The initial materials. Four 1" square beams, one 2"x3" beam, and a
variety of fixings and fastenings.
|
|
2"x3" blocks make the bearing for the axle. They're hinged onto the
A-frame beams.
|
|
This allows the A-frames to be unfolded for convenient storage.

|
The first A-frame.

The swing arm, drilled for its bearing.
|
|
The arm is reinforced, and the bearing is inserted.
|
|
The base bars need cutouts to hold the A-frame.
|
|

|
|
...but nothing that a chisel can't solve.
|
|
It fits!
|
|
...and is drilled for its retaining bolt.

|
Base bars completed, test assembly.

With spacer bars (to hold the sides at the right distance apart). Wedges
for A-frame top are visible below.

Wedges in place and reassembled.
