Jim sorry to be a pain but what are the dimensions of the smaller plinth?, i've got the depth from your other photo.
One thing i've realised i might have to do is to cut a recess out to accommodate the reversing mechanism on my base as i don't know what the clearance will be until i get it.
Your bases look like silky oak?
Hi Philip the smaller plinth is silky oak, the larger plinth is a tropical hardwood from up north.
The dimensions of the small plinth are -
60mm wide
15mm high (this is high enough to for the flywheel to clear the bottom plinth)
105mm long
