This question is two-part.

First off, has anyone used or heard of "SPI?" Are they fairly quality? I am looking to pick up a set of 0-4" digital micrometers and my local machine supply company carries a brand called SPI that is very resonable priced and seemed to be of excellent quality.

I can't find any links to their stuff really, so I think I will scan in a pic out of their catalog later this evening.

Second question....

What are the essentials for building honda engines?

0-4" outside mic

telescoping bore gage set? or do I need a hole mic?

If someone could list out the essentials that would be great.

 

anyone that can answer the second part of the question?

 

spi is decent .....there beter then the Fowler brand and way better then the harbor frieght stuff. I have an spi 3-4 mic and i like it but mitutoyo is usually a better deal (there both Japanese made, i think)

 

are those for measuring the bearing size? if so, how much for one?

 

personally dont like digitals that much. to easy for calibration to get messed up, also just make sure yours comes with a piece of round metal to make sure he calib. is right
