Thanks Luke, getting there slowly between other bits and pieces and life in general!
Have had to resort to sandblasting the wheel which has resulted in the front getting scratched so will have to repolish it but was necessary to get to some parts i couldn't otherwise reach.
The paws are improving slowly thanks, apparently won't ever be right (it's an age things apparently!
) but the worrying bit i had one one of them turns out to be an inflamed vein and gentle exercise is allegedly the answer.
Turned out my original el-cheapo, DIY/home-made blast cabinet was too small for the wheel so i've just invested in a bigger plastic tub from Wilkos to repurpose as a bigger blast cabinet.
Hopefully have more photos later today if it works!
