The plates are to size. They are made up of 3/16 " sheet pilling for seawalls. wasn't wide enough so had to have them welded up to size. Keeps getting bigger.

The grate is finished. This is how I set up to make all the parts the same size and the holes in the proper places.

A little time out from life things to repair my metal saw. The nut that moves the vice jaw broke at the threads. My first try to weld cast iron. Just a little machinating then ready to start cutting out the wheels.

Ed, sorry about the little vise mishap, but you seem to have that sorted out. Happy to see you back on this project also. The grate, couplers, and journal boxes look great!!

How my gear blanks were made before my lesson. After all this is a hobby and I'm in it to learn. Pic 1 turning the gear blanks. Pic 2 repairing the blanks.I made to the wrong size was able to salvage all blanks. pic 3 the material I used all cast iron. No pic of distorting the blanks when my set up to cut the teeth failed.
