A Messy Business

This is what a workbench looks like when you're busy resin casting.

That's a new batch of DZ wagons in preparation in the picture above.

I'm about 25% of the way through after a couple of days work.

The most important tool you can see in the picture is the humble cocktail stick.

This is what you use for chasing out as many air bubbles as you can before a slice of Perspex is laid over the top to get a flat back to the casting.

The trickiest parts of these kits are the lumps and bumps on the bogies and the door castings which go on the inside of the wagon.

There is a fine rim, about no more than 0.5mm thick around the outside of the casting which is a magnet for minuscule bubbles.

So far with this batch of DZ's I've had a success rate of around 95% which I'm pretty pleased with.
