I like your Optical Drive rescue-rod better cause it's free, but drill rod might work if you can't find a suitable drive to salvage

Optical Drive salvage for 3mm hard steel shafts
So if you ever see a dead computer optical drive, CD or DVD player, or Bluray player, don't pitch it!
Take it apart, and there are a variety of motors and belts and stuff for robot makers. Not interested.
However, there will be a pair of 3.00 mm hard steel shafts that the laser guidance system runs on that could be very useful for anyone who has bent a small motor shaft (which would be me, several times). Nearly all 400 size brushless motors use 3 mm shafts which are otherwise very hard to find (as in, impossible).
Sure you can get the replacements, but they're just as soft as the original junk. The rest of these <$10 motors use decent quality magnets, bearings, and windings, and run well. But in my experience, a hard landing (even with prop saver!) can bend the shaft.
Dead CD player to the rescue!
I have honed down 1/8" music wire (ok) and K&E SS (better) with ok results, but CD player guides are the cat's meow.
You also get a couple of super powerful rare earth magnets from the focusing lens.
If it is a dead bluray, it has a real cool laser diode. check the internet for lead diagram, and don't fry it like i did!
