Modifications to shop tool Matra 282

I bought a Matra 282 tool from Vech, which removes the rear bearing of /2 cranks.

The tool is good but it has a few quirks.  On Saturday, I asked Joe Groeger to help me modify the tool to make it work better.  He came up with some brilliant modifications.  

He chamfered the edge of one of the halves to help it slip into the slinger easier. 

I found that the tool wants to rotate when in use.  Joe milled two flats into the "nut"... I can keep the entire tool steady with a 22mm wrench. 

Making and modifying tools is pretty cool !

Joe has made his own rear crank bearing puller and it looks like this:

And is used like this:
