Making of inner matrix for bending tool, this one is oak and 210 mm diameter. Seen here also is a rotating tool holder for lathe, essential to form inner radius for this wheel. It is adjustable. Here set for 30 mm tube.
Combined bushing press and tube bender! Works like a charm. 30 ton press from Biltema. Inner aluminum matrix is 120 mm, used for a 150 degree bend for rear upper arm.
This was made from my old crane. It was very wobbly and used chain block direct over engine, that meant that crane tip was 2300 mm above floor. This new design does same job, lift height 1900 mm. Double strain on chain block thou.
Some general tools made to fabricate parts.
1. Bushing press combined with tube bending.
2. Engine hoist.
