Want to tap into the knowledge base on here. Building an 400mm (16") F4.5 newt / dob with a Hubble Optics sandwich mirror and I'm looking for suitable mirror cell designs and also trying to get my head around Wiffle Tree and sling supports.
Have looked at many designs online, Mel Bartels etc and most of the info seems a bit vague to me (or maybe I'm the vague one) and most of the images I've seen so far are not detailed enough for me.
It will be an 18 point floating cell, that part is relatively straight forward to construct, it's the edge support that I need to get my head around.
Thanks in advance for any design tips or insights that will help.

Cheers
Jeff
