this is a drill Center finder you can pick these up on ebay they're only about
six pounds to buy these are very useful if you ever need to drill down the dead
center of a shaft or any round piece of material. There are several ways to Mark and
drill the center in that direction if you want to drill the center that way
the best way of doing that is by using a bell punch which I have covered in an
another video for the sake of spending 6 pound on one of these it is well worth
it because these can save you a lot of time and they are fairly accurate so if
you ever need to drill down the center of anything that is round such as round
bar or a piece of tube or a piece of round wood you can quite easily do it by
using one of these obviously you're going to need a pillar drill to do this
and you do need to ensure that if the base is movable that it is square to the
actual drill bit this will work on various diameters and I've got some bar that
is approximately 20 millimeters there you can see that it will work on that
absolutely no problem at all and it will also work on larger diameter pipe etc so
to use this we need to fix it into the chuck of the pillar drill you can then
take your vise place that on there this example I'm going to drill through this
aluminium tube so I'm just going to clamp that in there ensuring that it is
square so that tube is now firmly clamped in the vise now just need to move that
down to the workpiece and you can see that in the centre there there is a line
and the line on the shaft we need to touch both sides of the center finder
and ensure that the line in the center is aligned with the center above so if I
press that down on there
you can see that that is actually perfectly aligned if that was to the side
slightly like so you can see that the two lines are not aligned which is
incorrect we need to get those perfectly aligned once we got it to that position
we then know that we are in the exact center of that tube so I'm just going to
tighten up the Vice in that position to stop it from moving then we're just
going to check that again to ensure that the vise has not moved and that is still
in the correct position we can now undo the chuck now I'm just going to insert a
center drill and that will just ensure that we get the drill started correctly
so I can now put some safety glasses on we can now start the drill
and then we can proceed to drill the hole
you can now remove the center drill we can then install the drill bit and then
we can proceed to drill the hole and I just like to say thank you to a few
people who have been translating the titles and descriptions for some of my
videos, that is really helpful so thanks a lot to those people who have been doing
that
Then remove that from the vice you can see that we are all going all the way
through the center of that so for the sake of spending 6 pound that is a very
useful device if you need to drill the center of any round materials such as a
shaft for a machine or anything like that, So I just thought I would take a
bit of time out just to show you that it is a very useful piece of kit for the
money I'd like to thank you to watching this video please subscribe if you
haven't done so already
