Continuing with the new stainless steel manifolds, we driled and tapped the flanges and bolted the stock manifolds to them to use as templates. Aad scribed the oval contour into the new flanges, then cut away the rough shape with an angle grinder.

The precise shape was made on the belt sander using the scribed lines as reference.Next we drilled the manifolds for the vacuum tube that connects them to each other.

After the bungs were welded on, the holes wee drilled to the correct dimension and then tapped. Instead of using nuts and bolts to mount the carbs we welded in threaded studs for a cleaner look. Then came a lot of grinding, filing and sanding.


All the pieces including the stainless mounting hardware were then polished by Aad, quite happy how these pieces came out!
