I'm wanting to build a double top (cedar/nomex/cedar) and I'm unsure exactly what to buy and where to source the nomex and the glue in the UK. I'm also unsure about the best thicknesses to work towards. From the reading I've done so far, I think that 0.6mm cedar / 2mm nomex / 0.6mm cedar should be about right. I haven't yet found this info in one place though - any thoughts?
I have found that http://www.easycomposites.co.uk/#!/core ... -honeycomb
has 2 types: 3.2mm cells and 4.8mm cells.
The 3.2mm cells material is lighter and it's available in 2mm or 3mm thickness. The 4.8mm cells sheets come in a minimum thickness of 5mm. Can it be sanded down? (I've never worked with nomex before).
I'm thinking about getting the 3.2mm cells sheet at 2mm, is that too thick for the nomex sandwich? Are the cells too small?
I have been watching the O'Brien Guitars video on building a dhouble top where all the dimensions are given, but for a steel string guitar, not classical. https://www.youtube.com/watch?v=uIq-ExdmG5I
In the second part of this 2-part video, he explains that they used System Three T-88 thixotropic resin. This seems to be cheap and available in the USA but I'm having trouble finding it in the UK. Does anyone know of an alternative that has similar properties?
I know this is a lot of questions in one post. The O'Brien videos I mentioned above are full of great advice for the process - these questions are to fill the gaps I need so I can get started. I'll share my experience on the forum once I'm done so as to benefit others.
