Have you ever been working on your motorcycle/car and figure out you need a special tool for that one nut or bolt? Instead of buying it from the dealership, why not make it yourself?  This Instructable covers making the tool to remove the oil filter nut on the 1976 Honda CB500T.  This may also be the same tool for the other Honda Twins of the 70s.

I made this tool at Techshop SJ.

Step 1: Parts and Tools

To start off you are gonna need a few tools and supplies:
  • 13/16 " spark plug socket
  • Angle grinder
  • Angle grinder Abrasive wheel
  • Dremel tool
  • Dremel grinding stone
  • (Optional) Vertical Mill
  • (Optional) 1/4" Carbide End Mill
You don't need to remove oil filter for oil change, it's just a cup fitted to end of crank. It works by centrifuging dirt out of oil, the more rpm your doing, the better it works <br>It's wise to remove the end cap around 5,000 miles and cut/scrape out the almost solid mass inside filter, forms a layer which is relatively easy to remove, looks a bit like oily cardboard
Same tool is used on CB/CD 175, CB/CL250/350, CB/CL250/360 and the DOHC CB450
