hello welcome to Enots engineering I'm Alan
Today in the work shop I'm looking at the lamp on the milling machine
This is the lamp I've taken off
This part bolts to the milling machine head
and then we bend this part round so the light shines o the work your doing
and what I find with this is having to bend this right around
What happens is it eventually ends up coming back down and pointing at the table
So what I want to do today is replace the flexible part but keep the two ends
with a mechanical joint which will do the same thing
But more effectivly
So lets go into the work shop and see how we do it
All this is in here is a flexible cable protector
Do away with the flexible part
And make a smaller unit that goes between the base and the bulb holder
So I can move it and its kept in the same position
These are the four blanks
we have a female one thread in the end and ball on the end
Male one that will have a thread cut on it and fit inside there
And then we have two smaller ones
That will have threads put on the end
These go inside this and also inside that
It needs some flats putting on the threads it has flats on the hole
The same as that one it has two flats on the side of the hole
So once I've put the flats on the thread That will fit in there
Take the part with the plain shaft 10mm diameter
And use a die in the stock here a 10mm die to cut the thread
Because of the spherical on the end I'm pushing it right in
Behind the chuck jaws and bring it forward
And I"m about 5mm in past the jaws
So I can cut the thread on this
Here is the 10mm die this one is 10 x 1.5mm
Thats held in the stock with the handle
That slides on to this bar which is held in the tail stock
and this bar has a hole in the end so the die can go right over there
and the part can go inside
That will go right inside so I can go the length the length of the part
That slides on there I will get about 30mm movement on there
and then if you have a longer bar it will go inside
Bring this up lock the tail stock
I have my expanding mandrel on the back
and with the handle on here turn it around
Start to produce the thread
Give it some oil to help the die
Theres the thread
Now I just need to hold this in the vice
and thread the last 3 turns
because I can't go any closer than the front of the chuck
Now this one will fit in the centre of that one
So I just need to finish the thread off to the face
And those two should lock together
I just held it in the vice with some lead jaw protectors
That should fit on
One of the jobs I need to do is make a little locking ring on here
so when you adjust these you can lock the thread
Well that's it for today
I hope you enjoyed it we will continue this in the next video
Thanks for watching and we will se you next time on Enots engineering
