build a barn door tracker
The most important part of the barn door tracker is the radius of the curvature - the distance between the drive bolt and hinge. this is determined by the thread size of your drive bolt and will control the rate at which the top board raises for every turn of the drive bolt.. I give you 100% credit for accomplishing this! i have to say me and the hubs tried doing the same thing figuring out a way to make our barn door hardware without spending tons of money.. A personal project to build a lightweight barn door tracker. explores how to connect lego parts and non-lego structures in non-destructive ways. includes an optional motorized crank using a mindstorms ev3 brick, 360 panorama turntable, and building instructions.. Stand the door on the shim and, with a helper, lay the wheels on the track, noting the correct locations for the final lag bolts from the strap to the door. drill two holes in each strap (8 total) to 1/2" for the 5/16" lag bolts.. .
I give you 100% credit for accomplishing this! i have to say me and the hubs tried doing the same thing figuring out a way to make our barn door hardware without spending tons of money.. The results your barn door tracker provides, however, will vary based on the accuracy of your materials fabrication, hinge placement, and (if you elect to build a two-arm tracker) drive-camera contact point placement.. .
