Although a seemingly small change, building a new seat support took several hours to complete. Here's a sequence of photos showing how it was done.

 

 

 

 

At left is a view beneath the seat, making it easy to see how far inward the extensions had to go to attach to the frame. It got the job done but needed to be replaced.

 

 

 

 

 

 

At right you can see a pair of 1/8" steel strips cut to length, drilled to match the stock mounting holes and bolted down.

 

 

 

 

When I originally mounted the seat, shown at left, I built crude extensions to hold the seat and sliding tracks using the stock mounting holes. The result was ugly, heavy, and scraped the back of my leg every time I got on the bike. Something needed to be done.
At right is a close-up of the extensions, made with square tubing and a piece of angle welded together and sticking right out. Just imagine how painful a scrape from this would hurt.

 

 

 

 

 

 

 

 

At right the clamped assembly is fitted to the frame to make certain everything lines up where it should.

 

 

 

 

 

 

At left the new sliding track assembly is tacked into place. You can also see braces welded beneath the strips to keep things from sagging. The welds aren't the prettiest but provided good practice time.

 

 

 

 

 

The seat was  bolted down for another test fit and passed with flying colors. I'll have to remove the seat again for the final welding, followed by deburring the various pieces and a coat of primer.

 

 

 

 

 

 

Here's the finished assembly. New upholstery is scheduled for the future, but right now a simple tuck underneath secured with some hog rings will suffice.

It took about five hours to design and fabricate the new slider, but makes a big difference. It looks better, weighs less, and hopefully eliminate any more scraped legs.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

At left are the sliding tracks clamped to the metal strips. Keeping the tracks parallel was important to make sure they slid back and forth without binding.
