My Daughter's Phil and Teds E3 Pushchair has a plastic moulding which holds the sprung brake lever.
This moulding has broken and the brake no longer works. The moulding is a brittle plastic which I think this is a poor design for an important safety item.
The moulding is not available as a spare.
Have the team any ideas for a replacement, perhaps making a new moulding (how would I do this?)
The push chair is out of warranty by the way before the lawyers step in.
I would be tempted to use a bit of metal - mild steel for example.
That would be ideal but would require an NC machine as the mould is a complicated L shape with two holes for tubing as well as a slot for the brake.
Indeed. Or brass if yuo cann get it.
Its surprising what a few hours of elbow grease and files can do by way of turning a solid lump of metal into a usable component.
Another option is cold casting resins and suitable fillers.
A human with a file makes a very good NC machine..
as the mould is a
Sounds dead simple to me.
Use polymorph.
Thanks Peter That sounds ideal. Has anyone used it in a medium strength application?
At up to 50 deg C it is similar to nylon and very tough, it won't crack. Drilling it requires care as the heat from the drill bit melts it - drilling under water is best. Above 100deg C it becomes adhesive and will stick to you (and burn you).
Yes - worked fine.
As Peter says, it's hard to saw or drill as it melts at such a low temperature. Hand tools and working slowly does the trick.
