Pictures of Jeff's 16" Dobstuff Rocker-Box Upgrade. Jeff lives in Amelia, Ohio. |
here are some images for your blog/website. I remounted the Lightbridge on your custom rocker box today and it fits perfectly. Motion is also effortless. One of the images shows a 2+ pound 2" 40mm Explore Scientific EP and one pound StellarVue Finder scope being held in altitude without effort by the brake you installed (plus 4 lbs. of counterweights at the rear cell). . . .

Jeff placed his telescope onto the bottom plate of the Meade particle-board rocker box for his "wheely". Easy to move! |
Detail of the alt-az "break" and the eyepiece trays Jeff added. Nice job. |

The 10" Ultra "kit" is virtually complete for Dave in San Clemente, California. (This telescope was "partially built" -- so it's a bit more than a kit!!) |
Detail of the "mirror and rocker box" -- the mirror cover is in place. |

Continuing construction of Dave's 10" Ultra Telescope The mirror cell is complete. You can just see the 9-points of contact. (the mirror cell was optimized with Plop) |
The mirror cover now in place. It's held in position by with small bolts/wing-nuts for easy removal -- but stays in place during transport. |

John C., from Andover, Kansas, sent along a couple of pictures and some comments about his 16" Lightbridge rocker-box upgrade. Here's what John has to say"
I had a break in both winds and the spring grass burns in the Flint Hills of Kansas last Saturday morning and got some really good viewing in between the hours of 2 and 5 AM. The evening before I shot several pics. Here are two of them.
The new box works very well and is so much easier to move around since it only weights 25 pounds and has smaller dimensions as well. It is nice to be able to reach the eyepiece when the scope is at zenith since the Dobstuff box is nearly three inches lower. The motions are smooth and quiet. The box is a joy to use!
At first I thought the holes in the sides were a bit odd, but now I really like them. Not only do they make good handles but they let me easily reach inside the box to store lens covers, glasses and other small items when I am viewing without a table. I will need to find a way to add some extra friction for the heaviest of my eyepieces. I have an idea or two for that, but I think I can use something like the device on the original which is nice since it is adjustable. A small felt furniture glide and some creativity with something from a good hardware store should do the trick.
Thanks for your excellent and quick work.
