This is a sheave for the single-sheave masthead castings used on old Hobie 16s. Hobie no longer sells this part. My design has a slightly deeper groove profile than the original, with more durable flanges. It should be less prone to cracking.
Two design files are available:
H16_Old_Masthead_Sheave_with_bearing is designed for a bronze plain bearing with the following dimensions:
- 3/8" ID
- ½" OD
- 3/8" length
H16_Old_Masthead_Sheave_no_bearing runs directly on the shaft without a bearing.
Both designs require the following parts for installation:
- 1 ¼" long #3/8-16 machine screw
- #3/8-16 nylock nut, preferably low-profile
I printed mine out of PA6-CF for improved abrasion resistance against the wire halyard. PETG could be used, but would likely experience increased wear in hot weather.
