And decking the block with liners in place is difficult as they tend to
'rock' as the stone goes by. Just something else to worry about...Alan T
You are right about the liners wanting to move when they are milled in the
block. At the time I did this, I had an excellent machinist who was able
to accomplish this task. While this set-up worked fine for a while, the
problem came the first time I had to change the liners (i.e. the new liners
were too tall for the block). I eventually ended up pitching the block
which had been milled and went back to stock blocks. I had parted out
enough engines that I could always find a block with a good top surface,
and enough good used liners which I had bored out.
By the way, I now have the boring machine and fixtures that my machinist
used to use to bore liners. As soon as I get it set up and figure out how
to use it, I will be able to bore TR-2/3/4 liners individually.
When having liners bored, I would always clean a set up first and fit them
to the block I was going to use, just to make sure they would 'stand proud'
of the block sufficiently, before investing the money to have them bored.
