i like the cylinder bore worksheet so i found one online for myself, thank you. every video i seen on doing this people use a dial bore gauge, would you recommend against a digital gauge?
I really love this spread sheet did you make this in excel? Trying my best to make one it is amazing!!! I am in school for associates in automotive systems and technologies and I'm a female so I'm gonna get a lot of crap for it but it would be super helpful. The video itself was full of great information so thank you!!!
The spreadsheet is Excel. Excel is very useful for keeping track of data and measurements like this, and can help prevent arithmetic errors in the heat of the moment. Measure twice, cut once! Get the numbers correct before making decisions, and use whatever tools you can to help get it right. Being a woman in a skilled trade does not give your fellow students a free pass to harass you. You should not expect to take crap because of your gender, and if anyone offers crap because of it, they need to be shut down immediately. There is no place for this - anywhere. Where skilled trades can be harsher, and deservedly so, is on competence. You are hired to do a job, you had best know your shit and do your job to a high standard. If you are a terrible tech, people will let you know, and an environment with deliverables that can be absolutely assessed as “good” or “bad”, “pass” or “fail” can be a new and intimidating experience for those not used to it. It can be very tough to hear the word “fail” if you have never failed before. And you will do your share of failing. Not because you are female, but because you are *new*. The skills you are after require study and practice; you don’t get them by walking in the door. So apply yourself to your studies, work hard, become the best tech you can, and if you strive for excellence, you will do fine. Take performance-related feedback to heart, fix the problem, and learn from it. And if any Neanderthal does give you crap because of your gender, makes inappropriate comments, or takes inappropriate actions, report that shit immediately. We don’t need people like that in the trades, and you don’t deserve to be on the receiving end of that behaviour, no matter how good (or poor) of a tech you are. I’m glad you liked the video. Good luck in your studies!
When measuring bearing oil clearance you measure 90° perpendicular to the parting line not where he was measuring. The reason for this is because the bearing shells are not round they are thicker in the center(crown) then at the edge. So that reading is wrong it wont have that amount of oil clearance
That spreadsheet is great! Plus. when set up properly, it will calculate the bore sizes(top, middle, and bottom). It just eliminates a possible math mistake and or transposing a number. The spreadsheet is a great idea. Also have to mention the straw. Thank you so much for your time and effort you put into this video. Much appreciated!
You Zero'd the bore guage to a measurement using a micrometer, then you measure the bore. -As stated at 10:13: The distance shown on the bore gauge is "the difference in size between the bore set at the micrometer and your recorded measurement." - At 10:48, you state: The measurement read on the bore gauge is .006" LARGER than the bore set at the micrometer. Isn't that measurement actually .006" SMALLER than the bore set at the micrometer??? IE - If you set the bore gauge to 4.000" and see a reading of .003", your bore measurement is actually 3.997"?? Not trying to be hyper-critical of your video, I am just a very novice hobby mechanic trying to learn the trade and your video has been very helpful! I just want clarification, if anyone would like to confirm or correct my comment, it would be much appreciated. Thanks!
1. I'm lost as to where the minimum value would be if you are jumping steps I would of like to know where the direction is going for the needle if you're trying to set the minimum in 9:26 so is it Clockwise or counterclockwise because then it gets a bit more confusing for me, sorry man. I'm not the brightest but i'm also lost as to why it's not read from the 0 Clockwise to figure out measure rather it was Counter clockwise. 2. I haven't gone to school for reading bore gauges or machine work but i've gone to tech school for auto. Also, why is the gauge zeroed out from the 3 in 10:24? I understood everything else but the others not 100% a clue. Hope i can get a good understanding and hoping you can answer my questions. :D Pretty please! 3. Has anyone told you that you sound like aVe? haha Maybe in the future if its possible if you could redo this and make the dial bore gauge indicator visible to the camera? 4. Would you offer the excel spread sheet and also make the x and y measurements on the excel blue circle/bores where they're located too... Well whenever you're ready and done with how making it good. :D I remember going to school and being told by an instructor and a student about thrust and anti thrust sides of a piston.
1. So a DBG is a relative measuring device, not an absolute one (like a ruler). You first set it to a known zero point (using a micrometer) and then the distance either side of zero on the gauge is the difference from the set distance. At the 9:26 point I'm checking to make sure that the minimum distance measured in the mic is at zero. The mic is set to the shop manual's bore diameter. Once in the bore, if the needle reads on the clockwise side of zero, then the bore is smaller than the set distance; if it reads counterclockwise, it is larger; 2. That just happens to be where the needle sits at full extension (when it is not in the bore). It doesn't mean anything. What matters is the reading in the bore; 3. AvE sounds like me; 4. The spreadsheet is pretty simple - it's just measurements at different parts of the bore, and the delta from what the shop manual says is OK.
So for all the replies back. 1. I understand now with the gauge because i kept trying to think if i did this would i add or subtract the measurements i got myself confused when i should of just taken it a simpler approach. 2. What you're saying is it doesn't matter whether you zero out the gauge because no matter where you read it backwards it says 6 thousandths of an inch right? Thank you back for the reply. :D
I’ve build championship winning engines for many years , he’s doing this half assed. And was way off on checking the oil clearance. Also his method of measuring / setting the tool left a lot of room for error. I’m not trying to bash this guy just pointing out I only 10% agree with his technique.
I like your idea using the straw on the micrometer.
Seriously, a great idea! It was my golden nugget from this video. Thanks for the video.
best video for using a dial bore gage
Thanks!
Thee best video for using micrometer thanks man.
Did you ever complete your spreadsheet? Thanks

jesse hamilton , I caught that too. That’s all I needed to see to know I wouldn’t even let this guy rebuild be lawn mower.
liked that spread sheet where did u get it ?
I made it myself. Once I get it to the point where I'm really happy with it, I'll put it online.

I noticed in your spreadsheet, you are subtracting the measurements to the nominal bore value. That answers my question, thanks.
1. I'm lost as to where the minimum value would be if you are jumping steps I would of like to know where the direction is going for the needle if you're trying to set the minimum in 9:26 so is it Clockwise or counterclockwise because then it gets a bit more confusing for me, sorry man.

I'm sure I'm not the only one waiting for the other 90%...
