Working w/Purple Heart and Paauk
Just pick up a small piece of each this morning.
I'm planning on making a few small desk items with it. Pen & pencil holder, bus card holder and such. I've never used this wood before. Any tips on working with it, specifically cutting & routing it. I'm just planning on gluing it up with orig Titebond instead of trying to shoot some 5/8" brads, since they are both pretty dense woods. What is a good choice for a finish which will help the woods retain their great colors? ThankX again, Ron |

Be careful of the padauk sawdust, its known to be a severe allergen and/or
toxin. Milling or sanding it throws up A LOT of very fine reddish dust that settles everywhere. I suffered a pretty severe chest infection after working it in a closed-up shop once. Dust collection and a respirator are in order. I've read that oil-based finishes will cause padauk to turn darker brown faster. I've also read recommendations for water-based urethanes. UV protection is the key to preserving the color. -jbb "Ron Angel" wrote in message news:Wd4Yc.249943$eM2.156208@attbi_s51... Just pick up a small piece of each this morning.

I'll second that one, and then some. I resawed and milled a bunch of padauk to
make some fine boxes. Had a 2hp DC on the BS, plus an air cleaner and wore a mask. In the end, the BS still ended up red. Made these perhaps 4 years ago, finished with WB urethane. They are not in direct sunlight, and have held their color and depth. I did use Titebond, but most joints were either dovetail or finger. Suspect that a mechanically weaker joint may well need a different glue. I seem to remember a spacer that broke loose, even though plenty of long-long grain area and little strain.

I have a musical instrument company, and I work quite a bit with both
Purple Heart and Padauk. Absolutely, you need good dust collectors and respirators with both woods if you're doing any significant amount of sanding or sawing. Padauk makes piles of fine orange dust, which gets in everything and is bad to breathe. Purpleheart makes very tiny little splinters which can be nasty, almost like catcus barbs. Be careful when handling rough boards, and make sure to completely smooth off all edges on your finished project. Gluing both woods can also be a problem, because they both have a very high content of resin, which gives them the bright color. It's like the wood has been soaked in wax, so many types of glues just won't get a good bond, regardless of your preparation. I don't trust Titebond with either of these woods. When you need to depend on the strength of the glue joint with either of these woods, I recommend a good epoxy. The best I've found is Smith & Co.'s All Wood Glue (an innocent sounding name). It's blended specifically for gluing resinous hardwoods, and works very well. I hope this helps. Bruce Johnson GerryG wrote in message . .. I'll second that one, and then some.

About finishing Purple Heart and Padauk;
Both of these woods are almost self-finishing, because of their inherent high resin content. The bare wood can be polished up to a gloss, which in many cases is all you need. When I use Purple Heart and Padauk for guitar fingerboards, I bring them up to a gloss, and then give them one or two light coats of a hardening polyurethane "oil" finish. I use Stewart-MacDonald's Fingerboard Oil, which is a special blend for instrument use, but Minwax or Olympic Oil-Based polyurethane will work too. The finish will significantly darken the color (although it's still quite beautiful), but then it will brighten up somewhat over the next week or two. By the way, here's my favorite technique for smoothing woods hard like Purple Heart, Padauk, Ebony, etc. up to a gloss: 1. Do most of the shaping with sharp files, not coarse sandpaper. It's faster, and doesn't leave deep random scratches. Finish up the smoothing with a Smooth or even a #2 Swiss file. 2. Fine sand with 320 and 400 Stearated paper on a rubber block, only in the direction of the grain, to remove the last file marks. 3. Finish up with ScotchBrite-style woven abrasives. I usually use Green, then Gray, then White. Use them over a rubber block, with pressure and elbow grease, again only in the direction of the grain. The White Scotchbrite will take the wood up to a mirror gloss. You can go crazy trying to polish ebony with fine sandpaper. I understand that this is because the ebony dust is quite hard and abrasive by itself, and will embed itself in the sandpaper, cutting coarser than the sandpapers' abrasive. I think the Scotchbrite works so well here because the open weave allows the dust to get out. I hope this helps! Bruce Johnson "Ron Angel" wrote in message news:Wd4Yc.249943$eM2.156208@attbi_s51...
