So far i havent found any guitar binding scrapers that can be printed anywhere and im not willing to fork over +50$ for a binding scraper, so i've designed my own!
it's a somewhat simple designe with some good additions to help you make the binding lines sharp and nice looking. I've designed two scrapers for the job, one to help you clean the top of the binding and one for the side, you can find them both in my profile or here (insert link to it).
Material:
All you're going to need is a 58mm wide utility blade, 3x M3x10mm bolts and M3 2x8mm bearings with a 3mm hole.
I have printed my parts out of PETG with a layer height of 0.16mm, so keep that in mind if you're going to print it out of anything else, since there might be a tolerance differance's.
Assembly:
- First just in case tap the screw holes on the side and bottom with a M3 thread cutter to make them fit the screws, this should be way more than enough to hold the blade, if not i can update the model to include brass thread inserts.
- Add the bearings to the bottom using the M3x8mm screws. Note: These are used to guide you along the edge of the guitar, you can also use one to sneek up on the cut and switch on what side the bearing is, depending on your preference of in what direction you like to scrape, or no bearing at all if you like to live your life on the EDGE.
- Insert the blade in to the gap and add M3x10mm the screws till they touch the blade, now you can messure the stick out from the top edge to the tip. and tight it down to a somewhat reasonable torque. Note: you can angle the blade to get the desired effect, for example if you want to have a nice fade between the paint edge and binding or a somewhat sharp transition.
- Just in case you can add a layer of masking tape to the bottom of the tool to prevent it from potentially scratching the paint. make sure to have cuple of coat of lacquer on the paint so you can still polish it out in anycase.
After you are done using the scraper, you can tuck the blade in so it's safe to handle it, so that you don't get cut when you inevitably rummage through the messy drawer.
