sandpaper on glass- an idea- vaccuum, suction?

[ali27]

Guys,

A few times I have flattened my plane sole
on glass with sandpaper. I use some glue spray
to stick the paper on the glass.

I really hate the smell of the glue. I think it
is bad for the lungs. Also you need to clean
the glue after removing the sandpaper.

Using wet and dry sandpaper with water under
it to stick it works well, but the plane sole and
the frog start to rust almost immediately because
the water is touching those as well.

So I was thinking about drilling a lot of small holes
in the glass plate. Then putting some bag with
many small holes as well under the glass plate. Use
a small pump to draw away the air between the glass
plate and the sanding paper and this should make it
stick without making any mess whatsover.

If you want to remove the sanding paper, just pull
back some air and the vaccuum is gone and the paper
lets go.

Something like this:

I doubt if the vacuum will hold the W&D really flat but it is an interesting idea.

However if instead of using water you use a really thin oil then I your problem goes away. The life if the paper (it isn't usually paper) may be shorter but no rust.

That idea 'sucks' :lol: as the concept of drilling lots of small holes in glass isn't one I'd contemplate in a hurry. Use the self adhesive 3M PSA films from Workshop Heaven...much easier and a little dribble of white spirit is all you need to remove the old adhesive - Rob

Pipped at the post by the bloke!

PM me your adress Ali and I'll send you a sample, it's life changing stuff.

I second (or third is it?) that the PSA is the thing to use.

Didn't realise that white spirit was the thing for getting them off though. I'll have to bear that in mind.

I've tried various liquids to remove the glue film (meths, paint brush cleaner etc) and white spirit 'ordinaire' together with the use of a nylon scourer seems to work best. I've not tried acetone but I suspect that would evaporate too quickly. After the white spirt, wash in hot water and then clean the glass thoroughly with a bit of Mr Muscle window cleaner and polish with a soft cloth...then you're ready for the next application of the films - Rob

Ali you really have a bad case of the crazy sharpening bug!
Don't let us talk you out of it - if you get around to doing woodwork you won't have time for it anyway!

Simplest way is to wet the paper and the glass with white spirit or light oil.
That will hold it down just enough and at the same time help with the sharpening.
You may need to keep a finger on the edge until it has been pressed nice n flat to the surface, as you use it. Cloth backed paper tends to curl a bit, paper paper is better.
Helps if you store it flat in between boards when not in use. No I don't know how flat the boards should be!

PS NB glue and/or sticky paper a bad idea, as Rob explains above.

Why not buy some loose grits, they come in all sorts of grit sizes. I use a light oil like WD40.

Loose grit also abrades the glass plate. So it does not remain flat.
