Actually did this on Saturday but completely forgot about it until I handed it over yesterday. However, I just looked and I forgot to take a final pic with the shaft insitu. Doesn't matter, as all I had to do to the shaft was polish it.
This is off a wet stone grinder that my neighbour has. It has started to wobble to the point that he can no longer hone blades properly. It is of Chinese origin and had nylon bushes which have worn out. So, I set about making some bronze replacements.
After cutting a section of stock to length, I faced both ends and drilled a hole through the centre and bored it out to 10 though under final dimension. I then turned up an arbour to hold the stock and turned the OD of the flanges. I plunged a cut for the eventual parting line and then either side of the flanges. This way, when I parted them, I could easily chuck them up and face the flanges to the final dimensions.
I made them a press fit into the housing and then used an adjustable reamer with a pilot and extension to finish the ID to size.
Some pics:
On the arbour (angle makes them look different lengths but they are the same):
Parted and faced, and next to the old ones:
Pressed into the housing and ready for reaming:
