But it's just as well she didn't use red first, eh? :eek:

The girl reckons black and blue if I,m not careful :eek: As I said I'd die a happy man.

Agreed there is no need for a finish after micromesh, but is there a difference between the final micromesh finish; and that achieved by 400 then EEE?

I believe so Neil, it may sound funny but my fingertips are pretty sensitive and I can tell the difference with the smoothness of the surface between 400 and EEE and a 12000 MM finish. Finishing with EEE will give you a brilliant finish and that is the first thing I use on CA finishes but with all CA and acylics I finish with Dilux on a buffing wheel and buff with the grain direction.

I don't think so, apart from the obvious "mechanical" one... if you haven't removed 100% of the previous grits' scoring then EEE will bring the rest up nice but enhance the scratch.

Whereas working through the meshes may polish the scratch out, at worst it will reduce its' impact.

I guess a good magnifier would decide for sure one way or another, but whose vision is so good that they could tell with the naked eye? Certainly not mine... but I must admit I suspect that age is having its' effect...

I agree with what you say there Skew, they say 12000 MM scratch pattern is not visable to the eye

Now I know that's beyond me. The callouses on my fingertips make it hard for me feel any difference between raw and dressed timbers.

Well... not quite that bad, but not much better either.

Comes from not using backing when hand-sanding on the lathe... I honestly can't remember the last time I looked at my fingertips and saw clean pink skin, let alone fingerprint whorls! :eek:

My word lots of very fine particles holding in suspension there. Are we getting amongst the sub .05 micron level?

Hey Tas, 8000 Micro Mesh is around the 2 micron level if I remember the chart correctly.
