I could but I think the market is limited:) I often get asked how to tackle a particular job. The frustrating thing is what look years to sort out can be passed on in 10 seconds.
My on site line boring is about done. I have a couple of lathes,a mill and a couple of line boring machines in my workshop. If they can bring it to me I will machine it.;)

If you have a skill worth knowing you can either write a book, pass it on to apprentice or take it to your grave. I don't mean to sound too pompous about it, but everyone owes it to their teachers and to mankind in general to pass on their knowledge somehow. There have been plenty of books written on far more esoteric subjects than line boring, and what better legacy to leave behind than a published work?

By the way Ray, this is absolutely not a personal rant at you, just a general observation.

Quick, everyone write down what you know before it's forgotten!

Thank you,now you see it in print.There is nothing more satisfying really than helping somebody over the hurdles of learning something that you know and have worked hard to learn without asking anything in return because our payment is in seeing someone use what you helped them with successfully.Ron G

I enjoy passing on what I know. I answer quite a few PMs from people here and have also trained up blokes who are starting out. As far as writing it down it would likely be difficult. You could address specific jobs maybe but that rapidly gets out of date.
How do you line bore? It really is a simple common sense job. You have a stable mounting system. Make sure your bearings are lined up. You make sure your bars are level and parallel to each other. Its not rocket science. And just like anything else if you have been doing the same thing for 28 years you would have to be a complete dill not to be good at it.
I would enjoy more writing about some of the characters I've worked with in so many workshops. Thats what I've enjoyed the most.

Mentorship is a relationship in which a more experienced or more knowledgeable person helps to guide a less experienced or less knowledgeable person. The mentor may be older or younger, but have a certain area of expertise. It is a learning and development partnership between someone with vast experience and someone who wants to learn.[1] Mentorship experience and relationship structure affect the "amount of psychosocial support, career guidance, role modeling, and communication that occurs in the mentoring relationships in which the protégés and mentors engaged."[2]

I'd be interested to know if anyone here has written a book and can give any insight into the subject, motivation, publishing etc.

Is KOO still active here? He's had something published I believe.

For anyone wanting to know more a thread could be started. There are a number of line borers here using a variety of machinery. Im sure most if not all would be happy to share experiance and knowledge.

Off topic warning, a little.

Well don't think it would make a book but often thought I should have kept notes about each job especially the odd ball ones.

Like the time when I had just started working on this equipment as a young guy and was sent to the next state to check on a report of a 12V-71 Detroit genset not starting. When I got there they told me they had tried a couple times and it finally did crank over and start, but was blowing a little white smoke out of on bank. Called back to the shop and talked it over with my boss. He said if it starts and sounds okay hang around and watch it for a couple hours and let him know how it seems. So I tell the boss at the plant what i was told to do and he said sounds good. Cranked up the pair of 12V-71's that were in the same trailer and they started up the crushing plant. Meanwhile I parked my truck a few feet in front of the trailer to sit back and listen to the music of 24 cylinders of Detroits screaming away. About fifteen minutes later I noticed a big change in the sound and the plant foreman came over and asked why I shut down the one genset. Told him I had not been out of the truck. So we went in to check on the genset and that's when we found the the problem was a bit more serious than a little white smoke. A large hole in the side of the block with some parts on the outside that should be on the inside! Called back to the shop again and told the boss, he said well help them unhook it and pull it out of the trailer and we will have a truck there the next day. To make the story a little shorter, the problem was that it had rained hard all weekend and the exhaust system left something to be desired. Water down the stack and hydrostatic lock of the engine whe they bumped it enough to get it to finally start it bent the rod on on cylinder. This caused low compression that gave the white smoke. New block and a couple rods and such and got to rebuild my first 12V-71.

I made reference to this once before in my comments on this board and not being too proud of it I don't blab it around much and better yet I hoped noone reads it much either but when I worked for the concrete producer as a driver (my job description changed over the years) we were slow one day so I backed the loader (a Trojan 4000)up close enough to the wash rack so that I could hose it down and look busy while waiting for my turn to deliver a load some where partly and partly to hear that 853 Detroit make its beautiful music while turning 2800 RPM as it got everybodies attention to stay out of the way.
Well,to those that have seen them,the two exhaust pipes from the engine curl out through the engine nacelle into one muffler mounted on the side of it and exit from the muffler in a balogna cut single pipe that could hold a lot of water until it seeps back into the engine exhaust manifold and whichever cylinders happened to have some valves opened waiting for some innocent operator to attempt to fire it up and the hydrostatic lock that resulted was followed by a ride to the dealer for a rebuild.I never heard anything about it because noone there had a suspicion what caused it and I was not about to say anything but I wondered while I was doing it if I might regret it.Well.......I still do.There....I said it again.Ron G

it was easy for me to get a book published because i had written the story and mailed them out for people to enjoy. i live at the end of the world and all it took was the publisher sending me a disc that contained the pages for a the book. i put the words on the pages and adjusted a few things then sent them the disc. then they printed a rough copy book for proof reading and once everyone agreed then a run of 200 books was printed. now 10 years later i just phone them with a credit card and both my books are printed and shipped to me in 4 weeks time. it is very easy and i never thought i would be a published author but th ecomputer makes me look smart, lol.

Yair . . . .

If anyone is interested I can give an insight into conventional publishing on a TGIF thread.

I'm no expert but have had books, articles and essays published for money. These days it's a miserable cut throat business and "who you know" can be more important than how well you write.

Producing a book ready for publication is a laborious process and I have worn out many printers on hundreds of drafts.

King of Obsoletes experience as described is "different" in as much as anyone can get anything published if they are prepared to pay the publisher and sell the books from a website, markets or even door to door.

For many folks this is a very viable option and King of Obsoletes books are a classic case in point . . . they are an interesting read but may have been difficult to sell for upfront money and royalties . . . the niche market syndrome.

Cheers.

Question for RayF,
Hitachi bushing interference-fits 0.0035” per in diameter, how are the OEM bushings installed @ time of manufacture?

I'm sure that Ray will confirm htis but AFAIK liquid nitrogen is the only thing that will work to give you enough shrink on Hitachi bushings to get them in the bore without damaging them in the process. It certainly was the case on our 3600 machines anyway and even then we always had a big cylinder stnading by to press the bush in the last bit if it got tight before it was fully home.

Stan, I'm not 100% sure. I have been through a boom,stick and bucket plant in Jakarta but didn't see them fitting bearings. I have never seen any marks in Hitachi bores that would result from pressing.. The only thing left is heating the bore and liquid nitrogen.
Hitachi bearings with 35 to 40 thou crush in my experiance are 250 mm and up. A good even heat to 250C and the bearing in nitrogen till its stopped boiling and they will fall in. I find the harder ones to fit are the small Hitachis. A 115mm bearing and 9 thou crush is a challenge.
