Sanding speed?
Heat is your enemy when sanding. Slower means cooler, so sand slowly and
softly to preserve the surface of the wood against burnishing and the sandpaper against degrade. Not to mention your fingers against blisters. Green wood is too tough to sand properly, so I give it a run with 100 or 120 - machine sanding, than let it dry before going on. Saves me a lot of frustration and clogged paper.

I'm hoping someone will do the "final chapter" and enlighten me about what speed to do the [final] sanding at. I used to do it at about 3,000 rpm but slowed it down some as my fingers got too hot. Any difference in speeds for dry hardwood and green wood? |

You might want to get a powered sanding device. I use an angle drill that spins at 1300 forward and reverse. This little guy has saved my hands and has made my work as smooth as a baby's bottom. If you are worried about expense, you can go to Ebay and do a search on "Close Quarter Drill" and you will be able to get a brand new one for about $30. Then go to Industrial Abrasives web site and get a hook and loop disc holder and hook and loop discs (in grits of 120, 220, 320 & 400) and you will have a small investment of about $60 in the equipment and paper and your work will be 100 times better for using the powered sander and your fingers will not get burned and your pieces will not get heat checked. I wish $60 would solve so many other problems! Ray "Bart V" wrote in message ... Hi folks, There have been a lot of postings about turning & grinding speeds recently.

If you are feeling that much heat just imagine how hot the wood is. The
heat can cause heat checks, tiny cracks, that will detract from the appearance. If your piece gets hot you are sanding too fast. You can also try one of the self-powered sanders, no heat generated but does not sand very well in the bottoms of bowls due to slow speed.....Ralph "Bart V" wrote in message ...
