old Rockford brand from the 1920's. It's a wonderful machine! Thanks for the kind words! :)
Missed your comment somehow! It's a Temco 30 ton Hollow Ram with a hand pump. I ran a threaded rod through the bushing and through the middle of the ram. I hope that helps. :)
I'm finding this really interesting and I subscribed to your channel. Just curious though: This is sorta a specialized piece of equipment, isn't it? I mean not even a lot of digging/land maintenance companies own or use scrapers these days. When I think of scrapers I think of a fleet of them working on an earthen damn project or something similar. So, I'm wondering what your plans are for this machine once you are done (if you don't mind sharing). Sorry if you already explained this in a previous video already because in that case I missed it. Thanks!
I really didn't explain it. I should add that in at the beginning of the next video. The customer is going to dig a pond on his property. This was the cheapest route he could go, and I think he'll have a heck of nice piece of equipment in the end. Scrapers are really common around here. All the road departments use them and a lot of farmers use them to level out their fields.
Really awesome job. Love the boring rig. Cool hydraulic motor. One question, why is your lathe so loud? Something has to be rubbing or loose or something.
Somebody converted it from the flat belt drive to a ring gear and jack shaft drive. They pressed a couple ring gears on over the flat belt pulleys, so it literally rings like a bell. Plus the jack shaft runs in old wore out Babbot bearings, which adds to the noise. It's on my list to put back to flat belt drive.

Is that a HSS bit or Carbide? If HSS it’s doing a great job in that weld hardened casting. All very interesting and thanks for sharing. Tasmania 42 South. 👍🛠🇦🇺🦘
My father forced me off the family farm about 3 years ago. My wife and I had to quit running cattle, bought a house in town and we're running the fabrication business out of the little garage until we can find something better.

It's cable/winch operated and I'm switching it to Hydraulic cylinders. There's another video on building the front cylinder mounts which explains it better. The video on the rear cylinder is coming soon, I hope! Just trying to finish the edit on it.
