Where to get 32000 grit sanding supplies/pads?

[fudo133]

<abbr class="published" title="2014-05-29T23:46:56+00:00"></abbr> Hi there everyone,
I was wondering if anyone had any ideas as to where i might be able to get extremely fine grit sanding pads?

I've got all the micro mesh grits going up to 12,000, but if its possible i'd like to try out the others. 32000 is the finest that i've heard of, and despite reading about a lot of people on model making and airbrushing forums having it, i'm afraid i'm turning up blanks in my search for some online.

Good luck.

No connection except as a occasional purchaser.

Chromium, Aluminium, Iron and Copper oxides are sold as "honing compounds."
The nominal particle sizes are in the range of 0.25 (eg Al) - 0.5 (eg Cr) microns.
I've been told that this is the approximate equivalent of 20k - 35k.

As polish, they leave a surface so finely scratched that it isn't resolved as such by the human eye. I am satisfied with Cr honing compound, laced with Al.
For example: Lee Valley Veritas Blade Honing Compound # 05M08.01

It is common to heavily streak a hard leather strop or a strip of cracker box cardboard and use that surface.

The ferromagnetic properties of iron oxide (old computer storage disks and audio tape)
become useful with at least an order of magnitude smaller size.

I've been working on an antique japanese lacquer shrine case on commission for someone and have been given the job of trying to repair some broken and chipped areas of finish...i'm using shellac rather than lacquer, but i'm not great at french polishing, and i dont really have the time required to master it. Thus, abrasives are the key i think.
Just last night though i finally found a source for sanding pads up to 60,000 grit though!

[soundman]

have you thaught about sanding into the mid hundreds or may be low thousands and then misting over with meths.

It wrks with nitro.

the solvent.....realy fine mist and only just enough....melts out the scratches from the last grit of paper.

cheers

I've not really! I might give it a shot.
Currently this is where i'm at with 12,000 grit sanding with micromesh...good...but not glossy enough.
I also sanded through the finish in a few places, but then, this did only have 4 or 5 coats of shellac on it, and it was just a little test run.

curious minds wonder if you have agreed with the antique's owner that the repairs will be using shellac and not what is probably Urushi lacquer

If you are going to use shellac, I think you will need many more coats than 5 or 6 before you start polishing

[fudo133]

Oh don't worry, we've agreed, its just that shellac can offer an extremely high gloss like lacquer, and unlike lacquer its quite reversible and relatively easy to strip off should the owner or someone else down the track wish to have it done properly.

Likewise i'm sure i'll need more than 5 or 6 coats....i was thinking more in the region of 30-60 to build up something similar to all the transparent layers of colour you get in old black japanese lacquer as a result of sun damage and the effects of time in general....

The piece i did with only a few coats was just a test run to see whether micromesh would be able to polish the shellac properly.

it might be worth investigating some of the car polishing compounds -- I think the "grit" in some of them reach into the 25+ thousands

[soundman]

here here....some of the current auto polishing compunds are just spactacular.

Its not just the grit size, but the shape and regularity of the grit.....the current generation the grit particals are near spherical.

I've been using a previous generation compound in a medium grade on acrillics and they come up gleaming gleaming gleaming.

there is a finer grade, but it is pretty well pointless.....if you use it on cars you have to be carefull not to get it on the rubber, because the abrasive is so fine it bet into the pores in the rubber.

Chat with your local auto refinish supplier.
