 | Time: 1.5 hours Cut three lengths, 45mm, 40mm, 15mm using mitre and hacksaw Locate hole for bolt by putting masking tape on bottom, and marking centre line front to back. Place upright in position and place nylon block in position. Mark centre of block front-to-back on the tape. Double-check centre, mark the location of hole on tape. Drill 4mm hole Assemble parts and glue as shown, ensuring 'T' is square and using the block to locate the upright left-to-right position. When dry, drill the three 3mm mounting holes as shown Using the rotary tool with cutting disk, cut away lower support (marked red) to avoid interference with the subchassis. Drill a pilot hole for the spring hanger screw into the centre of one smooth face of the suspension block. Arrange washer, spring loop, washer on the screw thread, and screw into block.

 | Improvements You may wish to have two side walls to the suspension mount to securely locate the sliding suspension block. To do this you need to cut a more complicated pattern from the carbon fibre right-angle sections.
