I have a lot of slimline kits bought in bulk to practice, they are lovely but I think I would prefer a thicker central metal band for better proportions, (more like the ‘slimlines’ sold by Axminster… is there anywhere I could buy thicker rings and an appropriate bush to go with them - I could buy the axminster bushes, but I don‘t think they will sell the rings separately… (ideally in chrome & gold)
