Re: [Rolling Ball Sculptures] Re: Any tips on soldering tracks instead of wel...
- I used brass welding rods in 3 feet lengths and
soldered them with flux and solder. They were strong
if not banged around too much. I did have some balls
that would jump off, but I usually added railing. I
took small pieced about 1/2 to 3/4 inch long and bent
them about 30 degrees. These would be my spacers to
keep the track together and provide better rigidity.
I have made several machines, the first ones though i
used copper coated steel rod, but after time it rusted
at the joints. The brass didnt rust and it actually
looked better. I bent all of my track by hand, first
doing one rail then bending the second rail slightly
different depending on if it was an inside or outside
turn. I used aligator slips to hold it apart while
soldering on the spacer clips and once I had gotten
the first track in place and the supports all welded
on, it got much easier. My tracks were all at least
12 feet in length and could've been longer if I had
just kept adding the 3 ft lengths. Hope this is
good info for you... :)
