Hello !
I come back to the front and rear handrails problem I faced trying to insert them in place on my two old Katos C44-9Ws.
Thank's again Kusojiji for your advice and explanations on how "rounding up" the square posts ends with a pair of pliers.
As you said, it is a very delicate job, and it didn't work for me. I certainly previously played too much with them trying to find a way,
using superglue, and so on, I just made things worse.
So I decided to superglue (again) small pieces of brass rods I cut with a mini disc. I first cut off the two bottom plastic pins on
the two center posts and glued the brass pieces on the inside faces of the said posts. I left the plastic pins on the two exterior posts,
just "pointed" them with a cutter.
I used a tiny drill to make sure the holes were clean and open to accept the brass rods, and it fitted perfectly. I added tiny drops of
glue to secure my work. Later on, I then inserted the two exterior posts easily. A touch of yellow paint rounded up the job. So far I did that
only for the nose handrails of both locos.
Now, the "look". Eventhough the bottom of the posts is obviously thicker, it doesn't look that bad from normal viewing distance, and I will
live with it.
