‘MarWick’ Brush Insulating Sleeve – For easy DCC conversion of early Graham Farish locomotives. A joint venture by Mark’s Trains and Wickness Models.
A sleeve designed and manufactured to aid the conversion of early Graham Farish ‘Poole’ built locomotives to DCC. With no chassis drilling required, no mess, and a quick and easy installation.
Fitting instructions supplied and can also be downloaded here.
The ‘MarWick’ Brush Iimages/bis-instructions.pdfnsulating Sleeve has been designed and manufactured to the exact measurements of the original Graham Farish brass brush sleeve, used to aid the conduction of electricity between the chassis and brush. The ‘MarWick’ Brush Insulating Sleeve is manufactured from a Polyoxymethylene copolymer (POM-C) also known as Acetal. It is an engineering thermoplastic used in precision parts requiring high stiffness, low friction, and excellent dimensional stability. POM is characterized by its high strength, hardness and rigidity. It has a melting point of 175°C.
The ‘MarWick’ Brush Insulating Sleeve is designed as a direct replacement to insulate the brush and spring from the chassis to allow easy and simple conversion to DCC, and by insulating the retaining clip with the Kynar heat-shrink provided, this provides the complete isolation from the chassis and track pick-up required for a successful DCC conversion to take place.
This is a 10 pack consisting of 10 ‘MarWick’ Brush Insulating Sleeve and 10 x 3 cm section of Kynar heat shrink tubing plus fitting instructions
