Hello welcome to Enots engineering I'm Alan in this video we test this magnetic
standing from bang-good it looks very pretty but will it do the job
we'll see how it locks the arms in position and what's inside
So let's go into the workshop and find out
let's see what's inside and what you get in the box is
The magnetic stand the stand has a magnetic base the base has got a Vee
formed into it but the angles of the very are quite shallow so you'll only be
able to use it on a large diameter it's got two flats so you can hold it on to
any steel with a flat surface you have the on / off lever on the base then on top
of that you have the two arms that can lock into any position
you can fit a dial indicator through the first hole and the screw on the top
gives you some adjustment so you can zero the dial indicator when it's on the job
For the lever type indicator I'll take this out
on the end of the arm is a dovetail and the screw will lock a leaver type Indicator into the dovetail fitting
it'll fit on the bottom of the dial indicator or on the back of the dial
indicator with the dovetail just lock this up and then the screw on the top will give
you some fine adjustment
it's very flexible and once you've locked the thumbscrew it gives you a positive lock
let's try it on the lathe I've just fitted the dial indicator in the sleve this is the fine adjustment
on the bottom you can move it over the
workpiece to where it's needed turn the knob to lock it you can see it's fairly
firm you can rotate the part to do your checks if you need to move it you
can slacken it off and lock it you could probably set it to zero.
without the fine adjustment there we go and then underneath you've
got the fine adjustment you can move it to the zero position do the normal
checks you need slacken it off move it out the way.
The V in the bottom is to
shallow to use on anything that's smaller than about four inches it will
grip on the outside of the chuck and it's solid when it's gripping onto a
flat surface
now if I change this dial indicator to the lever type.
the lever type slides into the Vee on the end
and you use the same clamping nut to clamp the dial
indicator and the lever type in position and here you've got some fine adjustment
so you can zero it that's running out far too much for this dial indicator
if I just touch it on the highest point
you can see I can zero it on there and do the checks I need.
it's easy to move to any position
The way this works, inside each of these arms there's a steel rod which comes
down when you tighten the arm by turning this knob it pulls the cap head through
which pulls in these two bushes with the taper on each end
The end of the rod has a similar matching taper so as you pull the bush in it pushes the rod through
the arm forcing the ball joint on the end to grip on the end of the circlip
you can see it on this one easier there's the ball
The ball is pushed outwards by tightening up the rod
when here's no tension on there you can see
it moves in and out If I apply some tension take the tension off it's loose
tension it up it pushes the ball towards the outside there's a circlip on the outside
so it locks up so what ever position you put the ball in it will lock up and
the same on the bottom one and in that way it locks the two arms rigid
Let me explain how this works with this simple drawing
this is how the magnetic base clamps the arms together this end is the ball with the
fitting on the end for the dial indicator here's a circlip a round one
once the ball goes into the adapter it can't come out this part is fitted to
the aluminium arm and inside the aluminium arm is a steel rod
which touches the top of the ball and the taper so when you tighten the thumbscrew
up the two parts with tapers on are pulled in with the cap head and that
pushes the bar out and locks the ball up against the circlip and locks it in position
and the same thing happens on the other arm and thats how the locking
mechanism works
Well overall I'm very impressed with this it's good value for money
and the qualities there I've put a link to the website where the details of
this video are displayed
Well that's it for today hope that was useful and we'll see you next time on
