Gravity roller conveyor on 15-series side frames: 1.9 in rollers, 7/16 hex axles, 3 in pitch

How do I build a roller conveyor from T-slot extrusion? · Hardware · basis: Xem Studio design: Ø1.9 in rollers on 7/16 in hex axles (the common gravity-conveyor sizes) between two 1515 side frames, holes at a 3 in pitch on the rail centre line; legs from 1515 set the roller-top height

Exact dimensions. True size, with no printing tolerance added.

Notes

• Roller top = side-frame centre line + 0.95 in. Set leg length so that sits at your bench height.
