I am wanting to do my own veneer purfling layups.Can you guys tell me what glue to use and how you process to keep it flat and consistant? TIA |

Keith, I have only done this once, but my method was painless and effective. First, I made pieces of veneer for the purfling (I resaw my own and run it through a thickness sander). The purfling veneers ended up 6" wide by a few inches longer than my sides by .030" thick. I also tried some that were about .015" thick, and those were nice too. Then I took the material that I used for binding and cut that into slabs 6" wide by a few inches longer than my sides by however thick they needed to be to make .25" after I added the thickness of the purfling veneers. Then I slopped on some Titebond III, which I normally don't use, on all of the veneers sandwiched together with the binding slab on top. I stuffed it in my vacuum press and left it overnight. After 24 hours, I sliced strips off the binding/purfling slab that were a hair over 1/8" thick and ran them throug the thickness sander to get rid of the bandsaw marks. Then I stuck them in the side bender, and everything came out beautifully. The Titebond III seems to work well in the bender --- it gets pretty flexible under heat and moisture, which allows the wood to bend, but not so flexible that it comes apart. The results were very good. Hope this makes sense. |

Thanks Kelby that gives me some good ideas. Did you use a sled to sand the veneers? |

Keith, I used a sled. When you get down to 15-30 thousandths on my sander, the drum starts sanding the feed roller without a sled. (Speaking of which, I need to get myself a new feed roller . . . .) |

Another thing you may want to think of to get veneer flat is Nordy's Veneer Treatment, sold at Rockler in the US. Rockler part # 58446. I'm not sure if it is pure glycerine (which you could probably get at a lot of places), or if there are other additives. I had some brittle, potato-chip textured, quilted maple veneer that was intended for a furniture project. I soaked the veneer in that stuff, and pressed it between nylon screens with layers of newspaper and particle board on both sides. I changed the newspaper a couple of times, once a day later, and then again 2 days later (to make sure I didn't get mold.) The veneer ended up flat, and almost leathery in texture - the brittleness was completely gone. It worked perfectly, and is now part of an entertainment center. Dennis |
