Whippet Seat Post


 

I didn’t have a lot to go on for the Whippet seat post. The Whippet drawing shows a straight seat post, so why does this one have a kink? If the factory wanted a bend, it would have been a smooth bend. I chose to ignore the kink, but I did like the shape of the top clamp.

I used a piece of 954 bearing bronze. As long as the cutting tools are very sharp, machining is not a problem.

After drilling 2 holes, the block is turned, and the centre milled out.

The block is now mounted on a spigot, and spun in the lathe. I machined the top of the clamp at an angle and included a crude radius for the top.

At this stage, I really wasn’t sure what the bronze caps’ final shape looked like.  I started the hand filing process and the shape emerged as I worked.  Below is the seat post: non-adjustable and fillet brazed.

I was pleased with the end result. The seat post will get bead blasted and nickel plated. An old fashioned square bolt will replace the modern hex bolt.

Thanks for taking the tour,
