Hi all so im in need of some blocks of aluminum steel anything you may have alot of. Start to get materials to do projects and figured it may be worth asking on here before i try buying from amazon or msc.

The other thing is im looking for 2 change gears for my SB 9A. I need the 2 gears to do some metric threading. Now i believe i found them on thingiverse that id be willing to try however i dont have a 3d printer.

A 127 tooth gear is needed for an exact metric conversion, but there are simpler/cheaper combinations, eg 37:47, that will get you to within the accuracy of your lead screw.

See http://www.loganact.com/tips/met-thd.htm or Screwcutting in the Lathe (Workshop Practice Series) http://amzn.com/0852428383 for more info.
