Stanley tape measures are the best, but you should still always check the scale against a standard to guarantee you don't have an odd bad one. I have only seen one Stanley that was off, but I have seen a lot of the cheap brands be off over the years. At the factory I worked at, we would have to get our tape measures certified to ensure everything was made to the same measurements. The cheap tapes they would buy at least 1 out of every 20 would have to be thrown out. China doesn't care if the measuring tools they make are accurate.

Wow! This is an excellent tutorial on lineboring, building out with weld material, and all the rationale for why you did it the way you did. And did it properly without taking shortcuts that would have failed, likely within a few months! I love it when things are done correctly, and not just “good-n-nuff” for now! Thank you for the painstaking effort you went thru to film all this. Thanks for sharing your machinist and welding skills with us also! As an aspiring welder, who plans a side hustle when I retire, your videos sure are a great reference for me. Thank you Greg!

You're talking about the guy that said well you can just weld that by hand. When i first daw the channel about a year ago i was blown away. I can't believe this is a real thing i would have figured some company just makes an oversized bushing, you machine it the hole, pop it in and thats that. Idk ehy but the fact that this machine slso welds to me is just crazy lol 🤣 thats awesome 😎

I used to do this years ago. We used a tiger torch to heat the bore and chilled the bushing with liquid nitrogen. The bushings just dropped in like nothing. Sometimes we used a horizontal mill...made things a lot easier for that chamfer by using a boring head. We also used a micrometer feed for the cutting tool that could index the cutter to depth at .0005" increments for very accurate cuts. For measuring the bore with the line bore bar still inside the bore, we used an attachment for a bore guage that spanned the bar...very accurate as sometimes the math on a cut would be good but the cut could go wonky after the bore has been cut...oops!!! Kinda' like a rocket launch...fingers crossed without the micrometer adjustable tool bit holder.

If you can outfeed your facing tool to the same feed rate as the thru travel feed rate, think you could get a 45 chamfer like a Wohlhaupter auto facing head. May have to snug the bar collet and facing head gib to reduce chatter. Climax might have other suggestions. Nice video OFW!

@@viktorsmekaniska2733 Dude I was joking of course Kurtis has all the sht he needs, and more!🤣
Another fine job done in America, send a copy around the world!!!
If you can outfeed your facing tool to the same feed rate as the thru travel feed rate, think you could get a 45 chamfer like a Wohlhaupter auto facing head. May have to snug the bar collet and facing head gib to reduce chatter. Climax might have other suggestions. Nice video OFW!
That was a extensive job several hours but as always job well done in the end ! And as always very professional ! Thanks for explaining how you get center when line boring worn holes ! I also liked the inserts you put in for the bushing to butt up against to keep them from sliding towards center ! I can tell you take pride in your craftsmanship ! 👍👍
Several hours? Dude try probably 20+ hours for this. I don't even want to know what he charges for this. Cat charged me 3k to line bore a new attachment hole on a quick disconnect that was brand new on a small e85 bobcat lol
Crackin video! Great explainations
very good and very nice work !!!!
Well young man that was a very interesting watch great information on actually how you do the line bore welding and how you measure it all out. Also as you say 48 minutes in 15 seconds . That makes that a long job .. not a 5 minute as it seems on video . Many thanks
Shout out from the 209 👍💪
You accomplish more in the first thirty minutes of your day than most today's guys can accomplish in eight hours.
Did many of those over 25 years in field weld & machining.
Excellent work!! One could pinch the hand very bad or loose a finger!!!
I spent over fifteen years making Bushing and bearings for Cat among others. I done all these on Programmable Mazak Lathe Machines and Horizontal Milling Machines to drill and tap the grease inserts. Many may not know it but they all require Bronze Inserts with oil galleys cut into them which are the Bearings for those massive Bushings.
