I build shredders and sometimes have to sharpen the cutter head. When we sand the blade, we make sure the curvature of the cutting edge is flush with the cutter bar. It is amazing how many thousands of an inch the metal expands from sanding. So you do have to walk away and let it cool down and then check. Good job letting people know about that last cut.
.001" per 100 degrees Fahrenheit will keep you in the ball park. You know you stepped in it real good when drawings call out a temperature range with the tolerance specification.
First time watcher, novice machinist/farmer. Just wondering, why wouldn't those saddle bores be undersized, then heated to install (frozen) shrunk pins if future wear was a problem with "so-called" loose fit pin installed. Your bores seemed more appropriate for the "dogbone" and a spinning shaft rather than a stationary pin. Thanks for sharing
Very nice.. you and Curtis from cutting edge engineering... makes me very entertained and happy... and it's about real work not that constant sponsored shite.. 😉🙂👍
That is a nice setup, turned out very good. Years ago I worked at a shop where we had to weld them up by hand because we didn't have the welder setup, we just had a guy come with the line boring machine. His was hydraulic as well. Keep smilin
My experience with insert holder's when lineboring is that the inserts don't have enough relief when cutting off center,but if you take a cutoff wheel and cut the head off and drop it down where the insert is actually cutting center of bore and I usually tig weld it back on carefully making sure it's straight made a world of difference for me..hss has its place for me its roughing out weld to keep my inserts nice as long as possible
Goodnight friend. I live in Brazil. I am developing a field machining tool. I would like to know the clearance that exists between the shaft and the bearings of the support bearings?? Today the clearance of my current axis is 0.05mm, I believe it could be greater, to facilitate assembly.
So how you start the bore welder on the edge of the hole is as follows. You shut off the step feature in the control panel. You start at 12 o’clock and weld counterclockwise down to 6 o’clock and stop. You manually put your welder back up at 12 o’clock make it rotate clockwise now hit start and turn back on the automatic step feature, it will weld from 12 o’clock all the way down to 6 o’clock and right about that point it should step back and keep going. This wayThe second pass has a little corner to fit into on the uphill side and you won’t get all of those dingleberries. Of course this requires you knowing what position the welder steps back in. Mine steps back in about the 6 o’clock position looking in the hole. If your welder does not step back at 12 o’clock or 6 o’clock you were going to want to adjust that so it does.
Not sure what the costs are near you but PG&E wanted a mint for 3 phase near me and it only have to go ~1500 feet. For less money you can usually get a 3 phase solar inverter (like Sol Ark or EG4) to create 3 phase. might work in your situation depending on the cost
Nice job. would a mig pulse device be better suited for bore welding? Then the weld pool solidifies faster and there is less chance of dripping when welding on edges... was i thinking
Very cool! That line borer is a beast. I've seen Cutting Edge Engineering Australia line bore tons of times but your rig blows his away. New shop tour coming soon? 😎
Awesome content. Love the channel. Also long time CEE subscriber and live just 100 miles from their Goldcoast workshop. Hey, if you didn't have the bore welder, would you manually weld it or press a bushing?
Great setup, also with the one side cutting and the other welding! If the mounting holes for the cutters would be spaced more narrow, you could easily setup two or more cutters in different cutting depths, following each other, but I guess that much holes would weaken the cutting bar... Thx for showing! 👍👍👍
On paper it looks good. In practice it is too many moving pieces. Battling deflection, harmonics, depth of cut. The estimated time savings erodes very quickly.
Hey brother, not trying to be nosy but how long have you been in business? Asking about of admiration I’m 25 and just recently started my own company while still having a full time welding job. You definitely have my dream job. I really respect where you have made it to.
only a mechanical engineer like me would make them two slightly different sizes to drive tradesmen like you crazy. your welcome. question. when setting up to line bore, if you can't find square with your setup shown.. what is your next best method? keep up the great work
Wishing the clams on the skidsteer I run only had that unacceptable amount of play. The bores in the clams seem to go bad real quick no matter what we've done, so we just pretend it's fine. Somewhere around 1/4-3/8" ovaling of the holes at this point. New machines on order(this one has 14k+hrs), due next year, and then this one will either become a backup or retired(we also have the old machine from another division coming in as a backup in the meantime)
A fair few years ago. I was running an onsite Repair business for different Earth Moving companies. It was going really well. I even got that busy I decided to sell off part of my business to another guy I worked with previously. Everything was going really well. We were both super busy especially with Line Boring work. A few other guys found out how good our business was becoming and started trying to get some of our work. We were a little concerned at first because they were using our prices to undercut us ???? Of course this did make a difference, especially when we turned up to do work for previous customers who got us confused with other guys who were competing against us ?? Occasionally mild arguments started over the confusion ??? Blaming us for putting the price up ?? Ironically, as time went on these cheaper guys either stopped doing the work or started hiring people to do the work. Eventually the quality dropped off, and in some cases even we got blamed for the poor quality of work. I always made a habit of stamping my work to lessen the chance of any come back from the confusion. It got to the point of being called out on jobs because of our competitors ?? Having to drive to different sites to inspect the work to make sure it was our work they were complaining about ?? In the end I basically had enough of all the Bullshit and sold my equipment, I didn't bother trying to sell it as a running business I simply had enough. My partner kept going for a few more weeks to finish up work that we had already been booked in. After that he basically did the same as me and sold everything to different guys who were willing to give it a go. He did have thoughts of trying to keep the business running. But, in those last few weeks he was starting to be called out to the same Bullshit as I was dealing with previously ????
I run the same set up. Just a tip you can try w the bore welder to save having to come back and hand weld the starting end of your welded bore....ring the edge of the bore w the bore welder down hill like this, start at rot. int. weld from there to 6 o clock, stop weld. Rot. Jog to 12 o clock, function and rotate jog buttons at the same time to reverse direction. Weld 12 to 6 o clock and tie into previous. Rotate jog back to 12 and reverse direction again, weld 12 o clock to rotate initiate and it will step and continue as usual, makes for a very clean edge and first wraps going up hill.
Those Climax universal mounts are pretty nice eh? I have had a Climax bar for 25+ years. Hauling that 8 foot bar around is fun. Try a 10 footer! The Climax Hydraulic power packs have improved greatly in recent years. Mine is a modified industrial Dynex-Rivett 5HP unit that works great, but not good on low flow due to my flow divider I used. Anyway I like your set up very much. Cheers.
I found when you start welding if you can run a pass from 12 o’clock to 6 o’clock and then from 12 o’clock to 6 o’clock on the other side of the bore it gives you a shelf to build up your weld against. Thought it might help.
I'd like to know more about that hydraulic drive motor. Is it running a worm gear that turns a captured collar? That would explain why there is no slowing it down. Something would break in a bad bad way first.
You have got a great skill set, you can do alote of different things start to finish. i enjoy learning things like this and your explanation. Hope you charge accordingly I also am self employed I would not change a thing but long hours do take a toll along with wearing many hats
Depends on your current skills. If you already know machining and welding, about 100 hours. If zero experience a couple years. I have done hundreds of setups and I always run into something different. You need to be really good at improvising.
@@OFW i have been welding for 5 years so far. But I was introduced to training in line boring by my superiors. I’ll be training with an experienced line borer for 8 months. We have the BB4500 model.
1980 a farm tractor front end the center was all worn out, badly, took it to the machine shop & went back 2-3 days later, it was done don’t know how they did it but it was done
Awesome video very informative. Couple more questions.. what kind of work angle do you have to use with the cutter tip? When you faced the outside of the boss the flat part of the tip looked parallel to the face. When you are inside the boss do you cut with the point of the tip or flat edge against the wall? Don’t know if that makes sense. Also prob been asked before but could you run the hydraulic motor off the PTO of the KW? The setup you have looks heavy duty as could be but just curious.
I would say the cutter runs square to the bore. But you could use others that are not. I have thought about running it off the KW but there is a lot more to it than just getting hydraulic pressure.
@@OFW I guess what caught my eye with climax, was it seems like its the most compact yet powerfull machine when you go hydraulic, the accessories seem the best, i love the bearing housings with the adjusters. idk seems like it would all pay off.
@@eesllcin my opinion Climax is the best system. It is the most compact and they offer the most options. They will even customize anything for you. Their customer service is great as well. But it will cost you a lot more than any of system.
@@OFW I was curious because the surfaces that those alignment cones were set into did not look perfectly square. I could see how the top pin would be aligned in it's holes, and the bottom two pins with those four holes , but not sure how the top and bottom pins were aligned with each other.
How do you plan on addressing the machining? Interrupted cut on Rockwell 58-60 is not pleasant. I see a pile of broken inserts in your future. Nobody hardens those features for good reason.
@@ShainAndrews well at least a hardened steel insert should have been employed from the beginning! As far as r c. 68-72 sometimes doing things right takes a bit longer. If it was a job for me I 'd takes the extra time.
