Another use for that forgotten vertical slide.

[DavidA]

Anyone tried this technique ?

Could be handy for hogging out spokes etc.

Dave.

Note, the music is rather annoying.

Seems a long winded way of making it , simple turning job as I see it .

Those boys are in serious need of a simple CNC  mill

I assume the "college" pays for the raw materials!

I second that

Who needs CNC when you've got 1YSC (1st Year Student Controlled) Cheaper, and easier to replace if things go wrong 

What I want to know is.... what IS it they were making? And what's it for?

It's a support for a clock ballence wheel to let the wheel outside of the plates , to allow it to be seen .

I thought they just made the swarf for the heat bath at the end.

Whilst I agree that the job could have been done just as easily on a milling machine, it does show how you can add another axis to your lathe. And maybe the whole point was to illustrate a different technique. 
The clock making fraternity do like their 'glued on' work holding.

Does anyone know if the method used was once in common use amongst clock makers ?

Dave.

[Joules]

Yes, but they used to use wax chucks in place of superglue.  My mentor taught me how to use a wax chuck and I keep a couple of sticks of sealing wax handy in the event.

I experimented a few years ago using special thin wax film to bond panels that I was CNC machining. Never did get a satisfactory result, it often letting go even with very light cuts, and of course any heat and it melted 

Then I went on to double sided tape, which is better but suffers two drawbacks. Firstly removal - hard to pull a thin sheet off without bending it and also hard to remove the goo from the part and platen. Secondly when cutting all the way through bits of the goo would gum up the cutter retaining chips.

I haven't yet tried super glue but I remember Steve (VTSteam) gluing his tractor cylinder head to his mill table for machining quite satisfactorily.

Nice concept.... with slight redundancies...

Damm the kids today even have to sit down while machining.... I really am loosing touch.

Yes.  There is nothing more character forming than spending eight hours a day standing operating a lathe that is a few inch below the correct height.

My lathe was setup so I can sit down while working due to a bad back but I still stand to get measurements or when I need to make critical adjustments

We always used melted orange flake shellac to hold watch and clock parts on wax chucks, then dissolved the residue in denatured alcohol.  Super glue is the new way of doing it.

[howsitwork?]

Andrew et al

Superglue works well provided surface is clean and of reasonable area

To get it off afterwards sit it in a bath of nail varnish remover overnight in sealed container ( or just enjoy the fumes whilst you finish your nails....

[nrml]

This is a very neat way of using superglue for workholding.

The video is a little bit long winded (no offence intended towards the guy who made it) but it is well worth a watch just to see how effective the technique is.

[awemawson]

Interesting 

Is there anything special about the green masking tape he was using - never seen that before 


(I was rather concerned about the amount of sawdust in his Z-Axis screw)
