5" straight fletching arrow jig

thingiverse

This jig is a modified version of thing 578962, viewable at http://www.thingiverse.com/thing:578962. I made this mainly for straight-fletching long shafts with five inch feathers on my slingbow, but it works just fine for other bows and arrow launchers too. Key changes include: The tool's size increased to support five-inch feathers. Base arm hinges were extended and joined for added strength. A loading wedge was added; insert and push the wedge from the backside of the arm into a slot to open up the slot and make it easier to load feather onto the arm. Version four of the base features removable tapered nock index inserts. Use needle nose pliers to insert, push, and twist these inserts at the desired indexed nock angle in the base. Two nock inserts, one with and one without a slot, are provided for use. The arms have different center relief groove sizes: five sixteenths of an inch for about "312" and eleven thirty-twos for about "360." Straight fletching is supported by the arms only. Print Settings Printer brand: Ultimaker printer: Ultimaker Original Rafts: Yes Supports: Yes Resolution: 0.150 mm layers / 0.5 mm lines Infill: 33.3% octagonal Notes: The white parts in the photo are Taulman 618, while the green parts are Oregon brand trimmer line printed on Garolite at a nozzle temperature of two fifty C with a raft and 0.60 mm thick fillet brim; these settings provided perfect nylon to bed adhesion with this material. Build chamber was set to thirty C. This application suits nylon because it is somewhat flexible, strong, and resistant to fletching adhesive. Nylon however might be the most difficult material to print well. The support structure used (though not absolutely necessary in nylon) aided in printing by keeping the overhangs of the base hinge arm screw holes straight. This jig was designed using several different tools and applications. To combine existing mesh files with new geometries, Blender boolean operations were utilized; pushing and pulling surfaces created with Wings 3D; Netfabb Studio generated new parts; and Geomagic added more components. Editing mesh files is a process which usually requires patience.
