8/12/17 - Pansy

Some smokebox door hinge blocks were made to replace the originals that were not right as you see in the pic.

Beginning with a short brass hex bar so as to fit in my rotary table chuck the 5BA thread was cut first on the ends of the bar. Then the square was milled to 3/16" across the flats on both ends of the bar in the rotary table chuck.

Then the hinge blocks were parted off in the lathe. A 5BA hole was tapped in one end of the hex bar and used to hold the hinge blocks by their threads and face off the ends to length.

The hinge blocks were set up in the mill to find and drill the correct position for the 3/32" hole.

Finally some rollers were made from 3/16" brass and using the door pin it made a good guide to file the small radius to shape.

Happy steaming!
