In this video from our workshop we are making 5 sets of tailgate brackets for Caterpillar 785 Mining dump trucks. The brackets will be mounted underneath the body of the dump truck and will help to open the tailgate. We are using high tensile steel plate and need to do plenty of machining, gas cutting, milling and drilling to complete the brackets for our customer. We start with boring the plates in our LZMT lathe before using our UniMig straight line gas cutter and to cut the plates in half. We then use our milling machine and 45 degree face cutter to mill the surface of the top plates. After the facing is complete we use an annular cutter to drill the bolt holes into the top plate. We then complete the brackets by use our radial arm drill for drilling the bolt holes into the base plates.

In this video we are using:
- LZMT CW6280D Lathe
- UniMig CG30 Straight Line gas cutting machine
- BM-63VE Milling machine
- Hafco ZX3050X16 Radial Arm Drill

IMHO: Drilling the holes before cutting in half would have provided match-drilled holes without a lot of additional setup.

Another great video, quality content, just out of interest, why did you not mill to the top of the larger piece like you did with the cap ????

Just a quick question. You used the slugger on the caps and switched to a traditional bit for the bases. Any reason to not use same bit? Price of slugger vs standard but I suppose?

Oxy-Acet (or propane/MAPP) still the best for steel plate...! I've done tons of this stuff, many tons. Plasma just doesn't do the job on 6" plate...

I'd love to see some "stats" posted on some of your jobs. This would have been a good one, since you had so many changes to do. I'd love to know what the average set up time for each piece was, as well as the "working" time. When you do welding jobs, I'd find it interesting to know how many meters of wire you used for each weld as well as the entire job. I'd also love to know how may KILOMETERS of wire you use each year! :-)

I don’t know how you guys come up with the variety of content that you do - it’s bloody amazing and always without fail a learning experience - I don’t think you realise the level of skill you’re imparting to those of us who are learning the trade (very late as I’m over sixty) in some other countries you would be titled a “master” machinist I imagine youd be in charge of other machinist and lots of apprentices - your generosity and no bullshit approach to the work is as Aussie as it gets. Cheers.

@Bretty Eleven Good thing is, that the machines n the apprentice shop got a kid of Ripcord Emercency Switch. One end was to Clip on your belt, the other side was a simple pin in a stopswitch on the machine. If the operator moved more tha 1,5 meters away, the machine stopps.

40 Minutes overdose of CEE, love you guys! I’ll appreciate it so much that Kurtis is showing all this. I’m driving such machines all day, and to look up how big repairs are done is just great. I would even love it more, if there was more excavator stuff, like Bucket repairs and all kinds of excavator repairs 🥳

Awesome, another great production. Good job both on the machining as well as the video production. And yeah, that thing spinning on the lathe was terrifying. Must put a lot of stress on the shaft and bearings on the lathe.

Damn, that comes dangerously close to the ways of the lathe! I love watching your work. When I graduated high school in 1976 I had 2 career paths, either a mechanic, or my first love, working in a machine shop. I let personalities dictate my decision so now I live vicariously through your work! Spot on mate!

Such a wide variety of work coming through the door. It makes for an interesting day. One of the things that set you apart from the other engineers is the short explanation at the start of what and where the part goes. The finish on the flame cut was much neater than I expected. I don't have a favourite part (other than Homey). It's all good. It doesn't seem that long ago when you had 100k subscribers. Now you're knocking on the door of 200k. Well done to all. A brilliant achievement which is testament to the popularity of your video collection. Thank you camera lady. Brilliant as usual.

Great video as always!!! Thought is was interesting when drilling out the holes that on one piece you used the that custom drill to cut out what looks like a slug and on the larger pieces, used a traditional drill to cut the holes. Interesting project that looks great. Cheers mate!!!!

Another great video , as usual , just wondering at the risk of sounding like I’m criticising , was there a reason you didn’t drill them before you cut them or would the torch burn the edges of the hole away ?

Hi Kurtis, another great video, thank you. A couple of questions. (1) Why not drill the holes before splitting the rings? (less measuring, etc, but I assume a space limitation on the machines) and (2) why use the annular cutter for one side, but the 26mm twist drill for the others?

Hey mate thanks for watching, good questions, The voids from the holes would create terrible blow back and splatter from the gas cutting and ruin the plate. The coolant pump is burnt out on the radial arm drill so can't run the annular cutter 😭

Hi Curtis, I was impressed that you got such a clean cut with the torch. When your drills become dull do you sharpen them yourself or send them offsite to another company to sharpen them for you? Cheers Steve

Will the unbalanced piece in the lathe ever run the risk of making the cut uneven. Or is the lathe just beefy enough to hold it...up to a limit of course.

Just curious to know what happens to all the swarf and scrap metal you have at the end of a project. Does any of it get recycled somehow or does it all simply get tossed away? You might mention this in a future video. Thanks!

Homey was like... "Cool, a new chew toy!" When he seen that plaque/sign, lol. Bet he could chew it to pieces too if you let him. Anyway, thought it was neat how the pieces made the twang noises as the gaps opened up from the stress in the metal when you were torching them.

Excluding the late and the mill, what do you reckon a rough total cost would be for all your other tooling? (Plasma cutter on wheels, the facing mill, the plug cutter etc) - I’m betting all those bits to do a professional job cost more than the job is worth!
