>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.
