Lensplate and back dimension, a quickie

[Soeren]

Despite my ten thumps Im determined to start building a 13X18cm camera.
For starters I need two dimensions. Lensplate and rotating back.
I figure 16X16cm or 160X160mm would do for a lensplate, or should it be bigger/smaller? The rotating back would be around 220X220mm, or? I think the Ebony 57 outer dimensions is somthing like 230X260 (including knobs)
Kind regards Søren

Lensboard? IMHO either go Linhof 96x98mm or Sinar 140x140x. Both have a fair number of third party boards out there for very little.

Ok Thanks Nick. How thick are they?
Kind Regards

Off the top of my head I don't know. If nobody does later I could measure.

I just made a lens board for a old Graphic View camera, and dimensions in inches, 4 x 4 x .25 " with a .125 " step, I used to pieces of 1/8 plywood. I guess you would use 3mm plywood for a total thickness of 6mm
