I'm kidding. Of course I know how. I just wanted to watch the collective blood pressure of the knowlege snobs penetrate the ionosphere. Why is it that people get so upset over newbies asking their questions in this forum?
If new posts covering familliar territory pop up frequently that's a good thing. It's a sign that increasing numbers of people are taking up the art that inspires you and me. The more luthiers there are, the more experience and knowlege there is to share. Instead of condescendingly tossing a link to a general section at someone and acting like they're lucky the didn't get smacked for asking, why not find the actual answer, post a link to that, and offer the new user some suggestions on how to navigate this website and others related to the topic?
I'm sure many still-learning-luthiers, I'm one, work on borrowed time. Sometimes it can take a while to navigate a site that you're still getting familliar with. There's a funt of knowlege here, but I can attest to it being difficult to locate at times. Is it that bad for someone who gets lost in search of answers to ask for directions?
Learning together is easier in a relaxed and friendly community. So what if there's a few extra posts on the message boards? All the more to read through while you kill time. I say if you've got a question; ask it.
Now, about those bushings, I have a little technique, one you won't find anywhere on this website, that makes it easier to get them out. 1) Score the finish around the bushings with a sharp razor blade or exacto knife. 2) Remove the bridge. 3)Take the bridge assembly off its adjustable screws. 4) Place the bridge ontop of the bushings so that their holes line up. 5) Thread the adjustable screws through the bridge and into the bushings. 6) Turn them one full turn. 7) Place a piece of soft cloth under the bridge and something thin and hard for a prying surface over the cloth. 9) With a heavy duty screwdriver or other lever, pry against the bottom of the bridge.
The bushings will pop right out unless they're glued in. If you suspect that yours are glued in, insert the tip of a hot soldering iron into the bushings, hold it there for a few minutes to melt the glue, and QUICKLY repeat the steps.
