Hi

Thanks Chris  :ThumbsUp:

Watching you as well  :popcorn: :popcorn: :popcorn:

The front and rear beams are made of 1/8" steel. I have read in a couple of other loco builds that 1/8" is not really strong/rigid enough for a loco of this size and power especially on the rear drag beam. I toyed with the idea of making another from 1/8" steel to double the thickness but searching through my stock I found a bit of 5mm thick steel so made a new one. It took only 15 minutes to make using the old one as a template



The brass angles that support the cab floor and rear end of the running boards are cut, drilled and tapped M3.



Once fitted and bolted in the frame is noticably stiffer







Cheers

Rich

Hi

PS

As the front and rear beams are identical I have decided to fit the now spare rear beam to the front, doubling the thickness there.

cheers

Enjoying your build, Rich.  Love the red bumpers!  And I'll bet the additional thickness on the front and rear beams will add a lot of rigidity to the frame.

I always have to wait till the weekends to read your thread. Well, its not weekends so much as wait till I'm reading from home!  Your pictures won't show up for me at work.  For some reason, the place you host your photos is blocked by the firewall at work.  But I see them fine at home.  :-\

Great progress Rich,  :ThumbsUp:

Hi

Thanks Per  :ThumbsUp:

While waiting for the preverbial paint to dry I busied myself with a little work on the axle boxes.

First job was to make 4 plates from stainless steel that fit across the spring studs



Followed by drilling the top half firstly 3/16" then 1mm to form oil cups



And finally with a 5/16" end mill form a recess in the bottom half for a felt pad



Cheers

Rich

The paint makes it really start to look like a locomotive, doesn't it?

I'm getting ready for that step myself and I'm worrying about it. I'll say you have done a fine job of it!

Hi

Thanks Kim  :ThumbsUp:

I am a fan of Hammerite, both the hammer finish and the smooth. It needs a good week or so to really harden off but once hardened it gives a really hard wearing finish. The aerosols are good for getting a decent finish.
