Hi Jack,
I thought I would post up some pics of my SC KXD-2 blade holder. Finally cool enough to walk over to the shed today! There has been a very real risk of heat stroke just walking outside to fetch the mail lately!
Some dimensions first.
Distance between centres of outside holes: 300mm
Distance between centre of central hole and centres of outside holes (straight): 150mm
Distance from centres of outside holes to rim: 21mm
Central hole diameter: 12mm
Outside holes
total diameter: approx. 21mm
Polythene "cushion" thickness: aprox. 2mm (Was this cushion made of brass originally?)
Bushing outside diameter: 15mm (note bushings are also "wrapped" perhaps due to wear?)
Bushing inside diameter: 10mm
Bushing length: 22mm
Blade holes each braced on top side of disc with 20mm X 30mm X 20mm (X 6mm high) brace.
Blade holes raised approx. 3mm from plate surface on bottom side.
Blade holes raised approx. 13mm from plate surface on top side.
Blade plate has a 12-13mm flange angled up approx. 45 degrees on outer rim.
Here are pictures of the bottom of the blade holder ("plate"):

And here's the top side of the blade holder ("plate"):
P.S. I guess there is a very real possibility that my blade holder is not original?
