Tripod wheels
« on: December 28, 2017, 10:00:07 AM »
Is this a good idea? I have a Losmandy FHD tripod and I'm thinking of putting caster wheels on it, so I can roll it out the garage fully loaded and be ready to go in a flash.

Any recommendations for a good set of wheels? I don't want the full spreader type set up, just individual wheels at the bottom of each tripod leg.

Here they are fitted to my 2 inch tripod.. they just slide up onto the bottom legs and then nip up the grub screws.
cheers

Man I sure could use some of these! Methinks it may be time to go have a talk with a local metal fabricator.

Be very careful Wheels should be fairly large (to go over cracks and bumps) and they should be fairly hard (so your rig doesn't bounce up and down when touched). Losmandy made them at one time but quit do to problems (to many crashes). When moving the rig you need to have the legs set to the maximum distance apart and do not push the rig on soft surfaces, flat surfaces only. There is no way to level such a rig.

Hi Allan - I am using the scope roller 5" for a older Losmandy GM8. I find the larger wheels a must for the conditions here in Ontario Canada. My set up rolls out of the garage and the larger wheels help in winter conditions over ice andtrace amounts of snow. I roll about 35' on a paved driveway then up a ramp. Reasonable price and so far durable with no mishaps. I do go slowly though. Once I'm aligned I use the locks. As Bill mentioned the tripod should be stable with some way to keep the legs from collapsing inwards. I have spreader and tray below that helps.

I believe the vendor's name is Clayton and the site is Scoperoller in the US. Worth a look at anyway.
Good luck with your search

David

They might be ok for visual use but i would never image off wheels.

Hi David,
you are correct that you need a spreader and tray to lock up the legs to be able to use castors with any success. My photo above shows the spreaders I built but does not show the alloy tray I also built for them but when fitted the way I have designed it, it locks the tripod up so that no movement in or out of the legs is possible and it also stops any twisting motion that can be generated when the mount is slewing around.

To Bill, yes they prevent levelling adjustment as normal but I have a levelling adjustment system on my mount to take care of that.

To Glend , I agree it's really only for visual. As I mentioned the bearings in the carriage must be top quality to prevent wobble. Also I use hard rubber wheels with bearings inserted in those as well.
cheers
Graham

I used to use 3 of these:

to move my fully loaded EQ-6 from the patio to under the eave.

You lift one leg at a time and put the dolly under it, and when all 3 legs are supported just start pushing. Remove the dollys one leg at a time.

Just google "tri-dolly" and you'll find lots of variants:

Graham, thanks for the photos. I found those castors today. Next I need to get those tubes made up. The Losmandy FHD has hollow legs, so I will make something that slides up inside them.

Good idea Duncan, but I will stick with the individual castors for now and see how they go.

Allan your welcome to the photos. I'm sure being a fellow astronomer from down under you will do just fine with your build.
How about a photo when you are finished.
cheers
Graham

I own a set of ScopeRollers, solid product I can vouch for.

Man I sure could use some of these! Methinks it may be time to go have a talk with a local metal fabricator.

And done! I got hooked up with a fabricator who is just 4 miles down the road with a shop full of metal fabricating goodness. We made 6 of these and I am into it for just under $100. We swapped favors for his labor, he supplied the shop and I sold a camper for him. I wanted to use a nylon screw to avoid scarring the tripod leg, unfortunately that didn't give me the required grip. So I added some heavy gasket material with double stick tape, and all is good. Now if the skies would cooperate!

Hi, I'm glad my design could be of some help to you. Hope they perform as you would like. By the way the grub screws in my system go into the holes that were already in the bottom of the legs. These are what the bottom leg caps were screwed into so no marring will happen from what I have done.

cheers
