Dob dolly ideas
« on: December 29, 2017, 04:19:26 AM »
I am planning to move my 12.5" Obsession to my garage and looking for ideas/feedback on dob dollies. I don't have room to use wheelbarrow handles so am thinking of making a dob dolly that the scope can sit on out of 3/4" plywood with 5" semi-soft locking wheelshttp://www.colsoncas...cs/default.aspx
I would like to be able to leave the scope on the dolly permanently and just wheel it out, lock the wheels and observe. Not sure though if just locking the wheels will provide enough stability for using dsc as any movement in the swiveling of the wheels would be a problem. I could add floor lockshttp://www.buycaster...c-d-flpdl-5.htm for added stability. Any advice will be appreciated.

Dave

I think the JP Astrocraft solution might be worth consideration. I haven't seen an example in real lifemyself but I can see how it would work and how clever it is.

I used a hand-truck to move dobs. Just add some padding to it. Worked great.

+1.

Works great. I don't even have padding on mine.

I can roll my scope out from the covered patio and be observing in under two minutes.

Even better, when I am done, I can roll it back in under two minutes.....

Makes my SV110 seem hard to set up by comparison.

A dolly lifted up on a wide wooden block to raise the steering wheels of the ground has worked for me. If there is any wobble, I just shove a wooden shim under the block on the low side. The handle does fold down and so I reversed the brackets so it folds away from instead of into the scope.

I use a dolly for my 11" Dob. Pipe insulation foam on the dolly's struts, from Ace, plus some duct tape worked for me.Dark skies.Jack

I have two dobs and a GEM mounted reflector all on home made dollies of differentdesigns. They are all huge improvements vs. carrying. My largest dob has wheellocks as all the dollies do but I rarely need them as the scope is massive enoughapparently that the wheels don't move when I turn the scope on its AZ axis. The smallerscopes definitely need the wheel locks so YMMV.As a lot of us have discovered, putting wheels on a large scope and storingit at ambient temperature (mine is on an unheated porch off my observation deck)makes it grab-N-go.Dave Y

I have tried the J.P. Astrocraft scheme of attaching a pair of wheels to the rocker box, securing the OTA to the Rocker box and then just using the entire scope as a hand truck. The wheels were very crude but they were very effective, the scope was easy to move. Just make sure the OTA is well secured to to base.

I prefer that to a low dolly or hand truck. With a dolly, to make it truly rock solid stable requires either unloading the scope or some jacking screws. The hand truck has potential for damaging the finish.

If wheel barrow handles are not practical, I'd look carefully at the J.P . Astrocraft Sweet 16 for inspiration.

I use a home-made "movers dolly" and observe with the telescope on it.

I cut a square piece of 3/4" plywood to match the scope's largest base dimension and mounted 5" soft-rubber casters to each corner. I originally tried 3" casters but ride too rough and catch on every crack and twig. Two of the casters are steerable. I then cut holes for the ground board legs and center bolt to set in; this hold the scope in place and prevents its "walking" on the dolly board. I use a piece of clothes-line attached to the leading corners, along with the tube itself, to pull and steer. The casters I used do not have brakes so I sometimes use stick to chock the wheels (but it's real flat around here).

The set-up works well for me. It increases the eyepiece height about 6" but stores in the same space as the scope alone would. I've never taken it off of pavement but my lawn tends to resemble a bog much of the time and, at a dark site, I set-up straight from my truck.

Pinbout,
Back when I was playing in the "Cowboy Action Shooting" sport, everyone had a "gun cart"; a rolling gunrack, generally with an attached box-cum-seat for ammo, drinks and snacks. Some of them became an ends to a means in and of themselves. Google "cowboy gun carts".

In any case, one pattern was based on the frame of a jogging stroller and your idea there reminds me of those.
