• An engineering company is going to charge you shitloads for 2 parts.

    A good idea is to find someone you know who's at a college involving lathes and ask them to knock them up for you. I had to learn how to use a lathe as part of my uni course, they gave us a week to build a high pressure, air powered, single piston engine. I had it done in 3 days and spent the rest of the time making a new seatclamp and fancy bolts for my BMX.
