From TRADE SECRETS - VOLUME 43 (Edited by Dan Erlewine) Article talking to Tom Jones www.tvjones.com
Jon Paterson [a violin maker - ed] taught me how to prepare maple for finishing by sizing, scraping and burnishing, rather than simply sanding it prior to staining. The technique I use is as follows:
1) Sand the flame maple (or other wood) with 320-grit Stikit andpaper from Stew-Mac. Jon prefers to scrape the wood prior to burnishing for a more reflective surface.
2) Wipe, blow and vacuum away the dust, and then size the wood with Knox unflavored gelatin from the supermarket. Put 1/4 teaspoon of gelatin into a baby food jar and fill it with water. You now have a weak mixture of hide glue! Heat it until it's hot, and then use within 1/2 hour. Wipe or brush it onto the wood and let it dry.
3) Next, after the surface is dry, eliminate the "fluff" on the wood sufrace by sanding with 600-grit Stikit paper. Jon prefes scraping.
4) Burnish he wood with a hard polished object such as a polished stone, ivory, bone or ironwood.
5) Now the surface is ready for the finish. Burnishing the wood makes a more reflective surface when viewed through the finish. A sanded, unburnished bit of wood tends to have a slightly matte finish. I repeat the gelatin process several times if I think the stain might look blotchy, especially at the neck heel.
So there you go, what do you think (and no jellycaster jokes)
