Hey Jim - very nice design and I noticed that you're also from the Lone Star state. What is it that gives us Texas boys that flair for elegant design and cutting edge vision for manufacturing? I dunno - just blessed I guess. As you can see, I've raised the construction bar a bit so don't take offense at this new entry in the Bahtinov mask design contest. Introducing the “South Texas Chinet Focus Mask”. That's right folks, that cellulose fixture at all Fourth of July horse shoe throwin', washer pitchin', dominoe shufflin', barbeque eatin', Shiner Bock drinkin' family tradition get-togethers! The Chinet paper (actually cardboard 'cause nothin’s too good for the family) picnic plate. Ok, I know you're dyin' for the details so here we go. Downloaded Inkscape and used Adam's mask file (thanks Adam!). Printed it out and Scotch taped it to the aforementioned construction material. I then used the sharpest skinnin' knife I had and cut out (actually chopped out) the mask using Adam's template.
As you can see it is a quick and dirty prototype so I’m really pushing the limit on tolerances required to achieve successful focus. I’ll be reporting back on my "first light" results as we are expecting some pretty good local weather this weekend. Seriously though, many thanks to Pavel for the idea, Dennis for the news and Adam for the scalable vector drawing. This has really been a thoughtful thread and I’ve learned a lot from you guys so “thanks” to you as well.
Ron
