I have cast risers before, but found that the accurate machining of the cast part was difficult (the tapped holes and bar clamp area). I am trying another way here. This started out as a square billet chunk, with the holes already machined. Then I carve away the excess material by hand with a rotary file. This still gives me complete creative flexibility but ensures better accuracy. This pair took just about 20 hours.
