Timing belts are the greatest thing for many types of equipment. They are a lot quieter then gears and easily allow for errors in placement of various components. I have used them in many projects that required precise timing, not the least of which was my rebuilding of the A3P. -------------------- Ron Walker Orion 11" XLT EQ-G ~ Orion 102mm Mak Burgess 38mm ~ Stratus 21mm and 13mm Dyanscope 4" (1950's vintage) Nikon F 35mm ~ Canon 300D Planetaria: Goto E-5 (Viewlex) ~ Spitz A3P ~ Minolta/Viewlex Series II B

One can also learn about the contractor who built the interesting concrete shell of the McDonnell planetarium (St. Louis). To paraphrase "Fletch": "It's all timing belts these days". -------------------- Charlie Miller Iowa City, IA Director Iowa Space Science Center project www.IowaSpaceScience.org Other Projects: Science education, Spitz A4, Home-built planetarium (6.35 limiting mag); single fisheye digital projection system.

It'd be fun photographing it! (and seeing it work). I wonder if it's still supported "in mid air" with cables? -------------------- Charlie Miller Iowa City, IA Director Iowa Space Science Center project www.IowaSpaceScience.org Other Projects: Science education, Spitz A4, Home-built planetarium (6.35 limiting mag); single fisheye digital projection system.

I would imagine that the eight cables still support and stabilize the projector. -------------------- Ron Walker Orion 11" XLT EQ-G ~ Orion 102mm Mak Burgess 38mm ~ Stratus 21mm and 13mm Dyanscope 4" (1950's vintage) Nikon F 35mm ~ Canon 300D Planetaria: Goto E-5 (Viewlex) ~ Spitz A3P ~ Minolta/Viewlex Series II B
