Jan 2010 Lower wishbones - plate fabrication

For my lower wishbones, they are significantly more complicated than the upper ones.

First i drew out my wishbone design full size on card and then when i had my design in full scale for the plate, i traced it and transferred it onto card. 

I then welded together 2 pieces of 4mm steel plate and taped on my cardboard template.

Then using the template as a guide, i used the bench drill to drill the hole centres and punch holes around the outline. Once i had finished all the drilling, i could cut out the basic shape more easily with a cutting disc on the grinder. Then just tidied up the edges with the flap disc and seperated the 2 plates apart.
