i did not chew you out but there are steps to going at this.hopefully there is someone thats done it more then you to help or you jump in with both feet the easy part is boring the hole .i can set up my boring bar and bore all day and would be happy like i still had a good mind. but thats 1/2 the job .the way i allways learned was by doing and learning with the machine you have Tq plates are needed for some engines more then others not every engine needs them but some blocks move alot more then other blocks so if you want nice round holes you buy TQ plates or make them. i have them for chevys and sbf and harley davidsons they are very pricy costing $500.+ now it takes time to pay them off if your getting $200. a bore and hone on a V8 there wear and expendables honing oil . honing stones . wear in time .cutter bits .diamond dressing wheel. then hold all bores under .0005 you will find this is not a job for the weak as for tooling and machines alot of my stuff is not new but old some of it s way older then me but i can make it work and i have used it enough to know how hard i can push be for it starts pushing back. i do this stuff evey day this week i hot tanked 4 454 blocks. deck a SHP block with BHJ tru-deck -plate set up the Rottler with my jug plate to bore out HD jugs that have a 4.155 bore /hone them but first i had to bore all my set up stuff out for the bigger bore stuff so i like to mix it up some what day to day

Pat, as far as boring the block to size or maybe .001 or so under where you want it and just giving it a quick hone to give the cylinder the right finish......is that something that a lot of people used to do or did my old friend just pick up on a bad habit somewhere back in the 40's? I was just wondering if he just stuck with the old way of doing it and never caught up with the times, or if he just did it wrong the whole time.

there many ways of doing the job .002 is the least i take out more like 003 this way i know the all folded metal from when the cutter removes the iron is gone .so i have a nice finsh on the bore this is at a micro level . i still use the AN sunnen stuff on my hone so after boring it,s a AN 101 then 200. then 300. then i go with plateau finsh brush 5 times down the bore . this is how i do all bores

Before the 1970s there were no set standards for determining the competence of automotive mechanics. The non-profit National Institute for Automotive Service Excellence was established to remedy this situation and provide a way for consumers to evaluate a mechanic's ability.

How ever, many people display that sign for all types of repair, and they are not certified in all the fields that they clam. A little misleading to the unexpected person. Taking a test is not the same as being a competent mechanic. You have to earn the right to display that, not just passing the tests. I know many people that are good on paper, but that's it.

Applicants for ASE certification must pass a written test and demonstrate at least two years of experience in their chosen automotive field. Upon successful completion, applicants are certified. Certification is not permanent and must be reaffirmed through retesting every five years.

I know you were teasing. I ain't mad at you, but I have to defend myself don't I? When I covered fundamentals with my students I covered ASE and pretty much told my students the same stuff you said there. It kind of goes two ways. I will admit, I don't rebuild automatic transmissions for my customers but I have the ASE cert. in that area. I was able to pass the test because of the book knowledge and limited experience working on my own transmissions. I send all my customers to a local transmission shop. I don't mislead them but they feel that I have enough knowledge to properly diagnose the problem and make a good recommendation whether or not the transmission needs a minor repair that I can do or if they need to take it to a shop for a complete overhaul. With that said, a lot of people do have the certifications and aren't that competent when it comes to hands on. On the other hand I had a guy working with me here that was as sharp as anyone I'd ever seen. He was very good and fixed pretty much everything he touched and was fast, but he failed every ASE exam he ever took LOL. After taking the exams I would say you would have a hard time passing them with no experience at all, so you have to know a bit about the subject for sure, but I'm like you and still don't think you can put as much stock in them as most people do. ASE doesn't make you good for sure.

thanks for the link. I saw some interesting topics there I'm going to go back and read.
