Stem knurling alternative
Posted: 08:08 am May 19 2018
For those of you looking for a alternative to having the steering stem knurled, I may have found a solution. I feel like a bit of a tool posting this, because I am a machinist..... So knurling should be a piece of cake! Yes, but the shop I work at is so busy I've been waiting for 2 months for a lathe to use for an hour!
So, I got thinking about it, and since knurling just displaces metal, why not use a little elbow grease and go to town with a hammer/punch. So I tried making a few punch marks around the O.D of the stem, and sure enough the edges around the indents are raised enough to prevent it from sliding into the lower triple. Later on when I have more time I'll do staggered rows of punch marks, then press it in and report back. But as of now it looks very promising.
