How To: C15a Wire-3 restoration

[Jordan Baker]

Today I finished installing the manifolds onto the block. I then began adding the throttle linkages. On the original block there was a small shaft for holding the return spring. On the block I’m using there wasn’t one. However there are threaded holes for side mounts in the right position. So I decided to make up a threaded shaft that can simply screw into the hole. Once done it will easily do the job. I wanted to put in a small grove for the end of the spring to sit in. Since I don’t have a lathe of my own yet I rigged up something in the drill press. I mounted the shaft in the drill press, then my dremel in the vice. I put a small diamond cutting bit in the dremel and turned it and the drill press on. I then simply turned the vice in and let the spinning things do their thing. Everything worked great and the part will was I do what I wanted it to do.
