To those using the Tekno mount...

[teknorc]

pb4ugo,

I'm not sure we received an email from you. Did you send it to info@teknorc.com? I don't think we've received any packages from you for us to look at a possible defect. I'm still thinking that Neu has changed their spec and it may not be compatible with the 40mm mount. You can try the 42mm mount, but be sure to put a little support inside to take up the slack (tape, velcro, something firm that won't mark the surface)
