Engine Building/Machining sub-forum

OneBadTurboCRV

In my opinion a thread would be pointless. It would fall through the cracks just like all the useful threads in the FAQs. It needs to be a sub-section or forget the whole thing in my opinion. People need a place to look through the forum list to post their questions about specici questions that directly relate to the topic.

Let's face it, not everyone "hangs out" in every single section. I know I sure don't. I have ones I frequently visit and others I seldom click on unless I am bored. The rest, I have absolutely zero interest in, but guess what, there are obviously people that do enjoy going there. Plus, if I ever needed to ask a question about Lighting (LOL) or Wheels or Paint or the list goes on, there is a dedicated section for that. It would only make sense to have a DEDICATED sub-forum for Engine Building / Machining.

Would I frequent the EB / M section and try and contribute? Yes, without a doubt. Would I ask questions? Most likely not, but you never know. I already made a decent case on the first page why we should have one and I see no counters. Sometimes people don't know they want something until it is right in front of them...

It can only HELP the website traffic, not hurt it. If I were in Honda-Tech's shoes, I would be trying everything I could to grow the website rather than let it fall through the cracks of time. Afterall, this IS a vehicle base website right?

okay just so everyone is up to date on this situation. The possibility of this being created is highly possible. It will require some assistance from members to be strong participants in that sub-forum. I don't have a set date of when it might possibly come out, but its in the works.

Continue to bring members into the voting of it and show support.

This x2.

More tech, less generic answered questions.


specs, methods, p2w for hp numbers, bearing clearances etc. This is a great idea.

Rugger53

As an old motorhead I am always interested in the wherefores and whereases.
I'm all for this coming about.

PyroProblem

Well everyone, I've been assigned a small "Homework" task to help get this thing going.
I will hopefully have it done by this weekend.

One step closer! !

Thanks to everyone that is helping this come to life!!!

Too many subforums in this subforum of subforums. Pages are moving slowly

whitesihatch

finally some good tech, cant wait.

GoldieWang

Although I know nothing about machining I would love to be able to read on it and learn. You have my vote!

blackeg

all forums, this and all others im on car related or not seem to be moving slower and slower. i think its all facebook now....

Here is a part of a post from Earl (RIP) so as not to create a useless bump. Maybe it will help some people out there.

Here is a chart of Honda B series bearing thickness by color. To calculate actual bearing clearance, use the following formula:

BC = IDBT – ODC – (2 x BT)

BC = bearing clearance
IDBT = inside diameter of bearing tunnel (housing bore)
ODC = outside diameter of crank journal
BT = bearing thickness

Main Bearing thickness by color
Blue 2.013-2.010 mm 0.0793”- 0.0791”
Black 2.010-2.007 mm 0.0791”- 0.0790”
Brown 2.007-2.004 mm 0.0790”- 0.0789”
Green 2.004-2.001 mm 0.0789”- 0.0788”
Yellow 2.001-1.998 mm 0.0788”- 0.0787”
Pink 1.998-1.995 mm 0.0787”- 0.0785”
Red 1.995-1.992 mm 0.0785”- 0.0783”

Rod bearing thickness by color
Blue 1.510-1.507 mm 0.0594”- 0.0593”
Black 1.507-1.504 mm 0.0593”- 0.0592”
Brown 1.504-1.501 mm 0.0592”- 0.0591”
Green 1.501-1.498 mm 0.0591”- 0.0590”
Yellow 1.498-1.495 mm 0.0590”- 0.0589”
Pink 1.495-1.492 mm 0.0589”- 0.0587”
Red 1.492-1.489 mm 0.0587”- 0.0586”

Although most people do not have inside micrometers, bearing micrometers or snap gauges, you can still use this chart when using plastigage to check bearing clearance. If you want to increase or decrease a bearing clearance, you can calculate how much of a color change is necessary by looking at the changes on the chart. Remember you can mix colors for even a more fine-tuning but it would not be wise to jump more than one color. In other words, do not mix a brown and yellow bearing together to equal a green clearance value. Just use the greens together. It is ok to mix a green with a yellow or a green with a brown. When doing your rebuild and replacing bearings with like colors, you still must check your results with plastigage to be sure. Don’t assume anything. Also remember, when swapping to aftermarket rods, throw the color codes away as they will not work anymore. You need to start from scratch to obtain your desired clearance. On the other hand, you really cannot measure accurately to the nearest .0001” without machinist quality tools, so don’t get carried away on that last one ten thousandth of an inch variance.

Same here. Would be great to have other machinists on HT review other machinists' work and practices. For the most part, you just have to accept whatever your machine shop says and hope they're right.

ryanplayjoint

Sounds like a great idea, the amount of time this site has been around I'm surprised that we have not established a dedicated engine machining forum.

PyroProblem

Agreed 100%. Thanks for your vote.
Keep your fingers crossed! It hasn't been completely shot down yet so there's still a chance we may get this.

Keep the votes coming guys! The more positive feedback we get, the better chance we have.

PirateMcFred

You don't need a forum to learn how to do things. Learn by doing it and post up if you want to share.

Put the phone down, stop FaceTubing go figure it out yourself. OBD-0 cars are as old as the internet. Whatever you're trying to do, it's been done before, look it up.

PyroProblem

Pirate. Been reading and learning from your posts for years and I respect your opinion, and I agree with what you said for the most part.

My intentions of this topic were to shed some light on the automotive machining industry and it's common practices. Very few of us have access to machining equipment so unless you know somebody or are in machinist school, it would be difficult to do these things firsthand.

Engine assembly/ building on the other hand can be accomplished by most with basic tools and a few precision measuring tools and SHOULD be and CAN be learned through practice. I'm a strong advocate for doing things yourself and learning through trial and error. I just don't believe machining is one of those things.

I'm not a fan of Facebook either. Haven't had a FB account in 5 years. People get so wrapped up in social media, virtual friends, and updating statuses they forget about the real world stuff. Like real friends actually hanging out in the garage and actually turning wrenches.

Death_to_Thieves

This is a great idea.

PyroProblem

Thanks for your votes everyone.
Keep them coming!
I frequently see threads that pertain to this topic but unfortunately they're mixed in with other non related topics and all over various sections of HT.

I saw a thread the other day on how to " correctly and thoroughly clean a crankshaft" which involves removing the ***** in the crank and cleaning the passage and replacing the ***** with plugs. Good information!

PyroProblem

Bumping this for more votes and support.

Don't you guys wanna at least TRY ???

Or are you all satisfied with these subjects being thrown in with the rest of the "why won't my swap start" , "my vtech doesn't kick yo" and every other same old mundane topics that have diluted HT over the years...

There are 2 people ready (Actual engine machinists) and willing to be apart of this and contribute and share their knowledge.

2 People that Sleeve, bore, hone, deck, O-ring, resurface, and mill HONDA ENGINES ON A DAILY BASIS.

This_thread_sucks_now

Make it read only to people below 1000 posts and I'd vote "yes" to your forum. If that's unfair then allow "write" privileges on a per user basis on appeal to a forum mod.

Ban people from H-T outright that make "help, my ****'s broken" threads in your new forum. Zero tolerance.

If either or both cannot be done then "No" to your forum.

Dorkenheimer

This seems like a no brainer to me. OF COURSE we should have an engine machining section! The more I think about it, the more sense it makes. We could/should have sticky's at the top for torque specs (omg please) alone for every bolt and nut on every platform! Machinists can discuss their theories, practices, tools they use, experiences, etc. Could be a place to have in depth discussions on head work, flow, cfm, or hell, even engine theory.

It does seem much more sensible to pile up all the VERY useful info into a sub section. Collectively, we have A LOT of info to post.

jimbo slice

I'm in on this idea. Still a lot to be learned from this site.

jdmconcepts

I'm in for this and willing to contribute to a machining sub forum with tech, pictures, videos and even theories.
