Q & A—Dust collection/air purifier systems.

• Several brands of air purifiers which pick up the smaller particles were dis-cussed.

Presentation--Panel discussion on sanding by

Art Jalbert, Tim Roach, Mike Grady, and Jim Silva

How do you get to the point that you are ready to apply the finish and not have

Scratches Show up?

• JS--better tool technique means less sanding. Think of your last clean cut as the be-ginning of the sanding process. Always use sharp, sharp tools. Don't hesitate to use a French curve cabinet scraper to get a final finish. Start with low grit (100) and then move up through the grits--starting lower ultimately results in a faster sanding |process

How do you choose the sandpaper that you use, what sanding tools do you use ? • TR--buy of bag of Klingspor scraps. They start at 60 grit. Sand on the lathe, using

both forward and reverse for every grit. • MG--uses Norton or 3M (Home Depot) sandpaper. Use a thin sponge layer

for padding between the folds of the sandpaper to have a better grip. Cut the sandpaper into strips and label them. Brush off clogged sandpaper and re-use it.

• AJ--you definitely need more light when sanding and more focus during the sanding process than during the turning process. Sand on the lathe and then cross-sand for each grit

• Al Barbour--dust off the piece and check it with a magnifying glass. The speed of the lathe should be slow, 200-300 rpm depending on the size of the piece, to eliminate heat build-up and surface checking

• JS--the pressure with your hand should only be moderate so that your hand doesn't get hot--back off your pressure if you feel heat. Keep moving in a random orbital pat-tern when possible. If your lathe doesn't reverse, hand sand in between switching grits.

• TR--power sand to 180--when you power sand, have the rotation of the power sander opposite the rotation of the lathe. Use an angle grinder or 1/4" drill with a soft or medium head pad. Try the scalloped disc pads to avoid dig marks or a 6" random orbital sander for big pieces--pneumatic sanders are better than electric

• Peter Haney--David Ellsworth recommends a 6" round soft sanding pad and hand sand off the lathe. Peter uses a triangular oscillating sander with 1/2" foam sanding sponges and sands off the lathe

When do you change grits? • MG--think of sanding as a process for getting rid of the "damage" that you have cre-

ated on the wood from tool marks and other irregularities. The first grit, 80-100 for bigger pieces, is to repair the surface. You are finished with a specific grit when a uniform scratch pattern appears. Wipe off or blow off the piece and then examine under good light. If you have a uniform scratch pattern, then move on to the higher grits where you are refining the scratch pattern. By the time you get to 320-400, you shouldn't see any scratch pattern.

• Mike Gould--as you move up the grits, increase by no more than 50% of the previ-ous grit. Wipe off with mineral spirits to view the scratch pattern and raise the grain. JS--give a quick fine mist of water to raise the grain after 400-600 grit. Let it dry for 15 minutes and then go back to 220 grit and you can move forward quickly back up the grits.

Do you use sanding sealer of some sort as part of the process? • TR--For a "piano or guitar" type finish, on open grain wood, use a grain filler in a similar

color then sand. Apply 2 coats of boiled linseed oil and then sand it back off. Then use 4-6 coats of water based shellac and sand it back. Then use a water based spray lacquer for 8-10 coats. For smaller items, try EEE-Ultra Shine Polish followed by Shellawax liquid (available from www.packardwoodworks.com or Craft Supplies)

• AJ--try sanding 100 to 150 to 180 to 220 then apply a coat of varnish. Then wet sand it with varnish cut 50/50 with mineral spirits until the finish is dull and then wipe it off. The pur-pose of this step is to pack sawdust into the imperfections.

• TR--on some projects, for a "piano or guitar" finish, sand up to 1200 using mineral oil. • Get higher grit sandpaper at an auto body store

How do you approach re-sanding a piece years after it has been finished if you need to re-

pair or replace the finish • JS--get most of the finish off by gently scraping, using Abranet screening which does not

clog (TR) send the piece to a "Dip and Strip" furniture shop, or sand on the drill press. When you use a drill press with a soft foam pad with a 3" disc or scalloped disc, you can see what you are doing more clearly than sanding it on the lathe and the dust collection is eas-ier. A Velcro Disc Hand Holder (#129401--Hand Holder-www.packardwoodworks.com) can be used with 2" or 3" discs

• TR.--use tool extensions for reaching into tall pieces such as a "broom handle" type or com-mercial extension. 3M Scotch Brite Pads which can be purchased in the finishing depart-ment of auto parts stores can be used wet or dry and are used in between coats or before ap-plying wax. After your last coat of finish, apply Renaissance Wax to minimize finger prints and buff with a cloth

• JS--Mahoney's Walnut Oil is a good food safe finish. (WTF), another food safe finish, dries in 5 minutes between coats

What are some sanding safety tips that you want everyone to know to be safe? • Pay attention

• Take off the tool rest before sanding

• Remember that wood dust is explosive

• Remember that wood toxicity is cumulative, especially with spalted wood,

• Wear a mask, respirator, or helmet with an air flow

• Do not wear a sanding glove

• Use paper towel, not a rag, on a spinning lathe

• If you must use a rag, fold it into a square--do not wrap it around your fin-

gers

• Wear eye protection

• Wear a turning smock to avoid contaminating your house with dust and chips

• Boiled linseed oil will spontaneously combust--flatten out towels to dry

• Do not reach your hand into taller piece (or any "closed" piece) while it is spinning on the lathe
