Hello welcome to Enots engineering I'm Alan in today's video we'll be making a tail
stock depth finder out of some scrap material in fact it was a piece of material that I broke a tap off in when.
I was making the grinding wheel Arbor I want to put
some sort of measuring device on here so I can measure the depth of the hole that
I drill when I'm using the tail stock at the moment all I've got are these markings
on the quill which are every two millimeters so what I've noticed is that
on this end of the tail stock the handle has got a machine part and a face.
The only thing holding it is a small grub screw that goes through there
I don't want to do any drilling into the tail stock or or fit anything like a digital
caliper because that means you've got to make something to hold that in place and
then something to put on the end to pull the blade in and out.
So what I thought about was putting a ring round here there's an knurl on it so you can turn it and then
just engraving the markings so basically what we have here is the rough drawing
this is the tail stock end and this is the handle so I'm going to make a ring
that goes over the handle a bit of clearance here 45 degrees for the tail
stock if l engrave this then with the increments for a two millimeter because
from the test we did one turn of the handle it's roughly two millimeters that
will then give me a better guide than the current engravings on the tail stock
15 mm and I want it to fit over this handled 28.7mm
I'll turn the top slide to 45-degree angle so I can put some clearance on the
bore for the tailstock
The part you see here is the end of the tailstock I'm just checking that it will
clear with the 45-degree angle
unscrew the screw from the outside fit this on the end and line it up with the dimpled
And screw the screw back up
put eight the rule still rule to the top of the tail stock and I'm just going to mark
the edge the red felt-tip so when I turn this one revolution and see how many
thou it gives me on a dial indicator on the other end. The dial indicator is just
touching the end of a Jacobs chuck so I can measure one turn of the handle and
give me the reading in thou's
It's 50 60 70 80 0.084" the next thing I need to do as well is make
a small cutout in the top here so I can get the oil can in to oil the top.
In the end it's easier to file a semicircle in you can just put the oil can in
to oil that.
So what I've done now is clock this up true in the chuck
I will take the chuck off with the job in and put that onto my CNC machine
the finished ring with the engravings done and one turn is two millimeters.
This side is just clearance this is for the oil feed pipe with the
oil can so that's just a cut out there so what you need to do now is we're
going to fit this small bit of spring steel into the groove that just sits
In to that groove and then the handle goes into the hole
you can see then that the the face here stops the spring still coming out you
see it springing it also gives you a bit of grip just stop this turning around so
now we can fit this back on to the tailstock see how it works
I drilled a three millimeter hole. Five mill deep so we can fit some brass rivets.
Using the places of guide drill the second the whole for the brass rivet and Counter sink.
Well thanks for watching I hope you've enjoyed it and we'll see you next time.
