Safety first - clamp it!

Temporary or exhibition layouts have one huge advantage over those firmly screwed to a wall - you can flip them on their backs for access when wiring up.

Of course, the model needs to be firmly set up or you'll find it falling towards you and bashing your bonce. Worse, it could fall back and bend the backscene if fitted, or even worse, flatten the scenery.

My layout building worktop has a lip around the edge and so when working on a model earlier this week, I was able to use a onking great clamp to fix it in place.

Soldering, drilling and poking then took place with impunity, and an unbashed bonce.
