The first is the West System. This is an epoxy resin based system for the building and repairing of wood and glass fibre products and is used extensively in the wooden boat building industry and for repairs to wooden structures and architecture in old / listed buildings. Mixed with a slow acting hardener it can be used to reinforce rotten timber and may be useful for repairing machine cases, especially where carved designs would be lost by replacing the rotten timber with new.
The epoxy resin can be mixed so as to soak into / through rotten timber and when it hardens it will form a resin reinforcement within the wood; very useful, perhaps, for entombing woodworm.
West Systems also supply a range of fillers that can be added to build up lost sections.
There is a lot of information and scenarios on the West Systems web site.
This link shows how the product could be used for repairs to wooden machine cases;

The second is Entex Stock Springs, who supply a HUGE range of springs in lengths and with hooked ends. Our Allwin machines mostly use ¼” and 5/16” diameter springs for the hammer action and these are available as Tension Lengths, 2ft long, in five wire thickness.

I have no connection with either of these companies other than being a satisfied user.
