5" straight fletching arrow jig

thingiverse

This arrow fletching jig is a remix of thing 578962. See http://www.thingiverse.com/thing:578962 I made this jig mostly to straight-fletch long shafts with 5" feathers for my slingbow but it works fine for other bows and arrow launchers too. Changes: Enlarged tool to support 5" feathers. Base arm hinges extended and joined for greater strength. Loading wedge added. (Insert and push wedge into slot from arm backside to spread slot open and ease the loading of feather into arm.) V4 base uses removable tapered nock index inserts. Use needle nose pliers to insert, push, and twist the insert into the base at the desired indexed nock angle. Nock insert with and without slot is provided. Two arms with different size center relief grooves provided for ~5/16" ("312") and ~11/32 shafts ("360"). Arms support straight fletching 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: White parts in photo are Taulman 618 and green parts are Oregon brand trimmer line. Both printed on Garolite at 250 C nozzle temperature with Kisslicer raft AND 0.60 mm thick fillet brim, which are both necessary to achieve perfect nylon to bed adhesion with these thick and blocky parts. Build chamber was heated to 30C. Nylon is perfect for this application because it's somewhat flexible, strong, and resistant to fletching adhesive. It is, however, perhaps the most challenging material to print well! Support was useful (but not absolutely mandatory in nylon), for the overhangs of the base hinge arm screw holes only. How I Designed This It's always tricky and time-consuming to edit mesh files instead of solid models! Nonetheless, I used Wings 3D to push and pull mesh surfaces and Blender boolean ops to combine with new geometries created in netfabb Studio and Geomagic.
