Steering Column Support Jigs:
Steering Column Support Jigs:
Objective: Produce structure to accurately and rigidly constrain steering column race for tube support welding.
Objective: Produce structure to accurately and rigidly constrain steering column race for tube support welding.
Design
Aluminum T-slot extrusions mounted to optical table (relative to rest of frame)
3D printed supports to cradle upper column and gearbox at exact angle
Full jig in CAD (not shown here)
Manufacturing
Band saw and manual mill to cut and machine extrusion to exact length
verify tolerance with a height gauge (within 5 thou)
Cut holes and L brackets with aluminum stock in same fashion
3D-printed supports with PETG
high density and quality settings to improve accuracy
Assembly
Clamps to constrain gearbox to end of 3D-printed support
Verify fitment, place column race, and tack support tubes
