Replacing the lead screw and nut on a mill.
The new screw 1 x 36 " at 10 tpi. No, I do not mill with a drill chuck, I was counter boring a screw hole. After examining the lead screw and nut on my mill it became apparent that due to the wear on the screw that I would be better off starting with a new screw. I ordered a three foot piece of 10 tpi x 1.000" acme threaded rod.

Rod Mill Grinding
Since the mill was operated in an open-end configuration, the discharge end was completely open, except for a wire grid to prevent balls or rods from falling out of the mill. Hollow Lucite rods of density 1.25 g/cm³ and 1.9 cm diameter were used to simulate the grinding media without any appreciable grinding action.
Making Steel Coupling Rods
Valve gear was made from steel and no matter how hard you try nickel silver is not the same colour as steel. My second big bugbear is "profile milled rods" – milling the fluting with an end mill just looks completely wrong. The shape at the end of the fluting should flare out not end in a semi-circular hard stop.

Reducing the diameter of steel rod without a lathe?
It's for a missing fence rod on a Stanley #78 rebate plane. I have the fence itself, which appears to need a ~7.3mm rod, but the end of the rod screws into the body of the plane, which appears to be M6. It may be that the original rod is 9/32" (7.14mm) but the thread into the body is definitely not 1/4" UNC (an M6 bolt fits reasonably well).

General | Milling machine drawbar
When I got my Webb Mill, it had a Snap Changer on it with a special drawbar but there were no collets with it. Since the Snap Change collets are someting like $100 apiece, I sold the unit and made a new drawbar out of a piece of 7/16" 4130 rod that I had in my stock bin. I used a piece of stainless 3/4 hex for a head and welded that on.
