Good day tractor lovers,

     I've been so busy with other things over the last year or two that I've

kind of slacked off on my 1930 John Deere D project.  I still read much of 
the ATIS mail but have been pretty much in "lurk" mode for a while.  Anyway,

I have decided that it is high time to get back at it.  The big bottle-neck 
for this project has been the cylinder block - it needs boring and sleeving 
and that is a big job.  I bought the sleeves several years ago so it's the 
machining that is holding me back.

     Last weekend I decided to get at it.  My plan goes something like this:

  The sleeves measure 7.000 on the outside and 6.720 on the inside.  The 
inside is about 0.03 under the standard JD bore size of 6.750.  This is to 
allow to finish boring and honing after the sleeves are pressed in.  What I 
will do is try to clean-up the bores at about 6.730 or 6.740 and turn my 
pistons down a bit to fit - that way everything is machined new.  Of course,

I will have to size the ring-gaps to suit, but that is minor.

     The job is only half done as all I did on the weekend was bore the 
block, but I did take some pictures that some of you might find interesting.

  Hopefully I will have more pictures of the whole process soon.
