RUPES BigFoot Backing Plates form part of an innovative system of dual action machines and accessories (collectively termed the RUPES BigFoot Random Orbital Polishing System) that has been designed and engineered from the ground up to produce optimal results in minimal time whilst simultaneously maximising user comfort and safety. All of the components associated with each machine in the BigFoot system are carefully matched in terms of their size and weight, so as to ensure that the balance of the machine is optimised and vibration levels are minimised. This includes not only the machine itself, but also the backing plates and pads. Therefore, in order to get the best possible performance out of each BigFoot machine (and to preserve its one year manufacturer's warranty) it is important to only use it in conjunction with officially designated RUPES accessory products (with regard to backing plate options for the various BigFoot machines, please see the detailed RUPES usage notes provided in the How To Use tab). In reality many people are ignoring the above advice, and have modified their BigFoot machine(s) in some way or another, either by modifying its clutch mechanism (to make it oscillate faster) or fitting it with a different-sized backing plate (because they wish to use different-sized pads with it). While these modifications may appear to work successfully, they are technically in breach of the warranty terms RUPES spell out. Don't say we didn't warn you!
RUPES BigFoot Backing Plates form a major part of the BigFoot Random Orbital Polishing System. All of the BigFoot backing plates are made of moulded polyurethane foam, which is particularly resistant to mechanical stress. Furthermore, they are all engineered to meet a specific weight target, which ensures they work in harmony with the counterbalance in the machine they are intended for. This, combined with the same approach to making the BigFoot polishing pads, ensures that the balance of each machine is optimised and that vibration levels are minimised. The carefully positioned holes in each backing plate create an airflow pathway that dissipates frictional heat and helps to maintain safe working temperatures, even on relatively sensitive substrates such as aluminium and carbon fibre. The material used to form the hook and loop fastening system on all of the BigFoot backing plates is particularly effective, providing solid anchoring and exceptional pad/disc stability while each machine is in use. The use of 150 mm BigFoot Microfibre Pads with the LHR 12E, LHR 15ES and LHR 15 Mark II polishers necessitates the fitting of an alternative backing plate. This is because the 150 mm BigFoot Microfibre Pads are heavier than their foam counterparts (a similar solution was not deemed necessary for the significantly smaller LHR 75E polisher, due to the weight difference between the two types of pads being negligible at the 75 mm size point). The microfibre-specific 125 mm BigFoot Backing Plate (differentiated by its grey/black colour scheme) is lighter and has a repositioned centre of gravity, thus ensuring that the low vibration performance of the LHR 12E, LHR 15ES and LHR 15 Mark II polishers is not compromised when using the 150 mm BigFoot Microfibre Pads.
RUPES usage notes: (i) the 75 mm (Grey/Grey) BigFoot Backing Plate is designed to fit the RUPES LHR 75E Mini BigFoot Polisher, and should be used exclusively with RUPES 75 mm X-Cut Abrasive Discs, RUPES 100 mm BigFoot Microfibre Pads and RUPES 100 mm BigFoot Polishing Pads; (ii) the 125 mm (Grey/Grey) BigFoot Backing Plate is designed to fit the RUPES LHR 12E Duetto BigFoot Polisher, the RUPES LHR 15ES BigFoot Polisher and the RUPES LHR 15 Mark II BigFoot Polisher, and should be used exclusively with RUPES 125 mm X-Cut Abrasive Discs (LHR 12E only, in conjunction with a RUPES 125 mm Soft Interface Pad) and RUPES 150 mm BigFoot Polishing Pads; (iii) the 125 mm (Grey/Black) BigFoot Backing Plate is designed to fit the RUPES LHR 12E Duetto BigFoot Polisher, the RUPES LHR 15ES BigFoot Polisher and the RUPES LHR 15 Mark II BigFoot Polisher, and should be used exclusively with RUPES 150 mm BigFoot Microfibre Pads, and; (iv) the 150 mm (Grey/Grey) BigFoot Backing Plate is designed to fit the RUPES LHR 21ES BigFoot Polisher and the RUPES LHR 21 Mark II BigFoot Polisher, and should be used exclusively with RUPES 180 mm BigFoot Polishing Pads. General usage notes: (i) always switch off your machine at the mains before fitting or removing a backing plate, and; (ii) always ensure that you tighten the backing plate sufficiently, but without over tightening it – a half turn of the Allen key after it first pinches tight is usually sufficient for safe and effective use.
