Help with making a 135 Degree Angle

djavaisadog · May 10, 2019, 11:10pm

For part of my intake, I want a 90 degree gusset moving linearly, which i plan to achieve with a worm gear, but I need to create a 135 degree angle to attach the axle to the gusset. The way I thought of to make the 135 deg angle was a hinge, but I’m not sure how to secure it so it won’t go back/forth. If you have any ideas on how to secure the hinge or create a tight 135 degree angle otherwise, or even some way that I can get around having to make that angle, let me know.

CAD render below for clarification.

“45-Degree Gusset (6-pack)” is a 135-degree angle. I’ve never heard of anyone securing a hinge, but you can try combining this with other gussets to screw your 90-degree angle on.

Maybe cut a c-channel into two 2x2x1, and attach them between two gussets?

Oh, I didn’t even realize that the 45 was a 135. Bad naming I guess. Thanks!

vex makes a steel hinge, which is exactly what you want to use (it can take a LOT of weight), along with a 45 degree gusset to help keep it in place.

Vex sells 135 degree gussets

Why is that better than just using the 45 degree gusset if it doesn’t need to take a lot of weight?

it depends on the way the force goes. If you’re trying to create something where the force goes across the flat portion of the gusset, for example in this drive base, you’re going to need a lot more support

However, if you’re using gussets where the force goes vertically, such as in this mogo lift you can get away with having a lot less bracing.
