Now that the base is nearly complete, the wheelbarrow handles are next on the to do list. Months ago I measured and cut steel tubing left over from the tailgate, then welded it into handles shaped like a dog leg. This way I won't have to stoop as far when it's time to roll the telescope. I marked and drilled holes to hold the stainless steel eyebolts that will thread into threaded inserts that I will put in the rocker sides. I'll bore them out to 7/16th of an inch to make threading them into the inserts in the rocker box sides easier. The steel handles will be painted with glossy black enamel paint. The eye bolts will be retained in the handles with stainless steel all-metal lock nuts. A larger hole at the end will hold a 1/2-inch bolt that will attach the wheel to each handle. For those I'm going to use a 10-inch pneumatic or air-filled wheel with a 1/2 ball bearing hub, the sort that is used for hand dollies. Eventually I'm going to put some foam rubber on the handles so the steel tube won't be so cold on the hands after a winter night of observing and some bumpers to protect the finish on the sides of the rocker box.
