At Lammo Ltd we love the Jimmy Jib system. There is a reason that it is the most popular lightweight jib on the planet. That said like most things they can be improved....
With that improvement in mind we use our expert knowledge of the system to refurbish jibs which we then sell on. We believe that our jibs, once refurbished operate smoother & are harder wearing than a new jib straight out of the box.
The refurbishment process includes:
New Fulcrum Pan Bearing: From manufacture the Jimmy Jibs pan bearing rotates directly onto the aluminium fulcrum. This is a design flaw (possibly to do with economics) which very quickly damages the aluminium by creating a 'worn' circular groove. This also ends up with minute aluminium splinters which cause a 'lumpy' feel when panning the arm. This wear can also cause the fulcrum to rock side to side slightly. Once refurbished by our engineers the pan bearing runs sandwiched between two hardened steel discs instead of straight onto the aluminium fulcrum. This creates a non-damaging environment where the bearings run ultra smoothly.
New Tilt Bearings: Similar to the above the hardened steel tilt bearings at both the fulcrum & the head section are mounted directly onto a solid aluminium 'rod'. In the same manner as the pan bearing issues described above the aluminium wears & splinters foul the bearings making the jib feel 'lumpy'. Our solution is to to machine the aluminium rod & fit a hardened steel sleeve at either end so the bearings never contact the alloy again.
New Head Bearings: When the Jimmy Jib comes from Stanton the head uses a nylon bush for its pan bearing
