Re: 1986 Chevy C10 SWB Step Side
Been working on cutting the original front springs one coil off the bottom. Used a portable band saw ( hand held, made by Porter Cable) to cut the coil off. The cut was made perpendicular to the length of the spring. Cutting this way provides a flat area on the bottom of the spring to fit in the lower control arm spring grove like the spring did before cutting. This way, the spring will have less tendency to bend in a arc as it compresses.
This is a very slow cutting process, and I used a home made clamp/ bar to bolt the spring to work bench for cutting. The bar/clamp was a 6 inch piece of bar stock ( 1.5 " in width) with hole in center, spring placed on bench, "clamp" placed inside spring, bolt placed through hole in bar stock, spring, and through bench. Nut placed on bolt under work bench, and tighten down, thereby, securely holding spring FIRMLY to bench. Marked cut line perpendicular to length of spring, so that the beginning of cut is parallel to original end of spring ( this way it will fit in lower control arm in same rotational orientation as before cutting one coil).
Pictures of spring after cutting, cleaning in media cabinet with alu oxide 120 grit, then painting with gloss black ( actual paint used to be provided).
Next will start assembling suspension.
