So I went down to my shop and made sucha bearing for this little essay , unfortunately not all of the pics , that I took , turned out well , I apologize for that , but I'm sure , that the working proccess is still understandable .
Since I do not have a metal lathe in my shop , I have tried to make smaller round metal parts out of round brass dowels simply by chucking them in my drillpress and working on them by filing against the rotating workpiece , which worked out to my satisfaction .
I have made these prop bearings that way , but also inline-spinner bodies , bullet weights for worm rigs and weights for weighted floats are possible to furnish in the same manner .
Only by now I have wood lathe , that has a chuck as well , so I am nowadays doing such work in that one , since it is more powerful and it is also more convinient to work on a horizontally chucked workpiece .
But for this describtion I did it in my drillpress for once more .
Allright , here we go :
First , cut off a piece of that brass dowel , approx. 1" long .
In this case , the dowel is 6mm in diameter .
I can buy these brass rods in local tool marts , but also RC-model shops carry them .
After file the two ends smooth and plane and slightly break the edges .
This is only done for better eyeballing to mark the center hole position with a 90° center punch .
If the indention should be out of center , one can "move" it a bit by setting the punch at about 45° and gently hammer it into proper direction , after make it a bit deeper with the punch .
Mark either side of the workpiece this way .
