reconstructing vintage mufflers
|
Here's a job we did in 2007.
This project started as a box of disassembled rusty parts of a pair of '54 Norton Dominater original silencers. These silencers have compound curves and are in left and right hand halves welded together along an external seam. Here are the 4 new parts of steel cut to shape ready to be rolled . The main section has the edges folded to duplicate the seam.
|
|
TIG Welding
|
After rolling the parts are then carefully TIG welded together.
|
|
panel beating.
|
While welding the side is panel beaten to a nice rounded shape. The tail pipe is added later.
|
|
Hand filing
|
The high spots are hand filed in between panel beating until the shape is just right. Can't file too much off!
|
|
High speed sander
|
The part is sanded with progressively finer grades until it is polished
|
|
nicely shaped
|
A nice shape which started as a flat piece of steel. Next the tailpipe is added, baffles inserted and the halves welded together. Sounds easy doesn't it!!!
One of these days we'll post pictures of the completed project bike.

Ready for chroming

The mufflers ready for polishing and chroming. There is still a part left over perhaps for future use.

We met up again with the owner, James lynch, at the 2010 Sound of Thunder meeting, Ruapuna, and he subsequently sent us a photo of the finished project. Hasn't he made a great job.
