homemade "scopebuggy" pics?
Posted 29 June 2009 - 06:46 AM
I really need something with larger tires than what I see with commercial units. I have a gravel driveway, and often have to move across the yard. Small wheels would not work well.
So, I may build my own. Anyone have pics of theirs they can post? I'd love to see ideas.
One thought ... just have a wood beam across two tripod legs (under the feet) with two tires attached. I can then tilt the mount/tripod back and wheel it around. The third tripod leg sits directly on the ground.

Larger tires than on the Scopebuggy? They are already something like 10" in diameter and wide with a heavy tread, larger than that and I think you're into much heavier ATV or small car wheels. I know the standard JMI wheelies use small hard wheels which would have a difficult time on a gravel driveway (JMI does have an option for the larger wheels) but the Scopebuggies wheels are considered large and soft. If you really need more than the Scopebuggies wheels then you are into some serious "off roading" ... lol.
There isn't a lot of ground clearance at the front wheel with a Scopebuggy so abrupt changes (sidewalk edges, potholes, etc.) would be a problem but I have no problem taking a Scopebuggy over what is considered a rough driveway or lawn. Stones up to about 2" are not a problem.
I've seen a few homemade configurations pictured here on CN, including a few really creative dolly type setups for alt az mounted scopes. I like the idea of two wheels and lifting the third leg for shorter runs with only the mount. I already do something like that (lift the front wheel off the ground) when I'm going over edges and such with my Scopebuggy.

Yes, I will need some type of pneumatic tires to get across rough gravel, stones, and driveway edging, etc.
Curious .... how is it it, vibrationwise, viewing through a scope when it's resting on those pneumatic tires? Do you have to take the tripod off the buggy?

Viewing with everything resting on the tires is not a problem. I haven't had any vibration or goto realignment issues. I have one level spot where I don't need the levelers and I've accidently kicked the tires a few times while observing. The scopebuggy w/G-11 doesn't move.

It will prob. be faster if I save up a few months and just buy one.
Many thanks all.

I prefer all 3 wheels pivot. My scopes are stored in my basement shop, which has only a 27" wide doorway, so I need the space between tripod legs to worm my way around the doorjamb.
I have my 8" f/6 Springfield on one of these, an EM-10 on another (that holds either a C-8 or a 6" f/10 Newt, though the 6" has to be moved separate from the mount), and a Super Polaris on a Quickset Hercules tripod (pictured here).
This dolly was made with some 1x4's I had laying around. Subsequent dollies I use 2x4's arranged in a "T", like the first link above.
But I prefer all three wheels pivot for maneuverability. I also prefer to move them by pushing on the legs about midway up and/or putting my foot on the dolly to help the scope over bumps and cracks in our brick patio between my shop and my observing site on the grass. That way I have a firm grip on it if it ever wants to get tippy (or is that tipsy?)
All my dollies have different wheels, depending on what I had laying around at the time. The one pictured here has small wheels, but it does okay. The one that works best has 4" narrow wheels from Harbor Freight. These go right across the lawn and bricks without a care. I would think 6" wheels would do fine on most surfaces, possibly even gravel.
I don't like the way the scope buggy is used. I would be very nervous with me at the end of that long handle and the scope at the other, on the dolly. Back before affordable laptops for field use, I used to move my desktop computer around on an old dresser that I put wheels under, and a handle on the end. Once, a wheel caught in a rut when I was moving it around to the other side of the house (for morning planets) and it was like watching a train wreck in slow motion as the computer gently toppled off the back of the dresser on the side away from me. It still worked after that, but that cracked and skewed case always looked rather sad to me.

When observing from my driveway (the east side of the house), I simply put 2 of the wheels in a seam between concrete slabs and I'm good to go. If I set up in the same place, and roll into the crack from the same direction, I'm automatically polar aligned. But most of my mounts have good polar alignment scopes anyway, so getting aligned only takes a couple minutes each time.

So, I just ran a wood screw through each.
On my other ones, the tripod tips fit into holes in the 2x4, and the Springfield is sitting on a "tray" (first one I built has a floor for putting the drive corrector and stuff on. Gravity is hold those scopes down. When I push them around, I have a firm grip on the tripod, so they haven't fallen off (yet).
