Taking the rise out of risers

Risertech 10
Article by Noodelz

The frame I’m building with right now has a 6″ downtube and 4″ backbone stretch so needless to say it’s kind of a “stretch” to get the bars with short straight risers. So I piscked up a set of 4″ with 1″ pullback to get my bars back towards me. They were too high but had the right pullback so I shortened them to where I wanted them.

First I used a hardened and ground parallel on a granite table against an angle plate so I had a square base to scribe on. The parallel is 6″ and I took 1.125″ off so I set the vernier height guage to 7.125″.

Then I scribed them and chucked them up in the lathe to part them off at exactly the same place on both.

Now they’re in two, time to get my center and scribe it out using a center finder from a combination set.

Now that I have center I center punched them and put them in a drill press with a dead center in the spindle to line it up with the center punch mark.

Once I had my depth set I drilled with the tap drill size for a 1/2″-13 which is 27/64″. Then I levelled them out in a vise and tapped them with a bottoming tap so I could get threads all the way to the bottom.

Finished product, now I have the rise and pullback I was after so I didn’t have to get my arms extended like Stretch Armstrong….
