Help on stickion pad disk needed
Anyone know where I can buy 1/16" thick (telfon?) friction material? I recently bought an Alpine Astronomical NexStar Dovetail Mounting Bracket - http://www.alpineastro.com/mounting_accessories/mounting_accessories.htm#Nex... There appears to be a part missing from the product and consequently it does not function properly when installed. As shown in the folllowing photo, on the bottom of the lower mounting disk, I believe there should be a small circular friction or "stickion" disk. http://members.csolutions.net/fisherka/astronote/photos/SitckionDisk.JPG The photo shows the stock NexStar mount (on the right) and the Alpine aftermarket dovetail replacement (on the left). The red friction disk appears on the NexStar mount. When the Alpine replacement is installed, the mounting disk wobbles and rocks in place and turns freely without connecting to the clock drive disk. The stock part firmly grips the clock drive disk and does not move or wobble. I believe there is a small adhesive friction disk (made of Teflon?) that attaches to the bottom of the unit that was not found in the package. While I am working with the seller to resolve the problem, I was wondering if the disk friction pad was a common material used in ATM and if I could easily buy a 6 inch square? Thanks - Kurt
It's commonly available. Try either Regional Supply (though they won't cut you a small piece; hopefully there's a scrap in their scrap bin) or give me until Monday to check my own scrap box. If I have it, it's yours. What's the minimum size that will work? On Sat, May 30, 2009 at 6:08 PM, Canopus56 <canopus56@yahoo.com> wrote:

If Chuck can't help, try Delvies Plastics in SLC at: http://www.delviesplastics.com/. It's been awhile since I was there last but they used to have numerous scrap bins to purchase lexan, Plexiglas, Teflon, etc. real cheap.
