Scavenger! Build Part 5 Centering Rings

Because you traced around the outside of the mainframe tube, you can cut a little inside your pencil line.
It shouldn't be too hard if your scissors are sharp. If not, use a new knife blade.





All four rings were set over the BT-50H tube and sanded round and to size.
Go back and forth between sanding and checking the fit in your mainframe tube.





If you take your time, you can get a very accurate fit of homemade centering rings without using plywood on a lathe.
