#636 Q&A with a Master Builder: Questions for Ralf Langer

Today is the return of the Master Builder Q&A, where you get the chance to ask some of the community's best builders your questions!

This time round it's Ralf Langer answering your questions; please ask them in the comments below, and this could be anything from his favourite piece to advice on a specific part of the building process. Please just one question each, so Ralf can answer as many as possible!

Here is Ralf's Flickr so that you can follow him if you're not already doing so: https://www.flickr.com/photos/154489981@N04

Ralf will be answering them next week, so look at for the post next Saturday; because it's bound to be a good one!
