Looking to buy a few new measurement tools and I would like to get a dial bore gauge, but the graduation on the Fowler Dial Bore gauges is .005. I dont see the sense of using the dial bore gauge with that graduation when my Fowler mics go down to .0001. Saying that should I just invest in a nice set of telescoping gauges instead of the dial bore?

 

Come on now

 

there is dial bore gauges out there that go down to .0001, ive used them 2 different places i worked. dont rememeber the brand tho. check MSC direct

 

I don't see a mechanical bore gauge listed with that resolution. This one cost a left nut and half a sack though

The grad is .0005 not .005.look again at the ad.

 

Read now

 

I prefer my Dial bore gauge. However I own telescoping also. It takes a little time to get the "feel" of a telescoping gauge. I still second guess myself with those things. Dial's are best for me

 

I dont use dial bore gauges but probaly brands to look at are Brown & Sharpe, Mitutoyo, and SPI. Fowler is a pretty decent brand. Really comes down to how much you want to spend.

 

SPI is junk.

 

There drop indicator isnt to bad...haha. Not sure if there good dial bore gauges are any good. I personally use mititutoyo/starret stuff

 

I'm probably going to go with fowler just because I dont use them enough to justify spending huge money. I did read the ad wrong and it does go to .0005", is that ok when im trying to read down to .0001"?

My machinist already measured and bored my block so all I need to do now is measure the for all of the bearings. That being said I should only need a 2"-3" mic and a 2"-6" dial bore"? The dial bore gauge through fowler is only $20 more than the telescoping gauges.

 

If you have a calibrated 3"-4" micrometer and a generic bore gage then you can zero the bore gage to the micrometer. As long as the bore gage gives repeatable numbers you can get your .0001 resolution from the micrometer through comparitive analysis.

The bore gage can be pretty cheap. Just make sure it reads consistantly and invest in a nice 3-4" mic.

I wouldn't use telescoping gages to gage bores.

 

I'd rather not but the telescoping gauges, and this is a prime opportunity to buy some nice measurement tools. Fowler is having a tool-a-thon sale and I can get the mic $35, and the 2"-6" dial bore gauge for $86. I d rather get the fowler stuff rather than some ebay special for $50. My cylinders have already been measured and honed, so will I only need a 2"-3" micrometer and the 2"-6" dial bore gauge to measure for my bearings?

 

If it is a Bseries, the Rod journals on the crank are 1.771

 

Cool, thanks don. So i will need the 1.4"-6 inch dial bore and the 2-3" micrometer

 

I'm about to order some measurement tools and just want to make sure that my list is correct. I dont need to measure bore because the machining is already all done and the pistons are all fitted. So I just need to measure the crank journals, bog rod ends, and the mains on the block. For this I have a 2-3" micrometer and a 1.4"-6" dial bore gauge on my list. Is that all I will need or will I also need a 1"-2" micrometer?

Thanks for all the help guys!!

 

would you please post links to the gauges you are looking at?

 

http://www.gaging.com/toolathon.htm is the link, and you have to download the pdf of the tool-a-thon catalog. Im looking at the economy 1-2" and 2-3" mics and the 1.4-6" dial bore gauge. My machinist uses starret and mito pieces but recommended fowler for the price and for the amount that I will actually use them. Let me know if you need part numbers

 

Yes, you need 1-2 and 2-3 mikes.

 

T52-646-100 ?

 

I just ordered the:

T52-646-400 - 1.4" to 6" dial bore gauge
T52-229-202 - 1-2" Economy Micrometer
T52-229-203 - 2-3" Economy Micrometer

I think those should be almost everything I need to do my measurements. I have feeler gauges already.
