What metal drill bit for putting a Piranha on?

[RoyJackson]

Roy the .9 hash mark on the carriage is not visible. It will be almost another 1/10 of and inch of jaw opening before it will be visible. The carriage is slightly past the .8 hash mark. The numbers are to the left of the hash mark they represent. You need to get out your own calipers and have a look at them. When fully closed the carriage will be at the 0 hash mark, and the owner should adjust the dial to read 0 also. Which he has not done. We can only estimate the dimension as show at around .805 as this caliper is out of adjustment as evidenced by the hash marks on the carriage and the dial are not in agreement. I too wish the owner of this caliper would show us this caliper fully closed.

You (and others) are assuming the first hashmark is the "zero"...based upon my experience, I'm assuming the first hashmark is for .100.
Well, reckon we do need the OP to post a picture of that caliper closed.

As I wrote previously, we expect the OP to be able to use his own calipers...

Wonder if he drilled them holes yet?:zzz:

No need. A picture with them closed will only prove if it is zeroed or not (which it doesnt appear to be). You only have to look at the picture to figure out what the lines indicate.

The line to the RIGHT of the 0 mark is aligned with the fixed jaw- indicating 0. The line to the RIGHT of the 1 mark indicates 0.100". The line to the RIGHT of the 2 mark indicates 0.200".... So on and so on. The mark to the RIGHT of the 8 mark indicates 0.800", which is right about where the carriage is. So, if the dial is assumed correct, then it is reading 0.795". If the dial is out of zero, and the hashes are taken on their own, then it is about 0.805" - nowhere near the 0.895" you claimed it was reading.

You are wrong. You will realize you're wrong. And you will feel like an idiot for talking down to the guys who disagreed with you because you felt like you were the one "professional" on the board.

I don't normally get worked up over something this trivial, but I absolutely despise the Princess-Perfect attitude. At my level, in my industry, there are way more experts than "also-ran"s, and plenty of dudes who know more than me and/or stuff that I don't know. I've learned to be really careful about the way I present "facts", cause my colleagues will not hesitate to call you out.

I had a guy interview for an instructor position once and open with the line "yeah, so I know more about guns than most people". Poor guy didn't realize his interview was over before it even really started.

On my pair if I can see the number 8 on the body it is 8???. You do not go back one #.

OK... here is my properly zeroed caliper set to various dimensions

Here is properly zero'ed

Here is .095

Here is .105

Here is .895

And here is 1 inch even

I guess the last thing to be seen is how the Princess handles being PROVEN wrong. By a bunch of non-QC professionals, at that.


Oh...and how the OP's bucket project comes out. That too.

I did request (via a PM) the OP to post a picture of his calipers closed...then we'll have the answer.

I can't tell what his are...the brand name is frequently on the dial face, but all I can read is "Shockproof".
