This 351W project has me messing with all kinds of stuff.  when I tore the engine down I threw together a quick a dirty tool to get the bearings out but I wanted something more professional to install the new bearings so as not to damage them.  Most of the tools on the market were either Chevy specific or universal... in other words "one size fits none"  I was about to give up and buy a universal tool when I found a video on youtube of a guy using a SBF specific cam tool with 5 pucks and a cone. (for those of you that don't know each cam bearing from the front to the back gets about .015" smaller than the one before it)  I new immediately that that was the tool I wanted even at $160.00 BUT I could not find one.  Every site that had them for sale listed them as "out of stock"   Not one to take no for an answer I decided to make my own.  I started by measuring all 5 bearing journals in the block then measured the bearing lobes on a cam.  I used the cam measurements rather then measuring the inside of the actual bearings because I figured the bearings might compress slightly due to the press fit once installed and I wanted to have a size that I knew could easily be removed from an installed bearing.  I then took a piece of 2.25" aluminum round stock cut it up into 6 pieces so I could machining them.  The first one replaces the cone and fits in the #1 journal without a bearing.  It has a hole in it to center the shaft when driving in bearings 5-2.  I machined the 5 bearing pucks biggest to smallest that way if I messed up and cut one too small it could be used for the next size down.  That turned out to be a good plan as I cut to much off of puck 3 which is now puck 4.  I then fabricated a steel cap that bolts to each puck and that the rod slides into, that way the head of the tool is removable to make it easier to use.  I am very happy with the result.  Did a test run with one of the old bearings and all worked as it should.  The entire project took me about 8 hours start to finish so with the $160 price of the one I wanted I was "paid" $20 an hour to make my own.  Not the best wage ever but it was a lot of fun.
