Hey everybody, it is Nick here at Higher Precision and today we're going to be doing a video demo on the Fowler bore gage setting master kit part number
Today we're going to be doing a video demo on the Fowler bore gauge setting master kit part number 53-646-010. This bore gauge setting
master kit is the metric version and it will allow you to set bore gauges up to 150mm in diameter with accuracy up to 3 microns or .003mm. So let's
take a look at the kit and what it includes. Within the kit you're going to get a certificate of traceability to NIST for the 33 piece grade AS-2 gauge
block set. The back side of the pamphlet here you are going to get a 1 page manual on how to actually set it up but I'm going run through that today
right now show you how easy it is. Then the rest of the kit you get all the parts to accurately set up your bore gauge so let's dig right into it and
see if we could set this up for you.
So the first thing I'm going to do over here is just grab the base..... the base with two little screws as well and I'm going to grab the support anvil
here too. The first thing we're going to do is take the two holes right here and actually just put the support anvil and secure that to the base. So
the first thing I'm going to do is just tighten these up by hand. I'm gonna come in with a allen wrench and tighten right up here. Now the setup is
literally probably the toughest part about using the bore gauge setting a master kit as once it is assembled, it pretty much stays assembles the most
part. Not many people actually take it apart and put it back into the case each time so most of the time once you actually have the stand set up just
a matter of changing out your gauge block no matter what size you're trying to set your bore gauge
Alright so now the support anvil is tightened to the base here, the next thing I'm going to do is just secure the stand itself to the base and you can
do that with the threaded hole. The same applies just going start it by hand and I'm gonna come in here and tighten it up with the allen wrench. The
stand is secured to the base to the support anvil now we're ready to start setting this up to able to set your bore gage in this setting master. So
the first thing is I did borrow bore gauge from Fowler. This is a 35-160mm bore gauge and I've already preset the anvils
down here to be able to measure a 40mm dimension. So what you're gonna do with the setting master kit and ideally what is ideal here is you want to
stack up the gauge blocks as close as you can to the nominal size you're trying to measure. I made it nice and easy for the demo purpose here we're
doing 40mm so I'm just gonna grab a 30mm block and a 10mm block. I can raise up the quick adjust knob here. I have a bottom flat anvil I'm going put
in there then I'm going to grab the 30mm block insert that into the stand, grab the 10mm block I'm going insert that into the stand and then I'm going
to get the top support anvil and put that in here. I can lower the quick adjustment here tightening the tightening knob. Then I'm going to use the
fine adjust knob to tighten everything down to make sure it's nice and secure.
So we do have to support jaws here and that's what we're going to actually set the bore gauge in between because we know the distance between those jaws
is exactly 40mm. We have the 30mm block plus the 10mm block equals 40mm. Once that's actually set up I'm just going to take this support plate put
that on top and now we're ready to try to figure out how to set the bore gauge in the setting master. So let's take a little bit of a closer look and
I'll show you how to accurately set your bore gauge.
The bore gage setting master kit has already been assembled in preset to be able to set the bore gauge to a 40mm dimension. Similar to how you would set
a bore gauge in a micrometer and or a setting ring, you're going to put the bore gauge in between the two flat anvils and rock it back and forth to
try to find the reversal point. I'll insert the gauge in here to make sure the fixed anvil and the anvil at the backside here that actually does the
measuring, the pin, are both making contact. I'm going to rock the bore gauge back and forth. Sometimes I do find it easy to use your finger and thumb
to just kind of hold the centralizing contacts here just to make sure you make it easier to rock back and forth. What I'm doing is I'm looking for
the reversal point the needle is going go one way, one way, one way, hit zero, and go back the other way. Once it hits zero, that is called the "reversal
point" and that's when we know the bore gauge is correctly set to the 40mm dimension.
That wraps up our video demo today on the metric Fowler bore gauge setting master kit. I hope you did find the video demo helpful if you
