Churchill Tool JD 42

Hi Ya'll,  Been making a tool that will allow me to adjust the valve clearances on the 5.3L V12 engine.  Fairly simple to make and from reviewing the manual a necessity when working on the V12's.  This tool is used to reach down and 'snag' the tensioner after the tension is released so the sprockets can be removed from the cam shafts. 
1/4" base plate being cut and shaped

Parts, battery hold bolts, black pipe and 1/4 steel base

Pipe welded to base plate, 'J' hook modified to fit and catch hole in tensioner



Completed JD 42 

I thought I'd add a picture from the ROM to give you a feel for how the tool is to be used.  Now heading out to the garage to make Churchill tool JD40 ;-)
Cheers,
Lynn
