Hi Everyone!
First, thanks Burgerman for making this very useful resource!
I use power chairs after a spinal injury nearly 30 years ago and I’ve always tinkered with my chairs. It’s mostly physical changes like custom side rests, headrests etc. I generally find the standard parts to be too bulky. That’s partly because they need them to be adjustable to most users but of course I only need it to fit me.
I do a lot of 3D printing for work and have made some wheelchair parts that way. Have also used aluminium and carbon fibre.
I mostly use Permobil chairs, from the Max 90, through to the Entra, C300, C400 and an F3. I drive with a sip&puff controller, which I don’t think is very common but it works really well for me. I usually buy a used chair on Ebay and either modify it to my needs or use it for parts. My favourite chair for indoor use is still the old Entra, as it’s quite small and nimble. Also using the F3 wich is much smoother outside.
I’ve stuck with Pilot+ chairs for a long time as I like they way the sip&puff tech works on there and I have the P&G programmer for it. Now it’s time I get an Rnet programmer and software though so I can tweak the F3 parameters as well.
I'm in Oxford, UK.
