Thank you Chris for having sandblasting the all welded trailer frame for my A!
Ready for final assembly now I'm eager to do the job and take some photos.

The equalizers, springs and hangers will be inserted through the generous openings from the top. The rocker seats will be fixed by 2 bolts each
Tests were made before, of course!

Hello friends,
Now the trailer is ready to run (and for the paint shop!).
Some photos are demonstrating the result. Total weight is some 30 pounds. The axles are able to lift/drop +/- 8 mm by means of the equilazers. The rockers will move up to +/- 30 mm left/right while lifting 4 mm.
Now when the job is done, most of the thrill is gone, too. But that's as things are going, for the making is most important (to me). Chris, you will be successful, too, believe me - just a lot of work!

Hello friends of the N&W steam,
Time to post some more photos of the brake arrangements which are identical for both the front and back engine. There were two brake cylinders for each of the engines. This gave the opportunity to use both air and steam for braking. Cylinders are made identical except two slight modifications:
The air cylinders use o-rings as (tight!) piston rings where the steam cylinders are equipped with a pair of small piston rings made of stainless steel. There is an additional small bore for release of water and condensing steam. Each cylinder is working on just two (of three) pairs of driving wheels.
Thus you get a two circuit -fail safe- brake arrangement!

Hello friends,
Having finished the front engine now, it could be moved back to it's right position.
The locomotive as shown weighs in almost 600 pounds - without water and some parts still missing.
As next step I will continue with the same procedure to the back engine including the trailer. The optimal connection of the equalizing systems ob both trailer and back drivers may become a little tricky, yet.

Hello builders,
Here are some more photos of making a detail, which might be of interest to others.
For some of the bolts may not be inserted into the cylinder flanges as intended due to hidden steam chanels and other obstacles, one can set them into the covers as blind srews.
Two missing bolts placed in opposite positions should be used to remove a sticking cylinder cover anyway! Using srews to lift that cover is working a lot better than a sharp tool or hammer without damage.
Making those blind srews from raw thread material seems to be easier and more precise than cutting them from hexgonal raw material.

Fixing the visible nut as fast as possible. Then the front of the bolt should be finished.
Cut off the part as final step

Hello NP317,
Thank you for your kind recognition! Regarding the working hours: Not too a hard time yet but 3 to 4 hours per day, 6 days per week. My target is to achieve the first run under full steam next spring at a US-meeting. Thus time to relax will be later then ...
