My Dynamometer Drum Information and Pictures

(If you click on any of the images for a bigger picture, just click the larger image to close the window.)

Here are some pictures of my "drum". I bought a lump of K1045 round bar for $1676.40AUD (inc GST) back in 2000. It was 460mm (~18.1") diameter round bar 600mm (~23.6") long. I then got the sides machined down to 80mm X 120mm stub axles, (do you think I feel sorry for the machinist that had to sweep away approximately 150kg of swarf from each side?). The machining cost $528AUD (inc GST). I also had the surface machined with a cross hatch for traction. All radii were specified by me. I ended up with a drum 360mm wide with a diameter of 460mm and 2 X 80mm X 120mm stub axles. Final weight came to 478kg (1054lbs), raw weight was 780kg (~1733lbs). The pillow block bearings (CBC UC216) cost another $300AUD.

So that's 460mm in diameter X 360mm wide and weighs 478kg. MOI comes in at 12.6513kg/m2
