[QUOTE="Vipersan, post: 800147, member: 325666"] Sorry Captain 'Super'Jack .. :)...sorry couldn't resist.. Many years of trying to repair broken polythene gears in VCRs led me to one conclusion .. There is No suitable glue to join polythene ...particularly when its under stress .. The only effective way I ever found to do such repairs (as you already hinted at )..was to remove the offending gear ..and find a thin metal sleeve of ferrule to slide over the fractured part of the gear.. Acting as a support sleeve.. This requires finding something suitable and cutting to length ... To fit .. Heat until it expands .. Quickly slide over the damaged plastic bush ...and immediately drop into cold water .. The sleeve contacts ..thus closing the fracture ..and is permanent ...requiring no glues whatsoever.. Hope this helps.. On smaller gears I kept a supply of old telescopic FM aerials to cut small sections ..and make sleeves from .. This looks bigger ..so a suitable sleeve donor will have to be found.. good luck VS [/QUOTE]
