... or check out Pablo Requena on you tube, he has a solera in which is raised the whole surface with cork instead of cutting a dome into the solera. ...
The Cumpliano book has an interesting solera method using a kind to cork rim to create the depression. Quite neat - I have never used it but also a clever way of doing things.

I recently cut up an old leather jacket for workbench use, e.g. vice jaws and the like. I am wondering if (as it is rather good quality thick leather) if that would work instead of cork?
Kind regards,
Simon.

If you get it glued down even and flat it could work but I'd sat far from ideal and the leather is very useful for many other things where it is ideal. You could glue a 4mm thick layer of wood, something like poplar would be nice.

OK, here is the latest. We went to Castorama today; all ready to buy some plywood...and what is the first thing I see when I get to the Bois (wood) section? Yep, 18mm MDF and the first piece I pull out is 1000mm x 610mm! Cost, 18€. As I had to cook dinner when we got home, the best I could do tonight was pencil in the 900mm x 530mm dimensions. Looking forward to Monday morning to start work on the solera.
Kind regards,
Simon.

Stage 1 complete. I have drawn on all I need at the moment and cut out the solera (just some sanding to do to smarten it up), decided to stop for a nice cup of tea.

Slots cut. Now comes the bit I am dreading, dishing! I have made a 10" telescope mirror in the past using homemade lapping tools, but this scares me more.

Nothing to be scared about! I did mine, in MDF, with a card scraper, checking evenness and depth of curve with a straight-edge placed across.
You know about the dangers of MDF dust, so hold your breath for half an hour whilst you are doing the job....

Looks good. What depth did you decide on at the bridge and the neck slant?

I think it works out at a slope of 1.5mm to the nut and a 3mm curve in the centre of solera lower bout using a 25' radius.

I just used the search function at the top and put in "Making a solera". There are too many just to put in a link to one or two. Probably find something on youtube too.

Hi all,
Just about to sand the slope on my solera; from 12th fret position to end of neck. I am using half sandpaper covered piece of wood pivoting from back of the solera with a spacer made while the straight edge resting on a spacer of 1.5mm at the 12th fret and the top end resting directly on the tip of the neck.

My question is should I worry about the 0.5mm thickness of the sandpaper and if so what is the best way to compensate for that 0.5mm please?
Kind regards,
Simon.

If you put sandpaper on both ends of the wood, it cancels out unless I don't understand the plan. see pm
