Innertubes are ace for 'stuff'.
Remember, us fix it folk are in the minority these days. Its often cheaper for someone to buy new than get a trades person in to fix it. Many folk aren't interested.
The dryer we have is a small one that fits in our porch. They aren't expensive but aren't common due to size. Must say google etc has really helped locate parts. Cost about £8 to fix the bearing on the dryers drum. Did involve pulling the thing to bits, literally, but it was all there on google.
My colleague has impressed me. She lives at her mums house with her two sisters. They have replumbed a bathroom and tiled it, as well as other refurbs and done the whole house, all by watching you tube videos. No previous DIY experience.
It can be done.
They have done such a good job (I've seen the pictures) their mum finds another room for them to do. I think they have just one room left to redecorate.
