Rebuilding a chassis.

Hallo again.

I have been looking at the 0-6-0 goods engine which would not traverse my pointwork.

It was suggested it might be a back to back issue, so that was indeed my starting point.

Unfortunately, the existing chassis couldn't be narrowed to allow the b2b's to be lessened a tad ( I was aiming for around 0.2mm), so I was forced to remake it from scratch.

I have just taken delivery of a strip of 0.3 phosphor-bronze, so I thought I would try working with that.

Here is a photo of the finished chassis, which is an exact facsimile, in order to fit the prepared Union Mills body.

It went together a treat, and rolls freely in both directions.

The P-B being slightly thinner, I could reduce the back to back slightly when I reassembled things, yet the subframe would still lock in as before and fix with the screw.

The good news is that it passes through the turnouts now.

Unfortunately the engine refused to run due at first due to a short somewhere! However this was traced fairly quickly to one of the pcb spacer cuts not being quite through at one end; and the cheesehead shortcutting across a different part.

I was quite impressed with phosphor-bronze, and may use it again for the 1F's frames.

Regards,

Chris
