Spade Grip Build Tutorial 3
Notch the top plate to fit around the lug on the backplate, make sure
the plate does not extend past the lug.
Now align the lower brackets with the trigger slot and clamp in place.
The top plate should be aligned with the lug on the backplate and
sitting on the plate. If the alignment is correct it is ready to weld. Leave the
grips in place and tack the assembly together. Since the backplate is cast,
you will need to use an alloy rod like E301 to weld it with.
Once the parts are tacked together if the alignment is correct, remove
the grips and finish welding.
