micro mess
Bruce Wiseman
>In the I can never leave well enough alone catagory: I was sanding a cherry bowl and decided to use the micro mesh sand paper. Near the rim edge somehow the grit came off the backing and into the wood leaving a gray streak around the rim. Not the look I was going for. What did I do wrong? The 3200 grit cloth has a big stripe where the material is gone and there is only cloth backing. Instead of mirco mesh I have micro mess.

>Micro Mesh melts readily. The higher grits melt even easier than the lower ones. As you discovered, never, ever let the mesh rest for even a single moment on an edge or a messy result is your reward. Most of us probably have a melt track or two on the higher grit pieces, but with every batch of new micro mesh they appear on a decreasing basis.

>I'm glad you posted your problem Bruce. I was just going to use the mesh for the first time and would have done the same. Thanks to your post I may avoid the problem this time.

>It melted Bruce. To much pressure and or sanding in one spot to long over heated the glue holding the grit. It then cooled and dryied on the wood.
Lighten up.
Go back with some heavier grit sandpaper to remove the streeks. Or try some solvents.
Happy turning.

Timely advice :)

>Hi guys,
I just this last weekend bought a kit of micromesh and have not even taken it out of the box yet. I feel certain I would have melted it as I tend to be a bit heavy handed with the papers.
Thanks for the heads up, you've saved me some frustrations!

Not ashamed to use a 60grit gouge in Apex, NC...

>Besides the good advice about moving the micromesh, you should also slow your speed down. Take into account the outside diameter of your piece. The outside diameter of bowls is your widest point and will therefore be going at the fastest RPM. Also, a lubricant will help. I only use micromesh for plastics, corian, etc. What works best for me is a large plastic container with water and all the grits inside. The water acts as a lubricant and rinses the micromesh off afterwards, too.
