Hello welcome to Enots engineering I'm Alan
I todays video we make this hand nut for my headstock handle
the handle was made from a car steering wheel
and on this I used some aluminium knitting needles to make the rivets
I've made the body a little longer than needed
so if I damage the thread in the end I can always cut some off and rethread it
so let's go into the workshop and see how we make it
this is my headstock handle wheel
what I want to do today is make a replacement nut
the way this works this has a cone on the end and a matching taper in the spindle
so as you pull this down it starts to force this to open out
and the outside grips the inside of the headstock
now once you've pulled it down and locked it tight
you have to tap the end with the hammer to release the cone
and what I want you to do is make it easier to use
I did find this which has the same thread will fit on there
the down side to it this is only plastic and
if I start hitting this with a hammer I think it would shatter
so what I want to do is make a similar device that I can use
without having to have a spanner on there
I can do that by hand tighten it up undo it
and something that I can hit the back with a hammer without the plastic shattering
this is what I want to make
M6 thread on a piece of steel bar
I'm going to cut a slot in the end of the bar and insert some aluminium to give me the shape
I've removed the tool post so that I'm not going to catch my hand on the tool
inserted a tap
fitted the hand wheel on the back of the headstock
I'm tapping this M6
you can see how easy it is to do with the hand wheel on
and that's gone right into the end
back it off
take the tail stock away
clean the swarf out the tap
I want to change the tap to the second tap
because I've already tapped the hole I'm not going to use the tailstock tap guide
this will follow the original tap just clean out the thread
that's gone right down
I've just put a centre on the very outside edge
so that I can re align this later
so this ends finished turned it round
and I want to cut about 25mm off the end
so I'll put my parting off tool in
okay of set the centre drill 5mm from the end and on centreline
and I want to drill a hole there and a hole 10mm along
we have two centre drill marks there these countersinks on here
I'll be using for rivets
so the next thing I need to do is drill a hole straight through
and what I've done is just turned to part round use the drill to the line up
so I know I'm in the right position and now I will just countersink those two holes
I've put the drill through to get the the bar 90 degrees
so I can now mill a slot through the bar
I've marked out the shape of the top of the nut
on a 10 millimeter piece of aluminium plate
then I use the bandsaw to cut the shape out
take a knitting needle this one's number six just push that through the hole
okay here's the finish item here's the head stock hand wheel
this tightens up
and to undo it undo the nut tap on the end
and this comes out
well that's it for today hope that was useful hope is interesting
and we'll see you next time on Enots engineering
