| Last year I replaced the heads on my Shovel
with new STD heads. These have 3 bolt exhaust flanges where the
stock ones only have one bolt per flange, so I had been intending
to make matching flanges on my pipes for a while, this winter
I finally found the time to do this..
| I started with a little sketch on paper,
which I used to make a CAD model that I could send to my CNC guy.
The flanges start at 1.75" where they exit the heads and
taper out to 2", leaving enough room for the mounting bolts.
2 weeks later I had some shiny new stainless flanges, which I
testfitted first to make sure they would fit. They did,
| I marked the cut on the pipes, removed
the old flanges and Rene (of Just Fubar) did a great job TIG welding
the new flanges on. I cleaned the welds up, and decided I wanted
to safety wire the exhaust bolts, so made a little jig to drill
the heads of the bolts. Ok, next project!
