Machining the backplate
The real work to getting the chuck installed was really machining the backplate. I first bored out the lip of the hub so that it would fit onto the spindle head properly. Then I faced off almost a third of an inch from the hub to get it to engage the spindle threads. Then I put the backplate on "frontwise" - the way it will be used, and proceeded to face off the front and bring the registration boss to the correct dimension to fit the inside of the chuck. This registration boss had to be machined precisely to ensure the chuck would always mount true and run true to the backplate and hence the spindle. All this machining took most of a day and produced a lot of iron shavings - well really more like sand! What a mess!

| TADA! The new chuck is installed! |

| View from the side. This chuck is screwed to the backplate form the front. |

| This stuff is everywhere! |
 |
| I tried to keep it contained, but it still got everywhere! |
 |
| This is the little that I was able to collect. The rest got vacuumed up or wiped up when I cleaned later. |
