A big thanks to Carl on the ATM forum for this, I pretty much copied his plan. I have recently completed adding these homemade wheelbarrow handles to my 14 inch Skywatcher Dobsonian.
I really love observing with this scope, always at home in my backyard where it is nice and dark. Previously however I found moving the base particularly awkward as its huge and heavy, and time consuming to disassemble - move - re-assemble. Therefore it didn't get used as often as it probably should have - it left open too much opportunity for excuses!
I was thinking of re-designing and rebuilding the base out of plywood but decided to try this first.
I removed the small vertical brace pieces and attached the 45mm x 45mm ( approx 1.6 inch square ) handles. This has had no effect on stability or function of the base ( so far at least ) that I can detect.
The handles are 1.5 metres in length with 10 inch pneumatic wheels with a 16mm roller bearing hub attached with M16 bolts, plenty of washers - and locking nuts.
It makes it so easy and quick to move the complete scope from the garage, around the side of my house to the back lawn ( a couple of minutes as opposed to at least 25mins previously ). The collapsible design of the OTA is perfect for wheelbarrow handles as when its collapsed, the weight (centre of gravity) is low, and with the tension handles tightened up snug it is very solid with no chance of tipping unlike most dobs.
So far I have just left the handles attached for observing as they are painted white and can be seen with dark adapted eyes.
I made sure the height of the handles wasn't going to get me in an awkward part of the anatomy if I do walk into them in the dark!! But maybe I will hinge them to fold out of the way if I do - we will see.
I have done quite a few mods to this scope but so far I am really excited and very happy about this one. Its already resulted in me using it more often which is gold! - having a big scope deployed easily and under the stars observing is the key to having a big scope in the first place!
