Hello HT member,

I’m in the stages of purchasing some machinist measuring and specialty tools that are necessary for me to completely blueprint and assemble a bottom-end on a B18C. I have already reviewed the list that was posted by the brilliant Jeff Evans on his own personal forum. Now knowing the required tools that I need to get I must source these items. I would like to make note that this is my first engine build and I will not be setting this motor up for the track so my intentions are to never open this bottom-end again. Furthermore, I feel as though I don’t need the best measuring instruments on the market because the tools will not get used often. However, I do have certain features that I’m after. I’m willing to pay the extra buck to get the quality.

Below isn’t the full list of tools that are needed, however these are the items that I need to source. I would like for those with experience to recommend a manufacture and retail store for the items.

Measuring Tools:
• dial/digital dial bore gauge
• dial rod stretch gauge
• digital 6” caliper
• digital 2-3” micrometer
• digital 3-4” micrometer
• feeler gauge
• plastic gauge

Other Specialty Tools:
• ring filer
• ring compressor
• micrometer stand

Thank you all

don't forget 1-2" mic , degree wheel, torque wrench

The ones I used were brown & sharpe, mitutoyo, and starrett...these aren't cheap and you wont find them in retail stores. Most precision tools are found in mail order catalogs or online.

i would recommend goodson, most everything that i have seen from is very high quality. Sunnen makes a very nice setting fixture and dial bore gauge. Might be a little pricey but worth the money

What purpose does a 1-2" mircometer do when blueprinting a bottom-end? If I can sacrifice by not gettin this I would prefer; save me 200.00. I'm looking at the mitutoyo digital instruments.

 

to measure the rod journal on the crank(typically around 1.7XX")

Can't I just use a electronic caliper. This has the resolution of .0005". Guess that is alot when taking clearence for a bearing.

Man the list is endless. Like I said this is my first attempt to blueprint and assemble a bottom-end. I have no doubts in myself, its just the required measuring tools are endless. The mics I'm looking at are the electronic mitutoyo and they are close to 250 + a pop. I hate to spend this much when I may never do it again. Where is a close friend when I need one to split the cost and share the product.

 

buy a standard micrometer then, save money there and have all the required tools to do the engine, or any other engine for that matter

Can any mircometer that has a deviation of .0001" be accurate enough? Or should some of the measurements be more accurate in the range of .00005". The determining factor will be the difference of getting a digital v.s dial mircometer. Thanks

 

No engine builders on HT...

they're just too busy building them

Hopefully not rebuilding them...

 

You can't use calipers to measure features that require a minimum resolution of .0001". The digital calipers only have a resolution of .0005".

Calipers also have the shortcoming of having a flexible frame and are too subjective to the force applied by hand and portion of the jaws applied to be very accurate.

More resolution is better, but it won't help you to be any more accurate. A 1% gauge/method error is very acceptable.

 

Well the measuring tools still haven't been purchased. I have been holding off due to the contradiction between buying what I want and what I really need. I had plans to buy a bore gage, so I would do some blue printing during the assembly process. However, honestly what is the purpose when I will be double checking a highly reputable engine service shop such as inline pro. Also I had my eye on the Muitoyo coolant proof digital micrometers. I need at least the 2-4". Just one of these is $225 plus a pop. Is there a way around any of this expense and still assemble the bottom- end myself? Perhaps if it is best to get the mutitoyo bore gage, and then maybe settle on the cheap ENCO economy micrometer set in a range of 0-4".

FYI. I'm working on a turbo build b18c setup. Most likely I will get it sleeved, and will definitely receive rod, pistons, and new bearings.

Advice would be helpful. Thanks.

NO ENGINE BUILD EXPERTISE HERE? ADVICE NEEDED...

 

I was wondering the same thing too

with an inner micrometer, it is pretty hard to tell you are actually measure the "real" diameter or not.. even a slightly tilted, the entire measurement will be off by alot...

but with a high precision digital caliper, one can square out on both end to measure the true diameter of the crank.

Engine builder please shed light I am learning the process to building a motor

Thanks
