New radius dish, part I

I got tired of my old dish that I routed out of solid MDF ages ago. So I decided to have a go at this method that I learned at Ukulele Underground. A 3 mm board will be forced down onto circles of small blocks, going from 2 to 6 mm. The distances and heights were worked out in Autocad.

The radius I chose for the dish is 2500 mm.
