We were supposed to lay some concrete founds this morning but with snow on the ground and heavy rain forcast I called it off and spent a few hours playing in the workshop instead
No special kits available but very enjoyable in spite of it being bl**dy cold in there, (better than mixing concrete) 
The streamline is sycamore and has a transluscent effect which the photo doesn't show, other two woods are bamboo (chopping board) and hawthorn from my field hedge.
