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 😎

Very impressed, I agree with bore welding, Welding by hand is just NO, not even attempt it. I've been welding for 44 years Paid for it for 39 years. Not only keeping it consistent, I'd like to see someone do it by hand too. Love your line boring tooling, looks like might have cost a few bucks. I have an idea for you chamfer but find it difficult to explain with keyboard. I would make 1 tool holder adapter and feed a 45° carbide straight in slowly, but because how slow it needs to be fed it might not save time (20 mins). Those little imperfections will be totally fine. I didn't realize how many hours were involved. It came out real nice, Well done.

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!

Hey bud, great video, I’ve been line boring here in Arizona for the past 4 years for my self…..I actually have the same set up you do as far as your climax electric motor. Climax is the best by far for mobile line boring jobs bar none. I was going to tell you, not sure if you know, but on caterpillar excavators they don’t run a shoulder in their B-pin bores from the factory, they actually put twice as much crush on the bushing. I use to work for empire-cat here so I’ve seen all the specs on these machines. I’d rather it have a shoulder and put the rule of thumb .001 of crush per 1” of bore instead cuz pressing double the crush sucks ass. Great video bud, hopefully I’ll start putting some out as well but I have a contract at a mine that takes all my time…and they wouldn’t like me taking time to video it.

@cb7903 Жыл бұрын

I'm a machinist and have done field machining with climax line boring gear on mining equipment for closer to 10 years now. When i do the bevels on stick bores, i use that same 12" facing head. Simply use a cutting tool with a 45° geometry. This way you're using both set screws to secure the tool. Then adjust the facing head to where the tool is the right height of the bevel and then lock the gib set screws (3mm Allen key i think) so that the tool post that rides on the dovetail does not move. So i remove that clicker or have the facing head in neutral direction cause I'm not facing, only plunging it by hand. Itll take a few cuts up and down the bevel but it should blend in nicely. It's a simple and easy way to go out and it shouldn't chatter. That bevel is just for a rubber seal that goes over the stick bevel and quick attach bevel to reduce dirt going in. The rubber seal has a clamp on it so if you're a little bit too big or small, the mechanic can adjust the tightness of the seal.

@cb7903 Жыл бұрын

One thing i want to add about setting up. I do the same thing as you, cone those upper stick bores and measure keyway to keyway with a measuring tape. However, that's only checking one dimension, basically your center to center (the horizontal). But how level are the bores to each other is what I'm getting at?. What I would do is set an 8" machinist level to the upper stick bore bar, and then transfer that level to the stick bores you're machining to see whether that bar could be pointing up or down vertically. Btw I have an excel spreadsheet of bores sizes for that type of yellow equipment if you need it 😊

@theessexhunter1305 Жыл бұрын

Hi, Had a think about your question on how to create a even chamfer. The problem is to much tool face which causes chatter. I think you need to make a holder set at the angle you need to drill a piece of bar round or square with a hole down the centre the tool shank size. Mill a flat on the tool shank and then on the holder drill and tap a series of holes. Use machine set screws to keep the tool in the right orientation and you can advance the tool out on the angle so you take a cut back off advance the tool and go back in that way it will be small steps just like on the lathe feeding in by hand. Regards Tried you email address but the US side is rejecting it so sent it here.

@Ian-iu2tl 10 ай бұрын

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.

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.
