Walker 740 Jack

Walker 740 Jack from 1927. I have one that was very rusted. After cleaning it up, I created this model to replace broken parts. The model does not include springs, bolts, or nuts. All measurements were taken from a working jack that is nearly 100 years old. Measurements are approximations at times. The original is mostly cast iron. There are going to be differences between physical samples. Note for future persons - The roller bearing for the front wheels can be sourced from McMaster-Carr under part number 98381A630 Dowel Pin Alloy Steel, 3/8" Diameter, 1-3/4" Long. Ratchet springs 2.25mm Main spring McMasterCarr 9657K437 .7 or .75 x3 Forward bolts - 3/8x1.25 (8) wanted shoulder .5 -.7 Caster Bolts - 3/8x1.5 (8) wanted shoulder .9 -1.0 Handle Bolts - 3/8x1 (4) wanted shoulder .5-.7 Lifter pusher 3/4x 2 (1) wanted shoulder 1.5
