Perhaps a way people can learn from my mistakes and successes rather than reinvent the wheel. In this project I had both.
Can’t claim this is my idea. I had a response ages ago wherein someone told of creating removeable gondola weights inside plastic wrap. There may be some magazine article on this too.
I needed to add weight to this set of 10 ore cars I picked up on Ebay (the axles were in horribly rusted shape…had to add new wheel sets to half the cars)
Anyway, thought I would give the glue process a try and use things I had on hand…a lot of left over WS coarse buff rock to use. I needed about 1.5 oz in each car. So I didn’t need to fill them up. Nor did I want to, in case the bottomed out load did not fit back in because of exapansion or something.
So I used sections of carboard roll to create a false bottom. Cut out triangles thinking I needed to create a drop at the end of each pile.
Measured some of the WS rock. It is quite light.
I used a 50-50 mixture of white glue with a little alcohol. The load is quite thick and even thinned glue would not reach down to the bottom. So I first used glue on the first 2/3 of the load which was about level with the sides. Then topped up the load and added more glue.
A little spray from the air duster to drive the glue further down quickly.
Then I set the loads out in the cars to dry. Well, here some problems began. The tops dried quite well, but I discovered the bottoms were completely wet after
