I finished up the journal box bearings this morning. Also was able to get the shaft made for the front end along with the front wheels. Next part will be the spring shoes. I should have some time to press the wheels onto the axle in the next day or so. Getting there.

I tend to leave wheels off of axles until I am sure everything fits....

it is not always safe to assume that drawings are totally correct (even those that have been around as long as Chloe)...
Too many things going on to bother listing them.

Thanks for the tip. I'll wait until the main chassis is ready to get some wheels before I put any wheels on axles.

Got a little work done on the frame today. I set up both frames on top of each other and lined everything up. I drilled and tapped three holes in the extra half loop on the bottom of the journal box area. I also drilled and reamed holes for 1/4 inch dowel pins. That should keep everything all lined up until the frames are finished. I also milled the top edge of the frames just to be sure they are all the same height. I had added .010" on the top face and the the journal box faces before I cut them out on the waterjet.

Haven't updated in awhile. I got some more work done on the frame pieces. I finished up the brake cylinders with tops and bottoms as well. I think after looking at the up close pictures I may spend a little more time on filing the cast surfaces of the cylinders.


I did start on the main steam cylinder yesterday. I got one side flat and then put it on the surface grinder to make the other side flat. Then flipped it over and ground the first side flat and parallel with the first side. I still have some material to remove from one side to get it to thickness and keep the molded in steam passageways centralized. Still enjoying the build.
