[COLOR="Purple"]Slowly, way too slowly, working on my latest ATM masterpiece, an 18.75" cellular mirrored truss dob. I was drawn to the cellular mirror for quick cool down and light weight. The mirror box has come together nicely and is fairly light, even before I do some cutouts. I found a good deal on a 26" pair of nice aluminum alt bearings. I knew they weren't exactly super light but these puppies weigh about 10 pounds EACH! That's another 20 pounds on a mirror box I'm trying to keep manangable by one person, me. Sooooo...I'm drawn to the composite alt bearings offered by Star Splitter. 24" bearings weigh 3 pounds each! 6 pounds vs 20 pounds saves me 14 pounds on the mirror box. The composite bearings are a little pricey but not outrageous, in my opinion. I'm going to order a pair with some Christmas $ I have coming. Anyone here have any experience with the composite bearings? Guess I'll spruce up the aluminum bearings and list them for sale on Astromart.
